Fisheries and Aquaculture Department, Food and Agriculture Organization
of the United Nations
The Food and Agriculture Organization of the United Nations (FAO) has a long tradition of promoting responsible fisheries throughout the world; 2015 marked the 20th anniversary of the
FAO Code of Conduct for Responsible Fisheries. The code is a landmark of international cooperation and agreed set of guidelines and principles to help develop, manage, and conserve the
world’s fishery resources for the benefit of present and future generations. However, more is
needed, especially for the world’s inland fishery resources and the habitats that support them.
The FAO and our global partners are facing numerous challenges in regards to inland aquatic
ecosystems and their fishery resources.
Probably the most significant challenge is the competition for freshwater resources. Currently,
about 9% of the freshwater from rivers, lakes, and groundwater is withdrawn for human use. Seventy percent of this water is abstracted or diverted for agriculture, industry takes another 20%, and
domestic uses account for another 10%. These withdrawals have significantly degraded the aquatic
habitat and fishery resources. However, agriculture is a key player in global efforts to reduce hunger
and poverty. Fisheries and agriculture need to become closer partners. Fisheries are often called a
“nonconsumptive” use of water. This is not exactly true. If you manage a river for fish, you may lose
or reduce the use of that water for hydroelectricity or irrigation. The fishery sector needs to communicate win–win situations where people can have fish and irrigated agriculture and electricity.
Happily, there are examples, and these need to be communicated more broadly.
Dealing with the multiple users of freshwater is essentially a governance issue. However,
international and national efforts to fully integrate inland fisheries into the broader governance
and development agenda have not been overly successful. Important publications and processes
have given much more attention to domestic uses of water, to marine and coastal issues, or to
agriculture production over inland fishery production. The FAO and partners are now striving to
help bring all food producing sectors together in a synergistic manner.
A necessary component to support governance is adequate information. More than half of
the catch from inland waters is not reported to species—we do not know how much and we do
not know what is being captured. The FAO has a special strategy for improving information on
status and trends of capture fisheries to increase the knowledge base.
However, inland fisheries are more than metric tons harvested; what this harvest contributes to nutrition and livelihoods is the important factor. Fish provide significant and affordable
protein, minerals, and micronutrients to millions of people in developing areas. A small, freshwater fish from the Mekong River about the size of an index finger can provide a child’s daily
requirement of iron and zinc; similar small indigenous species of fish are a valuable component
of people’s diet and culture around the world.
The health of our planet, our own health, and future food security depend on how we treat
aquatic ecosystems. To provide wider ecosystem stewardship and improved governance of the
sector, FAO is advancing the Blue Growth Initiative as a coherent framework for the sustainable
and socioeconomic management of our aquatic resources. Although there is a strong framework
for fisheries and aquaculture already in place with the FAO Code of Conduct for Responsible Fisheries, the challenge is to provide incentives and adequate resources to adapt and implement this
framework at local, national, and regional levels in order to secure political commitment and
governance reform.

foreword: food and agriculture organization of the united nations
The proceedings and recommendation of the global conference, Freshwater, Fish and the
Future, will contribute substantially to this global initiative and the core work of FAO and other
United Nations agencies. The partnership between FAO and Michigan State University, formalized at the conference, will help to further promote the principles of responsible fisheries and
blue growth. The Fisheries and Aquaculture Department of FAO is pleased to be a partner in this
endeavor and offer the information in this book to those charged with developing, managing, and
conserving the world’s inland fishery resources.

Foreword
Michigan State University
Inland fisheries have long been a quiet but vital component of food and economic security around
the world. Yet the voices of those most dependent on inland fisheries often are drowned out by
louder, more powerful interests competing for aquatic resources for use in agriculture, energy,
and economic development.
We believe that inland fisheries and aquaculture have a great capacity not just to sustain
poor and disadvantaged communities around the world, but to elevate them. That is why I was
pleased to be in Rome in 2015 to help open the global conference on inland fisheries. This conference brought together experts from various sectors from more than 40 nations, including a large
number of early career scientists and women (40% female speakers), because the challenges
facing inland fisheries require new cross-sectoral approaches and the involvement of all stakeholders in freshwater resources.
We need to elevate the profile of inland fisheries and aquaculture in global discussions on
food and economic security and on sustainable land development and water management. Based
upon the thought-provoking presentations and discussions at the Rome conference, a set of recommendations—10 steps to responsible inland fisheries—were developed that we hope will
provide the foundation for a new international approach to ensuring that the true value of inland
fisheries is recognized in resource allocation decisions.
Back home in Michigan, we are acutely aware of the fragility of freshwater fisheries. Our
waters have suffered greatly from pollution, overfishing, and the introduction of invasive species.
Our experience in restoring the Great Lakes across boundaries and borders provides a great example of the power of international partnerships and cooperation.
Beyond the conference, Michigan State University (MSU) and the Food and Agriculture Organization of the United Nations (FAO) are strengthening our relationship through joint studies
linking societal well-being and food security to the quality and quantity of freshwater habitats
and local fish populations. On behalf of FAO and MSU, Árni Mathiesen and I signed a memorandum of understanding to collaborate on inland fisheries educational programs. This includes resource mobilization, capacity building and training, new faculty, internships, fellowships, visiting
scholars, and sharing and disseminating information while advocating for our common goals.
Inland fisheries represent an important component of a growing, global blue growth economy. This conference proceedings serves as a roadmap demonstrating how to assess the world’s
inland fisheries and freshwater resources and how to optimize and protect them.

Preface
The purpose of this book, and the global conference (www.inlandfisheries.org), is to elevate the
significance of freshwater fisheries throughout the world so that fishery managers and the people that depend on freshwater fisheries will have a voice when policymakers make decisions that
impact their viability and productivity. All too often, inland fisheries are not appropriately valued
as to their critical role in food security, and worse yet, they are not even considered when policymakers decide on the use, allocation, and alteration of freshwater resources in their communities
and nations. When governments decide to build dams for power generation and flood control,
the impacts on the nearby local communities and on the freshwater ecosystems are too often not
considered or, if considered, not valued appropriately. Much of this is due to the fisheries community not being able to provide accurate assessments of the fisheries or the needed economic
metrics that allow for decision makers to make informed decisions as to overall costs and benefits of their decisions related to the use of their freshwater resources. In addition, the oftentimes
multijurisdictional nature of freshwater systems further complicates decision making given the
differing priorities of the various governments that control the water and allied fish habitats that
provide the basis for the productivity of local and regional fisheries. The information in this book
highlights the importance of freshwater fish, their habitats, and their fisheries to society. The
intent of this book is to describe the current state of the knowledge and future information needs
that will allow for fisheries sustainability, which in turn directly or indirectly provides for the
health, well-being, and prosperity of human communities throughout the world.
It has been a distinct pleasure to interact with such dedicated and innovative fisheries and
water professionals and allied policymakers to enhance the visibility and importance of freshwater fisheries to the world. In particular, the phenomenal cooperation between Michigan State
University and the Food and Agriculture Organization of the United Nations (FAO) is particularly
noteworthy, as without each other’s support, a project of this magnitude could not have happened. At Michigan State University (MSU), the unfailing encouragement and support of President Lou Anna K Simon was critical in mobilizing the resources to not only design and implement
this ambitious program, but to design a future memorandum of understanding with FAO (see
www.inlandfisheries.org) that should enable others to continue the momentum that this conference and book established. The FAO has realized that developing and managing the world’s
freshwater ecosystems for improved food security and poverty alleviation is a task no one organization can accomplish on its own. Partnerships will be essential in meeting the United Nations’
sustainable development goals, as well as fulfilling the mandate of FAO. Mr Árni Mathiesen, Assistant Director-General of FAO Fisheries and Aquaculture Department, was aware of the importance of raising the profile of freshwater fisheries throughout the world and, like MSU President
Simon, gave full support to the conference. We also had tremendous support from the American
Fisheries Society and, in particular, Beth Beard, who designed the needed communication products that provided and continues to provide essential information in a user-friendly format for
all to access via the Web interface. Additional support was provided by the Australian Centre for
International Agriculture Research and the Great Lakes Fishery Commission.
No project is ever accomplished without many people providing innovative ideas and just
plain hard work in making things happen. There are numerous people from around the world
that were instrumental in making the conference and this book a success. In particular, we must
acknowledge the steering committee that worked diligently to ensure that this ambitious conference would occur and provided the platform that was needed to improve our understanding of

preface
the state of the global fisheries resources and the informational needs that allows for their future
sustainability. These include those people that were members of the organizing committee and
the steering committee and the panel chairs, who are listed at the end of this preface. It is with
deep gratitude that we acknowledge the efforts of Drs. Christopher Goddard and Nancy Leonard
for their lead on facilitating the editorial process of this book. Each spent numerous hours working constructively with the authors to make this book as complete and representative as possible.
Additionally, Dr. Leonard spent four months working on assignment at FAO, where she helped
with the myriad details related to this conference, which were essential to its successful execution and future value. Her adept people skills and intimate knowledge of multistake holder, multijurisdictional fisheries, and aquatic resource management provided essential ingredients for
the success of the global conference and this book. Bill would like to thank his colleagues in the
American Fisheries Society, in particular the Past Presidents’ Council, his colleagues at Michigan
State University, and his current and former graduate students who have inspired him throughout his career to dream big and act bigger to improve the state of the world’s freshwater fisheries
and their habitats. Last, no person is an island unto themselves, and without the unfailing belief,
love, and support of Bill’s wife, Evelyn, and his English springer spaniel, Teddy, this project would
never have been completed. Devin would like to gratefully acknowledge the support of colleagues
throughout the world and at FAO (especially Robin Welcomme, the former chief of the Inland
Water Resources and Aquaculture Service at FAO), who gave up their valuable time to make the
conference a success. The conference would not have been possible at FAO headquarters without
the daily administrative and logistic support of Ms. Cristiana Fusconi and the enthusiasm of Mr.
Felix Marttin. It is our hope that we have contributed to enhancing the visibility and value of the
global freshwater fisheries resources, and through these efforts, freshwater fishes remain an ever
present feature of the aquatic landscape and a highly valued component of human civilization.
For we believe as fish go, so go humans!

The Rome Declaration: Ten Steps to
Responsible Inland Fisheries1
Step 1: Improve the Assessment of Biological Production to Enable
Science-Based Management
Accurate and complete information about fishery production from inland waters is lacking at local,
national and global levels. Governments often lack the resources or capacity to collect such information due to the diverse and dispersed nature of many inland fisheries. There is much scope for
developing and refining biological assessment tools to facilitate science-based management.
Implementation recommendations
•
•
•
•
•
Develop, promote and support standardized methods for the assessment of inland fisheries
harvest and aquaculture production including: data collection (including traditional [catch
effort monitoring] and novel approaches such as household and government statistical surveys), database management, data sharing, and reporting that
∘ Reflect diversity of fisheries, fishing methods, ecosystem types and local cultural context,
and enable intra- and cross-sectoral comparisons;
∘ Include commercial, artisanal small scale, subsistence, and recreational fisheries; and
∘ Include as far as possible the contribution of illegal, unreported, and unregulated fishing.
Support the development of novel approaches to collect inland fishery data, e.g., remote
sensing of habitat types and population densities linked to fish production models.
Incorporate inland fisheries and aquaculture into ongoing agricultural statistical surveys to
facilitate comparisons, and integrate information to support cross-sectoral decision-making.
Increase support for efforts to improve capacity of fishery resource officers to collect information on the sector.
Establish a minimum set of data requirements that would be practical for countries to collect
and that would allow cross-sectoral comparisons.
Step 2: Correctly Value Inland Aquatic Ecosystems
The true economic and social values of healthy, productive inland aquatic ecosystems are often overlooked, underestimated and not taken into account in decision-making related to land
and water use. Economic and social assessment is often difficult and valuation often limited. In
most cases, especially in the developing world, inland fisheries are part of the informal or local
economy, so their economic impact is not accurately measured in official government statistics.
Implementation recommendations
•
Apply the principles of the Voluntary Guidelines for “Securing Sustainable Small-scale Fish
eries” in inland fisheries and in so doing, recognize, respect, and support governance rooted

the rome declaration
Promote and support the adoption of approaches that include assessment of the ecosystem
services provided by inland aquatic ecosystems to value their contribution to ecosystem
health and societal wellbeing.
Ecosystem services should be valued along the entire value chain.
Step 3: Promote the Nutritional Value of Inland Fisheries
The relative contribution of inland fisheries to food security and nutrition is higher in poor foodinsecure regions of the world than in many developed countries that have alternate sources of
food. Good nutrition is especially critical in early childhood development (i.e., the first 1,000
days). Loss of inland fishery production will undermine food security, especially in children, in
these areas and put further pressure on other food producing sectors.
Implementation recommendations
•
•
Maintain or improve the accessibility/availability of nutrient-rich fish in areas with traditionally high fish consumption and/or high levels of under-nourishment and malnourishment by ensuring fair and equitable access regimes.
Establish fishery and water management plans that include maintenance of an adequate and
diverse supply of nutrient rich aquatic products.
Step 4: Develop and Improve Science-Based Approaches to Fishery
Management
Many inland waterbodies do not have fishery or resource management arrangements that can adequately address sustainable use of resources. Where management arrangements exist, compliance
and enforcement are often minimal or non-existent. This may result in excessive fishing pressure,
decreased catch per unit effort, and conflicts between fishers, as well as changes in the productivity of fishery resources. In some areas, reductions in fishing capacity will be required. To facilitate
fishery management, it will be important to improve access to and promote better sharing of data
and information about inland fisheries supporting the assessment–management cycle.
Implementation recommendations
•
•
•
•
Implement an Ecosystem Approach to Inland Fisheries.
Support effective governmental, communal/co-operative, or rights-based governance arrangements and improve compliance with fishery management regulations.
Modify or establish fishery and resource management arrangements to protect the productive capacity of inland waters and the livelihoods of communities dependent on the resource.
Where reducing fishing capacity is called for, establish appropriate social safeguards and
provision of alternative livelihoods for people leaving the fishery sector.
Step 5: Improve Communication among Freshwater Users
Information on the importance of the inland fishery and aquaculture sectors is often not shared
with or accessed by policy-makers, stakeholders and the general public, thereby making it difficult to generate political will to protect inland fishery resources and the people that depend on
them. Moreover, many misconceptions exist on the needs and desires of fishing communities.
Implementation recommendations
•
Building from the “Small-Scale Fisheries Guidelines” and other relevant instruments, use ap
propriate and accessible communication channels to disseminate information about inland

fish, fishers and fisheries to raise awareness of inland fisheries’ values and issues, to alter
human behavior, and influence relevant policy and management.
The fisheries sector should engage other users of freshwater resources and participate in
national and international fora that address freshwater resource issues, conflicts and synergies.
The fisheries sector should invite other users of freshwaters to participate in fisheries fora.
Step 6: Improve Governance, Especially for Shared Waterbodies
Many national, international and transboundary inland waterbodies do not have a governance
structure that holistically addresses the use and development of the water and its fishery resources. This often results in decisions made in one area adversely affecting aquatic resources,
food security, and livelihoods in another.
Implementation recommendations
•
•
Establish governance institutions (e.g., river or lake basin authorities) or expand and
strengthen the mandate and capacity of existing institutions to address inland fisheries
needs in the decision making processes.
Commit to incorporating internationally agreed decisions on shared water bodies within national government policies.
Step 7: Develop Collaborative Approaches to Cross-Sectoral
Integration in Development Agendas
Water-resource development and management discussions very often marginalize or overlook
inland fisheries. Therefore, trade-offs between economically and socially important water-resource sectors and ecosystem services from inland water systems often ignore inland fisheries
and fishers. Development goals based on common needs, e.g., clean water and flood control, can
yield mutually beneficial outcomes across water-resource sectors.
Implementation recommendations
•
•
•
Promote cross-sectoral discussions about the trade-offs and synergies of inland water development and management options that consider the inland fishery sector a partner in resource development in an equitable manner.
Identify and strengthen platforms and legal frameworks for multistakeholder-based decision-making and management.
Incorporate inland fish and fisheries into the post-2015 sustainabilitydevelopment goals on
water issues and include all ecosystem services provided by inland aquatic ecosystems.
Step 8: Respect Equity and Rights of Stakeholders
Lack of recognition of the cultural values, beliefs, knowledge, social organization, and diverse
livelihood practices of indigenous people, inland fishers, fishworkers, and their communities has
often resulted in policies that exclude these groups and increase their vulnerability to changes
affecting their fisheries. This exclusion deprives these groups of important sources of food as well
as cultural and economic connections to inland aquatic ecosystems.
Implementation recommendations
•
•
Protect the cultural heritage of indigenous people and their connections to the environment.
Ratify and implement the Indigenous and Tribal Peoples Convention of 1989 (ILO-160, as
xx
the rome declaration
well as the Universal Declaration of Indigenous Peoples and other International human
rights instruments.
Step 9: Make Aquaculture an Important Ally
Aquaculture is the fastest-growing food production sector and an important component in many
poverty alleviation and food security programmes. It can complement capture fisheries, e.g.,
through stocking programmes, by providing alternative livelihoods for fishers leaving the capture fisheries sector, and by providing alternative food resources. It can also negatively affect capture fisheries, e.g., introduction of invasive species and diseases, through competition for water
resources, pollution, and access restrictions to traditional fishing grounds.
Implementation recommendations
•
•
•
Adopt an ecosystem approach to fisheries and aquaculture management10.
Recognize the common need for healthy and productive aquatic ecosystems and promote
synergies and manage tradeoffs among fisheries, stock enhancement, and aquaculture.
Regulate and manage the use of non-native species in aquaculture development.
Step 10: Develop an Action Plan for Global Inland Fisheries
Without immediate action, the food security, livelihoods and societal wellbeing currently provided by healthy inland aquatic ecosystems will be jeopardized, risking social, economic, and
political conflict and injustice.
Implementation recommendations
•
•
Develop an action plan based on the above steps to ensure the sustainability and responsible
use of inland fisheries and aquatic resources for future generations.
The action plan should involve the international community, governments, Civil Society Organizations, indigenous peoples groups, and private industry, and include all sectors using
freshwater aquatic resources.

Inland fish and fisheries provide food security,
livelihoods, cultural and religious identity, recreation, and a source of income for millions of
people globally (Welcomme et al. 2010; Lynch
et al. 2016, this volume). Human connections
to fish and fishing have existed for millennia
on inland waters systems as diverse as the Mekong River (Voeun 2004) to the glacial lakes of
the northern United States (Bogue 2000). Given

the long-term importance of inland fisheries to
societies, the lack of attention given to maintaining their sustainability during development of
management policies and allocation decisions
for inland water resources is alarming yet all too
common. Further, globally, even the most basic
information about inland fisheries is generally
lacking, such as basic life history of important
food fishes, total harvest and production, total
contribution to employment and livelihoods,
2
beard et al.
and contribution of inland fish to nutrition
and human well-being (Welcomme et al. 2010;
Beard et al. 2011). When in-depth analyses
are attempted, the numbers reported often
underestimate the true contribution of inland
fisheries to society (Baran et al. 2007; Hortle
2007; Bartley et al. 2015). Increased pressure
on inland waters to support multiple uses,
such as the proposed damming of the Mekong
River system for hydropower (Ziv et al. 2012),
the diversion of water for municipal and agriculture use in California (Tanaka et al. 2006),
and the conversion of forests to agriculture in
the Amazon basin (Davidson et al. 2012), creates numerous challenges for inland fisheries
management. The development of improved
and integrated approaches (e.g., integrated
water resources management; Hooper 2003;
Grigg 2008) to understand the important role
of inland fisheries to society and provide better governance mechanisms that cross political and sectoral boundaries will be important
to ensure inland fisheries sustainability.
Inland fisheries are defined by Welcomme
et al. (2010) to include the exploitation of fish
from waters inland of the coastline. Inland fisheries range from the small-scale, local artisanal
fisheries that are commonly found in the developing nations to the high-technology and recreational fisheries commonly found in the industrialized nations (Welcomme et al. 2010). The
geographic scale of inland fisheries can range
from small ponds and reservoirs to the world’s
largest rivers and lake systems. Threats to inland fisheries include unsustainable harvest
(Allan et al. 2005; Post et al. 2002), but unlike
large-scale, marine commercial fisheries, the
majority of threats are external to the fisheries sector and threaten the broader integrity of
the hydroecological systems that sustain fisheries (Cooke et al. 2014). Inland waters are impacted and threatened by multiple activities,
including the development of hydroelectric
power, agriculture and irrigation, municipal
water use, mining and other resource extraction processes, navigation, and the modification of riparian corridors to support human
activity (Dudgeon et al. 2006; Vörösmarty et al.
2010; Beard et al. 2011). Consequently, the development and implementation of policies and
strategies for the management of inland waters that do not consider all freshwater-based
sectors are often detrimental to fish and fisheries. With a lack of reliable data about the status
of fish populations, harvest, and the economic
value of inland fisheries, it is often difficult for
inland fishery managers to engage effectively
in the decisions about water use (Beard et al.
2011). If inland fisheries are to be sustainable
into the future, the engagement of policymakers and decision makers across all sectors reliant on freshwater will be necessary.
Given the need to develop sustainable
approaches to inland fisheries management,
bringing together a cross-sectoral community
to identify and discuss issues specific to inland
waters is important to engage and incorporate
fisheries in water resource management decisions. To build this cross-sectoral community,
the Food and Agriculture Organization of the
United Nations (FAO) partnered with Michigan
State University (MSU) to bring those working on global inland fisheries together with
stakeholders from other inland water sectors
for a global conference on inland fisheries
titled Freshwater, Fish and the Future: CrossSectoral Approaches to Sustain Livelihoods,
Food Security, and Aquatic Ecosystems. The
ultimate goal of this conference was to identify science and management challenges to assure that inland fisheries become part of the
decision-making framework regarding use of
inland water. In January 2015, 205 scientists,
managers, and others from 48 countries representing the global community interested in inland fisheries and the inland water sector met
in Rome at FAO headquarters. The conference,
sponsored by MSU and FAO, was structured to
ensure global representation and interaction
between the sectors reliant on freshwater by
uniting participants among four thematic panels: biological assessment, social and economic
assessment, drivers and synergies, and policy
and governance. This partnership facilitated
global cross-sectoral discussion about the status and value of inland fisheries. The outcomes
of this discussion were to identify the science,
management, and governance challenges to
assure that inland fisheries become part of the
inland waters decision-making framework.
inland fish and fisheries
The biological assessment thematic panel
(see papers in Biological Assessment Theme)
focused on identifying traditional and novel
approaches and methods that could improve
biological production assessment, that are
scalable and effective, and that are feasible for
implementation in both developed and developing nations. Furthermore, a variety of biological assessment tools that are flexible and
robust need to be developed and validated for
gathering and analyzing the needed data. For
example, are there novel approaches that can
be developed, such as remote-sensing-based
approaches for estimating inland water productivity and fisheries harvest? Given that
aquatic habitats are the foundation of healthy
and productive fisheries, it may also be informative to develop proxies for productivity
based on environmental metrics. Additionally,
what are the best ways to track fisheries harvest in the recreational, commercial, and subsistence fishery sectors? Is there a meaningful
role for household surveys or fisher log books
to assist in providing some of the missing and
essential data? Do the same assessment techniques that work in rivers work in lakes? Is it
possible to standardize the minimum set of
information collected to allow for comparison
across jurisdictions and inform broader comparisons? To be truly effective, however, assessment information about fish and fisheries
must be informative in fishery and other sectors’ planning and decision making.
The social and economic assessment
thematic panel focused on improving understanding of the economic and societal value
of inland fisheries. The goal of this panel
(see papers in Economic and Social Assessment Theme) was to explore and develop
new approaches to determine the monetary
and nonmonetary value of freshwater fisheries, including their importance to human
health and nutrition, personal well-being,
and societal prosperity. Better assessing and
conveying the value of fisheries is expected
to elevate understanding about the role of inland fisheries in individual well-being and societal prosperity and stability. The increased
understanding of the value of these fisheries
will help provide a common metric for evalu-
3
ating alternative uses of these resources and
habitats. The panel focused the discussion on
developing methods that would value inland
fisheries appropriately, using either traditional market-based approaches or nonmarketbased alternatives. Additionally, the panel explored the important role of fish in nutrition
and emphasized a need to better incorporate
this role into discussions about inland fisheries. Finally, the panel investigated methods
and approaches to integrate and respect the
rights of stakeholders, ensure that gender-equity considerations are included in policy and
management decisions on water and fisheries
governance, and ensure that water allocation
discussions incorporate the frequently disenfranchised local community, many of whom
are involved in fishing-related activities on
a part-time or occasional basis and are thus
overlooked even in programs targeted directly at those involved in the fisheries.
The drivers and synergies thematic panel
(see papers in Drivers and Synergies Theme)
focused on the identification of multiple sectors relying on inland waters, such as industrial and human use, tourism, recreation,
navigation, hydropower, and irrigation and
how use of inland waters by these sectors
can either influence the sustainability or be
synergistic with inland fisheries. To ensure
long-term sustainability of inland fisheries,
the management of sustainable freshwater
systems requires making informed choices
emphasizing those services that will provide
sustainable benefits for humans while maintaining well-functioning ecological systems.
Given that many sectors reliant on inland waters focus on a singular service and operate
independently with no consideration of other
inland water sector operations, the development of meaningful communication opportunities and approaches across sectors that
emphasize a common language, valuation
scheme, and understanding will help ensure
that trade-offs are properly incorporated in
final decisions about water allocation. A creation of approaches that allow the development of goals based on common needs, such as
improved water quality, can lead to mutually
beneficial outcomes across water-use sectors.

beard et al.
The inclusion of all sectors relying on freshwater in governance and management frameworks, and in decision-making processes influencing freshwater use and allocation, should
help ensure informed decision making.
The policy and governance thematic panel
(see papers in Policy and Governance Theme)
focused on the identification of approaches
and methods to ensure that inland fisheries
are fully integrated into freshwater decisionmaking frameworks. Approaches that link inland fisheries management goals and science
directly with the needs of policymakers will
assist strategic decision making in better understanding the costs and benefits of their decisions, inform adaptive management, enhance
environmental justice, and result in enhanced
enforceable regulations for more sustainable
management of inland fisheries. Given that inland waters are interconnected and cross multiple political boundaries, using approaches
that encourage cross-boundary discussions
about the use of inland waters and its impact
on fisheries production is important to avoid
negative consequences to the food security of
people that are distant from where the water is
used for other human uses. To this end, there is
a need to better understand the opportunities
and constraints to cross-sectoral and cross-jurisdictional governance approaches and development of methods to assure that governance
decisions take into account the contribution
inland fisheries make to food security, human
well-being, and ecosystem productivity at the
local, regional, national, and global levels.
Modification of the world’s waterways has
occurred for millennia, with well-documented
impacts on fish and fisheries and the impact
on food security of local people. In almost all
instances, these modifications were made with
little knowledge or regard to the impacts to not
only the fish and fishery, but also the people
who rely on them (Lynch et al. 2016). With
some of the globe’s most food-insecure human
populations dependent on inland fisheries for
nutrition and livelihoods (Smith et al. 2005),
coupled with the cultural attachment of many
of the world’s people to fisheries (e.g., indigenous peoples, recreational anglers), development of more holistic approaches to ensure the
sustainability of inland waters, fish, and fisheries is necessary.
During this conference, the global inland
fishery community identified multiple needs
and science gaps that must be addressed if
there is any hope of rehabilitating, maintaining, or enhancing inland fisheries. A conference, however well organized and attended,
does not necessarily lead to action. Investment
in the science and management approaches
will be necessary to advance understanding of
the critical role of inland fisheries to sustain
inland fisheries for future generations. With
the current threats and modifications to some
of the world’s greatest rivers and the resultant impacts projected to their inland fish and
fisheries, understanding and conveying the
critical role of these fisheries to human society
and food security is essential to avoid future
losses. The global inland fisheries community
and their partners should continue the discussion at the appropriate venues and ensure that
the critical roles inland fisheries play are highlighted during discussions about the food–water–energy nexus. Strikingly, inland fisheries
were notably absent in the recent revision of
the United Nation’s sustainable development
goals (no mention under the water goal or the
marine fisheries goal; https://sustainabledevelopment.un.org/?menu = 1300).
This book is organized to reflect the format of the global conference. The Plenary Talks
section presents the talks that were given during the plenary sessions of the conference. This
section is followed by four sections mirroring
the four conference themes: biological assessment, economic and social assessment, drivers and synergies, and policy and governance.
Each of these themes begins with a review
paper that summarizes the background information and the challenges associated with the
theme and explores the topics that informed
the recommendations developed from the
conference. A number of key scientific papers
and case studies relevant to each theme are
also included. The Conclusion summarizes the
key recommendations arising from the global
conference, called “The Rome Declaration: Ten
Steps to Responsible Inland Fisheries,” and details a call for action.

Inland Fisheries: Past, Present, and Future
roBin WelComme*,1

This address is intended to set a background to the conference on freshwater, fish,
and the future by examining the nature of inland fisheries and how we reached our present
state of knowledge and offering possible directions for the future.
In 2012, records submitted to the Food
and Agriculture Organization of the United Nations (FAO) by member countries show that
inland fish catches reached 11,630,680 metric tons after a more or less linear growth of
3.6% per year since 1950. Most of this catch
came from Asia (68%); 23% came from Africa,
and the rest from the other continents. Even
within the various continents, yields were very
strongly distributed by country. For instance
in Asia, 90% of the catch came from only eight
countries, whereas in Africa, 18 countries contributed 90% of the catch (Welcomme 2011).
Nevertheless, inland fisheries continue to play
an important role in the livelihoods and food
security of large numbers of people in all countries of the world. For example, it has been
estimated that more than 56 million people
were directly involved in inland fisheries in
the developing world in 2009 (BNP 2009). Participation by recreational fishers is more difficult to assess, but recreational fisheries have
been estimated to involve 118 million people
in North America, Europe, and Oceania (Arlinghaus et al. 2015) and be worth £1 × 109 in
UK household incomes for 37,000 household
jobs (Mawle and Peirson 2009), €25 × 109 in

tation in the European Parliament 25 March
2004), Can$8.3 × 109 in Canada (Fisheries and
Oceans Canada 2010), and US$34 × 109/year
expenditures, retail sales, and license fees
(U.S. Fish & Wildlife Service 2011). In addition, the fishery for ornamental species was
valued at US$1.5 × 109 for both marine and
inland species in 1998.
In the beginning, fishing must have been
relatively simple. Inland fisheries have been a
significant source of food from very early on
in history, as attested by the variety of hooks,
harpoons, and fish remains that shows up
regularly in prehistoric sites. Many early river-based civilizations show fishing as a major
activity, and traditional controls on the fishery
are probably as old as fishing itself. More formally, China had fisheries regulation as early
as the beginning of Western Zhou Dynasty
(about 11th century B.C.) when the emperor
listed protection of fishery resources as an important national policy (Qiu 1982). In Europe,
the increased pressure on fishing through the
ages has been reflected in a series of edicts that
limited effort. As early as Etruscan times, a basrelief of a sturgeon was mounted on the walls
of the fish landing sites in Rome, allegedly to
indicate the minimum size for sale. In England,
in 1,000 A.D., Aelfric (Watkins, no date) writes
of the fisherman who reported catching “eels,
pike, minnows and dace, trout, lamprey and
any other species that swim in the rivers, like
sprats.” He stated that he cannot catch as much
as he could sell in the town and shows a great
reluctance to go to the sea to fish. Indeed, at
this time, Edward the Confessor was obliged
to issue an edict for the removal of fish weirs
in the Thames and its tributaries as they were
hindering river transport. Somewhat later,
King Henry the First died, reputedly of a surfeit
of lampreys, showing the importance of fish in
8
welcomme
court life. Measures to control fisheries in the
Thames even appeared in early versions of the
Magna Carta. In the 1600s, Colbert, minister
to Louis IV of France, was obliged to regulate
the minimum sizes of fish being caught in the
Loire and the Seine because of the intensity of
demand.
These attempts at legislation demonstrate
an early appreciation of the impacts of heavy
fishing on fish stocks, and until relatively recently, knowledge did not advance much beyond that. Systematic investigations of inland
fisheries began in North America and Europe
towards the end of the 19th century, when
sporting interest in salmonids, mainly Atlantic
Salmon Salmo salar and trouts, caused a surge
in studies on the behavior of the species and
development of techniques for stocking and
improvement of their habitats. At about that
time too, interest in the fisheries of the lower
Danube (Antipa 1910), the Rhine (Lauterborn
1918), and the Illinois River (Richardson 1921)
were expressed in publications that were precursors of work yet to come. For example, Antipa’s seminal work on the floodplain fisheries of the lower Danube in Romania already
described many of the features of floodplain
fisheries that were to be verified in the 1970s.
The deteriorating condition of northern
temperate inland waters increasingly caused
concern following the industrial revolution.
So poor was the condition of many rivers that
they were judged to be fishless in the 1950s. In
response, some government legislation regulating inland fisheries began to be introduced
in the mid-19th century. A number of institutes
were founded to study the processes regulating
inland fish and fisheries—the Research Institute of Fish Culture and Hydrobiology (Czech
Republic) and the Department of Fisheries and
Oceans (Canada) in 1921, the Freshwater Biological Association in 1929, the University of
Michigan in 1930, the Central Inland Fisheries
Research Institute (India) in 1947, the Istituto
Nacional de Pesquisas Amazonicas (Brazil) in
1952, the Inland Fisheries Institute in Olstyn
(Poland) in 1951, and the Instituto Nacional de
Limnologia (Argentina) in 1962.
The expansion of European populations
into the tropics from the mid-1800s onwards
sparked a growing interest in the fauna and
flora of these regions. The fascination with
strange and exotic life forms accompanied the
early explorers and a series of museums appeared across Europe and North America to
deal with the wealth of material arriving from
Africa, Asia, and Latin America. The Musée National in Paris, The Natural History Museum in
London, the Royal Museum for Central Africa
at Tervuren, and the Smithsonian Institute in
the United States all amassed large collections
of type specimens described by a series of noted taxonomists, including Boulenger, Valenciennes, Geoffrey Saint-Hillaire, and Richardson
in the late 1800s, a trend that persisted until
the late 1960s with workers such as Daget,
Greenwood, Whitehead, and Trewavas. This
phase tended to be purely descriptive of species
with little attention being paid to their behavior, biology, or ecology. New species continue
to be found and described, especially from the
larger tropical systems, and the importance of
correctly identifying the animals forming part
of our fisheries has not diminished with time.
Unfortunately, taxonomy is unfashionable now,
the major museums have been transformed
into houses of entertainment, and there is a
sad lack of competent taxonomists.
The earliest systematic study of a tropical
inland fishery was carried out on Lake Victoria in the 1920s. The fishery for Singidia Tilapia Tilapia (now Oreochromis) esculentus was
growing fast in the north of the lake, and the
mean sizes of fish caught were dropping. Michael Graham (1929) investigated the causes
for this and, by applying the emerging discipline of marine stock assessment, concluded
that the stocks were overfished. He also recommended the establishment of a research
institute for the East African Great Lakes. This
recommendation was endorsed by Barton
Worthington following his 1936 visit to the
East African Great Lakes (Worthington and
Ricardo 1936). As a result, the Joint Fisheries
Research Organisation was founded in what
is now Malawi and Zambia in 1950, followed
by the East African Freshwater Fisheries Research Organization, Jinja, Uganda, in 1947.
The Belgians had also founded a research institute at Uvira on Lake Tanganyika, and the
inland fisheries: past, present, and future
French on the Niger River at Mopti, Mali at
about the same time.
The concentration on limnology through
these early research years resulted in an increased understanding of the functioning of
lakes summarized by Hutchinson (1957) in A
Treatise on Limnology, and this drew attention
to the processes of eutrophication that soon
came to assume significance as one of the main
human impacts on lacustrine systems. Little
was known as to the functioning of large rivers at this time. Indeed, these were not considered appropriate for detailed research due
to the great difficulties with sampling and the
opinion that each river was different and generalization impossible. At this time, too, river
channels and river lakes were thought to be
distinct, mainly due to the highly modified nature of most temperate systems and the lack of
knowledge of tropical systems.
The tools available for research were still
primitive or lacking (slide rules and hand-operated calculators were still the order of the
day), statistics had yet to emerge as a dominant force in the interpretation of data, and
communication with libraries and other academics was slow and unreliable. As a result,
most studies were purely descriptive natural
history. The north temperate countries had
mainly concentrated on salmonids and the increasingly apparent problems with water pollution and recreational fisheries. In the tropics,
awareness was emerging about the importance
of inland waters for the provision of food. As a
consequence, research and management developed very differently in the temperate countries and the tropics. In the temperate zones,
the focus of research and management was increasingly on water quality. Rivers and lakes in
the developed world had been highly modified
by the 1970s, leaving little of the original structure and trophic state. Fishing for food had
generally declined, although Eastern Europe
continued to have some important food fisheries. Furthermore, large-scale changes in the
nature of aquatic systems were taking place
elsewhere. The world was about to embark
on two decades of concentrated dam building
with a proliferation of reservoirs and modification of the structure and flood regimes of the
9
rivers below them. Fish faunas, too, were being
modified with major transfers of useful species
around the globe for recreation, aquaculture,
and, in some cases, capture fisheries.
Through the 1960s and 1970s, international interest centered on the development
and management of the fisheries of the newly
independent countries and their equally newly
created water bodies. Research was conducted
on broad aspects of fish biology, on the succession of species as reservoirs matured and
on the behavior of fish in rivers. A series of
externally funded international and bilateral
projects focused on fisheries, fish biology, and
ecology. These included both management-oriented activities and academic exercises, such as
the International Biological Programme, which
led to the creation of increasing numbers of
national institutes. These were not confined
to Africa, as internationally and nationally
funded research was also developing rapidly in
Argentina, Brazil, and Colombia. Such research
is continuing and remains the major topic for
published work on inland fish and fisheries,
to date. It is questionable whether the continuation of basic biological studies is always
the best use of research funds, but it must be
recognized that much of this research is carried out as part of postgraduate studies and, as
such, leads to a growing awareness of the importance of inland aquatic systems in the coming generations of scientists and administrators. The considerable body of work that has
emerged has resulted in detailed knowledge of
fish reproduction, migration, larval drift, feeding, and growth of some species in some systems and an understanding of the functioning
of some aquatic ecosystems. By extrapolation,
this has created a generalized knowledge base
sufficient for the formulation of conservation
and management programs.
Statistical tools such as frame survey methodologies and improved sampling and analysis
techniques were also developed and expanded.
A number of United Nations-funded projects
executed through FAO investigated the various
reservoirs and some lakes, mainly in Africa,
predicting the possible yield and tracking the
evolution of the fisheries. For example, simple
predictive indices, such as the morphoedaphic
10
welcomme
index were then derived to help plan the future fisheries of the new reservoirs and dams.
This work led to a growing appreciation of the
fisheries of tropical systems as synthesized by
Rosemary Lowe-McConnell (1975) and exemplified in a number of books and review articles on individual systems (see, for example,
Sioli 1984 and Bonetto 1986). There was also
a concerted effort at training personnel from
the individual countries to intensify national
capacity to carry out research and data collection, and the foundations of fisheries research
institutes in many newly independent nations
date from these times.
The possibilities also opened up for collaboration between the individual countries
through FAO working with international institutions such as the European Inland Fisheries
Advisory Commission, the Committee for Inland Fisheries of Africa, the Indo-Pacific Fisheries Council, and the Comision para la Pesca
Continental Latino Americano whose various
working parties, seminars, and symposia gathered and interpreted the data that were being
generated.
A marriage of temperate zone experience
and data gathered from modified aquatic ecosystems and data from the relatively unspoiled
systems of the tropics produced a series of
models of ecosystem function. At this time,
descriptions of flow-regulated river floodplain
systems emerged based on synthesis of the various projects by Lowe-McConnell (1975) and
Welcomme (1979). These considered rivers
as integrated channel–floodplain systems—a
concept long inherent in the French terminology of “lit mineur” and “lit majeur.” There were
a series of major international symposia, including a highly significant meeting in Seattle
in 1980 and the seminal large river symposium of 1986 (Dodge 1989), which led to generalized theories of river function such as the
river continuum concept (Vannote et al. 1980.)
and the flood pulse concept (Junk et al. 1985).
A second large rivers symposium was held in
Pnom Penh, Cambodia in 2003 (Welcomme
and Petr 2004). The corollary to the improved
productivity with increasing area of floodplain
flooded was extended to fish catch, where
strong relationships between flooded area and
the amount of catch in the same or following
years emerged in many systems. This linkage
between fish productivity and flow regime in
rivers has since been extended to river-driven
lakes and reservoirs.
During the 1970s and 1980s, evidence was
accruing of the failure of simple stock dynamic
models in predicting the productivity of multispecies fisheries and the response to fishing of
the individual species. Some attempts in rivers
and lakes had been made to assess stocks of
individual species, but it became apparent that
the multispecies, multigear fisheries of the tropics did not conform to the concepts of maximum
sustainable yield then being applied to marine
fisheries. Although such calculations might
be valid for individual species, particularly in
the more stable environments of lakes, the responses of multispecies (and multigear) fish assemblages to increasing fishing pressure were
the progressive disappearance of the larger species from the fishery and their substitution by
successively smaller species—a process later
named the “fishing-down” process.
Fishing-down, which in inland waters
is not linked to trophic level as some marine
theorists propose, is strictly linked to species
length and has continued to this day when
many Southeast Asian, South Asian, and African fisheries are based on only the smallest
species and the 0 and 0+ year-classes. It is assumed that the increasing numbers of fishers
in many inland waters is driving the increase
in effort. The increasing numbers of taxa recorded from inland fisheries in most regions
of the world since the 1950s is consistent with
the predictions of the fishing-down model,
although it might also be explained by better
identification and reporting at the taxonomic
level.
The wealth of data from the various projects and working parties of the international
fishery bodies enabled relationships such as
the number of species per basin area to be established for various continents and the yield
from rivers estimated as a function of basin
area and river channel length. Relationships
and models were also developed that showed
the dependency of catches in rivers on the extent and duration of flooding. These explained
inland fisheries: past, present, and future
the considerable year-to-year variations in
river catch and indicated the extent of losses
that occur when flood regimes in rivers are
modified by damming, floodplain drainage,
and water abstractions (see Welcomme 2001
for review).
Similar relationships were also derived for
lakes and reservoirs, but these were far more
complex as yields per unit area are strongly
conditioned by a number of other factors such
as lake depth, richness of the water (conductivity/total dissolved solids), and size of the
water body. These show that small water bodies are generally much more productive, not
least because they are much more responsive
to heavy stocking. The enhancement of yield
by stocking small natural and artificial water
bodies has become a standard management
tool throughout much of the tropical world.
However, this is often pursued uncritically, and
it is difficult to quantify the cost effectiveness
of many individual fisheries.
By the 1980s, attention was shifting from
biological and ecological aspects of management to the social and economic implications
of fisheries. Funding was increasingly withdrawn by donors from basic biology in favor
of social and political institutions. This led to
attempts at the valuation of the recreational
fisheries in Europe and the documentation of
the importance of inland fisheries in the livelihoods of poorer peoples in the tropics. At the
same time, there was a growing realization of
the general failure to manage inland fisheries
using the centralized and authoritarian systems that were then widespread, and a trend
to various forms of participatory management emerged. There has been increasing experimentation with forms of comanagement
through collaboration between fishers and
their communities, local and regional government agencies, and other stakeholders that
have met with varying degrees of success and
continue to evolve today. These systems often consist of a mix of traditional and newer
forms of management whereby agreements
are reached on access, catch quotas, permissible gears, and mesh sizes and persist today
as the basis for management of the sector at
the fishery level. However, while individual
11
fisheries may well be best managed at the local level, many functions, such as research and
national and international agreements, remain
the domain of central governments and even
international bodies such as river and lake basin organizations.
Research, to date, shows the inland fisheries sector to be highly diverse. The ecosystems and habitats themselves are divided into
lakes, reservoirs, and rivers, each with a rich
subset of environmental conditions. Fish faunas are extremely diverse, with larger lake and
river systems containing many hundreds, and
in some case thousands, of species of various
size and habit. The fisheries that exploit the
systems range from subsistence through commercial to recreational, each with its own rich
variety of fishing gear and requirements for
management. The objectives of exploitation
are also variable ranging from basic provision
of food through income, taxes by governments,
recreational value, and conservation strategies, many of which may be in conflict. In addition to fisheries, there is a rapidly increasing
pressure on the waters that support the fish
for a range of other human purposes: power
generation, irrigation, urban water supply,
and industrial uses. Societies are thus dealing
with a highly complex set of natural resources
that needs equally diverse approaches to their
management and conservation.
More recently, and for this reason, it has
become increasingly apparent that much of
inland fisheries management is subject to activities in economic sectors outside fisheries.
For example, the intensive dam building of
the latter half of the 20th century led to substantial modification of flow regimes and the
nature and structure of downstream lakes
and rivers. This trend has been reinforced by
increasing abstraction of water for irrigated
agriculture, which takes up to 70% of the flow
of some rivers. Low flows also exacerbate the
pollution and eutrophication of water bodies
downstream. So far, several large lakes have
disappeared due to these developments—the
Sea of Azov being one and Lake Chad another,
although in the latter case, the general drying
out of the Sahelian area may also have played
a role. Far from improving, this situation is de-
12
welcomme
teriorating further as new dams are proposed
for supposedly green power. The general impression is that each sector seeks to maximize
its own financial and social yield without considering any impacts on other users. Indeed,
it is extremely difficult for a diffuse social and
economic system such as inland fisheries to
compete financially or politically with prestigious mega-projects such as the gigantic dams
now being proposed for the Mekong, Congo,
and Amazon rivers. Furthermore, legal obligations may prohibit some sectors from maximizing their profits. Cross-sectorial planning,
whereby the yields from all users are adjusted
so as to maximize the total goods generated
by any particular system, is extremely uncommon. The difficulty of finding such papers
for submission to this conference is a case in
point.
Cross-sectorial planning implies a growing
emphasis on management of the landscape as a
whole. In the case of fisheries, this ecosystembased management has involved watershed or
basin management planning at governmental
and international levels in support of fisheries
in both tropical and temperate countries. Planning at this level often depends on efforts to
value the fisheries concerned using concepts
such as ecosystem services. It also depends
on a much more holistic understanding of
processes at basin level using the ecosystems
approach rather than the species- or habitatcentered approaches of earlier management
strategies. This involves the careful conservation of the range of habitats required for successful completion of their life histories by the
various guilds of fish inhabiting the system and
the conservation of the migratory pathways between them. This level of management is based
on the establishment of agreements on essential aspects of the aquatic environment, often
involving allocation of water between the fishery and other users of the resource. One mechanism has been the setting up of conservation
areas in some river basins to preserve essential aspects of the system, often through formal
mechanisms such as Ramsar, which recognized
fish as a conservation target in 1996. Adequate
conservation of such areas often requires rehabilitation of already damaged systems to re-
store their form and function. Methodologies
for channel and floodplain rehabilitation have
been developed and are being applied, with
particular attention being paid to alternative
structures to facilitate fish passage through
dammed rivers. Other preoccupations have
been attempts to ensure that adequate water
supplies are available for the fish assemblages
by establishing agreed-upon environmental
flows. These are aimed at protecting the aquatic environment from increasing abstractions
of water for agriculture, industry, and human
consumption, and control of flows for power
generation is coupled with a more general
concern on the impacts of dams. Research in
support of river fish conservation now concentrates on major behaviors such as migration or
larval drift, which are especially impacted by
variations in flow. While environmental flow
criteria have been developed and applied in
many smaller temperate systems, the larger
rivers of the tropics have proved more difficult.
Here, the timing and magnitude of flows is crucial to the migration and reproduction of many
species, and such events as failure to flood the
floodplain at the right time of year may result
in the loss of entire year classes of affected species. Equally important is the drive to maintain
good quality water in rivers and lakes. The
fishlessness of European rivers in the 1950s
has been corrected by concerted efforts culminating in the European Water Framework Directive. Nevertheless, water quality continues
to be poor in many other parts of the world,
and mechanisms are needed to restore chemical health to affected systems for the health of
both humans and aquatic organisms (International Decade for Action—Water for Life, www.
un.org/waterforlifedecade/quality.shtml).
Unfortunately, the past 15 years have seen
a lapse in attention to inland fisheries, particularly in the tropics, and a concentration on the
rapidly growing aquaculture sector. Isolated
centers, such as the Mekong River Commission, Lake Victoria Fisheries Organization, and
the Institutes concerned with the Brazilian
Amazon, have continued to do good work, further documenting the concepts developed in
the 1980s. More generally, the withdrawal of
funding from basic biological research in favor
inland fisheries: past, present, and future
of human resources led to the inability of many
countries to collect adequate data about their
inland fisheries. The effects of lack of funding
have accrued during a period of years, giving
uncertainty as to the actual magnitude of the
catch worldwide. Certainly, it is difficult to account for the continuing growth of inland fish
catches since 1950. Is this a true increase? Is it
based, as some would have it, on better fish statistics? Is it the result of data inflation for political reasons? Is it because of better technologies with stocking? Or is it some combination
of these reasons? Furthermore, there are many
intermediate technologies, ranging from wild
capture fisheries through stocking, removal
of predators, and fertilization of ponds to different degrees in the intensification of human
control over the production of fish that make it
very difficult to distinguish where inland capture becomes aquaculture. This continuum of
practice leads to considerable confusion statistically, and many simple stocked fisheries are
reported as aquaculture. For example, in Cuba,
the not inconsiderable stocked reservoir catch
was considered capture until a few years ago
when it was reassigned to aquaculture. However, regardless of designation, stocked fisheries
in natural water bodies are subject to the same
environmental constraints as wild fisheries.
The growth of inland fisheries is especially
difficult to explain in view of the threats from
other sectors, especially increasing demand for
water and environmental degradation. These
adverse trends are likely to get worse as human population increases further and climate
change destabilizes temperature and precipitation regimes. To some extent, negative pressures may have been counterbalanced by the
increased productivity of fish assemblages as
they are fished down. This means that there
will possibly be an increasing loss of aquatic
biodiversity as larger and more sensitive species are eliminated. There also appears to be
an ongoing trend to meet rising demand for a
limited resource by intensifying inland fisheries by stocking. This compensates for declining
production from natural fisheries and increases control over harvests but favors a relatively
narrow selection of species. Enhancement of
fisheries involves substantial changes to the
13
ownership and access patterns of previously
public resources, a sort of new enclosures.
Despite the lack of information about the cost
effectiveness of such programs, it is to be anticipated that the trend to privatize many open
fisheries will continue and even intensify in
the future. As societies become more affluent,
inland fisheries may progress from food fisheries to recreation and conservation, a trend that
will continue as long as the recreational value
outweighs the food value of catches.
It is clear that while imperfect and subject
to further clarification by more research, the
current knowledge of the biology and ecology
of inland fish and fisheries is sufficient for us
to manage fisheries in a sustainable manner
and to propose solutions to conserve fisheries in the context of other users of water. This
conference aims at focusing that knowledge to
assess the role of inland fisheries in food security, identify better methods for managing the
fisheries, and advise on better ways to integrate inland fisheries into the wider patterns
of water use in river and lake basins. Whether
resource managers will be able to apply such
knowledge to grow the fishery sector further
or indeed retain what still exists will depend
on whether or not they can deal successfully
with the challenges of increasing pressure on
aquatic systems in general. It would be sad to
have microwave ovens around the world with
no fish to cook in them. Future trends may
well depend on the development of integrated
social, political, and economic institutions as
world demand for food increases. Growth or
decline will depend on political will by such institutions to sacrifice part of their possible individual benefit for the good of the whole, not
only by the fisheries sector, but by all involved
with the use of water.

the state, quality, and management of water
resources. This multiscale approach is increasingly necessary as current management-only
approaches often do not adequately address
cross-cutting and interlinked issues. As we all
rely on the same and limited resource base, no
sector can operate rationally in isolation.
With increasing scarcity, it is key to rethink
water governance. As current water management practices often operate in an almost silolike environment, each sector manages its own
intake and outtake with little communication
with other water users. This can strain a system
that is based on the hydrologic cycle—a continuous movement of water on, above, over, and
under the surface of the planet. Withdrawals of
water from this system are through interactions
with only small parts of this cycle, in the form of
rivers, lakes, seas, oceans, or underground aquifers, but these interactions can modify the cycle.
Through structural and nonstructural semipermanent interactions with the water system, humans can change water flows through building
physical infrastructure for storage and other
flow regulation, which in turn can impact the
entire cycle and the ability of all other water users to draw on the system.
Why Water Governance?
As freshwater resources become increasingly
scarce, so does competition for them. With consumption levels at a historical high, much of
current economic development depends on reliable and safe access to water. The increasing
cost of accessing water leads to tensions among
different actors, requiring facilitated discussions between competing user groups, between
economic sectors, and even between countries
where freshwater resources span international
boundaries. It has been acknowledged by the international community that water crises are, to
a large extent, crises of governance rather than
scarcity (FAO 2014c). Without governance, it
is difficult to manage water resources, to strategize about investments in water-using sectors,
to provide and maintain infrastructure, or to
protect aquatic ecosystems adequately.
Water governance offers a framework for
addressing issues of water scarcity that goes
beyond water management. Water governance
looks at processes, actors, and institutions that
work across sectoral boundaries and with a
broad range of users of water resources and services, including agriculture, food, energy, health,
and environment. Governance encompasses the
political, administrative, financial, and social domains of freshwater use, including formal and
informal systems and mechanisms that impact
Competition between freshwater uses

remainder for municipal uses (Comprehensive Assessment of Water Management in Agriculture 2007). This distribution varies from
economy to economy and region to region. Differences can also be found between developed
and developing countries, with developed countries such as the United States showing a much
more diversified water withdrawal portfolio,
with sectors like thermoelectric withdrawing
at the highest rates, followed by irrigation (agriculture) at only 37% (Maupin et al. 2014). In
comparison, developing countries can have irrigation withdrawals as high as 90%.
Freshwater withdrawals are not the only
way humans’ impact on water resources. Freshwater systems are increasingly affected by pollution as either the pollutants are discharged
directly into water bodies or water is polluted
during use and then discharged without or insufficient treatment. Most problems related
to water quality are caused by intensive agriculture, industrial production, mining, and untreated urban runoff and wastewater (WWAP
2015). In the developing world, 90% of all
wastewater is discharged untreated into water
bodies (Corcoran et al. 2010). In industrialized
countries, industry still dumps large amounts of
pollutants and polluted waste into waters every
year (WWAP 2015).
The flow regime changes and pollution
both impact inland freshwater fisheries. Interactions with a water body influence the living organisms inside of it and this can result in
changes to the ecosystem. While occasionally
these changes can have positive effects on fish
production in certain extensive culture systems
(e.g., through nutrient enrichment), this is more
of an exception than a rule. Increased sedimentation and intensified aquatic plant growth, as
well as encroachment of agriculture into the
margins, have negative consequences on ecosystems and fish.
Effects on aquatic environments
There are two main water-related issues facing
aquatic ecosystems: (1) the health of aquatic
ecosystems, and (2) the quantity and quality of
surface and groundwater resources. Industrialization, urbanization, deforestation, mining,
and agricultural land and water use often cause
degradation of aquatic environments, which is
the greatest threat to inland fish production.
Water use in the form of withdrawals is having
serious effects on lake levels, with a number of
lakes in Asia having already reduced in size due
to abstraction of water for agriculture and other
uses. Expansion and intensification of crop production also affects inland fisheries negatively.
Excessive loadings with urban, industrial, and
agricultural wastes can have severe consequences for fisheries as lakes undergo eutrophication, increased sedimentation, and intensified
aquatic plant growth and experience encroachment of agriculture into their margins, with consequent changes in their ecosystem.
Disputes over uses of water for irrigation
and fisheries are often difficult to resolve due to
different spatial and temporal water needs. This
includes both quality and flow requirements for
sustaining aquatic habitat. Increased aquaculture production may result in increased water
use to maintain water quality.
The Need for Good Governance
Over the past two decades, the changes that impact water resources and, more broadly, natural resources have accelerated and surpassed
developments of the previous 100 years. As the
world’s population is projected to move toward
more than 9 × 109 by 2050, meeting the demand
for food is to be planned well ahead of time in a
manner that is in harmony with the ecosystems.
The changing context is not only the population
growth, which is a major driver of change for
water resources, but also the changes in consumption patterns: the number of meals eaten
per person, the content of meals, and the meal’s
manufacturing history. Processes have become
more and more dependent on the use of natural
resources, including water resources.
The Food and Agriculture Organization
of the United Nations (FAO) is going through
a strategic renewal in its policy making and
implementation to move from a focus on improving sectoral management to creating governance systems that are conducive to implementing better, more comprehensive, and more
inclusive management strategies. These new
water governance and management for sustainable development
systems will tackle the linkages, boundary conditions, and interfaces between agriculture, water, and related key sectors and elements such
as food, land, energy, natural resources, societal
goals, and major drivers of change. This will be
accomplished through addressing issues of access, rights, and tenure from the perspective
of sustainability, inclusiveness, and efficiency.
Typically, water governance in river basins is
about the efficient, sustainable, and equitable
allocation and use of water. This requires good
knowledge and understanding of the resource
and its use, the capacity to anticipate changes,
and a dialogue-based, cross-sectoral, and inclusive process to give legitimacy to management
decisions.
Examples of Food and Agriculture
Organization of the United Nations
Initiatives
Cross-sectoral dialogue in the Syr Darya
basin
The dissolution of the Soviet Union resulted
in the breakdown of the basinwide and integrated management system of the Syr Darya
River basin (and, by extension, that of the whole
Aral Sea basin) in central Asia. Prior to this, an
agreement had been reached among the riparian countries to allocate water resources to both
the upstream and downstream countries. This
provisioned that upstream countries store water to provide it to the downstream countries in
summer months for irrigation purposes. This,
however, put a limit to upstream countries to release and produce hydropower during the winter months. Downstream countries, therefore,
agreed to provide energy subsidies for their
exported oil and gas to the upstream countries
(UNECE 2015).
With the dissolution of the Soviet Union,
downstream countries chose to sell their energy
resources at full price on the international market rather than to continue subsidizing it for their
relatively energy-poor upstream neighbors. The
upstream countries responded by producing
their own energy in form of hydropower, allowing the river to flow even in the winter months.
In the end, floods and water shortages became
17
more prevalent in downstream countries. This
led to political tensions and issues that could
not be resolved by focusing on agriculture or
energy alone. The end result was a man-made
disaster in form of the shrinking of the Aral Sea
and the degradation of the basin’s ecosystems
and fish populations. As a result, fish stocks of
economic importance either completely disappeared, or declined, and in some situations have
been replaced by low-value fish. All of this has
led to very negative impacts on livelihoods and
people’s health (UNECE 2015).
In 2012, the FAO organized a series of workshops in central Asia together
with the Executive Committee of the International Fund for saving the Aral Sea
(EC-IFAS) and the United Nations Regional Centre for Preventive Diplomacy in Central Asia
(UNRCCA), using an innovative scenario-thinking approach. The goal of the workshops was to
encourage a dialogue on the future development
of the Aral Sea basin to which the Syr Darya is
one of the tributaries. The scenario-thinking approach brings together a broad range of actors
and sectors and fosters mutual understanding
among the participants.
This process continued during the transboundary nexus assessment by the United
Nations Economic Commission for Europe,
the FAO, and the Global Water Partnership,
highlighting once again that the solutions for
the water sector also lie in the energy and agriculture sector. For instance, the agricultural
sector can shift towards more water-efficient
crops (than cotton) and invest in irrigation
modernization and better land management
schemes. The energy sector, which is of strategic importance to the economic development
of countries with hydroelectric production potential, needs to take into account the associated problems with hydropower expansion for
the river basin (FAO 2014b). This, however, requires dialogue to clarify options and the roles
and responsibilities of different sectors.
Regional water scarcity initiative
The Near East and North Africa are among the
most water-scarce regions in the world. These
regions may be facing the most severe intensi-
18
unver
fication of water scarcity in history over the
coming years, with freshwater availability per
capita expected to drop by up to 50% by 2050
while populations are growing and climate
change is reducing freshwater access even
further. Competition increases with increased
scarcity, which requires facilitated debate between competitors, whether they are sectors,
different user groups, or, in some cases, countries that share the same scarce water resources. While the regional water scarcity initiative
(FAO 2014d) provides a good case study for
how difficult it can be to get different sectors
to talk to each other and to agree on a common
way forward, it also shows that there are great
benefits of going through this process as tradeoffs across sectors are identified and potential
synergies are found.
Through a joint water scarcity initiative of
FAO headquarters in Rome and the regional office in Near East and North Africa, FAO is helping the regional countries to more rationally
manage their water resources. This is being
achieved by establishing better policy formulation, cross-sectoral planning, a dialogue identifying synergies and putting these to use, and
helping them to manage tradeoffs that exist
between sectors and users.
The regional water scarcity initiative (FAO
2014d) started with a consultative process
with countries and partners to develop a regional collaborative strategy on agriculture
water management and a wide regional partnership to support its implementation. The
strategy has seven focus areas:
1.
2.
3.
4.
5.
6.
7.
Strategic planning and policies;
Strengthening/reforming governance at
all levels;
Improving water management efficiency
and productivity in major agricultural systems and in the food chain;
Managing the water supply through reuse
and recycling of unconventional waters;
Climate change adaptation;
Building sustainability, with a focus on
groundwater, pollution, and soil salinity;
and
Benchmarking, monitoring, and reporting
on water-use efficiency and productivity.
The regional water scarcity initiative (FAO
2014d) offers decision makers a platform to
discuss the interlinkages between water and
food security. This requires a clear understanding of the opportunities and trade-offs
in managing water for agricultural production—in conjunction with other sectors.
Water tenure
While competition for water and other resources is growing, mechanisms to reflect values under scarcity and enhance efficiency of
use are generally lacking. Farmers’ water use
rights are often informal and not protected by
law or registered formally. In 2012, the Committee for Food Security endorsed the Voluntary Guidelines on the Responsible Governance
of Tenure of Land, Fisheries and Forests (VGGT;
FAO 2012). These provide a set of principles
and practices that help countries establish
laws and policies that better govern land, fisheries, and forests tenure rights. At the time of
negotiating the VGGT, it was decided not to
include water, on the understanding that the
complexities of water management and the
implications for the establishment of water
tenure rights required further reflection. Water is referred to in the preface of the VGGT,
where it is acknowledged that “the responsible governance of tenure of land, fisheries and
forests is inextricably linked with access to
and management of other natural resources,
such as water and mineral resources.”
Building on these voluntary guidelines,
the concept of water tenure can be a useful
tool to extend the debate beyond water rights
and administration to understand linkages
with land tenure, resource-use efficiency, and
food security. The FAO plans to contribute to
existing guidelines and more substantially
incorporate the tenure issues into the water
governance aspect more prominently and
completely.
Irrigation governance
Worldwide, irrigated agriculture is promoted
as a means to increase production and to provide better livelihoods for farmers. For this to
happen, it is necessary to shift away from the
water governance and management for sustainable development
business-as-usual approach and towards more
forward-looking, participatory, and effective
governance of the irrigation sector. Irrigation
modernization plays a large role in promoting such a shift, adapting to changing user
demands and varying biophysical and climate
conditions.
The FAO’s work on irrigation modernization aims to support countries in increasing
water productivity in irrigated agriculture as a
central solution to the water scarcity problem.
Effective water governance requires an assessment of the costs and benefits of increasing
water productivity for farmers’ livelihoods,
food security, economic returns, and potential water savings. The FAO provides, among
other things, substantial advisory services to
the member states in irrigated agriculture and
governance of irrigation.
Most irrigation systems consist of water
storage, major and distribution canals, and
drainage canals. In particular, water storage is
and will increasingly be an important means
to enhance resilience to climate change (Turral et al. 2001). Per capita water storage capacity is still very low in many countries,
particularly in Sub-Saharan Africa. In developing countries especially, there are many
old irrigation systems that have been built for
command of very large areas and are not efficient or even operational under the changing
conditions. A lot of countries build artificial
storage through structural measures such as
dams and reservoirs, but the same objective
can also be achieved through natural storage
such as aquifers, soil moisture, and natural
wetlands, depending on the specific circumstances. There is a range of storage options
available: above and below the ground, small
and large, serving different needs and different groups of people, behaving differently under climate change scenarios, and requiring
different levels of investment and operation
and maintenance (Renault et al. 2013).
Most importantly, these water storage
options provide an opportunity for different
water users to work together. There are opportunities to work with fisheries on natural wetlands or constructed wetlands in reservoirs.
Generally, irrigation reservoirs have inherently
19
unstable water levels that interfere with the
basic biological functions of fish. There are also
risks of water pollution through agricultural
runoff. In many cases, indigenous fish stocks
have declined.
A cross-sectoral perspective on reservoirs
can help us identify management measures—
such as the construction of wetland conditions
in reservoirs—that will offer solutions for food
production, fisheries, biodiversity, and much
more. These constructed wetlands can hold
water during dry seasons, creating smaller
reservoirs that can create local fish ponds
(FAO 2000). It shows that it is possible to look
at ways of sustainable use making sure that
different interests will be met now and in the
future.
Governance of water for pollution control
and water quality management
Water quality is another global challenge
closely linked with crop and livestock production and fisheries. Water quality governance is
a complex subject, often not existing at all or
lacking in strength or fundamental requirements, making it prone to corruption. In partnerships with stakeholders, particularly United Nations Environment Programme (UNEP)
and the World Health Organization, FAO’s work
on water quality governance is focused on the
development of tools (e.g., tailored quality
standards, treatment and recycling guidelines,
environmental impact assessment, measurement, and monitoring,) and on strengthening
regulations and institutional reforms for water
quality management and pollution control.
One recent program is the governance of
water quality in terms of pollution control and
the health sector in the form of water borne
diseases. The current implementation countries have been designated as Peru and Nepal.
The program is designed to develop a multidisciplinary monitoring and reporting tool to
measure and analyze the linkage of different
water quality and food safety parameters and
the epidemiology of diseases. This is important in a country like Nepal, which suffers from
the dumping of waste in rivers, excessive use
of pesticides and agrochemicals, and water-
unver
20
borne diseases such as intestinal worms and
typhoid, and Peru, which faces major water
quality challenges from mining, agriculture,
and untreated wastewater.
The monitoring tool will look at
•
•
•
where effluents of agriculture pollution cause disease in humans—for example, through drinking water or through
accumulation in foods (e.g., heavy metals,
pesticides, and fertilizer residues);
where waterborne diseases from agricultural water use prevail; and
where polluted water is used for irrigation
to grow food.
As a result, we will be able to
•
•
•
analyze the nature of hot spots,
map the cause of the pollution and diseases outbreaks, and
make wise investment decisions and take
targeted action to mitigate and eliminate
health risk factors.
Aquaculture—A Future Challenge
Asia has the greatest freshwater aquaculture
production in relation to land area and water
surface area. In Africa and Latin America, there
is potential for growth of freshwater aquaculture production, but it is becoming more restricted due to urban development and high
competition for land and water resources. Fish
production in the coastal and offshore marine
environment offers alternative and new opportunities for aquaculture and for the supply of
world food fish when freshwater and land become scarcer (FAO 2014a).
In Conclusion: Cross-Sectoral
Governance in Practice
The FAO will continue emphasizing the importance of water for food security and nutrition, as well as the sustainable management of
natural resources for food and livelihoods in
the international water debate at all relevant
levels. This will be done through strategic partnerships with international institutions and
stakeholder groups, and by taking advantage of
prominent fora where key decisions are made
or influenced. While there is still a lot more
awareness needed for cross-sectoral work in
sustainable food and agriculture and natural
resource management, the knowledge base
is expanding with more awareness and more
demand on both sides from the civil society
as well as the involved sectors. We now know
a lot more about interactions and interlinkages, how decisions in one sector can impact
another sector or the natural resource base at
large. Analytical tools are more available now1
and we have evidence of engagement across
sectors, particularly the private sector where
cross-sectoral implications especially involving the use of natural resources are much better understood through the economic and image-related impacts Flammini et al. 2013).
But there is still a lot of work to be done in
the respective sectors. Policies to a large extent
are still formulated in a compartmental manner,
and national governments’ work in planning
and implementation is sometimes coordinated
more vertically than across sectors. Policy formulation remains fragmented and not very
conducive to cross-sectoral collaboration. While
there is a common vision and perceived need for
all parties to come together, government planning systems still remain in their sectoralized
compartments. The FAO’s new strategic framework is all about collaboration across sectors
and we certainly hope to be able to have more
concrete results of the collaboration between
water and fisheries within FAO and beyond.

Using Tribal Fishing Rights as Leverage to Restore
Salmon Populations in the Columbia River Basin

were, on average, an estimated 17 million annually (NWPPC 1986), with returns in some
years estimated to be as high as 34 million fish.
They had no way of knowing that in less than
150 years, salmon would be facing the threat
of extinction.
In their treaties, these four tribes ceded
a collective 66,591 mi2 (172,470 km2) of their
lands to the United States, agreeing to live on
reservations. The current tribal reservation
lands make up a small percentage of the tribes’
traditional homelands (Figure 1). However,
they all retained limited rights to these ceded
lands, including reserving the right to fish,
hunt, and gather at all their historical usual
and accustomed areas.
Introduction
The Columbia basin is on the West Coast of
North America, draining into the Pacific Ocean.
Approximately 85% of the basin lies within the
United States, primarily in the states of Oregon,
Washington, Idaho, and Montana, with the remainder in British Columbia, Canada. The river
system is comprised of two major rivers: the
Columbia and Snake. Columbia Lake and the
adjoining Columbia Wetlands form the headwaters of the Columbia River in British Columbia. The headwaters of the Snake River are in
Yellowstone National Park in Wyoming.
The Columbia River system is the lifeblood of all the tribes and First Nations found
along its entire length. Since time immemorial,
the water, salmon, game, roots, and berries of
our homeland—the sacred first foods—have
sustained our health, spirit, and cultures. So
fundamental was this connection that when
the Yakama, Umatilla, Warm Springs, and Nez
Perce tribes entered into treaties with the
United States in 1855, they specifically included language to ensure that they could continue
to fish, hunt, and gather their first foods. (See
the Columbia River Inter-Tribal Fish Commission’s Web site, www.critfc.org, for the full text
of each member tribe’s 1855 treaty.) They understood that the connection of their people to
these resources must be maintained if there
was any hope in preserving their unique cultures and values. When they entered into these
treaties, their primary concern was access to
these plentiful natural resources. At the time of
treaty signing, returning salmon populations
Ecosystem Impacts in the
Columbia Basin

Human impacts on the Columbia basin have
dramatically altered the entire ecosystem
since the signing of the treaties. Increased human population, dam construction, unregulated harvest, and substantial habitat modifications drastically reduced salmon populations.
Annual salmon runs today average fewer than
2 million fish—about one-tenth of what they
were, on average, historically (NWPPC 1986).
Much of this decline occurred before major
dam construction, which began in the 1930s
and continued into the 1970s.
These dams destroyed salmon spawning
grounds, created inhospitable water environments, and delayed salmon smolt out-migration. Many of these dams have fish ladders,
allowing adult salmon to swim upstream to

natural passage blockages are indicated in light gray. Areas rendered inaccessible to anadromous fish
due to human activity are indicated in dark gray.
spawning grounds, but several dams were constructed without these structures, preventing
salmon, sturgeon, and lamprey from returning
to large sections of the Columbia River basin.
(See Figure 1 for areas rendered inaccessible
to salmon due to hydropower development.)
The ecosystem is impacted by all of the
dams in the region. However, two dams in
particular dealt major blows to tribal culture.
In 1940, the reservoir that rose behind Grand
Coulee Dam flooded Kettle Falls, the site of a
major upriver tribal fishery. This scenario was
using tribal fishing rights to restore salmon populations
repeated on a grander scale in 1957 when The
Dalles Dam was completed. Four and one-half
hours after closing the floodgates on that dam,
the magnificent Celilo Falls was silenced and
what was once the largest salmon fishery in
North America was erased, taking with it the
significant tribal trading center based on a
salmon economy that had developed at this location. For many tribal elders, this loss is still
an unhealed wound to their hearts and spirits.
The tribes remain hopeful that one day these
dams will be removed and the roar of these
majestic falls will echo once more.
Exercising Tribal Fishing Rights
Tribes within the United States have a unique
relationship with the federal government.
Tribes are sovereigns and considered domestic dependent nations. Significant case law has
developed during the past century and a half.
Much of this case law was possible because the
tribes are recognized in Article 1, Section 8,
Clause 3 of the U.S. Constitution in 1789:
[T]o regulate Commerce with foreign
Nations, and among the several States,
and with the Indian Tribes.
Through a review of the negotiation notes
that lead to their treaties with the United
States, it is obvious that the U.S. negotiators
recognized the importance of salmon and first
foods to the tribes. Article 3 of the U.S. treaty
with the Yakama Nation in 1855 states
the right of taking fish at all usual and
accustomed places, in common with the
citizens of the Territory, and of erecting
temporary buildings for curing them:
together with the privilege of hunting,
gathering roots and berries. (Similar
language for treaties with Umatilla, Nez
Perce, and Warm Springs tribes.)
Through the treaties, the tribes reserved
these rights to the first foods, including salmon. These treaties remain legal contracts with
the United States and they must be honored.
Despite the treaties, the states began infringing on the tribes’ treaty fishing rights
as the salmon decline continued to worsen.
States began attempting to close tribal fish-
25
eries in the 1960s, claiming it was being done
for resource protection, even though nontribal
fishers were still allowed to fish. Frustrated
tribal fishers decided to flout state laws aimed
at preventing them from fishing, citing the fishing rights specifically reserved in their treaties
with the United States. This was a time of great
turmoil; at times, the fishers were even forced
to arm themselves for protection while fishing.
Eventually the impasse led to the tribal treaty
fishing right being challenged in federal court,
which resulted in two major court rulings. In the
United States v. Oregon (1969) ruling, the court
affirmed that the treaties entitled the Yakama,
Umatilla, Nez Perce, and Umatilla tribes to a
fair share of Columbia River fish runs. The ruling also limited the power of the state of Oregon
to regulate treaty Indian fisheries. In the United
States v. Washington (1974) case, the court ruling defined “fair share” as 50% of the harvestable surplus and reaffirmed tribal management
authority. Both of these cases were eventually
affirmed by the U.S. Supreme Court.
Formation of the Columbia River
Inter-Tribal Fish Commission
Armed with court rulings that reaffirmed
their right to fish and manage the fishery resource, the four Columbia River treaty tribes
united forces to address the significant decline
of salmon returns. Together, they formed the
Columbia River Inter-Tribal Fish Commission
(CRITFC) in 1977 to coordinate their management activities and restoration efforts. Since
then, these tribes have become leaders in accomplishing their stated goal to “put fish back
in the rivers and protect the watersheds where
fish live.” They participate in interstate agreements and international treaties controlling
salmon harvest and water management. These
tribes are also successfully rebuilding naturally spawning salmon populations, restoring
habitat, and protecting the water flowing in the
rivers. Initially focusing on salmon and steelhead, CRITFC’s efforts have since expanded to
include Pacific Lamprey Entosphenus tridentatus and White Sturgeon Acipenser transmontanus, the two other anadromous fish species
found in the Columbia basin.
26
Northwest Power Act
lumley et al.
The hydroelectric dams on the Columbia River
have one of the largest impacts on salmon and
steelhead (anadromous Rainbow Trout Oncorhynchus mykiss) in the basin. Recognizing
this, the tribes were part of the coalition that
worked to pass the Pacific Northwest Electric
Power Planning and Conservation Act in 1980.
This act addresses the impact of hydroelectric
dams on fish and wildlife. The act established
the Northwest Power and Conservation Council (two representatives from Oregon, Washington, Idaho, and Montana) and directed the
council to adopt a regional energy conservation and electric power plan and a program to
protect, mitigate, and enhance fish and wildlife
on the Columbia River and its tributaries. The
act also set forth provisions that the Bonneville
Power Administration must follow in selling
power, acquiring resources, implementing energy conservation measures, and setting rates
for the sale and disposition of electric energy.
Among other things, the act is intended to
ensure the Pacific Northwest of an adequate,
efficient, economical, and reliable power supply; provide for the participation and consultation of the Pacific Northwest states, local
governments, consumers, customers, users of
the Columbia River system (including federal
and state fish and wildlife agencies and Indian
tribes), and the public; develop regional plans
and programs related to energy conservation and renewable energy sources; facilitate
the planning of the region’s power system;
and provide improved environmental quality.
Concurrent with these actions, the act also requires planning and action to protect, mitigate,
and enhance the fish and wildlife resources of
the Columbia River and its tributaries, particularly for the anadromous fish, including their
related spawning grounds and habitat.
Wy-Kan-Ush-Mi Wa-Kish-Wit
Several salmon populations were listed as endangered or threatened under the Endangered
Species Act, beginning in the early 1990s. Due
to years of frustration at federal inaction to
develop required recovery plans to address
salmon survival at all life stages, the tribes
developed their own plan to rebuild fish populations. The plan is called Wy-Kan-Ush-Mi
Wa-Kish-Wit (Spirit of the Salmon). Wy-KanUsh-Mi Wa-Kish-Wit is a restoration plan developed through CRITFC by the four member
tribes in 1995 (CRITFC 1995; http://plan.
critfc.org/vol-1). The plan was updated in
2014 (CRITFC 2014; http://plan.critfc.org).
To date, this is the only plan that addresses
the full lifecycle of the anadromous fish species
for the entire Columbia River basin. The plan
seeks to halt the salmon decline and sets specific numeric goals for full recovery of Columbia basin salmon, steelhead, Pacific lamprey
Entosphenus tridentatus, and White Sturgeon
Acipenser transmontanus. It has a goal of doubling the 1995 salmon runs by the year 2020.
The plan provides for the full recovery of anadromous fish to the rivers and streams that
support the historical, cultural, and economic
practices of the tribes within seven human
generations. The seven-generation goal is a
common theme for tribes that guides decisionmaking processes to meet the needs of the next
seven generations of their people.
In 2012, the tribes declared that the salmon decline had been reversed. Much work remains to achieve the doubling goal, but recent
salmon returns have been as high as 2.5 million
fish, which is a significant improvement. The
goals for lamprey and sturgeon are similar: the
tribes want to halt the population declines and
restore populations to fishable populations
throughout their historical spawning range.
Using Hatcheries to Restore
Salmon Populations
The ceded lands of the CRITFC member tribes
are in the middle of the Columbia basin, beginning above Bonneville Dam. For this reason,
tribal interests are focused on fish populations
that are destined to return above that dam.
The states and federal agencies established a
substantial number of salmon hatcheries prior to 1980 to mitigate for salmon mortalities
caused by dams. Unfortunately, the states and
federal agencies focused most of that hatchery
production in the lower Columbia River below
using tribal fishing rights to restore salmon populations
Bonneville Dam, where large, nontribal recreational and commercial fisheries would benefit. As a result, the hatchery mitigation benefit accrued primarily in the nontribal fishery
and not the tribal fishery. Since the 1980s, the
tribes have sought hatchery reform practices
by moving the release locations above tribal
fishery locations to facilitate tribal harvest as
the salmon return to their natal spawning areas. Over time, the situation regarding location
of hatcheries and release of hatchery fish have
improved to better address the losses above
Bonneville Dam, but a vast inequity of hatchery
mitigation still exists.
There are two types of hatchery programs
currently in use in the Columbia basin: conventional harvest augmentation, and supplementation programs. Conventional harvest augmentation programs operate to mitigate for lost
production associated with development of the
hydropower system. Most hatcheries upstream
of Bonneville Dam continue to fulfill this role
and support the Zone 6 tribal fishery located
between Bonneville and McNary dams.
Supplementation programs are intended
to use biologically appropriate fish (e.g., fish
whose origin is from the host natal stream)
in a hatchery environment to rebuild natural
spawning populations. The reason for this approach is that abundance levels of natural populations throughout the interior basin are too
depressed to provide significant tribal harvest
and in many cases are so low that the long-term
sustainability of the populations is threatened.
Since the 1980s, the tribes have advocated for
hatchery-based supplementation programs to
help rebuild natural populations. Unlike conventional harvest augmentation hatchery programs, supplementation hatcheries use adults
captured in-river as broodstock, including a
portion that are of natural origin. Their progeny is reared in a hatchery but are released into
natural spawning areas to imprint. When they
migrate to spawn, they will return to these areas instead of the hatchery, thus supplementing the naturally spawning population. In most
cases, this does not require new hatchery construction, but reform of existing hatchery programs to provide a hatchery fish product for
a different purpose. The tribes now manage
27
or comanage, with federal and state partners,
several supplementation hatchery programs in
the interior basin.
The increasing role of tribes in hatchery
management is controversial in the Columbia
basin. Opponents challenged the scientific integrity of the tribal programs, especially as
related to the supplementation hatcheries.
The tribes met this challenge successfully.
According to a study of the Nez Perce Tribe’s
Johnson Creek Artificial Propagation Enhancement Project (Hess et al. 2012), researchers
found that with biologically appropriate fish,
hatchery-reared salmon that spawned with
wild salmon had the same reproductive success as salmon left to spawn in the wild. The
study focused on a population of summer
Chinook Salmon Oncorhynchus tshawytscha
whose natal stream is located in central Idaho, almost 700 mi (1,100 km) upstream of
the Pacific Ocean. The results of the Johnson
Creek artificial propagation study refute a
commonly held misconception and some previous research suggesting that interbreeding
of hatchery-reared fish with wild fish will always decrease productivity and fitness of the
wild populations. In fact, the Johnson Creek
research demonstrates how supplementation
programs are able to increase populations and
minimize impacts to wild fish populations. The
tribal approach to hatchery management is to
use these facilities as a tool to rebuild naturally
spawning populations: wild salmon nurseries,
as described in the supplementation recommendation of the Wy-Kan-Ush-Mi Wa-Kish-Wit
2014 update (CRITFC 2014). The tribes have
shown success in many locations in the Columbia River basin for spring and fall Chinook
Salmon, and Coho Salmon O. kisutch. Most notably, the success of fall Chinook in the Snake
River basin has brought the population from
the brink of extinction with only 78 wild fish
past Lower Granite Dam in 1990 to more than
60,000 fall Chinook in 2014, half of which were
natural-origin fish.
The tribes have shown that supplementation hatcheries can be a powerful tool for
restoring naturally spawning populations, in
particular to tributaries where the usual and
accustomed tribal fisheries are protected un-
28
lumley et al.
der the treaties of 1855. The tribes’ motivation is to restore fish populations to historical
levels, which is a benefit for all fisheries, tribal
and nontribal alike.
Water Quality and Tribal Fish
Consumption
When the tribes signed the treaties in 1855,
they never envisioned that water quality
would become so degraded, nor that consumption of contaminated fish would be an issue.
At the time of treaty signing, tribal members
drank directly from the Columbia River. Today, a host of contaminants in the river makes
this unadvisable and even dangerous. The fish,
however, do not have a choice when it comes to
the water; they must swim in the river. By doing so, the fish are exposed to and absorb these
contaminants. The state governments set fish
consumption recommendations based on the
amount of contaminants found in the fish. In
the past, these rates were based on the amount
of fish the average citizen consumes and did
not account for the higher levels consumed by
tribal members. A CRITFC study completed in
1994 concluded that tribal members consume
an average of 6–11 times more fish than the
general public. The results of a U.S. Environmental Protection Agency fish contaminant
survey, completed in cooperation with CRITFC,
showed that 92 priority pollutants were detected in resident and anadromous fish tissue
collected from 24 different tribal fishing sites
on the Columbia River (USEPA 2002). Contaminants measured in these fish included
polychlorinated biphenyls, dioxins, furans,
arsenic, mercury, and dichlorodiphenyldichloroethylene, a toxic breakdown product of the
pesticide dichlorodiphenyltrichloroethane. As
a result, the tribes raised a substantial concern
that state water quality standards were not
sufficiently protective for the tribal community
that still subsisted on large numbers of salmon
in their diet.
In 2011, Oregon adopted water quality
standards based on the tribal fish consumption rate of 175 g/d, the fish consumption
levels documented in the CRITFC survey. Currently, water quality standards for Washington
and Idaho are 6.5 g/d and tribal fish consumption rates are at the center of debates related
to revising these standards. Washington and
Idaho are in the process of revising water quality standards and hopefully will better protect
tribal consumers. In 2012, the U.S. Environmental Protection Agency disapproved Idaho’s
request to use an updated fish consumption
rate of 17.5 g/d because it was not protective
of tribal consumers. If water quality standards
for either state do not provide adequate protection for tribal subsistence populations, then
the federal government will need to step in and
promulgate water quality standards to protect
the tribal members.
When the tribes signed the treaties in 1855,
contaminated fish were not part of the deal.
Large-scale pollution is a result of both federal
and nonfederal actions. The damming of the
Columbia basin has exacerbated this problem.
Despite these concerns, tribal members continue to consume large amounts of fish for subsistence purposes. Salmon are a healthy food
source and must be protected for human consumption. In 2013, CRITFC’s chairman submitted letters to the region’s governors advocating
for stricter water quality standards based on the
higher tribal fish consumption rates. He stated,
“The tribes believe that the long-term solution
to this problem isn’t keeping people from eating
contaminated fish, it’s keeping fish from being
contaminated in the first place.”
Climate Change
Climate change impacts threaten tribal first
food resources, culture, ways of life, and treaty
rights. Considerable efforts have been made
in the Columbia basin to develop strategies
to protect and restore populations of salmon,
lamprey, and other imperiled coldwater fish,
but most of these efforts have generally not
addressed climate change. Climate change is
expected to significantly alter the ecology and
economy of the Pacific Northwest during the
21st century. Rising air temperatures are expected to decrease snowfall and increase rainfall during the winter months, leading to shifts
in the timing and quantity of runoff, including
increased flooding during the winter when wa-
using tribal fishing rights to restore salmon populations
ter is already in ample supply and decreased
flows during the summer when water demands
are high. These changes will have significant
impacts for freshwater fisheries, hydropower
production, and water supply for agriculture
and municipal uses.
The impacts from climate change will
affect salmon in a number of ways. Some examples include alteration of salmon migration patterns, degradation of salmon spawning and rearing grounds, and an increase of
predators and aquatic contaminants. If not
addressed, all of these factors could lead to
salmon extinction.
During the past 50 years, tribes have
made incredible strides in the federal courts
toward protection of environmental and cultural resources. There are more and more opportunities for the tribes to participate and
integrate traditional knowledge in regional
and international forums addressing climate
change issues.
Columbia River Treaty
The Columbia River Treaty between the United
States and Canada governs hydropower and
flood control on the 1,200-mi (1,900 km) Columbia River. The current treaty, implemented
in 1964, does not consider the needs of fish, a
healthy river, or the tribes’ treaty fishing rights
and cultural resources that are now recognized and fully protected under modern laws.
The tribes were not consulted during the initial negotiation of the Columbia River Treaty.
As a result, the treaty fails to include tribes or
tribal interests. The impacts of the Columbia
River Treaty on the tribes’ cultural and natural
resources multiplied the already disastrous effects that had resulted from the decision by the
United States to dam the Columbia River in the
1930s.
In 1944, the United States and Canada began investigations with a broad charge for a
mutually beneficial and collaborative treaty,
examining not only power generation and flood
control coordination, but also including ecosystem needs and other joint uses of the river. This
broad scope was narrowed after a major flood in
1948 that caused damage in communities along
29
the river from the mouth at Astoria, Oregon all
the way to Trail, British Columbia. The flood
completely destroyed Vanport, Oregon, the second-largest city in the state. The loss of life and
property spurred the two countries to prioritize
an international water treaty that focused solely
on coordinated hydropower and flood control
operations. The ecosystem and other interests
were relegated to each nation’s domestic processes. The treaty required the construction of
Duncan, Arrow, and Mica dams in Canada and
allowed the United States to build Libby Dam in
Montana, creating more than 20 million acrefeet (24.7 × 109 m3) of new storage. Under the
treaty, the United States paid Canada US$64.4
million to provide 8.95 million acre-feet (11 ×
109 m3) of storage in Canada for flood control
in the lower Columbia, but it is only guaranteed
through 2024. The United States returns to Canada half of the downstream power benefits the
new Canadian storage produces in the United
States. The United States purchased the first 30
years of this power, called the “Canadian Entitlement,” for $254 million. The United States began
returning the Canadian Entitlement to Canada
in 1998. This annual return of power is now valued at $250–350 million per year.
The United States and Canada negotiated
the Columbia River Treaty to last at least 60
years (2024). After that date, either party may
choose to terminate it, but they must provide
a 10-year notice of their intent to do so. That
10-year window opened in September 2014.
Seeing that date on the horizon, many tribes
in the Columbia basin started taking actions in
2007 to secure seats at the table to contribute
to analyses and participate in the decisionmaking process. These efforts have grown into
a coalition of 15 Columbia basin tribes that are
actively working with several federal agencies
and four states to reshape the Columbia River
Treaty to protect and benefit tribal culture
and resources. The coalition of 15 tribes also
coordinates with 17 First Nations in Canada
to provide information on fish passage and
ecosystem needs to inform all sovereigns and
stakeholders in the basin.
The tribes’ participation in the Columbia
River Treaty 2014–2024 review is critical for
protecting tribal rights and interests, including
lumley et al.
30
improving ecosystem functions and ensuring
favorable conditions for other tribal resources.
The tribes also seek representation on the U.S.
negotiating team if changes to the Columbia
River Treaty are discussed with Canada. The
tribes gained the agreement of the United
States to regard ecosystem function as coequal with flood control and power production during the treaty review and to include
measures to restore and preserve tribal resources and culture. Tribal interests were
included in the U.S. Entity Regional Recommendation on the Future of the Columbia River
Treaty After 2024 (U.S. Entity for the Columbia River Treaty 2013) submitted to the U.S.
Department of State in December 2013. The
U.S. Department of State retains the authority
to renegotiate international treaties but did
use the regional recommendation as a key resource during its national interests determination regarding the future of the treaty. The
regional recommendation is unique in that it
includes the broad consensus of 11 federal
agencies, four states, 15 tribes, the power sector, water users, environmental groups, and
others. The U.S. Department of State indicated
early in the review process that the ability to
reach a regional consensus would govern its
decision about whether or not to renegotiate
the Columbia River Treaty.
Flood Risks and Beneits
Historically, salmon smolts traveled to the
ocean during the freshet that occurred as the
winter snowpack melted. This natural pattern
was dramatically changed by the implementation of the Columbia River Treaty, with its
specific goal of reducing the size of this annual
event. The dams and careful reservoir control
called for in the treaty reduced the annual
freshet from an average of about 500,000 ft3/s
(14,160 m3/s) to an average of about 275,000
ft3/s (7,790 m3/s). The operation of the treaty
dams shifted much of the river’s flow to occur
during the fall and winter months for downstream power generation benefits, a time
when salmon smolts were not able to take advantage of it. The treaty and the dams it authorized have changed the entire ecosystem and
eliminated all the benefits that river flooding
provide.
Floods are a natural and beneficial characteristic of river systems. Flooding is viewed
negatively because people have moved into
the floodplain, thus putting themselves into
harm’s way. As dams lowered the likelihood of
major flooding, more and more people moved
into the historical floodplain. This, in turn, increased the demand for even stricter water
control to protect floodplain property. However, even with all of the reservoir storage capacity in the Columbia basin, it is still impossible
to perfectly control flooding in the floodplain.
Additionally, this demand for perfectly predictable and constant river flows is in opposition
to the ecosystem’s need for flooding. The Columbia basin tribes do not believe this is an
either/or situation and are confident that the
needs of major flood prevention can be balanced with the seasonal increases in flows required by salmon and for ecosystem functions.
A public discussion is needed to discuss how
best to modernize our approach to regional
flood-risk management. Regardless of whether
or not the Columbia River Treaty is renegotiated, a public review of flood-risk management
is required because the Columbia River Treaty
does not go away in 2024. Without intervention to modernize the treaty, the flood-control
provisions become automatically worse in the
United States, putting extreme operational
demands on U.S. facilities and increasing the
burden on the tribes’ resources and healthy
ecosystem function. With climate change also
a significant consideration, the United States
has strong motivation to modernize flood-risk
management.
A primary objective of the Columbia River
Treaty is to keep Portland from being flooded.
Ironically, the United States and Canada agreed
to accomplish this objective under the treaty by
flooding vast sections of the Columbia basin in
Canada. Lands that were never underwater are
now flooded by reservoirs for a substantial portion of every year, with some becoming mud
flats and then dust bowls as the water is drawn
down for power generation. These dams and
many other dams in the Columbia basin accomplished flood control by creating permanent
using tribal fishing rights to restore salmon populations
floods behind these dams, which destroyed
towns, economies, indigenous communities,
and the ecosystem. It is important to note that
progress came at a great cost, and mitigation for
these costs has not come close to the sacrifices
of the region. Now is the time to begin a discussion about whether these were good decisions
and whether these actions can be reversed. The
review of the Columbia River Treaty has provided a backdrop for these discussions.
Restoring Fish Passage to
Historic Locations
Since the late 1800s, governments and private
interests in the United States and Canada have
constructed more than 1,000 dams in the more
than 160,000 mi2 (414,400 km2) of the Columbia basin that were historically accessible to
anadromous fish. Many Columbia basin dams
completely block fish passage into the watershed’s upper reaches. Dams obstruct passage
of salmon and other anadromous fish between
spawning and rearing habitat and the Pacific
Ocean. Where fish passage was not provided,
extirpation of the upstream population was
the result. Dams and other water resource developments made more than 55%, or nearly
100,000 mi2 (259,000 km2), of the historical
spawning and rearing habitat inaccessible to
salmon, lamprey, and sturgeon.
Extensive work throughout tributary watersheds has restored passage to more than
15,000 mi2 (38,850 km2) of this habitat. The
remainder, about 80,000 mi2 (207,200 km2),
is still blocked. The largest blockages occur in
the upper Columbia River at Chief Joseph and
Grand Coulee dams and in the Snake River at
the Hells Canyon Complex. Construction of
Grand Coulee Dam eliminated approximately
1,100 mi (1,770 km) of spawning habitat and
extirpated the largest number of known anadromous populations relative to other projects.
On the Snake River, the construction of the
three-dam Hells Canyon Complex in the 1950s
and 1960s blocked nearly 2,000 mi (3,200 km)
of anadromous fish habitat. Additional spawning habitat was lost following construction of
other main-stem and tributary dams. In total,
31
more than 30% of the habitat originally available to salmon in the Snake River basin has
been lost. The extent of fishing by native peoples also measures the magnitude of damage.
Above the four lower Snake River dams, for
example, tribal fishers are presently harvesting salmon at less than 1% of precontact levels
while Pacific Lamprey are not harvested due to
extremely low adult returns.
Downstream of the Chief Joseph, Grand
Coulee, and Hells Canyon Complex dams, other
dams block salmon and lamprey habitat in virtually all the tributaries. Small hydroelectric
dams and irrigation diversion dams dot the
landscape, excluding or impeding passage to
spawning and rearing habitat above. Forestry
practices and poorly designed roads and culverts create additional blockages to an undeterminable number of tributary streams and
habitat miles.
Initiated in large part by the Columbia
River Treaty review process, the Columbia
basin tribes and First Nations cohosted both
a technical workshop and a major conference
on restoring fish passage in 2014. Based upon
the information shared during the technical workshop and the Future of Our Salmon
Conference, it is clear that fish passage can
be restored above the Chief Joseph and Grand
Coulee dams and into the spawning grounds
in Canada. With these findings, the Columbia
basin tribes and First Nations released a joint
report on restoring historical fish passage in
January 2015.
Many tribes and First Nations have been
without salmon for decades—a major blow to
their cultures and relationship with the Creator. Now is the time to right this wrong and
restore fish passage to historical locations.
Tribal Communities Displaced by
Dam Construction
The U.S. Army Corps of Engineers (USACE)
built four dams on the main-stem Columbia
River that inundated the four treaty tribes’
usual and accustomed fishing places and fishing villages along that stretch of river. This inundation also impacted nontribal communities
located along the river. To mitigate for the im-
32
lumley et al.
pact on tribal communities, Congress designated federal lands as mitigation in the River and
Harbor Act of 1945 (Public Law 79-14) and, in
1988, directed the USACE to acquire private
lands and construct the needed infrastructure
for this purpose in Title IV of the Southern California Indian Land Transfer Act (Public Law
100-581).
Most of the nontribal communities affected by the inundation have received compensation or relocation assistance. Indeed,
many nontribal communities were relocated
with federal funding and support almost immediately after the dams were constructed.
The most recent nontribal community to be
relocated was North Bonneville, which was relocated in 1978 due to the construction of the
second powerhouse at Bonneville Dam.
Most of the tribal community along the
Columbia River, however, is still waiting for
relocation assistance since the USACE constructed Bonneville Dam in 1938, The Dalles
Dam in 1957, and John Day Dam in 1971. Between 1996 and 2011, the USACE purchased
private land for tribal use to provide tribal
fishers access to their usual and accustomed
fishing areas. The USACE constructed infrastructure at these sites for camping, fishing
access, and ancillary fishing facilities. The
federal government still has an outstanding
and ongoing obligation to analyze and undertake remediation and mitigation projects for
loss of tribal homes and access to usual and
accustomed lands. This obligation includes
infrastructure development for the cultural,
social, environmental, religious, and traditional practices lost to the tribes because of
federal hydroelectric development of the
river. Federal development of the Columbia
River hydropower system has resulted in persistent poverty and unhealthy and unsafe living conditions for tribal members living along
the river. Currently, the most urgent need is
for housing and supporting infrastructure.
The unfair treatment of the tribal community
has garnered the attention of numerous news
outlets in recent years. The U.S. Congress
needs to authorize and appropriate adequate
resources to the USACE to complete the relocation assistance. This has yet to occur.
River Damming on a Global Scale
On a global scale, clearly there is no relief beyond Earth. The large-scale damming of rivers around the planet has and will continue to
cause great harm to the earth’s ecosystem. This,
in turn, will damage food sources in the ocean
and in our rivers, damage local economies, and
cause substantial impacts to indigenous communities that may not enjoy the same legal protections that nonindigenous communities enjoy.
There is still much to learn about the global relationship of inland waters and the ocean. What is
known, however, is that there will be considerable damage from major dam building that will
have irreversible effects.
Conclusions
The U.S. Constitution protects tribal rights. The
tribes’ treaties with the United States have not
only protected the tribal fishing rights, they
have provided crucial legal leverage that is
helping drive current salmon recovery efforts.
As such, tribal litigation was a powerful tool to
address the needs of salmon and tribal fisheries. Litigation will continue to be a powerful
tool. However, public and private partnerships
are often stronger than litigation when used to
achieve successful salmon rebuilding programs
and meet other public policy objectives.
Despite many daunting challenges, the
tribes never strayed from their mission to protect salmon. Remarkably, the salmon decline
has been reversed. The tribal work has only begun, but the success of tribal efforts will benefit
future generations, tribal and nontribal alike.
Tribal ecological knowledge has guided
the development of the member tribes’ and
CRITFC’s science programs. A key element of
this traditional wisdom is the view that people
are a part of the ecosystem (e.g., deep tribal
connection to first foods). Changes to the ecosystem also affect humans. People are not outside of the ecosystem, nor does the ecosystem
exist solely for human use. Humans would all
be better off if they viewed themselves as a
part of the ecosystem. If more people realized
this, there would be much better decisions
where the environment is concerned.
using tribal fishing rights to restore salmon populations
Ecosystem-based governance is key to our
success as Earth’s inhabitants, including contributions by indigenous communities to the
decision-making process. We owe this to our
future generations.

Freshwater Fish in the Food Basket in Developing
Countries: A Key to Alleviate Undernutrition
nanna roos*
Department of Nutrition, Exercise and Sports, University of Copenhagen
Rolighedsvej 26, Frederiksberg 1958, Denmark
Growth in infants and young children is
assessed by comparing the individual’s growth
with growth standard curves for healthy children. Poor nutrition in early life can either occur as acute energy deficiency leading to low
weight (wasting) and/or chronic deficiency of
nutrients and energy over a long time leading
to chronic undernutrition manifested as stunting (shortness). While wasting is immediately
life-threatening, shortness may not appear
critical. However, stunting is documented to
be associated with many health implications,
including impaired physical and cognitive development (Victora et al. 2008) and increased
risk of mortality (Black et al. 2013). Out of the
more than 6 million children who die annually
before the age of 5 years, the death of 3 million
(44%) children are related to undernutrition,
and of these, 1 million children die from complications that are linked to the fact that they
were stunted as a result of poor nutrition and
living conditions throughout their short lives
(Black et al. 2013).
Although there is some encouraging
progress in reducing global undernutrition,
including stunting, the number of stunted
children was 165 million in 2011 (Black et
al. 2013), an unacceptable level. The present
rate of reduction is far too slow to eliminate
stunting as a public health problem within a
reasonable time. With the present progress in
improving nutrition, the number of stunted
children in 2025 is predicted to remain high,
estimated to 127 million (IFPRI 2014). Targeted efforts to improving access to nutritious
foods and diets during the 1,000-d period are
crucial to reduce undernutrition in food-insecure populations.
The Challenge: The
One-Thousand-Day Window of
Opportunity to Improve Nutrition
How can freshwater fish contribute to improved
diets and nutrition in food insecure populations with people who are either undernourished or at risk of becoming undernourished?
With a focus on the nutritional problems typically affecting food-insecure populations, there
may be ways to increase the contribution from
freshwater fish resources to alleviate these nutritional problems for better health. Linking
primary food production—mainly focusing on
agriculture but equally relevant for fisheries—
to the nutritional problems in food insecure
populations is being investigated within the
framework of nutrition-sensitive agriculture
(Jaenicke and Virchow 2013). Food systems
are being investigated for possible ways to be
reshaped in order to narrow the gap between
the food supplied and the required nutrients
needed for a more balanced diet in vulnerable
populations (Pandya-Lorch and Fan 2014).
What are the global nutritional problems
of concern? Good nutrition is needed for all
throughout life, but the consequences of poor
nutrition is particularly critical in early life
during the 1,000-d period from conception
through pregnancy and the first 2 years of a
child’s life (Bogard et al. 2015). Infants and
young children are also particularly vulnerable to not being able to fulfil their nutritional
requirements due to the relatively high physiological demands for energy and nutrients for
rapid growth and development and limited
stomach capacity.

The Role of Fish in the
Food Basket
roos
Fish is a nutritious food source that adds highquality protein, fat with beneficial fatty acids,
bioavailable vitamins, and minerals, as well
as diversity and palatability, to the diet. Deficiencies of specific nutrients such as vitamin
A, iron, zinc, and iodine are well-documented
public health problems in food-insecure populations (Black et al. 2013; IFPRI 2014), and the
importance of a diverse diet with contributions
of animal-source foods (fish, meat, milk, and
eggs) for prevention of undernutrition is also
evident (Arimond and Ruel 2004; Allen 2012).
Fish in the diet can contribute to diversity and
most of the nutrients commonly scarce or deficient in diets.
What role does freshwater fish play
in populations now affected by undernutrition, and how can freshwater fisheries resources contribute to speeding up
global progress in alleviating undernutrition?
The role of fish and seafood, including freshwater fish, was reviewed for any indications
of whether countries with high availability of
fish were less affected by stunting in children.
Seafood supply data at the national level were
extracted from Food and Agriculture Organization of the United Nations (FAO) statistical databases (FAO 2014) for selected countries with
a range of high to low supplies of fish (3–65 g
fish/person/d), and also having a gradient of
prevalence of child stunting (10–41% of children <5 years of age stunted; Table 1; FAO
2014; WHO 2015). There are no indications
that a higher average per capita fish supply at
the national level prevents stunting in children.
This does not support a conclusion that fish is
not important for nutrition in these countries,
but indicates that securing a high fish supply
at the national level does not necessarily lead
to better nutrition. The relative contribution of
fish to diets is not reflected in the fish supply
data. The importance of fish relative to other
foods varies between countries. For example,
in Bangladesh, more than half of the dietary
animal protein available for the population
comes from freshwater fish. This share of protein supplied from freshwater fish is higher
than in any other country. The nutritional situation in Bangladesh is poor and more than
40% of children are stunted, caused by other
dietary factors than fish intake as well as nondietary factors such as poor water, sanitation,
and hygiene.
National supply data for average per
capita availability of freshwater fish covers
large variations in consumption of fish between socioeconomic, ethnic, and age population groups. Dietary surveys in food-insecure
populations with access to freshwater fish
resources show that fish is often consumed
daily or several times per week, even in poor

freshwater fish in the food basket in developing countries
households (Roos et al. 2003). However, even
though fish is consumed very frequently, the
portion sizes can be too small to have nutritional significance. For example, in Cambodia, children’s diets contained portion sizes
of fish as low as 3 g, just a teaspoon (Skau et
al. 2014). If a meal contains only few grams of
fish—for example, dried fish added to a mixed
dish to add flavor—or a few small-sized fish
are shared among many family members, the
nutritional contribution is not sufficient to
have an impact on health.
Inland Fisheries Can Contribute
to Improve Dietary Quality and
Improve Nutrition
Freshwater fish is a highly nutritious food
source and has the potential to contribute
much more to reducing the problems of chronic undernutrition and stunting. What actions
can release this potential and transfer into improved nutrition?
The International Food Policy Research
Institute (IFPRI) analyzed scenarios for the
impact of investing in health and nutrition
interventions for reduction of stunting to either 15% or less than 10% among children
less than 5 years of age in 116 developing
countries by 2015 (IFPRI 2014). The analyzes
showed that along with basic health interventions such as improving access to safe water
and sanitation, a key to reducing stunting is
to improve the quality of the diet through a
higher intake of nonstaple foods (Table 2). As
stunting in children is the result of poor livelihoods, including poor diets, access to clean
37
water and basic sanitation, as well as girls’
schooling, are needed to reduce the risk of
stunting. The IFPRI scenario analyzes showed
that to achieve a reduction of stunting to less
than 10% in 2025, 98% of all households
need to have access to clean water and schooling for girls, and access to improved sanitation, mainly toilets, also needs to be drastically improved and be available in 9 out of 10
households. Diets also need to be improved to
achieve a significant reduction in child stunting. Total food intake (dietary energy) needs
to increase by around 10%, from an average
of 2,686 kcal/person/d to around 2,900 kcal/
person/d. However, this increase in average
dietary energy intake should mainly be contributed by nutritious nonstaple foods, not
from more carbohydrate from rice, wheat, or
maize. A contribution of 54% of energy from
nutritious nonstaple foods is necessary in order to reach the more ambitious scenario of
reducing stunting to less than 10%. Having
more fish in the diet is an important contribution to nutritious nonstaple foods and improved dietary quality.
Targeted actions through programs and
policies should support freshwater fish resources playing a larger role in improving diets of women and young children and thereby
reducing stunting, which can have a positive
impact on reducing child mortality.
Nutritional Quality of Fish
Fish provides high-quality protein and important fatty acids, vitamins, and minerals.

as aquatic organisms are good sources of essential n-3 and n-6 fatty acids and also provide the valuable long-chain polyunsaturated
fatty acids (LCPUFA) docosahexaenoic acid
(22:6n-3), and eicosapentaenoic acid (20:5n3). Growth retardation is one of many physiological consequences of deficient intakes of
n-3 and n-6 fatty acids and one factor in the
complexity of stunting. Long-chain polyunsaturated fatty acids are specifically important
for brain development and thereby cognitive performance (Lauritzen et al. 2001). All
fish contain essential fatty acids, but not all
fish species are equally good sources of n-3
fatty acids and LCPUFAs. Coldwater fish species tend to have a higher content of LCPUFAs
compared to the warmwater fish (Michaelsen
et al. 2011).
The recommended intake of the essential n-3 fatty acid (linolenic acid, 18:3 n-3) in
young children is 0.4–0.6% of the dietary energy (%E), and 4–6%E for essential n-6 fatty
acid (linoleic acid, 18:2 n-6) (Michaelsen et al.
2011). There are little data available on actual
intakes of essential fatty acids in populations.
In Figure 1, the %E supplies of n-3 (A) and
n-6 (B) from foods in 10 selected countries
are shown as function of the economic status
of the countries expressed as gross domestic
product. The countries represent a wealth
gradient from low- to middle-income countries. Data are extracted from FAO’s statistical
database (FAO 2014). The ranges for the recommended intakes of n-3 and n-6 fatty acids
in children are marked in Figure 1 to indicate
whether the countries may be at risk of having
deficient supplies of n-3 and n-6 fatty acids.
People in the poorest countries are particularly at risk of being deficient in essential fatty
acids. Bangladesh has the lowest n-6 supply
among the selected countries due to a very
low total fat supply. However, the n-3 supply
in Bangladesh is less critical and above other
poor countries because of the relatively good
supply of fish. While n-6 fatty acids are often supplied by plant sources, animal-source
foods, particularly fish, are important—but
not the only—contributors of n-3 fatty acid.
The food supply data originating from the FAO
statistical database is associated with uncertainties, but do provide an important indication that the supply of essential n-3 fatty acids
are likely to be critically low in many populations. Children and women are particularly
vulnerable and, therefore, benefit most from
consumption of fish, including from freshwater sources (Michaelsen et al. 2011).
In addition to protein and fat, fish also
supplies vitamins and minerals. There is considerable variation in the contents of different

countries with variable economic situation (gross domestic product). The range for recommended

freshwater fish in the food basket in developing countries
vitamins and minerals among species, and
an important factor is which parts of the fish
are actually eaten. Cultural perceptions and
individual preferences are determinants for
which parts of a fish, for example the head, are
considered edible. Studies in Bangladesh and
Cambodia showed a large variation in vitamin
A content among small indigenous fish species (Roos et al. 2002, 2007a), with a single
species, Mola Amblypharyngodon mola having levels 100 times higher than other species
from the same freshwater environment. Almost all the vitamin A in Mola is located in the
eyes or the viscera —specifically the liver—of
the fish. Therefore, an important determinant
for the dietary value of Mola is whether the
head, as well as the viscera, are considered
to be edible (Roos et al. 2002). Compared to
large fish species, for example carp produced
in aquaculture and for which only the fillets
were eaten, the small indigenous fish species,
which were eaten whole, were a very important source of vitamin A.
Small fish were also an important source
of calcium because unlike the larger fish, the
bones of most of the small fish species were
eaten. Based on a household study in Bangladesh and the analyzed contents of calcium in
whole, raw fish, Roos et al. (2003) developed a
correction factor to estimate the content of calcium in the edible parts of different fish species
based on whether the bones were consumed
or not. For large fish, the bones were reported
never to be eaten and, therefore, the dietary
contribution from these fish species would
be insignificant. The small fish with soft thin
bones such as Mola and Chanda Parambassis
baculis, on the other hand, were an excellent
source of calcium because more than 90% of
the bones were eaten. For other species, the
contribution to calcium intake was reduced,
though still valuable, because the bones were
only partially consumed. Small fish species in
general have higher contents of iron and zinc
than large fish species (Roos et al. 2007b). In
Bangladesh, small fish species are among the
most important sources of essential vitamins
and minerals in many poor households, although the quantity of consumption is too low
to avoid deficiencies.
39
How Can the Consumption of Fish
by Women and Children Increase?
Availability and accessibility of fish to poor
households are important to secure higher intakes. However, access alone is not enough to
secure intake in women and young children,
especially during the critical 1,000 d. There are
economic and other barriers to fish consumption, even when available from capture or local markets, for example, cultural beliefs about
when to introduce fish in children’s diet and
a mother’s fear of bones getting stuck in the
throat of the child (Skau et al. 2014). A general
constraint to feeding of infants and young children is that caregivers lack time to prepare nutritious complementary foods during the critical transition from breastfeeding to semisolid
foods at 6 months of age, when special baby
foods are needed (FAO 2015).
One approach to change dietary habits and
promote higher consumption of fish is through
nutrition education, for example, training, information campaigns, and cooking demonstrations. Dissemination of dietary guidelines to
the population or specific populations groups
is used, for example, in most western countries. Dietary guidelines include recommendations about frequency (eat fish twice a week)
and/or quantity (eat 200 g fish per week) of
fish consumption. Some countries also have
recommendations for limiting the intake of fatty, predatory fish species such as tuna during
pregnancy because of the risk of exposure to
environmental toxins. Nutritional campaigns
have variable impact on actual behavior and
have the largest impact in privileged populations groups, whereas households with fewer
resources are harder to reach, due to lack of
schooling, poor health, and often stressful
living conditions, which makes adoption of
dietary advice difficult. Nutrition education
programs in combination with other interventions, such as extension of agricultural practices, have been investigated and evaluated
for impact on nutritional status in developing
countries (Berti et al. 2004; Kerr et al. 2011).
Overall, nutrition education can change dietary
habits in some populations, but the chances for
success are highest when combined with food
40
roos
production interventions that can make the
recommended nutritious food more available,
and thereby the adoption of dietary recommendations easier.
In view of the modest success of substantially reducing undernutrition with present
efforts, the need for more targeted interventions to increase intake of nutritious foods has
emerged. Stunting can begin early. Therefore,
it is critical to provide sufficient nutrition to
women and children during the 1,000 d. Consequently, increased focus is on the potential
of providing nutritious food supplements to be
distributed in targeted programs or through,
for example, social marketing to reach women
and children when they are most at risk of being undernourished (de Pee and Bloem 2009).
Food aid products developed for children usually contain milk powder to improve nutritional quality. However, fish can nutritionally substitute milk, and research has been initiated to
develop processed food aid products based on
fish instead of milk. Such products can be produced locally in the countries or regions where
fish are abundant (Kuong et al. 2013; Skau et
al. 2015).
Food aid products for food distribution in
food insecure populations are widely used by
the World Food Programme (WFP), the United
Nations Children’s Emergency Fund (UNICEF),
and many other organizations. There are basically two types of foods, fortified blended foods
(FBF) and lipid-based pastes, also known as
ready-to-use-therapeutic foods (RUTF) (de Pee
and Bloem 2009). Multiple studies over the past
20 years have shown that RUTFs are very efficient in treating severe malnutrition (Briend
et al. 2015) while FBF products can be used to
prevent vulnerable children from becoming severely malnourished. A key goal is to develop
the best products at the lowest price, preferably with local food ingredients to meet cultural
preferences, as well as to create jobs and benefit
local economies (Bogard et al. 2015). At present, most products used by WFP, UNICEF, and
national governments are produced and distributed by few global manufactures.
In the search for the optimal composition
of FBF and RUTF food supplements for infants
and young children, adding a proportion of
milk powder to plant-based products has a
positive impact on child growth (Michaelsen
et al. 2009). However, milk is expensive and as
the use of supplementary food products is projected to expand, reliance on a single food item
with a high and fluctuating price is a severe
limitation. Therefore, the possibility for using
fish as a nutritionally suitable alternative to
milk in such products, while, at the same time,
being acceptable for consumption, is now being investigated.
In Cambodia, the nutritional impact of
using small, indigenous fish in a rice-based,
processed porridge (instant baby food) was
investigated in the WinFood project (Skau et
al. 2015). Two local, fish-based products were
developed compared to two standard products
used by WFP in food aid programs, of which
one WFP product contained milk powder. One
WinFood product was made with two fish species (Mekong Flying Barb Esomus longimanus and Paralaubuca typus; total 12% of dry
weight) specifically selected for high contents
of micronutrients. In addition, a small amount
(2% of dry weight) of an edible spider commonly consumed in Cambodia and found to
have high zinc content was added to this WinFood product. The other WinFood product was
made with mixed small fish species selected
for high local availability and low price. This
product was added to a mix of micronutrient
fortificant similar to the micronutrients added
to WFP standard products.
The foods were tested in a randomized trial in infants who were fed the foods every day
for 9 months. The WFP product with milk powder and the WinFood product containing small
powdered fish and extra micronutrients were
able to prevent the onset of stunting during the
first 6 months of the study. The study showed
that length growth in children was supported
equally well by the fish and milk powder products (Skau et al. 2014, 2015). The food supplements were not able to completely prevent
children from being undernourished; however,
the nutritional status of these children was
better than the overall national level. The food
products only provided a proportion of the diet
to the children who were also getting breastmilk and other foods. The complete diet was
freshwater fish in the food basket in developing countries
analyzed using linear programming to evaluate whether it could meet the nutrition requirements of the children (Skau et al. 2014).
The linear programming modelling indicated
that even a daily nutritious food supplement
like the WinFood products was not sufficient
to fully compensate for the general poor diet,
but in combination with general nutrition
education, the provision of processed foods
with fish and additional micronutrients can
make a significant contribution to improve
poor nutrition in infants and young children.
Small powdered fish were found to be an affordable alternative to milk powder, which is
promising for the future use of small freshwater fish in the production of local food supplements. This is highly relevant in Cambodia
where milk is expensive and consumption is
low while freshwater fish is seasonally available and an appreciated food, but the quantity
of fish consumed in the daily diet is too low to
prevent undernutrition.
Based on the WinFood results and the
collaboration established between nutrition
research at the University of Copenhagen, the
fisheries research team in Cambodia at The Department of Fisheries Post-Harvest Technologies and Quality Control, and the Institute de
Recherché pour le Développment, Montpellier,
France, a new lipid-based product with small
fish is now being developed for testing in treatment of severely undernourished children
(Sigh 2016).
Also, in Bangladesh, the production of processed products with small fish for improved
nutrition during the 1,000 d has being investigated (Bogard et al. 2015). WorldFish in
Dhaka has developed a processed fish product
for children with 15% small fish (dry weight)
and a fish chutney supplement for pregnant
and lactating women with 37% small fish (final product). These products are well accepted and can be produced locally, making small
freshwater fish, often traded at a low price in
peak season, into a high-quality product that
can support a consistent higher intake of fish
during the 1,000 d. The aim of making these
products available is to increase the amount
of fish consumed in the target groups of pregnant and lactating women and young children,
41
in a population with a habit of frequent consumption of fish but in far too small quantity
to significantly impact health and reduce risk
of stunting.
Freshwater Fish in the Food
Basket in the Future
The examples of processing small freshwater
fish into quality products presented here are
only one approach to enhancing fish consumption. There are other opportunities to be explored so that more of the fish available from
freshwater resources can be channeled into
the diets of the nutritionally most vulnerable,
thereby improving diets and reducing stunting.
The approaches to improving the contribution
from freshwater fish to better nutrition should
be explored jointly by the inland fisheries sector and the nutrition sector. The opportunities
to be considered include
•
•
•
•
Utilization: Most inland fish (>90%) landed already goes to human consumption
(Welcomme et al. 2010), and unlike marine catches, there is little room for increasing the amount for human consumption. However, on a local basis, there can
be ways to ensure better utilization, for example, reducing postharvest losses, especially of small fish.
Availability: Improved management of
inland fisheries may improve availability of
freshwater fish for food-insecure populations. Small fish are nutritionally advantageous compared to large fish, and management targeting availability of small-sized
fish can improve the nutritional contribution from freshwater fish in the food basket.
Consumption: Consumption of fish can be
low even when fish supply is available. Nutrition education could be integrated into
fisheries programs, targeting food-insecure populations to raise awareness of the
importance of fish for women in the reproductive age and children.
Linking nutrition and fisheries in the value
chain from catch to consumption: Collaboration between inland fisheries and
nutrition sectors can be strengthened to
42
roos
ensure fish availability and consumption
for all, but in particular during the 1,000-d
window of opportunity to prevent chronic
undernutrition. Through partnerships
between the fisheries and nutrition sectors
throughout the value chain, freshwater
fish can be made available for increased
consumption, fresh or in processed products, with the aim of increasing the amount
of fish consumed. Thus, the benefit of the
highly nutritional qualities of fish can be
enhanced and contribute to alleviating undernutrition.

Abstract.—The assessment process is fundamental to ensuring that inland fisheries are managed sustainably and valued appropriately so that they can support livelihoods, contribute to food security, and generate other ecosystem services. To that end,
a global group of leaders in inland fishery assessment convened to generate a list of
recommendations and specific actions for improving assessment of inland fisheries.
Recommendations included the needs to assess the global contribution of inland fisheries to food security, develop and implement rigorous approaches to evaluate various
inland fishery management actions, develop and implement creative approaches to
improve the assessment of illegal fishing activities, and improve statistical data for
unreported and unregulated catches in inland waters. The group also identified a need
to develop standardized and defensible methods of biological assessment of inland
fish and fisheries that include data collection, database management, and data sharing and reporting to reflect diverse ecosystem types. Moreover, it was recommended
that assessment be designed to better inform inland fishery management and other
sector planning and decision making at the appropriate scales (e.g., integrated water resource management) through stakeholder engagement, valuation of fisheries
outputs, and identification of policy alternatives with consideration of trade-offs. The
inherent diversity of inland fisheries in terms of ecological, socioeconomic, and governance attributes was recognized throughout the process of developing the suggested
actions, including how such attributes combine to provide fisheries-specific contexts
for management. Using appropriate and accessible communication channels is critical to more effectively package, present, and transfer information that raises awareness about inland fisheries values and issues; alter human behavior; and influence
relevant policy and management actions. Creating mechanisms to facilitate dialogue
among the diverse range of stakeholders is equally important. Improved assessment
techniques should play a fundamental role in supporting sustainable inland fisheries
management and contributing to food security and livelihoods, while also maintaining
or improving ecological integrity.
Introduction
Inland fisheries are diverse, spanning a range
of sectors (e.g., commercial, recreational, and
subsistence) and occurring in very different
ecosystems around the globe (e.g., through
the ice of frozen lakes in Scandinavia to small
forest streams in the United States and the
vast floodplain systems of the Mekong basin;
Welcomme 2011). Although often cast in the
shadow of global marine fisheries, inland fisheries are increasingly recognized for their contributions to food security, livelihoods, human
well-being, and the economies of many coun-
assessment of inland fisheries
tries (Lynch et al. 2016). The United Nations
Food and Agricultural Organization (FAO) fishery statistics estimate that 10 million metric
tons of freshwater fish are harvested per year,
although it is acknowledged that the actual
harvest is probably much greater due to unreported and unregulated fisheries (Welcomme
et al. 2010). In addition, billions of individual
fish are captured and released by anglers in the
recreational sector (Cooke and Cowx 2004).
Ensuring that inland fisheries are managed
to provide ecosystem services that benefit
humans while also maintaining biodiversity
and ecosystem integrity is crucial, particularly
given the many external influences (e.g., hydropower development, irrigation, pollution,
and climate change) that impact both aquatic
ecosystems (Dudgeon et al. 2006; Vörösmarty
et al. 2010) and the fisheries that they support
(Welcomme et al. 2010; Beard et al. 2011).
Fishery planning needs to be well informed
about all aspects of the resource: the status of
fish populations; the nature of existing fisheries; and the social, environmental, and economic issues that shape resource use (McCafferty et al. 2012). This planning should also be
integrated with planning for other, sometimes
competing, aquatic ecosystem services (e.g.,
irrigation, hydropower, and drinking water).
Traditionally, fishery management focused primarily on fishing activity and the target populations, but it is now widely recognized that
because fisheries and other uses of aquatic resources have direct impacts on the ecosystem,
all users need to be managed in an ecosystem
context (Beard et al. 2011). Ecosystem management has been defined as “the application
of ecological, economic, and social information,
options and constraints to achieve desired social benefits within a defined geographic area
and over a specified period” (Lackey 1999).
This definition implies that the management
of different resource uses should be interconnected rather than separate processes that
have potentially conflicting objectives and
overlapping data needs and require a common
decision framework. As such, ecosystem management is “a management philosophy that
focuses on desired states rather than system
outputs” (Cortner and Moote 1994). This focus
47
on desired states offers a foundation for comparing impacts and, therefore, net benefits of
different uses of aquatic resources.
Fishery assessment is fundamental to effective planning and management. Assessment
activities in the fishery management cycle are
focused on three key questions. Fishery potential—how big could the fishery be? Fishery use—how big is the fishery currently?
Fishery impacts—how is the fishery impacting the target populations and the supporting
ecosystem? In some jurisdictions, assessment
techniques are well developed, with extensive
capacity to undertake biological assessment,
synthesize data, and use them to inform the
fishery management cycle, not unlike an adaptive management approach (Walters 2007)
wherein continuous monitoring informs future
management options. Nevertheless challenges
still remain, including limited fiscal and human
resources and the inherent difficulties with assessing fisheries in some waters (e.g., remote
locations, complex habitats, and high flows). In
some jurisdictions, little capacity or financial resources exist to undertake fishery assessments,
or there are inadequate supportive governance
structures (e.g., institutions, policy frameworks)
to incorporate such information into fisheries
management. Without information about local
fish stocks and production, it is impossible to
manage fisheries effectively or value them adequately so that their importance at local and
global scales is appropriately acknowledged.
Given the important role of assessment
in ensuring that inland fisheries are managed
sustainably in an ecosystem context and in
raising awareness about the scale, scope, and
value of inland fisheries, the authors convened
a meeting of world leaders in fisheries assessment as part of the global conference on
inland fisheries held at FAO in Rome in January of 2015. Prior to the meeting, the authors
reviewed available literature to generate questions and identify issues or challenges related
to assessment of inland fisheries that served
as the basis for discussion. Approximately 50
people from many sectors around the globe
attended the session and provided input that
developed recommendations and possible
implementation mechanisms to direct a future
48
cooke et al.
research agenda. That information is summarized here as a vision for the future of inland
fisheries in which assessment would be more
effective in enabling sustainable management
and, therefore, contributing to food security
and livelihoods while also maintaining or improving ecological integrity.
The 10 priority recommendations generated by attendees were developed as a series
of proposed actions and separated into two
themes: six recommendations focus directly
on proposed actions to improve assessment
of inland fisheries worldwide while four recommendations propose actions and considerations to support these improvements (Figure 1). The recommendations are presented
in a logical progression of steps, though the
authors recognize that the diversity of inland
fishery governance structures and the various
spatial scales at which assessments occur suggest that this progression may not be universal
and that suitable actors for addressing each
recommendation may also vary among fisheries and jurisdictions.
Assessment Recommendations
(1) Recognize the large number and high
diversity of small inland isheries
Context.—Much of the world’s inland fisheries catch comes from a large number of small
lakes, streams, and wetlands that are charac-
Figure 1.—The 10 priority recommendations derived by attendees of the fisheries assessment
symposium as part of the Global Conference on Inland Fisheries held at the Food and Agriculture
Organization of the United Nations in Rome in January of 2015. The recommendations are separated
into two overarching themes: recommendations for improving inland fishery assessments, and recommendations for supporting these improvements. Each category has been listed in descending order
as a logical progression.
assessment of inland fisheries
terized by great diversity in natural ecological
conditions (Bachman et al. 1996; Soranno et
al. 2010), anthropogenic habitat modifications
(Khoa et al. 2005; Vörösmarty et al. 2010),
fishing pressure (Post and Parkinson 2012),
socioeconomic attributes of fishers (Smith et
al. 2005), and governance arrangements (Almeida et al. 2009; Snell et al. 2013). All of these
factors affect realized fisheries outcomes, management options, and the outcomes that can
potentially be achieved: one-size-fits-all management is unlikely to be a good policy (Carpenter and Brock 2004; Castello et al. 2011;
Post and Parkinson 2012).
Recommendation.—Recognize and account for the inherent diversity of inland fisheries (in terms of ecological, socioeconomic,
and governance attributes) in assessment processes and in providing management advice.
Proposed actions.—There is a need for development of assessment methods that support differentiated management appropriate
to local conditions. This requires, first, a qualitative appreciation of how different attributes
vary among fisheries and how they interact
at local levels to drive outcomes and management options for specific fisheries (Carpenter
and Brock 2004; Lorenzen 2008). It requires,
second, methods for assessing outcomes and
management options for individual fisheries.
Two alternative, but not mutually exclusive,
approaches may be taken to this end. One approach is to develop simple assessment tools
(and methods for employing them) that may
be used locally, possibly by nonscientists (the
“barefoot ecologist” approach, Prince 2003). A
suite of fisheries assessment methods for datapoor stocks are also now available (Carruthers
et al. 2014). Another approach is through use
of empirical models. Empirical studies explore
the statistical relationships between fisheries
response variables (e.g., harvest, abundance)
and explanatory variables such as fishing effort, primary productivity, or the presence–
absence of anthropogenic habitat modifications and provide models of fish production
and potential yield. Information from multiple
fisheries can be combined to capitalize on the
variability between them and derive empirical
models. Empirical models have been used to
49
describe how fishery yield or fish abundance
responds to variation in environmental factors
(Ryder et al. 1974; Bachman et al. 1996), anthropogenic habitat modifications (Pretty et al.
2003; Khoa et al. 2005), fishing effort (Lorenzen et al. 2006), and fisheries management arrangements (Almeida et al. 2009).
(2) Expand the range of tools for ishery
assessment
Context.—Technological innovation, creativity, and need have resulted in numerous
options for expanding the traditional fishery
assessment toolbox. For example, surveys and
mobile technologies can tap into the collective experience and wisdom of inland fishers.
Survey data can be collected from fish markets
(Nasir and Khalid 2013), from landing sites
(Abobi et al. 2014), government statistics (e.g.,
household surveys; IFReDI 2013), and by mail
or phone (Dorow and Arlinghaus 2011). Anglers can also voluntarily report information
through paper diaries (Cooke et al. 2000), Web
sites (Muller and Taylor 2013; Martin et al.
2014), or mobile technologies (Papenfuss et al.
2015). Recent advances in stable isotope techniques allow for inference of fish habitat associations and diet from the microchemistry of
calcified structures (Pouilly et al. 2014). Similarly, environmental DNA (eDNA) can be used
to assess species presence–absence (Lodge et
al. 2012) and perhaps biomass (Takahara et al.
2012) and hydroacoustics used to assess abundance, distribution, and behavior (Getabu et al.
2003). Finally, the inland fishery management
toolbox can be expanded via remote sensing at
local and regional scales. Examples of remote
sensing at the local scale include unmanned
vehicles (Davis et al. 1997; Jensen et al. 2014),
stationary cameras (Sunger et al. 2012), and
receiver and sensor arrays (Hall 2007). Remote
sensing of inland fish and fisheries at regional
scales can be either direct (e.g., satellite imagebased harvest estimates; Al-Abdulrazzak and
Pauly 2014) or indirect (e.g., satellite-derived
estimates of chlorophyll a, geographic information system-based correlates of fish productivity; Fisher 2013; Lesht et al. 2013). These novel
approaches to data collection address many of
50
cooke et al.
the challenges associated with the assessment
of inland fisheries in that they tend to be noninvasive, rapid, and appropriate for systems
or resources that are difficult to sample or for
which the capacity for sampling is limited (especially over broad temporal or spatial scales).
The contribution of a range of data from such
methods provides multiple sources of information by which the accuracy of fisheries assessments can be rapidly improved.
Recommendation.—Expand the range of
tools for assessment through the incorporation, validation, and standardization of new
and integrated sampling methods (e.g., stakeholder and local ecological knowledge, household surveys, mobile technologies, microchemistry, eDNA, hydroacoustics, remote sensing,
and geographic information systems).
Proposed actions.—Researchers and managers should conduct experiments and pilot
studies aimed at advancing and refining these
tools and determining their strengths, weaknesses, benefits, and limitations for use in inland fishery assessment. For example, significant advances in eDNA are required before this
tool can be used to estimate abundance (Lodge
et al. 2012), and hydroacoustic techniques are
currently constrained by environmental and
morphological considerations such as turbulence and substrate type (Lucas and Baras
2000; Maxwell 2007). Validation of these tools
through careful observation and comparison
against contemporary tools will show the extent to which data are precise and unbiased
for a given set of conditions and procedures.
Comparison will show the extent to which a
novel tool complements or is an alternative to
a contemporary tool. Mobile technologies are
one example in that they are effectively angler
diaries in digital format. While angler diaries
(whether contemporary or digital) cannot replace formal surveys due to nonrandom and
unreliable participation (Cooke et al. 2000),
reasonable agreement between data from a
popular recreational fishing application and
both mail and creel surveys (see Martin et al.
2014; also Papenfuss et al. 2015) suggests
that widespread use via proper incentives
(e.g., information, feedback, and community)
can largely overcome participation issues. Fi-
nally, managers and researchers should be encouraged to publish their findings to develop
standards for inland fishery assessment methodology. Communication will encourage collaboration and innovation (while discouraging
duplication), and the novelty of many of these
emerging tools is a rare opportunity to coordinate and standardize both efforts and methods
across diverse inland fisheries.
(3) Standardize methods of assessment of
inland ish and isheries
Context.—Standardization of industrial
processes, languages, measurements, and data
collection techniques has been essential for
world progress (Nesmith 1985; Bonar et al.
2009). Routine data collection and assessment
techniques have been commonly standardized
in many scientific professions, including medicine (Beers and Berkow 1999), meteorology
(Lockhart 2003; Schiesl 2003), geology (Assaad
et al. 2004), and water chemistry (Eaton et al.
2005). Standardizing the assessment of inland
fish and fisheries (i.e., collection and reporting
of fisheries data using a few similar methods)
offers many advantages as well (Bonar and Hubert 2002; Bonar et al. 2009). These include a
much improved ability to compare data across
regions or time, thus meeting needs for larger
regional or global scale assessments necessary
for setting broad-scale regulations, identifying
effects of global climate change, and evaluating
adequacy of global food supplies. Standardization can also vastly improve communication
across political boundaries and control bias associated with different sampling (e.g., netting,
electrofishing, and hydroacoustics) and data
reporting techniques. When fishery biologists
have used standard assessment techniques,
benefits have been striking. For example,
Homer Swingle (1950, 1956) developed early
standard techniques to study fish populations
in southeastern U.S. ponds. The information
Swingle obtained using these standard techniques was instrumental in understanding
basic biology of fishes and how to successfully
manage them for food and sport and was used
by organizations worldwide to improve fish
production (Byrd 1973). If the data collection
assessment of inland fisheries
methods were not standardized, cross-site or
-time analyses would require calibration and
would always contain significant uncertainty.
Recommendation.—Further develop standardized and defensible methods of biological assessment of inland fish and fisheries that
include data collection, sharing, and reporting
to reflect diverse ecosystem types and enable
intra- and cross-sectoral comparisons.
Proposed actions.—Techniques to effectively sample freshwater fishes have existed for
centuries. However, getting people to change
the techniques that they are currently using
to adopt a standard is challenging, often because of potential interference with long-term
data sets, political rivalry among agencies and
countries, and tradition (Bonar and Hubert
2002). Integrating social with biological science is essential to standardization (see Bonar
and Fraidenburg 2010). Developing standard
methods and encouraging compliance with
standardized procedures requires clear statements of the advantages of using standardized
methods; development of standards within the
authority of widely respected groups that transcend political boundaries, such as the World
Fisheries Congress, the American Fisheries
Society, the European Committee for Standardization, or the International Organization for
Standardization; inclusion of many varied parties in standards development; and, depending
on the situation, either requiring or not requiring methods to be adopted. These techniques
are currently being used to develop standards
for increasingly larger regions. For example,
the American Fisheries Society recently recommended standard techniques for sampling
North American freshwater fish populations,
an ongoing process involving 284 biologists
from more than 100 North American organizations (Bonar et al. 2009). The European community has a continuing program to develop
fish sampling standards involving many European countries (e.g., CEN 2003; CEN 2005; and
others). Standardization on even larger, global
scales has been discussed—an increasingly
important issue with advances in worldwide
communication and global threats to freshwater fisheries. For situations in which methods
standardization is not possible among areas,
51
gear calibration and comparison techniques
allow gear types to be compared (e.g., Peterson and Paukert 2009) or ground-truthed for
comparison. However, reducing the number
of situations in which conversion factors must
be applied improves comparison and communication. Finally, recognition that widespread
standardization is not an immediate outcome
of developing standard procedures is important. Adoption of standard procedures often
takes time and requires continued effort. Even
small movement toward standardization,
however, improves communication and data
analysis. Therefore, patience and persistence
are necessary attributes to those who wish to
standardize.
(4) Improve estimation and reporting of
relevant inland ishery statistics
Context.—Reliable estimates of inland
fishery production, consumption of inland
fishery products, participation in fishing, and
other relevant indicators are important to
support adequate valuation of inland fisheries and consideration in sectoral and intersectoral policies. The development of relevant and comparable indicators, however,
is in itself challenging, given the diversity of
the fishery sector and the products that it
provides (e.g., fish that are traded, consumed
for subsistence or exchanged through social
networks, recreational fishing opportunities
that need not involve any harvest; Smith et al.
2005). Moreover, the diffuse and widely distributed nature of most inland fisheries and
associated landing locations and markets often precludes the use of the reporting systems
commonly used in marine commercial fisheries. Carefully designed sampling schemes are
rarely used, the exceptions being large water
bodies such as reservoirs and commercial
fishing concessions. As a result, reliable and
relevant inland fisheries statistics are often
absent. Consequently, inland fisheries remain
poorly reported or even ignored in national
statistics and in considerations of food security. A systematic undervaluation of the
contribution of inland fisheries may extend
throughout the value chain.
52
cooke et al.
Recommendation.—Improve the estimation and reporting of reliable and relevant inland fisheries statistics through methods that
account for the diversity of products provided
by the fishery sector and its diffuse and distributed nature.
Proposed action.—A reform of systems for
estimating and reporting inland fisheries statistics is long overdue. Reforming reporting
systems in a coordinated manner at the local,
national, and international levels would greatly strengthen the global statistics provided by
FAO. Due to the diversity and diffuse nature
of inland fisheries, development of effective
data collection systems requires a good understanding of fisheries and the products that they
provide. In addition to catch reporting systems
covering major landing sites or markets, a variety of approaches have been used to improve
estimates of catches, fishing effort, and other
indicators. Household surveys can be used to
provide valuable data when a substantial share
of the catch is neither marketed nor landed at
defined landing sites (e.g., for subsistence fisheries; FAO 2014) and are potentially useful for
gathering assessment data. Data generated
from household surveys may include estimating food consumption, household income,
and food production decisions, contribution
of fisheries products to livelihoods, time, and
capital investment in fishing activities (Beaman and Dillon 2012). It is also possible to
collect detailed data suitable for use in fisheries assessments from household surveys, for
example on catches from different water bodies or habitats, species composition, seasonal
change in catch composition, and use of fishing
gears (Khoa et al. 2005; Hortle 2007; Almeida
et al. 2009).
(5) Evaluate the effectiveness and impacts
of inland isheries enhancements through
assessment
Context.—Active enhancement of inland
fisheries through stocking or habitat modifications is widespread. For example, in the United
States, state fisheries management agencies
release more than 1.7 × 109 hatchery-reared
fish of more than 100 species and stocks an-
nually, and state agencies expend 21% of their
budgets on practical enhancement activities
(Ross and Loomis 1999; Halverson 2008). In
China, state and private entities operate fisheries enhancements in more than 80% of the
country’s vast acreage of reservoirs, yielding
more than 2.5 million metric tons of fish annually (Li 1999; Miao 2009). Rural people in the
tropics implement a plethora of fisheries enhancement measures in public, communal, or
private water bodies (Welcomme and Bartley
1998; Amilhat et al. 2009). Fisheries enhancements combine elements of capture fisheries
and aquaculture and are subject to specific
management considerations. Enhancements
can be effective in increasing fisheries yields or
opportunities for recreational fishing and wider socioeconomic benefits, provided that conditions are conducive and the enhancement
measures well designed. In practice, however,
many enhancements are likely to be ineffective
and some have caused demonstrated ecological damage (Cowx 1994; Lorenzen et al. 2012).
Unfortunately, the extent of inland fisheries enhancements, their contribution to catches and
other fishery performance measures, and their
ecological impacts are poorly documented and
evaluated.
Recommendation.—Quantify the contribution that enhancement measures such as
stocking or habitat modifications make to inland fisheries production and assess where
and when such active measures can contribute
positively to management outcomes and when
they should be avoided.
Proposed actions.—Collection of data to
quantify the contribution of enhancements
to inland fisheries harvest and other fisheries
performance metrics should be encouraged
as an integral part of the assessment process.
Separate recording of catches derived from
enhancements in fisheries statistics is a first
step, even though this is neither straightforward nor sufficient to assess net contributions
(Klinger et al. 2012). Scientific knowledge and
assessment tools have matured to the extent
that they can be used in an effective and timely
manner to improve emerging and established
enhancements. Continued progress in the assessment and management of enhancements
assessment of inland fisheries
will likely require interdisciplinary studies
that combine theory development with experimental tests of key assumptions and long-term
manipulative experiments (Lorenzen 2014).
The authors further encourage the development of validated and standardized methods
for reforming enhancements (Cowx 1994; Lorenzen et al. 2010).
(6) Synthesize global inland isheries status
and drivers
Context.—The global harvest of inland fisheries reported to FAO has slowly increased by
about 0.15 metric tons per year since 1950—
11.6 million metric tons in 2012. This is in
stark contrast to the global harvest of marine
fisheries that plateaued around 80 million metric tons in 1990 (FAO 2014). Although these
data indicate that inland fisheries currently
comprise only 11–12% of the global harvest,
some have speculated that the inland fisheries harvest is markedly underestimated, owing
to inadequate resources to sufficiently record
catches; the exclusion of subsistence, artisanal,
and recreational harvest; or deliberate misrepresentation of reported landings (Cooke
and Cowx 2004; Allan et al. 2005; Welcomme
et al. 2010; Beard et al. 2011). FAO argues that
“inland waters remains the most difficult subsector for which to obtain reliable capture production statistics” and states that catches may
even be overestimated in some years given the
high level of interannual variation reported by
some countries (FAO 2014). Therefore, scientists unanimously agree on the probable inaccuracy of the reported harvest from inland
fisheries at the global scale. Beard et al. (2011)
argued that a less-biased global estimate could
lead to greater investment in the management
and restoration of inland fisheries as the sector
faces increasing competition with hydropower,
irrigated agriculture, and transportation for
the use of freshwater.
Recommendation.—Improve global models for estimating inland fish production
through regional or subregional validation,
standardization of sampling approaches, and
consideration of more potential explanatory
factors (e.g., climate, latitude, catchment and
53
water body characteristics, migratory status of
species).
Proposed actions.—Simple models that
predict inland fish production based on lake
size alone suggest that sustainable production
could be as high as 90 million metric tons (Welcomme 2011). Although Welcomme (2011) acknowledged that as a “crude” estimate, it suggests that more refined attempts to estimate
global inland fish production were possible. To
this end, the development of multiple modeling approaches is encouraged. For example, at
the subcontinent or regional scales at which
inland fisheries production is more reliably
monitored, scientists could develop standardized methods to measure relatively simple in
situ characteristics of water bodies (e.g., Secchi
disk depth for lakes, mean discharge for river
systems, mean surface water temperature,
and mean chlorophyll a). These data could
be used to develop predictive models, with
separate ones likely to be needed for rivers
and lakes (e.g., Welcomme and Hagborg 1977;
Schlesinger and Regier 1982). Other models
to predict fish production could be developed
that rely on remotely sensed data (e.g., atmospheric climate, surface water temperature,
chlorophyll a, land cover in the catchment,
water basin morphometry, human population
density, or other economic development indicators) available from satellite imagery or
geographical information system data layers.
These models could be global in scope or as
broad as reliable inland fish production data
permit. Ideally, these remotely sensed models
would be validated with the regional models
that use in situ measurements. Finally, special
research focus should be allocated towards the
continents of Asia and Africa, where, in 2012,
13 countries comprised nearly 75% of the
global inland fishery harvest (FAO 2014). Applying these complementary methods within
these productive regions would yield multiple
benefits. First, it could identify key drivers (i.e.,
land use, productivity, and human population
characteristics) of inland fisheries harvest and
potentially provide a sense of how a changing ecosystem could affect inland fisheries.
Second, given that both Asia and Africa possess a wide diversity of lakes and rivers, these
cooke et al.
54
methods could begin to reveal the relative contribution of these water body types to inland
fisheries production. Finally, a more accurate
estimate of inland fishery production on these
continents would greatly improve the accuracy
of the global estimate.
Supporting Recommendations
(1) Manage isheries based on scientiic
evidence
Context.—There is growing recognition
that resource management actions tend to be
based on intuition or past experiences of the
manager (i.e., faith-based fisheries; Pullin et
al. 2004; Hilborn 2006), even when credible
evidence has been synthesized and suggests a
different approach (Walsh et al. 2015). There
have been calls for the environmental and conservation world to draw upon techniques used
in the medical realm to synthesize information
such that decisions are based on objective scientific evidence (Pullin and Knight 2001). Systematic reviews (which incorporate meta-analysis) ensure accessibility of the best available
evidence and should yield a more efficient and
unbiased platform for decision making (Pullin and Stewart 2006), such that environmental managers do more good than harm (Pullin
and Knight 2009). Meta-analyses are already
used in aquatic science (e.g., Smokorowski and
Pratt 2007; Chapman et al. 2014) but tend to
be done with less rigor than a formal, systematic review. Indeed, broad consultation, peer
review of the science, and use of systematic
reviews to facilitate evidence-based conservation and management are essential, yet lacking, despite a receptive scientific community
and the existence of frameworks for doing so
(i.e., Pullin and Stewart 2006).
Recommendation.—Develop and implement rigorous approaches to evaluate various inland fisheries management actions to
provide the evidence base to support management, mitigation, compensation, and restoration and enhancement activities
Proposed actions.—To move away from a
faith-based approach to fishery management,
a number of specific actions are recommended.
For example, resource management agencies
could incorporate large-scale management
experiments that use a before-after-controlimpact or adaptive management approach to
evaluate the effectiveness of their actions. The
fishery management community should conduct systematic reviews (Pullin and Knight
2001) on common management interventions
relevant to inland fisheries (e.g., is fish passage effective at maintaining and restoring
river connectivity, and if so, under what conditions? Do freshwater protected areas benefit
fish populations outside of the protected area
such that they are a viable management strategy? Do voluntary regulations embraced by
fishers work as well as those that are dictated
and enforced by regulators?). Finally, fishery
managers need to rethink the basis for their
various management decisions and use an evidence-based approach over simply following
intuition or tradition. Doing so will ensure that
limited resources are deployed and utilized appropriately and that management actions will
be more likely to produce the beneficial outcomes they were designed to achieve.
(2) Communicate inland isheries status,
threats, and management and policies
Context.—The public is generally unaware
of the benefits derived from inland fish and
fisheries (Lynch et al. 2016) and their current
status as the most imperiled group of animals
worldwide (Strayer and Dudgeon 2010). This
lack of awareness suggests that effective communication and engagement models are not
being successfully implemented by fisheries
professionals or their agencies. Increasingly,
researchers are becoming aware of the need to
garner public support for research and conservation initiatives (Cooke et al. 2013a). Information gathered from local fishers and experts
has been used to guide research efforts to success and improved socioeconomic outcomes
(Johannes and Neis 2007; Hind 2015). There
are also numerous instances of research and
conservation activities that have been made
successful as a result of the participation of
citizen scientists, fishers, and others who contribute time, personal finances, and expertise
assessment of inland fisheries
to support such endeavors (Granek et al. 2008;
Fairclough et al. 2014). The success or failure
of conservation efforts has been largely determined by stakeholder support in some cases
(Jentoft et al. 2012; Sawchuk et al. 2015).
Yet, though it should be considered an essential part of the process, the outcomes of research projects or conservation initiatives are
not widely communicated to interested stakeholders (Hulme 2014; Young et al. 2014). To
encourage a broader understanding of the issues currently facing inland fish and fisheries,
positive relationships, and ongoing support
for proposed solutions, fisheries professionals should adopt strategies for communicating
more effectively with the general public (Cooke
et al. 2013a). Ultimately, a more engaged and
better informed populace is more likely to have
a positive effect on evidence-driven policy development (Cooke et al. 2013a; Young et al.
2014).
Recommendation.—Develop a communications plan that uses appropriate and accessible
communication channels to more effectively
package, present, and transfer information on
inland fisheries to a range of target audiences
so as to raise awareness of inland fisheries values and issues, impact human behavior, and influence relevant policy and management
Proposed actions.—Improvements in fisheries science engagement should first be addressed by developing strategies for effective
communication, including the identification of
barriers to public engagement (see Cooke et
al. 2013a) and suitable methods for overcoming these barriers. Effective methods of communication will vary among target audiences,
among regions, and even at the fishery scale,
suggesting that strategies should not attempt
a one-size-fits-all model for communication,
but be based on stakeholder research, fisher
knowledge, and other fishery-specific information (Hind 2015). For example, some regions
may be more likely to use cell phone technology (applications) than others, but may be
limited by technological differences (i.e., many
African regions have extensive access to cell
phones but not smartphones and are, thereby,
limited to what applications may be used; Bratton 2013). Second, training in communications
55
for researchers should be considered an institutional priority, and funding bodies should
consider incorporating standards for evaluating outreach efforts and quality to support this
need. Information about outreach and knowledge transfer is not generally included as a
mandatory part of training, nor has this need
for improved communication and engagement
been incorporated into institutional standards
(Cvitanovic et al. 2015).
(3) Engage stakeholders in management
processes
Context.—Dialogue between fishery professionals and stakeholders has traditionally
been unidirectional, for example, with research
outcomes translated to policy or management
initiatives and instituted as a top-down mechanism (Stöhr et al. 2014). However, the need
for improved dialogue with stakeholders has
become recognized within the scientific and
fisheries management communities and, with
it, the need for that dialogue to be meaningful,
such that it allows for development of trusting
partnerships and ongoing relationships (Reed
et al. 2014; Sawchuk et al. 2015). The term
“two-way dialogue” refers to a more open communication process in which stakeholders can
provide information, perspectives, and views
on key issues to researchers, managers, and
policymakers.
Resource research and management needs
to be viewed as a symbiotic exercise in which
local experts and stakeholders provide scientists with locally relevant details and community context, while scientists and management
provide local communities with the expertise
required to address that context (Kettle et al.
2014). Improved two-way dialogue also provides additional opportunities for education,
which has been shown to increase the effectiveness of voluntary adherence to regulations
in some sectors (i.e., in recreational fisheries;
Cooke et al. 2013b). Moreover, encouraging
voluntary adherence to regulations and improving access to education (e.g., best practices for fishers) greatly reduces the need for
enforcement and cumbersome regulatory processes (Grafton 2005; Cooke et al. 2013b).

Recommendation.—Create mechanisms
to facilitate dialogue between and among diverse stakeholders internal and external to
the sector.
Proposed actions.—Prior to any inland
fisheries management action, key stakeholders should be identified (see Aanesen et al.
2014 for a detailed discussion about stakeholder types and identification processes) and
adequate consultation mechanisms should be
instituted and followed. Consultation serves to
build more positive relationships and increase
the likelihood of adherence to voluntary regulations (Cochrane 2001). Further, the consultation process can be used to develop balanced
stakeholder networks to address any issues of
equity among stakeholders (Grafton 2005).
During research or management processes (including assessment), dialogue points
should be built into management and research
timelines such that communication occurs at
frequent and regular intervals (Ratner and
Smith 2014). Not only does formalizing the
dialogue process support efforts to increase
procedural transparency, but it can also serve
as a check and balance function for monitoring the effectiveness of the process (Ratner and
Smith 2014). In cases where conflict situations
are a concern, dialogue should be facilitated
by experienced intermediaries (Johnson and
Griffith 2010). Finally, it is crucial to maintain
ongoing two-way dialogue and partnerships
with stakeholders. Thus, efforts to maintain
two-way dialogue should include the development of partnerships with local fisheries
groups, nongovernmental organizations, and
other appropriate partners (Aanesen et al.
2014).
The Way Forward—Science to
Support Action: Managing
Fisheries within Broad Ecosystem
and Sociopolitical Contexts
It is now widely recognized that fisheries must
be managed in a broad context—one that recognizes the influence and dependency of fishing activities on the ecosystems that support
them; on other uses of aquatic resources; and
on the socioeconomic, governance, and policy
contexts that shape fishery resource use (McCafferty et al. 2012). Inland fisheries are particularly affected by other sectors that place
demands on freshwater resources (biodiversity conservation, agriculture, industry, mining,
and urban development), but also by impacts
within catchments (forestry, sedimentation)
and increasingly by climate change. To operate
within this complex and shifting milieu, fisheries science, management, and policy need to be
fully integrated with these wider sectors and
their decision support frameworks. Fishery assessments that produce complex models and
harvest predictions must be able to present
such information in language and formats that
inform fishery activities but are also accessible
to the different sectors engaged in land and
water management and policy.
Assessments should inform inland fishery management as well as other sector planning and decision making (e.g., environmental
flows, integrated water resource management)
at appropriate scales (e.g., river basin, bioclimatic region, and jurisdiction) through
stakeholder engagement; valuation of ecosystem services, including fisheries outputs; and
evaluation of policy alternatives with consideration of trade-offs. The recommendations prioritized by the symposium attendees and the
thought leaders involved with this paper serve
to provide a globally informed template for
pursuing improved assessment and management of inland fisheries. These changes would
be further supported by the broader recommendations prioritized by the group (supporting recommendations) that will help to ensure
that the assessment and management components of contemporary resource management
are integrated. It is our collective hope that the
changes and improvements recommended for
the assessment process provide practitioners
with the forward-looking ideas and tools necessary to generate sustainable inland fisheries.
If implemented, these recommendations have
the potential to shape science-based management at regional and global scales. Failure to
do so will further retard our collective ability
to sustainably manage inland fisheries not only
in terms of sector-based threats like overhar-
assessment of inland fisheries
vest, but also in terms of external threats such
as habitat alteration and water taking, which
are permanently altering the fishery production of inland waters.

Abstract.—To better reflect the true value of inland capture fisheries in the international discourse, we provide a new estimate of theoretical annual fisheries harvest from inland waters per continent and type of aquatic habitat. The estimate is
based on an assessment of recent estimates of global inland aquatic habitat areas
and average yield measurements from these habitats.
We estimate the global theoretical annual inland fisheries harvest to be approximately 72 million metric tons. Our estimates of harvest by continent are on average
6.5 times higher than the official catch data submitted to the Food and Agriculture
Organization of the United Nations. Reasons for the higher values in this study are
discussed and include the use of improved estimates of global freshwater surface
area and yield estimates from a wide variety of water bodies. Improved estimates of
the theoretical harvest from inland water capture fisheries would greatly increase
the visibility and the importance of the sector and help ensure its proper consideration in policies addressing livelihoods and food security.
Introduction
Freshwater capture fisheries (harvest from
wild stocks in inland waters) provide income
and nutrition for hundreds of millions of people worldwide (FAO 2014c) and are dependent on functioning freshwater ecosystems.
The major external threats to freshwater fisheries are degradation and loss of freshwater
ecosystems (Welcomme 2011a) as well as
loss of access to those ecosystems. Destructive and unsustainable fishing practices further threaten inland fisheries (Allen et al.
2005), and in many cases, individual species
are overexploited. Inland capture fisheries
are especially important in landlocked countries in the developing world where they provide an important source of animal protein
(Lucas and Marmulla 2000). Countries with
significant coastlines (e.g., Kenya, Tanzania,
Bangladesh, Cambodia, and Nigeria) are also

highly dependent on large inland systems for
their fish supply (UNEP 2010).
Africa and Asia together accounted for
more than 91.6% (23.3 and 68.4%, respectively) of the reported inland fish harvest
worldwide in 2012 (FAO 2014a). Since reporting started in 1950, there has been a steady
increase in reported inland capture fisheries
harvest, with the current level of annual harvest being approximately 11.6 million metric
tons (FAO 2014a, 2014c).
The official reported inland water surface
area in the world totals 4.6 million km2 (FAO
2014b). Globally, this water surface area would
correspond to a yield of 25 kg/ha/year or 1.7
kg/person. However, both the inland water
surface area estimates of 4.6 million km2 and
the 2012 reported inland capture harvest of
11.6 million metric tons have some concerns
attached to them. For the reported inland water areas, this estimate is based on water areas
reported by only 67% of the world countries,
64
lymer et al.
indicating that this estimate must underrepresent the actual inland water area (FAO 2014b).
Furthermore, the value of inland capture fisheries is not sufficiently recognized and frequently
underestimated, especially in terms of subsistence fisheries in developing countries (Mills et
al. 2011). Moreover, recreational fisheries are
seldom included in official catch data (Cooke
and Cowx 2004). Hence, both officially reported
inland water areas and inland capture fisheries
harvest figures are likely to be underreported.
Globally, freshwater is a very strategic resource because of its multiple and important
uses (e.g., drinking water, hydroelectric generation, and irrigation). This results in high
pressure from different freshwater sectors and
users, which will most likely increase with a
growing population that is estimated to reach
9.6 × 109 in 2050 (UN 2013). The increasing
pressure on water resources will put more
stress on the inland capture fisheries sector. It,
therefore, becomes increasingly important to
provide a better estimate of potential harvest
from inland capture fisheries and to achieve
a better understanding of its importance for
food supply and food security. Improving this
estimate will also benefit policymakers who
rely on this information to make informed decisions about water management.
To better reflect the value of inland capture fisheries, we have extended the idea of
Welcomme (2011b), who estimated harvest
based on the relationship between lake size
and harvest. To this end, we provide further estimates on the theoretical annual harvest from
inland capture fisheries per continent and type
of aquatic habitat, based on recent estimates
of global inland aquatic habitat areas (Lehner
and Döll 2004; Downing 2009) and habitatand continent-specific fisheries yield data. The
intention of this exercise is not to provide the
exact potential global harvest for inland capture fisheries, but rather to estimate the potential levels of global and regional yields to serve
as a basis for further more detailed studies.
Method
A global assessment of area of five different
aquatic habitats (AqH) was constructed that in-
cluded permanent lakes, reservoirs, rivers (including streams), floodplains (including freshwater marches), and other wetlands (including
rice fields). The area value (AreaAqH global) for the
habitats was determined as the average values
from the assessments of Downing (2009) and
Lehner and Döll (2004). Swamp forest, flooded
forest, bogs, fens, mires, intermittent wetlands,
and lakes were grouped together as other wetlands. The following nonfreshwater aquatic
habitats were excluded from the analysis as harvest from these systems would not be reported
as derived from inland capture fisheries: coastal
wetland, pans, and brackish/saline wetlands
(De Graaf et al. 2015). The distribution of aquatic habitats per continent (AreaAqH continent) was
calculated using the distribution assessment
from Tables 4 and 5 of Lehner and Döll (2004).
To obtain a measure of the mean annual
fish yield (kg/ha/year) per continent and per
aquatic habitat type (YieldAqH continent), data were
collected from (1) the literature, and (2) a Food
and Agriculture Organization of the United Nations database (FAO 1997). The latest data
were used where there were duplicate measures from the same water body. The compiled
data set of fish yield from 793 specific water
body areas organized by continent and the five
aquatic habitat types was further processed in
Statistica 12 (StatSoft, Tulsa, Oklahoma) where
outliers where removed until a two-tailed normal distribution was obtained. Thereafter, the
mean annual yield and the 95% confidence interval per continent and aquatic habitat were
calculated for the remaining data (i.e., 697 specific water bodies).
For 11 aquatic habitats in continents
where yield data were missing, the yield was
estimated using two different approaches. The
following seven aquatic habitats were estimated from the most similar habitat and continent
in terms of latitude and average temperature.

Four aquatic habitats where there were no

estimated by applying a 0.1 factor to the habitat corresponding to the average data for tropical systems as follows:

The total annual harvest (TFH) from the
areas assessed was obtained by multiplying
the obtained yields (YieldAqH continent; mean and
95% mean confidence level) by the aquatic
habitat type area (AreaAqH continent).
TFH = YieldAqH continent × AreaAqH continent
As a comparison to TFH, we calculated (1)
global fish biomass (FBGlobal), (2) fish production (FPGlobal) in lakes, reservoirs and rivers, and
(3) the theoretical global fish yield from lakes
based on net primary production (TFYNPP). The
global fish biomass (FBGlobal) and global fish
production (FPGlobal) for lakes, reservoirs and
rivers was derived from the global mean fish
65
biomass (mean FBGlobal) and mean fish production (mean FPGlobal) for lakes, reservoirs, and
rivers from values in the literature and multiplied by the corresponding global area (AreaAqH
, Table 1).

lakes based on net primary production (TFHL
) was calculated from the average global valNPP

to fish harvest (Downing et al. 1990) and multiplied with the global area of lakes (AreaLakes
):

TFHLNPP = Area Lakes global × 0.1

Results
The total global area for the five different
aquatic habitats that could sustain inland capture fisheries was assessed to be 10,404,450
km2 (Table 1). Globally, we determined that the
water surface area is composed of 30.7% lakes,
2.8% reservoirs, 4.2% rivers and streams,
30.9% floodplains and freshwater marsh, and
31.4% other types of wetlands. The distribution of different aquatic habitats per continent
is presented in Table 1.
The mean fisheries yield per continent
and aquatic habitat type indicate that the highest mean yields from lakes, rivers and streams,
and other wetlands are found in Asia (Table
2). The highest mean yield for reservoirs and
floodplains are found in South America, with
the lowest mean yields found in North America
and Europe.

The global fish biomass (FBGlobal) for lakes,

Discussion
lymer et al.
We estimated the global theoretical harvest
of fish from all inland waters to be 72 million
metric tons. Welcomme (2011b) estimated
the potential harvest from only lakes to be 93
million metric tons using a similar estimate of
global lake area (Downing et al. 2006). We estimated total harvest from lakes (TFHLakes) to
be 20.7 million metric tons (Figures 1 and 2).
The difference between the two analyses is due
to the higher yield values used in the Welcomme’s (2011b) analysis, especially for smaller
size lakes that are often intensively managed
by stocking, from where the majority of the
harvest in Welcomme’s analysis originated.
Our figure of approximately 5 million
metric tons for theoretical harvest in Africa is
higher than previous estimates. For Africa, as
a whole, it was estimated that the inland waters had a potential harvest between 1.99 and
3.22 million metric tons (Vanden Bossche and
Bernacsek 1990). This difference is probably
because the total water area used for estimation was lower than the area used in our estimation. In addition, previous work estimated
the potential harvest from African rivers to
be 558,241 metric tons per year (Welcomme
1976). Our estimates from lakes, reservoirs,
and rivers are based on a large collection on
yield data, and hence, our confidence in these
data is high. The level of harvest obtainable in
different aquatic habitats is ultimately based
on the diversity and stocks of wild fish species
(biomass) and their annual productivity (Welcomme and Hagborg 1977; Christensen and
Pauly 1993; Welcomme 2001). Our harvest
estimates are compatible with independently
derived estimates of fish biomass and fish production (Figure 2). However, the theoretical
harvest assessments for floodplain and other
wetlands are less robust and display large
variation (Figure 1), with the exception of Asia
where fish harvest from floodplains and rice
fields are known to be common and several estimates of yield exist (Table 2). The basis for
fish production is mainly primary production
(Welcomme and Hagborg 1977), which is then
either respired or consumed by higher trophic
levels (Christensen and Pauly 1993). Our esti-
mate for TFHLNPP of approximately 31 million
metric tons of fisheries production from lakes
(Figure 2) based on NPP is higher than the 95%
confidence interval of the total fishery harvest
from lakes (TFHLakes). Hence, our harvest estimate for lakes is reasonable (Christensen and
Pauly 1993) and conservative compared to
earlier global NPP assessments of Huston and
Wolverton (2009) who reported a global NPP
value of 4.3 × 1015 g C)/year. Compared to official reported inland capture fisheries catches
(FAO 2014a, 2014c), our theoretical fisheries harvest (TFH) is higher for all continents
and aquatic habitats (Figure 2); globally, the
reported catches are 16% of TFH we calculated. At continent level, the largest differences
(percentage) are found in Australia and Oceania, South America, and Asia. These differences
could be an indication of low exploitation levels
of the total area for Australia and Oceania. However, underestimation and underreporting of inland catch is a more likely explanation in South
America and Asia (Coates 2002). To reach the
estimated TFH of 72 million metric tons, all water bodies would need to be managed for fisheries harvest as this is potential yield.
The total area of aquatic habitat used in
this assessment is more than double the value
of 4,560,204 km2 currently used by the Food
and Agriculture Organization of the United
Nations (FAO 2014b) for global assessments
of inland water area. However, the application
of new geographic information systems and
satellite imagery has recently made it possible
to make more accurate estimations of global
water area (Verpoorter et al. 2012). The estimates we derived are in general agreement
with other studies of specific aquatic habitats
(e.g., inland water area in Africa [Jenness et al.
2007], global river area [Downing et al. 2012],
global area of lakes and reservoirs [McDonald
et al. 2012], global lake area [Verpoorter et al.
2014], global rice field area [Halwart and Gupta 2004], and estimates of global inland water
area [MEA 2005; Fluet-Chouinard et al. 2015]).
The global theoretical inland capture fisheries estimate of harvest could be improved by
using satellite imagery to obtain more precise
large-scale area measurements (Verpoorter et
al. 2012; Fluet-Chouinard et al. 2015) and wa-
annual inland capture fisheries harvest
ter quality (e.g., chlorophyll a) measurements
(Deines et al. 2015) in fish harvest models.
In conclusion, we have provided an estimate of global theoretical annual inland capture fisheries harvest that is, on average, 6.5
times higher than the official catch data submitted to FAO. Thus, the potential monetary
and social value of inland capture fisheries and
their contribution to food security and livelihoods may be much higher than the officially
reported harvest data suggest.

Abstract.—Understanding the role and value of small-scale fisheries to livelihoods and food security is a key challenge in conserving fishery resources. This is
particularly true for small-scale inland fisheries, one of the most underreported
and undervalued fisheries sectors that also increasingly faces environmental and
societal change. Gender plays a central role in the different ways in which inland
fisheries contribute to food and nutritional security in developing countries. The
role of women in inland fisheries is significant, with millions of women contributing to dynamic capture fisheries and aquaculture supply chains. The role of women
in inland fisheries, however, is less visible than the role of men and is often overlooked in policymaking processes. The need for participatory community-based approaches has been widely recognized in natural resource management literature as
a means to capture people’s perspectives and empower marginalized groups. The
Photovoice method is increasingly used as a participatory tool in health, social, and
environmental research, but has had little adoption in inland fisheries research to
date. The aims of this paper are (1) to review and evaluate the effectiveness of an
emerging participatory method, Photovoice; and (2) to present a modified Photovoice method, applicable to the context of small-scale fisheries, to advance understanding of gender and socioecological dimensions. We outline the strengths and
limitations of the method and highlight that it can be used as a tool for triangulation
of mixed research methods or independently. We argue that Photovoice, as a par-

ticipatory tool in fisheries research, has the potential to provide rich, qualitative,
context-specific, untapped sources of knowledge to advance fisheries research and
management. The use of Photovoice in the context of small-scale inland fisheries
and aquaculture research is a timely endeavor given heightened interest to obtain
insights into the previously overlooked aspects of gender and the need for more
policy relevant information.
Introduction
The role of women in the capture fisheries
sector has traditionally been less visible with
a long-standing assumption that the sector
is dominated by men worldwide (Davis and
Nadel-Klein 1992; Williams et al. 2004; Bennett 2005). This incorrect assumption has
been reinforced by the exclusion of women
from registering in the sector in some countries (HLPE 2014). Women and men, however,
are increasingly viewed as both having an
important role in fisheries and aquaculture
worldwide (Allison and Ellis 2001; FAO 2006,
2012). For instance, a recent study by Mills
et al. (2011) provided the first known estimate of gender characteristics in the capture
fisheries sector worldwide. The authors estimated that 50% of the 120 million fishers employed in capture fisheries were women, with
the vast majority employed in postharvest activities (such as processing and packaging) of
small-scale fisheries in developing countries.
In terms of the aquaculture sector, comparable estimates about gender characteristics to
those for capture fisheries do not exist. However, entry into aquaculture is known to have
fewer gender barriers than capture fisheries,
resulting in more women actively participating in diverse aquaculture activities (including preharvest, harvest, and postharvest activities; Weeratunge et al. 2010; Williams et
al. 2012a).
As a result of limited gender data in fisheries and aquaculture, little policy attention
has traditionally been given to the gender dimension in these sectors. Nevertheless, there
have been some recent promising attempts to
promote a more holistic view of fisheries and
aquaculture in policy, including greater attention to gender (FAO 2012, 2015; Williams et al.
2012b). For example, the Food and Agriculture
Organization of the United Nations-led Volun-
tary International Guidelines on Securing Sustainable Small-Scale Fisheries in the Context
of Food Security and Poverty Eradication (FAO
2015) recognizes the important role of gender
in relation to equitable access to resources,
decent work, management voice, and activities, among others. The expansion of fisheries
policy discourses to include a more holistic approach to fisheries management is resulting in
an increasing need to include gender in the understanding of both social (Weeratunge et al.
2010; Williams 2010; Harper et al. 2013; HLPE
2014) and ecological (Kleiber et al. 2015) systems. For example, a recent review by the High
Level Panel of Experts on Food Security and
Nutrition (HLPE 2014) highlights that gender
can influence the different mechanisms that
determine access to fish and nutrition, both
within the general population (as consumers)
and population groups directly involved along
supply chains (as producers, processors, and
traders). Women can also play a dominant role
in prioritizing food for household members
(Quisumbing et al. 1995; Porter 2012) and
have been identified as providing an untapped
potential source of valuable local ecological
knowledge for improved fisheries management (Kleiber et al. 2015).
A gap in understanding gender patterns in
fisheries and aquaculture, however, continues
to be widely reported in the literature (FAO
2009, 2014; Béné et al. 2016). More specifically, a dearth of gender-disaggregated data in
the fisheries and aquaculture sectors exists,
which limits the accurate understanding of
how these sectors function (Geheb et al. 2008;
Harper et al. 2013). A recent review by Kleiber
et al. (2015) highlights that biases in sampling
methods and research have led to significant
gaps in gender-relevant data in small-scale
fisheries. This paper aims to address this information gap by (1) reviewing and evaluating
in the frame
the effectiveness of Photovoice as an emerging method in community-based participatory
research, and (2) presenting a modified Photovoice method, applicable to the context of
small-scale fisheries, to advance understanding of gender dimensions and socioecological aspects of fisheries and aquaculture. This
review aims to connect thinking about gender
dimensions in fisheries and aquaculture with
respect to (1) the roles and contributions of
women and men, (2) the varying socioeconomic benefits they obtain, (3) the constraints
they experience, and (4) the characteristics of
the fisheries. We argue that Photovoice serves
as a lens to provide a richer understanding of
socioecological dimensions of small-scale fisheries and aquaculture.
Photovoice—Addressing the
Need for Gender-Sensitive
Methodological Approaches in
Fisheries
The use of participatory approaches in research have arisen to provide a more in-depth
analysis of the views of local people that could
otherwise not be achieved through standard
social methods such as questionnaire surveys
(Chambers 1992; Pretty et al. 1995; Schreckenberg et al. 2010). The application of participatory approaches, during the past two
decades, has increased in literature associated
with the management of natural resources.
The drive to include a more participatory approach to fisheries research has largely arisen
from a number of perspectives, including the
move towards interactive governance and participation in fisheries management, as well as
the importance of collaborative learning in
small-scale fisheries (Wiber et al. 2009; Kolding et al. 2014; FAO 2015).
Participatory research is described as having considerable, yet often unrealized, potential in advancing fisheries research globally
(Wiber et al. 2009). In fisheries literature, a
range of participatory methodologies have
been implemented that have been classified
into four models as described by Hoefnagel et
al. (2006):
1.
2.
3.
4.
79
Deference model—requiring the role of
fishers as research assistants (e.g., Ticheler et al. 1998);
Experience-based knowledge model—emphasizing fishers’ observations as a supplement to research-based knowledge
(e.g., Wilson et al. 2006);
Competing constructions model—understanding differences in stakeholder objectives leading to biases in presenting knowledge (e.g., Finlayson. 1994); and
Community science model—promoting
collaborative fisheries science through incorporation of models 1–3 with effective
communication.
Hoefnagel et al. (2006) suggests that
the ideal method for participatory fisheries
research is the community science model of
interaction, which provides a more collaborative and holistic approach to the development
of research by scientists and fishers. Although
a range of qualitative and quantitative methods have been applied in fisheries and aquaculture research, flexible and creative tools
have been called for to (1) capture the complexity of context specific factors (Harper et
al. 2013; Kleiber et al. 2015), (2) produce policy relevant results (Wiber et al. 2004), and
(3) integrate the views and realities of fishers
within the management process (Krause et al.
2015).
One innovative community-based participatory research method that has been increasingly reported in the literature as having
the potential to offer considerable promise
for use with marginalized, often neglected, illiterate populations is the Photovoice process
(hereafter referred to as Photovoice). Photovoice is a unique form of community-based
participatory research founded on the principles of feminist theory, constructivism, and
documentary photography. The originators,
Wang and Burris (1997:369), describe Photovoice as a process by which ‘‘people can identify, represent and enhance their community
through a specific photographic technique.”
The Photovoice process involves providing
participants with the opportunity to take photographs of a particular community issue that
80
simmance et al.
are then used to facilitate participants’ critical reflections. Throughout the process, participants have control over what they document, what conclusions to report, and how to
catalyze change in their communities (Wang
and Burris 1997). The Photovoice process
typically comprises several stages, including
recruitment and training, photography assignment, group or individual selection and
discussion of photographs, coding of themes
from the photographs, and a final phase to
create research outputs (Wang et al. 1997;
Castleden et al. 2008). The theoretical principles underpin the overarching goals of Photovoice, which are “(1) to enable people to record and reflect their community’s strengths
and concerns; (2) to promote critical discussion and knowledge about important community issues through large and small group
discussions of photographs; and (3) to reach
policymakers” (Wang and Burris 1997). At its
center, Photovoice seeks to make community
needs more visible and to empower illiterate
participants to advocate for changes at the individual, community, and policy levels (Wang
and Burris 1997). As a participatory method,
Photovoice offers considerable promise for
use in working with vulnerable, uneducated,
and marginalized populations, such as women in the fisheries sector, due to its flexibility
in design and use of photography as a means
of language. Photovoice uses the means of
photography to capture community issues
and interests through a research process directed towards equal sharing of research decisions and empowerment of participants.
The participatory method has proven to be
successful in capturing complex context specific issues, as well as producing high-quality,
richer, and policy-relevant research (Bennett
and Dearden 2013; Kong et al. 2015). Furthermore, by facilitating closer participant–researcher interactions, Photovoice provides a
promising tool in meeting the desired community science model of interaction in participatory fisheries research. Last, Photovoice may
be effective in gathering sensitive gender information, which, as highlighted by Williams
et al. (2012a), is best achieved by gathering
data about “gender roles and contributions…
within their context and characterized with
respect to economic, social and individual assets and people’s needs.”
Review of Photovoice in Natural
Resources Studies
A comprehensive overview of the application
of Photovoice in public health and related disciplines can be found in the work by Hergenrather et al. (2009) and Catalani and Minkler
(2010). Given the increasing application of
Photovoice within the field of natural resource
management, a comprehensive literature review was carried out to evaluate the use of
Photovoice within this broad area of research.
The literature review included the search
terms “Photovoice,” “Photo-voice,” and “Photo
voice” in two main search engine domains:
Science Direct and Web of Knowledge. The
initial search using these key words resulted
in 113 peer-reviewed articles. After reviewing all abstracts and removing those that did
not lie within natural resource management
literature, a total of 10 studies were identified
for evaluation (Bosak 2008; Castleden et al.
2008; Baldwin and Chandler 2010; Beh 2011;
Tanjasiri et al. 2011; Berbés-Blázquez 2012;
Bennett and Dearden 2013; Bisung et al. 2015;
Crabtree and Braun 2015; Kong et al. 2015).
From this evaluation and building on work by
Palibroda et al. (2009), a summary of the advantages and limitations of applying the Photovoice method was drawn (see Table 1). The
use of Photovoice in fisheries and aquaculture
research has, to our knowledge, only been applied to a small number of studies, with only
one reported study carried out in a developing country and no reported studies within the
context of small-scale or inland fisheries (Bennett and Dearden 2013).
Overall, the evaluation reveals growing
recognition that Photovoice provides a powerful tool in addressing complex social-ecological
issues and in capturing unique perspectives of
marginalized populations in diverse settings
(Berbés-Blázquez 2012; Bennett and Dearden
2013; Kong et al. 2015). In addition, a few studies highlight that Photovoice generated more
enriched data and opportunities for mutual

context. It is not surprising, therefore, to find
that during the previous decade, Photovoice
has evolved into a more flexible participatory
methodology from Wang and Burris’s (1997)
original static description. As evident from
the review presented here, Photovoice has
increasingly been modified and applied to fit
a diverse set of cultures, research topics, and
geographical contexts (Castleden et al. 2008;
Bennett and Dearden et al. 2013).
Although many successful modifications of
the Photovoice method exist, the development
of an improved version of the Photovoice process was deemed necessary within this review
to address: (1) inherent challenges in participatory small-scale fisheries research, and (2)
limitations reported with applying Photovoice.
Standard stages involved in the Photovoice
process were modified based on standard
steps from Wang and Burris (1997) and on
best practices of steps taken from studies (see
Appendix A). Taking into account these modifications and steps suggested by other studies
(Castleden et al. 2008; Bennett and Dearden
2013), an improved eight-step Photovoice process was developed, as described below.

outlined in Table 1.
The modified process serves as a flexible tool for application within the context of
small-scale fisheries, and to be adaptable to fit
the particular needs, budget, and timescale of
a research project. Box 1 outlines in detail the
steps and proposes questions that aim to understand socioecological aspects of small-scale
fisheries through a gender approach.
Conclusion
Photovoice has increasingly been modified
and applied to fit a diverse set of cultures, research topics, and geographical contexts (Castleden et al. 2008; Bennett and Dearden et al.
2013). Limitations have been reported that
are deemed manageable, and the strength
of Photovoice as a participatory tool providing rich qualitative and context specific data
has been highlighted by several studies. A
modified version of Photovoice is presented,
which addresses limitations, builds on Wang
and Burris (1997) and best practices applied
and can be taken forward in the context of
small-scale fisheries in a gender-sensitive approach. Through the lens of photography, the
method serves to portray context specific real-life imagery of community issues through
the unique perspectives of participants over
and above what other traditional methods can
capture (Bennett and Dearden 2013; Kong et
al. 2015). In addition, the Photovoice process
allows marginalized peoples to become empowered and more able to advocate for change
at the individual, community, and policy levels (Wang et al. 1998). This paper describes a
modified and flexible Photovoice method applicable to understanding rich context-specific social and ecological information in diverse
small-scale fisheries contexts. This improved
Photovoice method, applicable to small-scale
fisheries, contributes to the growing methodological literature in fishery research and
provides a timely endeavor to advancing wider social-ecological understandings of smallscale and inland sectors.

Box 1. Step-by-Step Guide to the Photovoice Methodology
Stage 1. Community connection and consultation: This stage requires sufficient time
and effort to establish rapport and build trust with fishers to retain high quality participant participation and overcome dilemmas inherent in fisher–researcher relations.
Prolonged immersion in the field, collaboration with local experts, and transparent communication with community members are recommended.
Stage 2. Planning a Photovoice project: The following considerations, in addition to
generic project planning prerequisites, should be addressed:
1.
2.
3.
4.
Budget: When working in often remote fishing communities, additional travel costs
to and from case study sites, risks of camera theft or damage, and transport to an
identified photograph development store should be factored into project costs.
Logistics and administration: The development of consent forms, transport arrangements, and identification of where to develop photographs need to be arranged early on in the project.
Equipment: Funding might be a deciding factor regarding the selection of camera for
the project. Low-cost disposable cameras that are waterproof are recommended,
particularly given the defined cap of images making data and costs more manageable.
Ethical approval should be obtained from a competent organisation/institution and
full consent must be obtained from participants.
Stage 3. Recruitment and training: Participants should be recruited via a training workshop. As a rule of thumb, Wang and Burris (1997) recommend to recruit a group of 7 to
10 people to participate in the Photovoice method via a combination of snowball and purposive sampling. Purposive sampling is a form of nonprobability sampling that allows for
the selection of individuals based upon a variety of criteria determined by the research
study of interest. Snowball sampling is a nonprobability sampling process that is used to
identify research subjects through an initial contact who suggests possible participants for
the study. A mix of male and female participants should be recruited to allow for effective
gender analysis. Once participants have agreed to participate in the study, a group training session (estimated 2 h) should be organised and cover (1) research aims, timeline,
and benefits of participation; (2) ethical considerations in research using photography; (3)
safety concerns; (4) technical instructions regarding how to use the disposable cameras;
and (5) details of the camera assignment. Informed consent should be obtained from all
participants, verbally via use of a Dictaphone or in writing. In the context of small-scale
fisheries, training may be facilitated by a translator, and in these situations, it is recommended that guidance be provided to the translator in advance of the workshop. Instructions should be presented orally and/or with visual aids such as a leaflet to help guide potential illiterate or vulnerable older/younger participants. A dummy camera can be used
to help instruct participants on how to use the camera. At the end of the training session,
each participant should be given a camera with a unique tag ID for data ownership control.
The camera assignment stage is flexible and participants should be asked to take pictures
in accordance with questions that reflect the aims of the project. Within the context of this
review, the following questions were proposed for the context of small-scale fisheries to
obtain deeper insights into the fisheries socioecological aspects:
Box continues
simmance et al.
84
Box 1. Continued
1. What activities do you carry out in relation to fish farming or capture fisheries?
2. What benefits do you receive from fish farming or capture fisheries?
3. What challenges do you experience in fish farming or capture fisheries?
Stage 4. Photography assignment and collection: Participants are to be left with one
camera each for a recommended period of 1 week. During this time, researchers should
periodically check in on participants to ensure that cameras have not been stolen or
damaged and that participants are content with the task (either via telephone or face to
face). After 1 week, cameras should be collected and developed at a local photography
store.
Stage 5. Discuss photographs through individual interviews: After the photographs
have been printed, in-depth individual interviews should be conducted to learn the narratives behind photographs. Interviews should be recorded with permission for further
analysis and to allow cross-checking of narratives. During discussions, printed photographs should be displayed and a subset of the most important pictures should be selected by the participant in accordance with each of the three research questions posed.
A variety of techniques can then be used to elicit responses to questions about the photographs and to learn the narratives behind the photographs (Palibrodo et al. 2009).
Researchers can choose a technique that best fits their project. Within the context of this
review, a modified version of Wang et al.’s (1998) mnemonic SHOWED line of questioning was developed as follows:
1. What is in the picture?
2. Why did you take the picture?
3. Why did you select this picture over the others?
4. What would you like to tell to others with this picture?
5. Why would it be important to give this message to others?
6. Is there any other information you were unable to capture during the exercise that you
would like to share?
The length of the interview will be subject to group size and it is recommended that the
researcher sets aside a minimum of 3 hours.
Stage 6. Data analysis: Transcript data obtained from individual interviews can be analysed in a similar way to other qualitative data, via codifying, and exploring, formulating,
and interpreting themes. To minimize the time required from participants and expenses
incurred from site visits, this review recommends analysis to be carried out by the researcher and later verified by participants in stage 7.
Stage 7. Presentation of findings and discussion of outcomes: The aims of the final
group session should be to (1) share narratives and verify key messages, (2) discuss dissemination activities, and (3) capture group perspective on the Photovoice experience.
The group interviews should be recorded with permission to assist further analysis. This
stage is flexible and should be tailored to meet goals of a given project.

85
Box 1. Continued
Stage 8. Dissemination: Many projects have included an action phase to share their
photographs and findings via the development of books, exhibitions, targeted workshops or forums for broader community and policy awareness. This emphasis on involving policymakers and broader community activities has been a part of Wang et al.’s
(1997) recommendations for best practices. This stage is flexible and should be driven
by outcomes from stage 7, as well as the goals of a given project.

Abstract.—The biological assessment of inland waters using ecological criteria
is becoming more important due to the need to evaluate and monitor aquatic environments that are under heavy environmental stress. Turkey has been trying to
develop a model to understand its inland waters in terms of the European Water
Framework Directive’s (WFD) European fish index (EFI). The EFI is derived from
assessment of five biological elements. The EFI is inappropriate for the conditions in
Turkish inland waters; thus, the present study developed a fish-based index of biotic
integrity for Turkey (FIBI-TR) as a suggestion. To assess the adequacy of the FIBI-TR,
this study gathers field data in two selected basins in 2013 and 2014 according to
WFD criteria for biological elements and physicochemical parameters, simultaneously. The FIBI-TR was then compared to the scores derived from the WFD score,
which was a cumulative score for all related biological elements, and with other frequently used indices such as the Water Pollution Control Directive and trophic state
index. Based on these data, the FIBI-TR seems to be congruent with cumulative WFD
scores. However, the FIBI-TR does not agree with other indices based on physicochemical parameters. Detailed research is needed if WFD is to be adapted for Turkey
through FIBI-TR.
Introduction
Turkey has been implementing the Water
Framework Directive (WFD) as part of a process to apply the European Union’s directives
for eventual membership. First attempts in
implementing this directive go back to 2002
when a preliminary project was conducted
in cooperation with Netherlands, France, and

Spain. Since then, monitoring of several basins had been completed while many projects
supported by the Republic of Turkey Ministry
of Forestry and Water Affairs, General Directorate of Water Management are still ongoing
(Alka 2013a, 2013b; Cınar 2013a, 2013b; Artek
2015a, 2015b, 2015c; Segal 2015a, 2015b).
Assessment of the ecological status of
inland waters consists of five biological elements: fish, benthic invertebrates, phytoplank-
92
yerli et al.
ton, phytobenthos, and macrophytes. Among
these, fish fauna assessment is relatively easy
(sampling, identification, etc.) and is highly indicative of any ecological degradation. For this
purpose, a European fish index (EFI) was developed as an output of the Fame and EFI+ projects (Fame Consortium 2004; EFI+ Consortium
2009). It is impossible for Turkey to implement
EFI, which is shared by several European countries, because it is not a partner of the FAME
project and the related ecoregion is not defined.
In order to develop a regional index, a typology
of the water resources was defined and its faunal composition is under investigation.
The aim of this study is to develop a
fish-based index of biotic integrity for Turkey (FIBI-TR), with metrics based on Karr
(1981), and to evaluate its assessment capability. For this purpose, calculated FIBI-TR
scores are first compared with the cumulative WFD score acquired by assessment of the
five biological elements. All related biological
elements (macroinvertebrates, fish, phytoplankton, phytobenthos, and macrophytes)
were assessed for each locality and a final
WFD score was determined according to the
“one-out, all-out” principle and the arithmetic mean of the scores of these biological elements. Second, the FIBI-TR score is compared
with other frequently used indices, such as
Figure 1.—Selected basins for the sampling.
the Water Pollution Control Directive water
quality classes (WPCD 2004) and the trophic
state index (Carlson 1977) in order to demonstrate their similarities and differences.
Methods
Field studies were conducted in May 2013 for
the Akarçay basin (AB) and in May 2014 for the
Küçük Menderes basin (KM) (Figure 1). Sampling of biological elements was conducted simultaneously with that of the physicochemical
parameters of the water column (Alka 2013a;
Segal 2015a).
Fish sampling was conducted according
to WFD criteria, using electrofishing in rivers
(CEN 2003a) and with multi-mesh gill nets
in lakes (CEN 2003b). In lake sampling, some
minor adjustments were made based on the
European Standard EN 14757. These adjustments reduce the number of multi-mesh gill
nets in order to avoid pressure on protected
species, using larger mesh sizes (70, 90, and
110 mm) for catching large water column species and using fyke nets for catching the large
benthic fish species, which were unable to be
caught with multi-mesh nets according to EN
14962 (CEN 2003c; Šmejkal et al. 2015).
Ten sampling localities were selected
where there was enough preexisting data
fish-based index of biotic integrity for turkish inland waters
about the fish fauna. Anthropogenic effects and
reference conditions were taken into account
while selecting the localities.
The FIBI-TR developed is a multimetric index based on reference condition criteria and
was calculated as described by Karr (1981),
Karr et al. (1986), and Kestemont and Goffaux
(2002). Thirteen metrics were defined and
each was given points from 1 (worst ecological
condition) to 5 (best ecological condition). The
FIBI-TR metrics and their expected impacts are
summarized in Table 1.
All metric scores are summed into cumulative FIBI-TR score by locality. These scores and
their corresponding ecological statuses are
given in Table 2. For comparison with other indices, FIBI-TR scores are classified from 1 (bad
ecological status) to 5 (corresponding to a very
good ecological status).
Four parameters that are related to the trophic state of the water column (dissolved oxygen, pH, total phosphorus, and total nitrogen)
were selected from Water Pollution Control
Directorate (WPCD) water quality classes, and
sampling stations were classified according to
the values given in Table 3. Values range from
1 to 4, with class 1 representing the best water quality and class 4 representing the worst.
Sampling localities were classified according
to the “one-out, all-out” principle (i.e., the wa-
93
ter body’s final ecological status is determined
by the worst scored biological element) for
comparison with WFD scores.
Trophic state index (TSI; Carlson 1977);
TSI Secchi depth, and TSI total phosphorus
were calculated according to simplified equations given below (Carlson and Simpson 1996).
Trophic state index values then turned to quality evaluation values as described by Sulis et al.
2014.
TSISecchi depth = 60 – 14.41 lnSecchi depth
TSITotal phosphorus = 14.42 lnTotal phosphorus + 4.15
FIBI-TR, WPCD water quality classes, TSI
values, and WFD results were calculated using
the same database.
Results
Results obtained from field studies in the Akarçay (Alka 2013a) and Küçük Menderes (Segal
2015a) basins are summarized in Table 4.
Water Framework Directive results are given
in the first three columns. The WFD column
represents the status of the locality according
to the “one-out, all-out” principle, whereas the
mean column is the arithmetic mean of values
of all five (or four, depending on sampling site)
biological elements.

with each other. When we compare these two
parameters (TP and TKN), there are inconsistencies between the WFD and FIBI-TR scores.
Localities like Lake AB01, Stream KM01, and
Stream KM02 show similar TP and TKN scores,
indicating bad quality (3–4), whereas their
WFD and FIBI-TR scores vary from bad quality
to good (1–4).
Trophic state index results for Lake KM1,
Lake KM2, Lake KM3, and Lake AB1 agree
relatively well with FIBI-TR. Trophic state index assessments appear more reasonable than
WPCD to evaluate these lake ecosystems.
There seem to be some similarities between WPCD and TSI values. Sample size was
not large enough for a clear statistical evaluation for this assessment; however, the tendency of these indices to support each other
seems promising. As a result, the FIBI-TR developed seems to be in agreement with the
cumulative WFD score but disagrees with the
TSI and WPCD indices, which are based on
physicochemical parameters. However, as the
database grows, we believe parameters listed
under these indices can be incorporated into
the FIBI-TR.
WFD ecological status
Bad (1)
Weak (2)
Fair (3)
Good (4)
Very good (5)
Comparisons between WFD and FIBI-TR
scores were made using the arithmetic mean
of biological elements because when the “oneout, all-out” principle is applied, single biological element can cause the ecological status of
the water body to decrease dramatically. One
example is Streams AB1 and AB3 where the
FIBI-TR suggests a fair (3) status whereas the
WFD score suggests a poor (1) ecological situation. For these localities, the mean value of all
biological elements is classified as weak (2),
although many of the biological elements have
better ecological statuses.
WFD-mean, which is the mean of all biological element index results, and FIBI-TR scores
for two of the lakes are identical, whereas two
of them (Lake AB01 and Lake KM02) differ by
one degree. Similarly, WFD-mean and FIBI-TR
scores for three of the streams are identical,
whereas Streams AB01, AB03, and AB04 differ by one degree. FIBI-TR scores for Streams
AB01 and AB03 suggest a better ecological status (fair), whereas the WFD-mean scores represent a poor status.
Within WPCD, dissolved oxygen and pH
results are not consistent with phosphorus
and nitrogen parameters. However, results
for the latter, total phosphorus (TP) and total
kjeldahl nitrogen (TKN), seem to be consistent
Discussion
The WFD’s EFI is shared by many countries;
however, due to adaptation problems, some
Mediterranean countries are unable to use it.
Therefore, the index of biotic integrity of Catalonia (IBICAT) has been developed for Catalonia in Spain (Sostoa et al. 2004, cited by Segurado et al. 2014); IBI-Jucar has been developed
for the Jucar River basin in Spain (Aparicio et
al. 2011); two separate indices have been developed for the Guadiana basin, one for Portugal (Magalhães et al. 2008) and the other for

Spain (Hermoso et al. 2010); and F-IBIP has
been developed for Portugal (INAG and AFN
2012, cited by Segurado et al. 2014). All these
indices have been improved to solve application problems of the WFD’s EFI. Implementation of the EFI in Turkey is also problematic,
experiencing problems similar to those these
in other Mediterranean countries. Turkey has
a high diversity of fish and habitats and a high
number of endemic fish species (Kuru et al.
2014). The EFI+ was developed for 15 European countries (EFI+ Consortium 2009) and
did not consider other countries, and also their
ecoregions, in Europe, such as Turkey.
The WFD can be adapted for Turkey
through FIBI-TR; however, the application of
the FIBI-TR must address some challenges that
are described below along with some possible
solutions.
1.
Turkey’s inland water resources vary
greatly in terms of water quality, trophic
status, typology, altitude, climate, ecosystem diversity, and species diversity. A total
of 25 basins, including many subbasins
with different biogeographical histories,
have been identified. A reference condition criteria needs to be applied separately
for each basin, such as those presented

here for the Akarçay and Küçük Menderes
basins. All the efforts concerning FIBI-TR
need to be followed by a national calibration process.
Long-term historical data are insufficient
or are not available in many inland water
basins, especially for fish species. The literature on the fish fauna generally lacks
information on geological position, and
this needs to be determined and digitized.
Because there is no detailed fish distribution database and bioecological information of the fish species is generally lacking,
especially for endemic species, reference
conditions are hypothetical. Bioecological information about these species, which
are needed for the metrics, needs to be determined and published as soon as possible.
Fish, which represent the top level of the
aquatic trophic chain and thus have the
potential of integrative indication of biological change, also show a wide range of
responses to different impacts. But individual and population based responses
of fish to these impacts has still not been
assessed. Thus, in order to determine the
effects of aquatic degradation on the Turk-
96
yerli et al.
ish fish fauna, studies should include detailed physicochemical parameters.
This research is one of the earliest contributions to the development of a fish-based index for Turkey and it will need to be improved.
More detailed research is needed to develop a
synthesis and to understand WFD implementation for Turkey.

Assessing Inland Fisheries: What Can Be Learned
from Australia’s Murray–Darling Basin?

Abstract.—The collection and use of data to manage the freshwater fisheries of
Australia’s Murray–Darling basin (MDB) has a poor history of success. While there
was limited assessment data for early subsistence and commercial fisheries, even
after more robust data became available during the 1950s its quality varied across
jurisdictions and was often poorly collated, assessments were not completed, and
the data were underutilized by management. The fishery for Murray Cod Maccullochella peelii is given as an example, where the fishery declined to the point of closure and then the decline continued to the extent that Murray Cod was listed as a
threatened species and all harvest now only occurs through the recreational fishery.
Lessons from such poor population assessments have not been fully learned, however, as there remains a paucity of harvest data for this recreational fishery. Without
a proper assessment, a true economic valuation of this fishery has not been made.
As the MDB is Australia’s food bowl, there are competing demands for water use
by agriculture, and without a proper assessment of the worth of the fishery, it is
difficult for Murray Cod to be truly considered in either economic or sociopolitical discussions. The poor state of MDB rivers and their fish populations (including
Murray Cod) has, however, resulted in political pressure for the development of the
sustainable rivers audit, a common assessment method for riverine environmental
condition monitoring. This audit undertakes standardized sampling for fish and a
range of other variables at a number of fixed and randomly selected sites on a 3-year
rotating basis. While the sustainable rivers audit has provided a range of data indicating that the condition of rivers is generally very poor, these data have yet to be
fully utilized to determine the potential state of the fisheries (such as Murray Cod)
or to set targets for rehabilitation, such as for environmental flows. While, to date,
data analyses have been somewhat restricted by fiscal constraints, more comprehensive use of data, together with full fishery valuations, should be seen as the way
forward for improved management.
Introduction
Adequate assessments of data are essential for
science-based fisheries management to inform
management objectives; to maximize outputs,
cost-effectiveness, and the longevity and sustainability of the fishery; and to reduce the risk
of stock collapse. Without adequate assessments, the true value (total, not just economic

value) of some fisheries may be severely underestimated or, indeed, not recognized at all
(FAO and World Fish Center 2008; Kang et al.
2009). This may compromise the future prospects for fishery stocks, especially when decisions are being made about resource trade-offs
that may affect them, such as water extraction
for irrigation or hydopower (Allan et al. 2005).
The different and disparate nature of inland
fish and fisheries pose many difficulties for
their assessment, with the collection of data

recognized as particularly difficult for smallscale fisheries (Andrew et al. 2007). Such assessments are also often exacerbated by a lack
of fiscal resources, particularly in rural areas
and poorer nations (FAO and World Fish Center 2008). Proper assessments of inland fisheries, however, are also not always undertaken in
developed nations, where resources are more
plentiful, and the economic value of some commercial and recreational fisheries are also not
always being fully accounted for (Cooke and
Cowx 2006).
This paper provides a case study where
the inadequate collection, analysis, and application of fishery assessment data to properly
manage the commercial Murray Cod Maccullochella peelii fishery in the Murray–Darling basin (MDB), southeastern Australia, ultimately
led to its closure. It suggests a way forward to
manage the recreational fishery for this species
into the future and also provides the example
of a new assessment method for riverine envi-
ronmental condition monitoring, the sustainable rivers audit, which may have applicability
to other river systems.
Background
Australia is the driest inhabited continent
(area 7.6 million km2), with Aboriginal occupation dating back 60,000 years and European settlement occurring only 240 years
ago. With a population of 23 million, Australia
is highly urbanized, mostly settled along the
eastern coast (Figure 1); it is governed by a
national and eight state and territory jurisdictions. It is a developed nation with a relatively
high gross domestic product (2013: per capita Aus$67,100; http://dfat.gov.au/about-australia/Pages/about-australia.aspx). The MDB
(Figure 1) occupies about one-seventh of
the continent (more than 1 million km2) and
was settled post-1830s. It contains 2 million
people and has six partner jurisdictional gov-

ernments. Agriculture occupies 84% of MDB,
contributes 39% of the nation’s agricultural
production with a value of approximately $15
× 106 per annum (2005–2006; ABS 2012) and
accounts for 50% of the nation’s irrigated agricultural water use (2007–2008; Koehn 2015).
The concentration of agricultural development, most of which occurred post World War
II (Figure 2) has resulted in significant ecological pressure on aquatic systems, with high levels of flow regulation, water abstraction, and
floodplain and riparian modification (Murray–
Darling Basin Commission 2004). This has led
to concerns about overallocation of water (Lester et al. 2011), which were highlighted by the
Millennium Drought (1997–2010; Murphy and
Timbal 2008), which greatly impacted both irrigated agricultural production and environmental assets (Kingsford et al. 2011).
A range of reforms, including the Basin
Plan have been initiated to address the need
for complimentary management of water
across the competing demands of irrigation
and the environment with the aim to allocate
101
increased amounts of water to improve riverine environments (Murray–Darling Basin Authority 2011). The Basin Plan has proven to be
one of the most controversial reforms of natural resource management in Australia’s history, generating high levels of political debate
and public protest from regional irrigators as it
aimed to reduce the consumptive use of water
by up to 4,000 GL/year at an estimated cost of
$3.1 × 106 (Koehn 2015).
The MDB has a limited native fish fauna
of only 44 naturally occurring species (Lintermans 2007), which are impacted by a range
of threats (Cadwallader 1978; Murray–Darling
Basin Commission 2004). Native fish have suffered serious declines, and overall, populations
are estimated to be now at about 10% of their
pre-European settlement levels, with many
localized extinctions, many species of conservation concern, declines in flagship species,
and concerns about declines in recreational
angling success (Koehn and Lintermans 2012).
Definitive assessments of these populations
was difficult, however, as there are few con-

sistent, quantitative data available on species’
population status (e.g., Cadwallader 1977; Cadwallader and Gooley 1984). Most assessment
data comes from commercial fishery market
documents, which are only available for a few
species (Kailola et al. 1993) and have a lack of
consistency across species and jurisdictions,
which has greatly hampered the analyses of
population trends and status (e.g., Forsyth et
al. 2013; Ye et al. 2014).
Native fishes of the MDB were harvested
only for subsistence by native Aboriginal tribes
(Dargin 1976) until after the mid-1800s when
more wide-scale commercial fisheries were introduced (Figure 2). These commercial fisheries expanded rapidly, concentrating on a few,
larger species. One of the most popular species
was the large Murray Cod (see Rowland 1989,
2005; Lintermans 2007), which is distributed
throughout most of the MDB. Initially, there
was limited market data for this fishery, but by
the early 1900s there were already concerns
about potentially unsustainable catch rates
(Dakin and Kesteven 1938; Figure 2). Even after considerable market catch data were available (1950s), their quality varied across jurisdictions and they were often poorly collated
and therefore had limited use by management.
Commercial fishery data from the state of New
South Wales showed a rapid decline in Mur-
ray Cod after 1960 (Figure 3; Reid et al. 1997),
and this fishery was closed in September 2001.
Other jurisdictional fisheries for Murray Cod
were also closed, with all harvest now only
undertaken through the recreational fishery.
The decline of Murray Cod was such that it was
listed nationally as a threatened species (International Union for Conservation of Nature
vulnerable category) in 2003 (Department of
the Environment and Heritage). Even today, for
this threatened and important species, limited
utilization of data for management continues,
with a paucity of assessment data for the recreational fishery harvest. In a recent attempt
at stock status assessment, Murray Cod was
deemed to have undefined stock status in all
jurisdictions due to a lack of data (Ye et al.
2014). A true assessment of harvest by the recreational fishery has not been quantified, and
an economic valuation of this fishery has also
not yet been made (Ernst and Young 2011).
The Sustainable Rivers Audit
The decline of the Murray Cod fishery, together
with other environmental factors, highlighted
the poor state of MDB rivers and provided political pressure for the development of the sustainable rivers audit (SRA). The SRA provides
a dedicated assessment method for environ-

mental condition monitoring. Previously, any
management assessments were made from
disparate, ad hoc data collections. This audit
undertakes standardized sampling for fish and
the collection of a range of other variables on
a rotating basis (every 3 years; Davies et al.
2012). This fish community sampling includes
all species and is undertaken in rivers (not
lakes or wetlands), using standard methods,
by all jurisdictions across the MDB. This fish
community approach, together with the collection of other variables, has differences to many
traditional stock assessments. For example,
historical records were used to develop a list
of species that would have been expected to
occur at each sampling site. There were some
challenges to transferring from an ad hoc to a
standardized approach, with considerable resources allocated to consultative workshops,
method development, and training. Sampling
sites are randomly selected in montane, upland, slopes, and lowland zones, with the data
being compiled to produce a series of indices
and end of valley scores. Fish sampling methods include electrofishing (boat; 12 × 90 s ontime or backpack; 8 × 150 s on-time), and bait
traps (unbaited, unlighted; 90–150 min)
These measures are amalgamated into a
series of fish metrics: expectedness (species
observed: species expected from historical
records); nativeness (natives: aliens), species’
103
abundance and biomass, recruitment (index
of juvenile fish indicating recruitment), and an
overall fish index. Data on supplementary variables, such as water temperature, conductivity,
turbidity, depth, width, and woody habitat, are
also collected (see Davies et al. 2012).
Results from the 2005–2007 sampling
confirmed the concern about the health of rivers in the MDB with 19 of 23 river valleys rated
in “poor” to “extremely poor” ecological condition (Davies et al. 2010; Figure 4). These data
were collated from sampling undertaken at 487
sites (23 valleys), catching 60,600 fish (4 metric tons). Expected species were only caught at
41% of sites. Similar data were obtained from
the following cycle of sampling (2008–2010;
Davies et al. 2012). Such sampling, however, is
very intensive and had an annual cost of about
$1.2 × 106. While the SRA has provided a range
of data indicating that river conditions, in general are very poor, it has yet to be fully utilized
to determine the potential state of the fisheries
such as Murray Cod.
Discussion
Historically, there has been a lack of data collection, collation, analysis, and use to inform
fisheries management in the MDB. This has
contributed to the decline in populations of
Murray Cod, the major commercial and angling

species, to the point where it now has threatened species status and a national recovery
plan has been prepared (National Murray Cod
Recovery Team 2010). The lack of a stock status (Ye et al. 2014); recreational fishery harvest assessments; especially on a catchment
or regional basis (Henry and Lyle 2003); and
quantitative economic valuations of the fishery
(Ernst and Young 2011) mean that Murray Cod
has largely been ignored in the water-reform
debates for the MDB (Koehn 2015). In separate
analyses, an initial assessment of the economic contribution of recreational angling to the
MDB suggested likely estimates of $1.35 × 109
direct expenditure; $357 × 106 added expenditure; a $403 × 106 contribution to gross domestic product; and a contribution of 10,950
jobs (Ernst and Young 2011). In addition to
these economic evaluations, the public clearly
realizes that other social and cultural values of
fishes (Ginns 2012) should be recognized as
a way to illustrate benefits of the Basin Plan
(Koehn 2015).
Historically, data have only been available
for a few, large MDB fish species, and consistency in collection, collation, and availability
has been variable across jurisdictions. The instigation of a more comprehensive assessment
of fishes has occurred only after the Murray
Cod fishery had declined. The Sustainable
Rivers Audit provides a comprehensive data
set for the assessment of river condition that
comprises a set of agreed measures, including
fish populations, that has greater scientific
rigor and acceptability among jurisdictions
and their management agencies. While this
type of assessment may differ from true fisheries stock assessments, it does provide widespread, consistent data that can be further
mined and added to. For example, data trends
over time (especially long term) will provide
baselines from which the recovery of species
(Koehn et al. 2013) or rehabilitation of the native fish community (Koehn and Lintermans
2012) can be measured and rehabilitation
targets set. This is especially important for
the provision of environmental flows (Koehn
et al. 2014; Koehn 2015). Additional information such as catch detection rates (Lyon et al.
2014) and recreational harvest may be incor-
porated with SRA data to help more accurately
reflect true population levels. Such assessments can also inform population models that
allow management to be more predictive in
its outlook by testing the potential outcomes
for different management options (Koehn and
Todd 2012).
Despite not having many of the constraints
of small-scale, subsistence fisheries in poor, developing countries, the example of the Murray
Cod fishery of the MDB also highlights that lack
of proper fisheries assessment data and their
use can also occur in developed nations, to the
great detriment of the fish and fishery. While
the Sustainable Rivers Audit has provided a
comprehensive environmental monitoring program, collecting a range of data on river conditions, these data have yet to be fully utilized to
determine the potential state of the fisheries
or to set targets for their rehabilitation (such
as for environmental flows; Koehn et al. 2014;
Koehn 2015). While, to date, data analyses has
been somewhat restricted by fiscal constraints,
further use of the data by a range of agencies, together with fisheries valuations, should be seen
as the way forward should be utilized to better
manage the fisheries.

Abstract.—Inland fisheries provide important contributions to human well-being, but these contributions are often overlooked or undervalued by decision makers. Consequently, inland fisheries are not adequately considered in either global
fisheries sustainability initiatives—which are generally marine-focused—or in the
use of freshwater resource planning in an era of water crisis. Here we synthesize
the state of knowledge of the contribution of inland freshwater fisheries to human
well-being. To date, there has been no coordinated global valuation of the ecosystem
service contributions of inland fisheries, and it is thus only possible to highlight the
range of services they provide from isolated case studies. Throughout these studies,
human nutrition emerges as a key value, with freshwater fish providing essential
nutrients in countries such as Cambodia and Bangladesh, which are endowed with
productive freshwater fisheries. Inland fisheries also provide livelihoods, income,
economic autonomy, dietary diversity, cultural identity, and social structure to tens
of millions of people around the world. The diversity of fishing methods, conservation strategies, and traditional ways of managing fisheries enriches the human
experience and represents a source of cultural and technical knowledge and human
institutional ingenuity. In this paper, we review what is known about approaches for
assigning values to freshwater fisheries and identify methods to better assess and
communicate those values to decision makers and the public in order to increase
representation of inland fisheries in natural resource decision-making processes.
Most importantly, we focus on the contributions of inland fisheries to food security,
nutrition, community cohesion, and improved livelihoods. This paper also explores
approaches that consider the knowledge and perspective of fishers, fish workers,
other aquatic resource users, and their communities to augment and improve the
knowledge and perspective of scientists and resource managers in better managing freshwater fisheries resources. We also stress the importance of ensuring that
assessments explicitly consider gender relations and roles in inland fisheries and
fishing-dependent societies. Better recognition and valuation of the economic, nutrition, and social benefits that inland fisheries provide to human communities is
an essential step toward better incorporating inland fisheries into future water and
food security policies.
Introduction
The vast majority of global inland fisheries
catch is used for direct human consumption
(Welcomme et al. 2010). These important and
productive food resources, however, are often
negatively impacted because decisions about
the allocation and management of inland waters often either ignore or do not include an
accurate assessment of the economic, soci-
etal, and cultural values that inland fisheries
contribute to society (Bartley et al 2016, this
volume). This exclusion from decision-making
processes partially occurs because information about the valuable contributions of inland
fisheries to economic, social, and individual
well-being is not well documented or effectively communicated, especially to policymakers. Although a few case studies exist (Béné
unappreciated livelihood contributions of inland fisheries
and Neiland 2003; Baran et al. 2007; Navy
and Bhattarai 2009), no global assessment of
the value of inland fisheries has yet been conducted. In instances where there is some estimate of the monetary value of these fisheries
(usually in terms of fishing income and profits or license and tax revenues), economic assessments have often ignored the important
contribution of freshwater resources to nutrition, health, livelihoods, leisure, individual
and societal well-being, as well as the values
associated with religious and cultural uses of
freshwater resources (UNEP 2010; Welcomme
et al. 2010). This incomplete portrayal of inland fisheries contributions lessens their value
and importance to decision makers, especially
those more distant from the local communities where the fish are captured. The absence
of inland fisheries from the decision-making
process is also partially due to the inaccuracies
and uncertainties surrounding current inland
fisheries assessment and reporting (Cooke et
al. 2016; Lymer et al. 2016a; both this volume).
In assessing the overall values of inland
fisheries, it is essential to focus on both the
ecosystem services (e.g., habitat, freshwater,
fish, and biodiversity) and the flows to the social and economic sectors (e.g., fishers, processors, and others involved in inland fisheries)
that are involved in inland fisheries. To ensure that each of these components are given
proper consideration when assessing the value
of inland fisheries to human societies, a conceptual framework capable of articulating the
various services provided by inland fisheries
and methods of how to best to assess these
contributions is required. Smith et al. (2013)
suggests a framework for linking general economic, social, and ecosystem goods and services to human well-being. The framework
has nine domains of well-being: health, social
cohesion, education, safety and security, living
standards, spiritual and cultural fulfillment,
life satisfaction and happiness, leisure time,
and connection to nature. We have adapted
this framework into a fisheries context to illustrate its utility in linking the economic, social,
and ecosystem goods and services provided by
inland fish and fisheries to human well-being
(Lynch et al. 2016b; Figure 1).
109
Each of the nine domains of well-being is
important to gain a full understanding of the
role and importance of inland fisheries to economic, societal, and environmental well-being,
which combine to describe overall human and
societal well-being. These nine domains relate
to inland fish in many ways:
•
•
•
•
•
•
In the context of inland fisheries, the domain of health focuses on outcomes of personal well-being, life expectancy and mortality, and physical and mental health conditions from reliance on inland fisheries
for nutrition, including micronutrients
during the first months of life from conception to 24 months.
The domain of social cohesion focuses on
outcomes such as identity, family demographics, and social norms, stemming
from social network ties among individuals and within communities, enhancing
the quality of life for those dependent
upon inland fisheries.
The domain of education focuses on outcomes derived from formal and informal
education and skills transfer, which enhance basic capabilities that lead to the
expansion of other capabilities necessary
for well-being development. In the context
of inland fisheries, education capabilities
are an antecedent to the ability to adjust
effectively to market or technology changes.
The domain of safety and security focuses
on outcomes related to overall freedom
from harm, promoting personal physical
security, national security, and financial
security. In our context, reliance on inland
fisheries can promote financial security,
especially for women or children, by providing for enhanced livelihoods and income.
While the domain of living standards is
largely economic in nature, this domain
focuses on outcomes related to income,
living conditions, home ownership, and
household assets accessible as a result of
inland fisheries activities.
Cultural values of inland fish or symbolism
related to fish may promote the domain

provided by inland fish and fisheries to human well-being. (Adapted from Smith et al. 2013).
•
of spiritual and cultural fulfillment, which
focuses on outcomes related to interconnections between one’s self and others
and the environment as a result of access
to religious activities, cultural interests
and identity, and a connection to nature.
The domain of life satisfaction and happiness focuses on outcomes related to self-
reported happiness and whole-life satisfaction. Life satisfaction and happiness
with inland fisheries in the developed
world may occur at higher rates than in the
developed world, in part because life satisfaction tends to plateau in the wealthier,
developed world. Perhaps more appropriate to the developed world than the devel-
unappreciated livelihood contributions of inland fisheries
•
oping world, inland fisheries may be a focus of pleasurable activities that people
are able to engage in outside of their work
or other responsibilities (e.g., fishing, fish
ing clubs), resulting in outcomes in the domain of leisure time.
The domain of connection to nature focuses on outcomes related to biophilia—
an emotional attachment of human beings to other living organisms (Wilson
1984; Smith et al. 2013). Measures of
biophilia can describe the connection
people have with inland fisheries or their
ecosystem services. In the developing
world, the relationship among humans,
inland fisheries, and their ecosystem services may be curvilinear. People in the developing world likely have strong biophil
ia; as their livelihood dependence on in
land fisheries wanes so too does biophilia,
until individuals rely again on inland fisheries for other reasons such as leisure
time.
While the human well-being framework
depicted in Figure 1 may be appropriate for a
global context, it is essential to clarify which
domains are more appropriate for inland fisheries in a developing context than in a developed
context, and vice versa. A holistic framework,
one that incorporates gender roles, power dynamics, and political ecology, will be more effective for valuing, and in the valuation of, inland
fisheries to society. Further, when methods and
metrics are solidified and implemented to value the social, economic, and ecosystem goods
and services provided by inland fisheries, their
contributions become even more prominent in
society. However, some challenges exist in the
determination of the value of inland fisheries, as
discussed in the next section.
Challenges associated with valuing inland
isheries
It is difficult to accurately assign a monetary value to inland fisheries because they are complex,
and geographically diffuse and occur largely
outside formalized markets (Welcomme et al.
2010). Harvest and use (e.g., consumption, recreation, and livelihood) statistics, particularly in
111
the developing world, are often unavailable or
inaccurate (Welcomme 2011). Many areas lack
the infrastructure, labor force, or capital needed
to generate harvest estimates and check the accuracy of existing estimates (Welcomme 2011).
Additionally, because many inland fisheries are
so diffuse, many agencies opt to collect data only
on larger-scale commercial fisheries and report
little or no data on others (e.g., subsistence fisheries, recreational fisheries; FAO 2003; Kang
et al. 2009). The livelihood and food security
benefits provided by inland fisheries are also
difficult to measure since many inland fisheries
are subsistence based and thus occur outside of
formal markets, rendering the value of most inland fish transactions invisible to normal channels of data collection on economics (Bartley et
al. 2015). Some methods, such as indirect-use
valuation and the travel-cost method, have been
applied to inland fisheries in the Mekong basin
(Baran et al. 2007) and the Copper River in Alaska (Henderson et al. 1999). In general, however,
very few valuation studies have been done of
subsistence inland fisheries.
Compounding the difficulties of valuing
inland fisheries are the challenges associated
with valuing freshwater ecosystems in general and the impact that external drivers (e.g.,
changes in land use, climate change) have on
inland fisheries (Brummett et al. 2013). The
complex interactions of climate, water, and
land use challenge creation of projections of
the impacts that climate change will have on inland fish and those who rely on them (Lynch et
al. 2015). Illegal and destructive fishing methods, coupled with inadequate enforcement of
fishing regulations, complicate assessment of
inland fisheries and further challenge the assessment of actual catches (Allan et al. 2005).
Improved low-cost approaches for estimating
fish harvests and methods to trace flows of
inland fish through ecological and human systems would help to reveal the largely invisible
values of inland fisheries.
The contribution of inland isheries to health
and food security
Food and nutrition security is one of the most
important ecosystem goods and services pro-
112
youn et al.
vided by inland fisheries, the majority of which
are used for direct human consumption (Youn
et al. 2014). It is generally accepted that direct
consumption of inland fish plays an important
role in the diets of many population groups,
particularly in the developing world (Roos
2016; Funge-Smith 2016; Lymer et al. 2016b;
all this volume). Exploring and supporting this
generalization, however, is very difficult due to
lack of reliable data on direct human consumption, indirect human consumption (e.g., use
of inland fish in animal feeds), and nutrients
present in inland fish (Welcomme 2011; FAO
2014; Bartley et al. 2015).
Freshwater ecosystems and the inland
fisheries they support are diverse and can have
high productivity of fish and other aquatic species that feature in people’s diets or can be
sold to support food and livelihood security
(Dudgeon 2000; Kang et al. 2009). This diversity of inland aquatic organisms, especially the
smaller fish species, is an important nutrition
source for human communities. All fish species
are a rich source of animal protein (Beveridge
et al. 2013). Additionally, small fish, which are
eaten whole (bones, organs, and head), contribute essential minerals and vitamins, such
as calcium, phosphorus, zinc, iron, and vitamin
A, to the human diet (Roos et al. 2003). Due to
their size, it is often difficult to consume large
fish whole, and thus, large fish do not provide
these same nutrients. The micronutrients provided by freshwater fish are often inaccessible
to local communities in other forms, either due
to price or unavailability of substitutable food
sources that contain these nutrients.
Freshwater fish also have been reported to
enhance the bioavailability of micronutrients
from the other foods consumed during the
same meal since nutrients in the fish enhance
bioabsorption of nutrients present in the food
(Tontisirin et al. 2002). Micronutrient contributions from inland fish are especially vital
to economically disadvantaged people as they
tend to suffer disproportionately from micronutrient deficiencies, which have debilitating
effects on human nutrition, health, and survival, due to decreased access to nutrient-rich
foods (Fischer et al. 1999; Combs and Hassan
2005; Roos et al. 2007). Traditional knowl-
edge of local communities on the nutritional
and health attributes of many inland-capture
fish species also points toward the great value
given by these communities to inland fish and
people’s desire to ensure the continued use of
these fish as part of their families’ diets and
livelihoods (Roos et al. 2003).
Even though exact data regarding harvest, transactions, and consumption of fish
from inland fisheries are scarce, it is generally
accepted that inland fish contribute significantly to the consumption of animal-source
foods in rural populations in Africa and Asia,
especially during the peak fish-capture season
(Belton and Thilsted 2014). Fish consumption varies widely across countries, seasons,
and population groups, and there are very
little data for household fish use (e.g., different forms of consumption, bartering) beyond
national economic surveys. National data may
mask the critical contribution of inland fish
to the food security of a particular region or
population. Equally important, there is limited understanding of intra-household food
dynamics regarding the quantity and parts of
the fish that different members of the household consume. For instance, gender may be
an important aspect influencing consumption of inland fish within a household because
there is evidence from many countries that
females consume smaller portions of fish
and other animal-source foods compared to
males (Béné and Heck 2005; Kawarazuka and
Béné 2010). As a result women, compared to
men, often do not receive the same nutrient
and food benefits from inland fish, which can
exacerbate nutrient deficiencies in women,
particularly pregnant or lactating women.
In some cases, these are real differences due
to cultural factors, where males eat first and
have larger portions; elsewhere, this may be
due to reporting bias in the survey methodology (Gittelsohn 1991; Geheb et al. 2008). Real
differences in the amount of fish consumed
would affect household food security and the
nutrients each household member receives
from inland fish.
Another important aspect regarding consumption of fish is people’s access to markets
or other fish sources. Studies in Bangladesh
unappreciated livelihood contributions of inland fisheries
show that in communities close to water bodies with productive capture fisheries, only
one-third to one-fourth of fish consumed was
self-caught and the majority of fish consumed
was bought from nearby markets (Hels et
al. 2003), suggesting that local fisheries are
an important source for community food security. Again, gender and social roles are an
important aspect to consider as the power to
purchase fish, and thus access its nutritional
benefits, may not be realized equally among
different socioeconomic groups and within
households (Béné and Merten 2008; Belton
and Thilsted 2014).
In many areas, women and children take
part in capturing inland fish, and these fish
are generally used for household consumption (Bose et al. 2009). Infants and young
children can also significantly benefit from
consumption of inland fish (Roos 2016).
There is growing recognition of the positive
impact fish, via nutrients found in fish, can
have on growth, development and cognition
in infants and young children (Daniels et al.
2004). The role of essential fats, especially the
importance of omega-3 fatty acids for brain
development, is well known (Horrocks and
Yeo 1999; He et al. 2004), and some freshwater fish (e.g., Rainbow Trout Oncorhynchus
mykiss and Common Carp Cyprinus carpio;
Guler et al. 2008; Gogus and Smith 2010) have
high amounts of these nutrients. Studies on
developing fish-based products using small
indigenous species with high micronutrient
content have been conducted in Bangladesh,
Cambodia, and Kenya among pregnant and
lactating women and young children up to 24
months of age (Andersen et al. 2003; Longley
et al. 2014). These studies illustrate the important benefits that the nutrients in inland
fish provide to these vulnerable groups. The
first 24 months are considered the first 1,000
d of life, a window of opportunity for ensuring optimal child growth and development
that can lead to long-term optimal nutrition,
health, and development for the individual
child and better national and global development for society (Roos 2016). However, the
nutrient content of many inland fish species,
even frequently consumed fish species, is not
113
well known (Bogard et al. 2015) as nutritional profiles have tended to focus on larger
fish, typically from aquaculture, which may
have different nutrient profiles than wild
fish and fish on lower levels of the food web.
Determining the nutrient content of fish species and thus their contribution to nutrition
is an important first step to understanding,
analyzing, and promoting the present and future potential of inland fisheries to improve
global food and nutrition security (Roos et al.
2007).
Valuing the contribution of inland ish to
human society
Freshwater ecosystems support a diversity of
livelihoods and cultural values. For instance,
freshwater recreational fisheries in the United States are known to support more than
500,000 jobs generating more than US$30 ×
109 in retail sales and contributing more than
$9 × 109 in tax revenues (Southwick Associates 2012). Inland fisheries also support commercial fishing industries, such as in the Laurentian Great Lakes (Cooke and Murchie 2015)
and the African Great Lakes (Okeyo 2014), and
remain important in some European countries,
despite shifts in dietary preferences and multiple pressures on freshwater use and allocation.
Commercial fishing in France (Boisneau et al.
2016, this volume) was estimated to produce
1,186 metric tons valued at €10,470,000 (EU
2011).
Livelihoods reliant on inland fisheries,
whether recreational or commercial, are also
vulnerable to social, biological, environmental,
and economic changes that can reduce access
to inland fisheries or decrease the productivity
and value of the fishery (Cowx 2015). Because
inland fisheries provide different livelihood
benefits to different people (e.g., fisheries are
not always a livelihood of last resort), policies
regarding inland fisheries need to account for
the different livelihood values that fishers obtain from inland fisheries (Smith et al. 2005).
It is not sufficient to assume that fishers are
a homogenous group and that this allows the
blanket application of policies for management, development, or conservation.
114
youn et al.
Inland fisheries and their aquatic environment have essential cultural roles for many
rural (Fregene 2016; Ibengwe and Sobo 2016;
both this volume) and indigenous cultures
(Bartley et al. 2016) that largely rely on traditional freshwater resources (Clarke Historical
Library, no date). In the Northwest of the United States, more than 40 tribes have very close
cultural and livelihood ties to aquatic resources
(Ruby and Brown 1986). In fact, they refer to
themselves as the “people of the salmon,” and
they honor the salmon as their first indigenous
food gifted to them by the Creator (Columbia
River Inter-Tribal Fish Commission, no date).
The rights of the Pacific Northwest tribes to
fish for salmon are closely guarded by the
tribes. The ongoing struggle by the native people of North America to have their tribal fishing rights recognized has also occurred in the
tribal people of South America, specifically the
Amazonian region (Barra 2016, this volume).
It has been widely reported that the rights and
needs of the largely uncontacted tribes of the
Amazon River basin are being ignored during
development and transformation of the river
system by not only corporations, but also by
the governments that are supposed to protect them (Shukman 2012). The loss of access
to fishing and fishery resources threatens not
only food security, but also cultural traditions
and historical livelihoods sources; it may result in the long-term loss of cultural identity
and reduce the prospects of maintaining a traditional community and lifestyle into the future, particularly when compounded by other
environmental threats such as large-scale mining (Malm 1990), oil drilling, and governmentdriven deforestation (Shukman 2012). Malm
(1990) has shown that runoff from illegal, as
well as legal, mining and drilling operations
releases mercury-based compounds into the
Amazon watershed and river system, which
results in bioaccumulation within the freshwater fishery resources upon which these tribal
peoples depend (Malm 1990). In summary,
without representation on the local and global
stages, these groups are subjected to health
risks and shorter life spans due to reduced access to freshwater fishery resources (McClain
and Naiman 2008; UNPFII 2010).
Recommendations to Effectively
Communicate the Social and
Economic Value of Inland
Fisheries
Improving our ability to assess and communicate accurately and effectively the social and
economic value of inland fisheries is critical to
ensure both ecosystem and human well-being.
During the 2015 global conference on inland
fisheries, a group of panel experts explicitly
focused on this ongoing challenge. This panel
agreed that an approach, on local and international levels, that considers the social and cultural aspects of inland fisheries is needed so that
valuation of inland fisheries effectively includes
the social value of inland fisheries in addition
to their economic values. It is also important to
understand that fishers are not a homogenous
group and thus may vary in regards to the value
they place on various aspects of inland fisheries.
Indeed, while much research and management
effort has been expended on identifying drivers
of change affecting inland fisheries productivity and sustainability (Lynch et al. 2016a, this
volume), comparatively little attention has been
given to understanding the lives of the driven—
the people affected by change. In particular, the
perspectives and lives of those with unequal
social status (e.g., women, small-scale fishers)
need greater incorporation into inland fisheries and natural resource governance. They also
need to be included in decision-making processes, as inland fisheries are a key social and economic resource for these groups (McGoodwin
2001; FAO 2015). This panel formulated two
main recommendations that are now part of the
“Rome Declaration: Ten Steps to Responsible Inland Fisheries” (this volume): (1) correctly value inland aquatic ecosystems, and (2) promote
the nutritional value of inland fisheries. Below,
we expand on these two recommendations and
provide suggestions for moving forward.
Improve systems for ish
valuation—monetary and otherwise
Value methods that incorporate economic values with sociocultural values need to be used
in order to estimate the contributions of in-
unappreciated livelihood contributions of inland fisheries
land fisheries to human health and well-being.
Approaches used elsewhere in the natural resources sector and in the valuing and valuation
of ecosystem services may apply to the inland
fishery sector (Kontoleon and Swanson 2003;
Davidson 2013). Some examples of potential
economic methods that could be applied to inland fisheries include shadow pricing, replacement value, and willingness to pay (Smith 1996;
Howarth and Farber 2002), which have been
applied to other natural resources, such as applying shadow prices to adjust the market value
of stumpage (Huhtala et al. 2003). Assessments
from a public health, social, or ethnographic
perspectives may focus on themes such as understanding livelihoods, assessing health and
nutritional status, measuring well-being, the
analysis of class and gender dynamics, understanding relations of power and accountability,
the functions of governing institutions in fisheries and water-use decisions, and the value of local and indigenous knowledge systems regarding management of, and benefits from, inland
fisheries (UNEP 2010).
These methods have rarely been applied
to the inland fisheries context, in part because
of the limited attention these systems have
received to date. Using these methods in the
context of inland fisheries to increase knowledge and awareness regarding the ecosystem
services inland fisheries will provide and generate both monetary and nonmonetary values
(e.g., cultural, human health and nutrition, and
livelihood) for the appropriate assessment of
the contributions of inland fisheries to human
communities.
In addition to applying existing economic
assessment methods to inland fisheries, frameworks that are uniquely designed to incorporate traditional ecological knowledge, sociocultural values attributed to inland fisheries, and
the contributions of inland fisheries to human
ecosystem health and well-being are needed. In
order to do this, new approaches of measuring
social value must be developed. Some current
approaches (e.g., welfare valuation methods,
supply chain analysis) exist, but comprehensive
valuation frameworks that improve quantification of use and nonuse values (especially how
to appropriately quantify the importance and
115
value of culture and beliefs) of inland fisheries
need to be developed to ensure that important
hidden values are not dismissed or overlooked
in favor of simplified monetary cost–benefit calculations.
Valuation methods, such as comprehensive
impact assessments, should account for positive and negative spillover effects beyond the
fishery (wider impacts). Assessments should
incorporate both social and environmental
impacts (e.g., social and economic impact assessment) and propose mitigation strategies
where negative impacts are likely to occur. Additionally, frameworks that apply across contexts (e.g., geographical areas, waterbody type,
and fish species) would help to standardize
values assigned to inland fisheries and enable
comparison of the values of different fisheries.
Such frameworks would also enable freshwater
ecosystems to be weighted according to their
ecological and, by extension economic, benefits.
The most obvious application of this is ensuring that inland fisheries are more effectively
accounted for in broadscale planning of water
management or rural development.
Most importantly, the promotion and adoption of approaches that include valuation of inland fisheries along the entire fisheries value
chain (e.g., using participatory value chain analysis) should be supported to ensure that the real
value of a fishery is captured. Doing so would facilitate inclusion of social processes that affect
the value and perception of fish. This may also
help explain the price dynamics of inland fisheries products, which can often seem unrelated to
local contexts of supply and demand. The lack of
value chain considerations often results in the
somewhat limited assumption that the whole
value of a fishery lies at the first point of sale,
rather than acknowledging the value addition
and diffusion of economic benefits and nutrition
far from the source of fish. In some cases in Africa and Asia, these value chains extend across
countries and even into neighboring countries.
Communicate and promote the value of
inland isheries
Improving communication of information to
policymakers, freshwater users, and other
116
youn et al.
stakeholders is equally important in addressing research needs and data gaps concerning
the economic, health, and well-being benefits
of inland fisheries. Rendering information
on the value and functions of inland fisheries
in both human and environmental terms in a
form that is understandable to stakeholders is
critical to ensuring continued access and sustainable use of inland fisheries. Promoting understanding of the real value of inland fisheries
(incorporating economic, social, and ecological
values) is a crucial advocacy need. All too often,
the important contributions of inland fisheries
are overlooked or unknown, making it easy to
roll out policies and management decisions
that can directly compromise the sustainability
of inland fisheries and thereby impact human
health, well-being, and prosperity at the local,
regional, and international levels. To enhance
policy change, it is important to focus on the
points that resonate with policymakers, such
as the economic and social values of inland
fisheries and the contribution of inland fisheries to overall food security, human health, and
well-being. Additionally, awareness of the benefits of inland fisheries must spread beyond
those involved in inland fisheries, requiring
collaboration and communication with audiences outside inland fisheries, in particular
other sectors that utilize freshwater resources.

Abstract.—Inland fisheries are vital to the livelihoods of some rural peoples and
contribute a major source of protein, especially for vulnerable populations. Moreover, inland fisheries provide a major source of food and food security throughout
the Asian region but are often overlooked in national statistics and in considerations
of food security. Sixty-five percent of the reported global fish catch from inland fisheries is produced by 11 countries in the Asian region. Due to the poor quality of
reporting of inland fisheries, there is low confidence in the data, and this prevents
effective analysis at the subnational level. Inland fish, are, therefore, all but invisible
in official fish production figures.
The consumption of fish, however, can be estimated by national household surveys. These surveys are carried out on a regular basis and to a high level of statistical accuracy and can provide a wealth of information about consumption patterns
and habits. These data can also play a vital role in the development of fisheries and
natural resource policies that may have considerable impact on the most vulnerable
segments of the population.
This paper reports some results based on a regional review of fish and fish
product consumption derived from national household consumption and expenditure surveys. It also explores the implications for the use of this type of national
household consumption and expenditure surveys for improving our understanding
of inland fisheries and fish consumption. The paper concludes by discussing some
of the weaknesses in the use of surveys and how these may be improved to provide
far more effective information in support of understanding inland fisheries and its
role in food security

Asia (So-Jung et al. 2014). Based on the statistics
reported to the Food and Agriculture Organization of the United Nations (FAO 2014a), of the
16 countries of the world that produce 81% of
the world’s inland captured fish, 9 of these countries are in Asia (Figure 1). Eleven Asian countries produce 65.5% of global fish catch from
inland fisheries (Table 1), contributing 19% of
total reported fish catch for these 11 countries.

These inland fisheries are present throughout
the large river floodplains, deltas, and rice farming areas of Asia. The large man-made irrigation
tanks and reservoirs of the region also provide
considerable quantities of fish in some countries. Inland fish consumption is not confined
to lowland floodplains, as even in mountainous
areas fish are still a prized food in many cultures
in Asia (Needham and Funge-Smith 2015).

The reported inland capture fishery harvests for these 11 Asian countries are relatively significant, although these are often substantially lower than marine capture fishery
production. Comparisons between inland and
marine capture fisheries and aquaculture may
hide the real importance of inland fisheries at
the subnational level because inland fishery
harvesting is often focused around specific
areas where water resources are most abundant. Areas where freshwater resources are
relatively abundant year round or seasonally
are highly linked to increased rates of fish consumption. This local importance of inland fishing in contributing to access to fish for household consumption may be discerned to some
extent by looking at the subnational details of
fish consumption, derived from a household
expenditure and consumption survey. For example, the fish consumption survey data of
Laos indicates that the highest levels of per
capita fish consumption in Laos occur in provinces along the path of the Mekong River; these
areas have substantial fisheries harvest, have
access to imported fish from Thailand, and also
have cage and pond aquaculture production
(Department of Statistics 2010). The lowest
levels of fish consumption are in upland areas
where fish production from rivers and streams
understanding the role of inland fisheries in food security and nutrition
is lower and there is relatively less aquaculture
production (Figure 2.). Inland fishery capture
production is, therefore, often considerably
underestimated (Coates 2002) and the true
importance of inland fisheries maybe diminished or undervalued in aggregated statistics
at the regional or national level.
Asian Inland Fisheries Are Not
Well Monitored and This Limits
Appropriate Valuation
Despite their importance within some countries, the harvest from inland fisheries remains
poorly reported or even overlooked in national
123
statistics and in considerations of food security (FAO 2014b). The ability to understand and
value inland fisheries remains critically linked
to statistical and resource accounting systems.
However, in many countries these systems are
not appropriate for tracking inland fisheries.
The systems for data collection and statistical
analysis are typically weak in many developing countries, and this is compounded by the
constraints on collecting accurate statistical
data from inland fishery landings (Welcomme
et al. 2010). There is generally limited investment in data collection and analysis for inland
fisheries. This limited investment is partially
because the cost of data collection is not eas-

ily justified by the revenue generated and fishing activity is rarely organized to a point that
allows simplified data collection. Sampling
schemes are rarely used for estimating inland
fisheries harvest, the exception being large water bodies such as reservoirs and commercial
fishing concessions. These large water bodies
may be subject to greater monitoring and taxation, but this in turn drives underreporting by
fishers. The inadequacy of reported statistics,
coupled with the lack of subnational disaggregation for these data, severely limits meaningful discourse about what inland fisheries contribute to national and local economies, diet,
livelihoods, and ecosystem services (Bartley et
al. 2015).
Consumption Surveys May
Improve Estimates of Inland
Fishery Harvests that Are Made
without a Firm Statistical Basis
In some countries, the complete absence of a
statistical system means that the estimate of
inland fishery harvest is essentially guesswork.
There may be some indicative fisheries monitored, but inherent reporting weaknesses and
the lack of representation of some key inland
fisheries (e.g., rice field fisheries) means that
these data cannot be used to derive an accurate national estimate. Contributing further to
the inaccuracy of these data is the potential to
have incremental increase applied year by year
to the harvest estimates to satisfy government
targets for increased harvest (author’s personal
observation). This can lead to very substantial
accumulated errors during the course of a decade or more. For example, the inland capture
fishery statistics of Myanmar indicate a massive
increase (389%) during a decade (FAO 2014a).
This was perhaps driven by the realization
that historic reports had been greatly underestimating harvests from inland fisheries (Figure 3); however, the annual increase seems to
have become institutionalized. The continuous
increases year by year are too systematic and
show neither natural variation nor interannual
variation, as would be demonstrated in fisheries
that were actually monitored. This lack of varia-
tion is considered to be a strong indication of
inland fisheries harvests being estimated without validation by Coates (2002)
The use of household consumption survey
data provides one approach for validating the
reported inland fisheries productions. Having
some form of validation would be helpful, especially in cases where very large changes in
inland capture fishery statistics have been reported and where the inland fishery harvest
statistics are not based on catch collection
data, but on estimates. For example, the household consumption survey (2011) for Myanmar
indicates that 75% of fish consumed were from
inland or estuarine waters and that the majority of this was sourced from capture fisheries
(Needham and Funge-Smith 2015). This gives
an approximate figure of 750,000 metric tons
for inland capture fisheries and indicates that
the 2013 inland capture fishery statistic of
1,302,970 metric tons (FAO 2014a) may be
now be overestimated by as much as 42%.
This highlights the potential for using statistically robust consumption surveys as a means
to validate inland capture fishery harvest.
Before being too critical of weak inland
fisheries statistics, it is important to recognize
that that household consumption surveys may
underestimate consumption. Thus, the reported figure for inland capture fisheries may
not be as overestimated as it first appears, but
there is clearly substantial discrepancy that
merits further investigation.
Estimations Based on Indicators
such as Consumption Surveys
Can Radically Change Estimates
of Production
Implementing a new study or relying on alternative data to produce a robust new estimate
within a country may result in a massive leap in
the reported estimated production. An example
of how including new data can drastically alter
the reported statistic is Cambodia’s inland capture fisheries production estimates. Cambodia’s estimate (Figure 4) leapt 205% in 1999,
followed by a second substantial increase of
57% in 2001 (FAO 2014a). The large increase

was unofficially explained as being caused by
inclusion of unmonitored small-scale fisheries
to the estimate. Previous reported estimates
only covered those concessional fisheries that
were monitored. This increase in Cambodia’s
fisheries production reported estimate was
further substantiated as not being excessive by
the findings of two reports published in 2007
and 2013 that relied on consumption survey
data. The 2007 report is a fisheries informa-
tion research project that commenced after
the 1999 and 2001 reported estimates. This
project, undertaken by the Mekong River Commission and the Cambodian Fisheries Administration, indicated that the Cambodia inland
fishery harvested approximately 587,000 metric tons per year (Hortle 2007). This methodology included comparisons with information on
household consumption as a means to estimate
likely production, in the absence of compre-

hensive inland fishery statistical monitoring.
The 2013 report summarized the findings of
a Cambodian consumption survey conducted
during 2011–2012. This report indicated that
inland fish constituted 71% of the total annual
fish consumption (63 kg per capita per year),
which gives an estimate of inland fishery production of 632,000 metric tons (IFReDI 2013).
This production figure estimated from the
reported consumption is higher than the currently inland capture fishery production figure
reported to the Food and Agriculture Organization of the United Nations (FAO). This suggests
that even the current estimates of Cambodian
inland fishery production reported to FAO may
still be underestimated.
understanding the role of inland fisheries in food security and nutrition
Consumption Surveys May
Explain Large Variations in Inland
Fishery Production Estimates
Countries that have a statistical system for
monitoring inland fisheries will derive an estimate of harvest that, depending on how it is
derived, may drift off over time from the actual
level of production. This drifting from the actual production level is an artifact of the approach used to derive the estimate. Countries,
therefore, periodically reset the harvest estimate based on a validation methodology. Some
validation methods that have been used include household consumption surveys, 5–10year agricultural/population census, periodic
fishery survey, and fishery sampling programs.
Incidences of periodically reset harvest estimates can be seen when there are occasional
instances of very large annual variations in
the estimate reported by a country. These annual variations are so large that these cannot
be easily explained as natural variability in
127
production level resulting from climatic variations. Occurrences of reset have been noted
in the reported inland fisheries catches for
several countries in Asia by Lymer and FungeSmith (2009). An example of where this may
be occurring is in India’s reported inland fishery production (Figure 5). During the period
1950 to 2012, there are 13 instances of an interannual variation of more than 20% and four
instances where the interannual variation is
greater than 40%. This is indicative of where
the reported inland fishery production rises or
decreases by such a substantial amount that
cannot readily be explained by natural environmental or biological variability or the level
of fishing activity. This is illustrated by the lack
of coincidence of the large variation years with
reported drought years, where a substantial
decrease in the production might be expected
in the subsequent year. Thus, India, may be applying a validation method, such as data from
household consumption survey or other method, to reset its production estimate.

Consumption Surveys May
Prevent Inland Fishery Production
from Being Misreported as
Aquaculture Production
The contribution of inland fisheries to diets and local economies may be undervalued
when inland fishery harvests are incorrectly
attributed to aquaculture production. This incorrect attribution may lead to fish production
from aquaculture being overestimated, the
result being that aquaculture is given unjustified prominence as the principal source of fish
production in the country. The policy ramifications of this are that investment and development effort may be misdirected into promotion
of aquaculture rather than sustainable management of inland fisheries.
In Laos, there is relatively good agreement
between the food balance sheets (18.2 kg per
capita per year, 2007) and the consumption
estimate from the fourth Laos expenditure and
consumption (Department of Statistics 2010)
household survey (19.1 kg per capita per year).
This agreement breaks down when the source
of fish is considered. The Lao expenditure and
consumption survey indicates that the inland
capture fishery provides approximately 88% of
the fish consumed. The inland fishery and aquaculture statistics reported to FAO, which form
the basis of the food balance sheet estimate, indicate that inland capture fisheries only provide
25% of total national production, with the bulk
of production attributed to aquaculture.
Laos does not have a comprehensive inland fishery monitoring system, and even
aquaculture production is an area-based estimate. In this example, it appears that inland
fishery harvest is being grossly underestimated and that aquaculture production estimates
are possibly inflated. The use of household
surveys offers a means to validate the sources
of production and even check the likely level of
production reported. In the case of Lao PDR,
where there are relatively limited imports and
exports, the methodology can be considered to
be reasonably reliable compared with estimations based on production areas and their assumed productivity.
Consumption Surveys Have
Limitations
In the examples provided above, consumption
survey data have been used to provide an alternative estimate of fish consumption to validate
reported inland fishery harvest. In many cases,
household surveys may provide information
that is not sufficiently detailed to be used to reliably estimate inland fishery harvest. Common
reasons for this are as follows:
•
•
•
•
Survey questions may not distinguish between the sources of fish. The surveys
can typically distinguish between freshwater and marine fish (on the basis of the
species). In many cases household surveys
cannot distinguish whether the fish consumed was produced from capture fishery
or aquaculture;
It is difficult to distinguish between consumption of locally caught fish and imports, particularly near borders;
Respondents are often unaware of the
source of the fish they purchase;
Anadromous species (e.g., Hilsa Tenualosa ilisha, Asian Seabass [also known as
Barramundi Perch] Lates calcarifer) and
catadromous species (e.g., mullet, prawns
Macrobrachium spp.) may be caught in
freshwater, brackish-water, and marine
environments, and the location of the fish
at time of capture may not be distinguished. This is a particular challenge in
assessing fisheries in the large tropical
river delta areas (e.g., Ayerwaddy, Mekong,
and Bramaputra), as well as inland brackish and freshwater lagoons (e.g., Songhkla
Lake, Hue Lagoon).
Household consumption surveys are
known to have weaknesses associated with
their data collection process, such as follows:
•
•
•
Surveys rely on recall of consumption and
this may lead to underestimation and
overestimation errors;
The survey respondent may be quite unaware of the consumption of other household members, and often underreport; and
Well-structured consumption surveys
record consumption of different forms of
understanding the role of inland fisheries in food security and nutrition
fish (e.g., fresh, frozen, fillets, canned,
dried, smoked, and sauce) and, unless corrections are made, will underestimate fish
production. To circumvent this, all weights
must be converted to fresh weight equivalents, allowing for losses due to parts not
eaten.
Consumption Surveys Can Reveal
Much about Inland Fisheries in
Cases Where National Monitoring
Systems Are Not in Place or Where
Subnational Detail Is Lacking
Although consumptions surveys cannot deliver
fishery trend data on annual basis, they may indicate long-term trends in the source of production and even the species consumed. They can
indicate the differences in consumption habits
of rural and urban populations (Needham and
Funge-Smith 2015).
Consumption surveys offer an insight
into variations in subnational fish consumption and, as a proxy, fish production. The
main value of the consumption survey is to
act as a means of validating estimates of inland fishery production in situations where
an effective fishery monitoring system is not
in place. These may also allow a means to estimate the hidden production of small-scale,
diffuse household fishing, which may not be
captured in existing statistical monitoring
systems, and act as a means of resetting gross
overestimates or underestimates of fish production.
Conclusion
In situations where consumption surveys are
considered to be the best approach to estimate
or validate inland fisheries harvest, improvements could be made by
• Undertaking a 4-monthly or quarterly validation survey to correct for seasonality
variations;
• Structuring the survey to collect data
throughout an annual cycle to reduce recall errors by respondents;
• Improving questions to resolve the disag-
•
129
gregation between aquaculture and capture harvest; and
Including a 5-yearly consumption survey
alongside or in between other national
fishery surveys.
Without improving information about inland
freshwater harvests, the real value and importance of inland fisheries remains hidden and,
more importantly, greatly undervalued.

The Value of Tanzania Fisheries and Aquaculture:
Assessment of the Contribution of the Sector to
Gross Domestic Product

Abstract.—The socioeconomic importance of the Tanzanian inland water
and small-scale marine fishing industry and aquaculture sector in the country’s
development cannot be understated. With a coastline of 1,450 km2 and richly endowed with natural water bodies, the fishing industry plays a fundamental role
in food security, sustainable livelihoods, and poverty reduction. However, the
fishing industry and aquaculture sector’s contribution has been underestimated
in past years; hence, it is not fully recognized as an economic sector that contributes significantly to the country’s gross domestic product (GDP). The published
value of the fishing industry and aquaculture sector contribution to the GDP is
not reported holistically. The GDP contribution of the fish harvesting sector of
the fishing industry is estimated by the National Bureau of Statistics as part of
the agricultural gross product (AGP), in accordance with the System of National Accounts (SNA). The AGP accounts for only the value of the fish harvesting
sector’s activities, whereas the economic contributions of postharvest-related
activities are accounted for under other sectors like manufacturing. This study
focused on providing appropriate information about the overall value of the fishing industry and aquaculture sector. A production approach method was used to
evaluate value-added contributions to the national GDP. The analysis found that
the fishing industry and aquaculture sector’s contribution to the GDP in 2011
was 3.07% as compared to the published GDP of 1.4%. This difference suggests
that the fishing industry and aquaculture sector’s contributions to GDP may
have been underestimated by a factor of 2.2 and indicates that a postharvesting
processing sector plays a significant role in GDP contribution. These findings
provide a different perspective on how to calculate fishing industry and aquaculture sector contribution to the GDP from the existing structure of economic
activity classification set by the SNA. To complement this information, the study
also summarizes the contribution of the fish harvesting, postharvest processing
and aquaculture sectors to employment. This study also calls for improved data
collection and information related to the fisheries’ postharvest activities. At the
policy level, there is a need to rethink and prioritize development of the fishing
industry and aquaculture sector in Tanzania.

Background and overview of the Tanzania
ishing industry
Overview of the aquaculture sector in
Tanzania
Tanzania lies just south of the equator and covers an area of about 947,300 km2 (CIA 2012).
The country is rich in water resources; about
62,000 km2 is covered by various water bodies that include the three largest lakes in Africa,
diverse river systems, numerous wetlands, and
a coastline of 1,424 km long along the western
Indian Ocean (EAF-Nansen Project 2012).
The fishing industry1 is economically and
socially significant to the country, and it plays
a fundamental role in food security, sustainable livelihoods, and poverty reduction. The
inland and small-scale marine fish harvesting
sectors officially contribute around 1.4–1.6%
of the national gross domestic product (GDP;
Planning Commission 2012; Figure 1). The
fishing industry also contributes about 10%
of the country’s total exports from fish and
fishery products (Ministry of Livestock and
Fisheries Development 2012) and provides
Aquaculture in Tanzania is a fast-growing sector that provides national food security and
supports livelihoods for people living along the
coast and inland areas. There are about 17,847
fish farmers in Tanzania, of which 14,750 fish
farmers are involved in freshwater fish farming and 3,097 in mariculture (Ministry of Livestock and Fisheries Development 2012). Annual farmed fish production is estimated at
3,628.5 metric tons, which is about 0.98% of
the average annual fish landings.
The decline of capture fisheries harvest
from inland and territorial waters, coupled
with the ever increasing demand for fish, has
created an urgent need to promote aquaculture development in the country (F. A. Sobo,
paper presented at the Workshop on Fisheries
and Aquaculture in Southern Africa: Development and Management, 2006). The government has developed the National Aquaculture
Development Strategy, which sets the framework for promoting commercial aquaculture

Contribution of the ishing industry and
aquaculture sector to the gross domestic
product
Though not fully recognized as major contributors to the GDP, the fishing industry and
the aquaculture sector are important contributors to many national economies across
African countries. In terms of food security,
revenue generation, and employment derived
from activities related to these sectors, both
the capture fisheries and aquaculture sectors
continue to be of fundamental importance, as
can be seen by the tonnage and value produced
(World Bank 2012).
In Tanzania, the contribution of the fishing
industry and aquaculture sector to GDP is published by the National Bureau of Statistics. The
calculation is based on the System of National
Accounts; however, it incorporates only the
GDP of the fish harvesting sector while related
postharvest activities are considered under
the manufacturing section (UN 2008).
The fish harvesting and aquaculture sectors are clearly an important direct source of
employment (FAO 2007). A study by the World
Bank indicated that the contribution to the
GDP created by postharvest activities in some
African countries can be high, making up more
than 50% of the fishing industry’s contribution
to the GDP (World Bank 2012). Therefore, it is
in the interest of the Tanzanian fishing industry to understand the fish harvesting, postharvest processing, and aquaculture sectors’ contribution to the national GDP.
The GDP is the sum of economics of each
sector to the performance of the whole economy within a country in a year, or a given
period of time (Timmer 1992). A sector can
contribute directly and indirectly to the economy (Cai et al. 2009). According to National
Accounts: A Practical Introduction (UN 2003),
there are three approaches to calculate GDP
(UN 2003):
•
•
•
Production approach,
Expenditure approach, and
Cost or income approach.
133
The most direct and common way to estimate
GDP of the three approaches is the production
approach through estimation of gross added
value (UN 2003).
The present study applied the production
approach to estimate the economic contributions of fish harvesting (production), postharvest activities, and employment generated by
the sectors. The production approach estimates
the GDP by assessing the gross value added of
each economic activity in the national economy.
Gross value added is an economic measure of
the value of goods and services produced in
an area, industry, or sector of an economy (UN
2003). It measures the increase in income after
the costs of intermediate inputs into the production have been deducted.
Signiicance of the study
There is a knowledge gap in the Tanzania Fisheries Development Division regarding the contribution to GDP from the whole value chain of
the fishing industry and aquaculture sector to
the national GDP.
So far, there has never been a study conducted to estimate the whole value chain of the
Tanzanian fishing industry and aquaculture
sector contribution to the national GDP.
This study attempts to fill in critical
knowledge gaps in understanding the fishing
industry’s and aquaculture sector’s economic
importance to the country. The results of this
study should challenge existing perspectives
of the marginality of the fishing industry and
aquaculture sector in developing countries
and should give attention to policy makers to
prioritize development support to the fishing
industry and aquaculture sectors.
The main objective of this study is to provide appropriate information about the overall
value of the fishing industry and aquaculture
sector.
The specific objectives of the study are
•
•
to provide accurate information about the
contribution of the fishing industry and
aquaculture sectors to the GDP,
to provide specific information about the
employment generated by the fishing industry and aquaculture sector, and
ibengwe and sobo
134
•
to improve fisheries data collection related
to the required components for calculation
of the GDP.
Methods
Data collection
The study was conducted between January and
March 2012. Information was collected from
the fish harvesting, postharvest processing, and
aquaculture sectors and licensing. Information
related to employment for each of these sectors
was also collected and analyzed. The primary
data collection involved direct field observation, focus groups, and structured interviews
with fishers, fish farmers, and processors. The
interview was distributed across Lake Victoria,
Lake Tanganyika, Lake Nyasa, minor freshwater bodies, and marine territorial waters. Field
work mainly occurred at the Kirumba fish market, Kayenze and Igombe landing sites for Lake
Victoria; Kibirizi and Korongwe landing sites for
Lake Tanganyika; and Ferry fish market, Masoko-pwani and Mikindani landing sites for the
marine water, while information for processing
was obtained from Vic Fish Ltd and Nile Perch
Fisheries Ltd fish-processing plants. The interviews were conducted by fisheries officers from
the Tanzania Fisheries Development Division
and the Local Government Authority.
For the fish harvesting and aquaculture sectors’ questionnaire, a total of 120 fishers and fish
farmers were interviewed, and these formed
a representative sample for the study; 44% of
the fishers interviewed were from Lake Victoria, 30% from Lake Tanganyika, and 26% from
marine territorial waters. Information about
the employment provided by the fish harvesting
and aquaculture sectors was also collected.
For postharvest processing and employment in the postharvest sector sections, 230
processors were interviewed about this sector’s
economic contribution and related employment. To obtain a representative sample for
the study, respondents were randomly sampled
(gender-representative). About 69 of the processor respondents interviewed were from
Lake Victoria, 64 from Lake Tanganyika, 58 from
marine water, and 39 from industrial processing
plants. The information obtained for each sampled landing site, market, and processing plant
was extrapolated based on the total number of
smoking kilns, drying racks, frying facilities, and
processing plants for industrial processing provided from frame survey reports.
The licensing section of the questionnaire
gathered information from the Fisheries Annual
Statistics Report 2011 (Ministry of Livestock
and Fisheries Development 2012), specifically
about the total number of licensed fees, which
consisted of a fishing license fee, fishing vessel’s
license fee, and the vessel registration fee.
Primary data collection about the fish harvesting, aquaculture, and postharvest processing sectors and licensing and information about
employment was complemented by secondary
data sourced from the Fisheries Annual Statistics Report 2011 (Ministry of Livestock and
Fisheries Development 2012), and frame survey
reports for Lake Victoria (Ministry of Livestock
and Fisheries Development 2010); Lake Tanganyika (Ministry of Livestock and Fisheries Development 2010); and marine waters (Ministry
of Livestock and Fisheries Development 2009).
The data collected from the fish harvesting,
postharvest processing, and aquaculture sectors and licensing were compiled and analyzed
in Microsoft Excel.
Questionnaire
A standard questionnaire developed by the
Food and Agriculture Organization of the
United Nations (FAO) and the New Partnership for Africa’s Development NEPAD-FAO
Fish Programme (de Graaf and Garibaldi
2014) was used to collect data on the economic contribution and employment of the
fishing industry and aquaculture sector. The
questionnaire was divided to address all of
the fishing industry and aquaculture sectors,
and information was gathered from the relevant subsectors (Table 1).
The information gathered for the fish harvesting and postharvest processing sectors
and licensing was further organized by fishing
unit. Four classifications were used for the marine small-scale fisheries and the inland smallscale fisheries subsectors (Table 2).

Analysis and Results
Analysis of the gross value added of the ish
harvesting sector
Analysis of gross production value for the
fish harvesting sector.—The fish harvesting sector’s GPV for the inland small-scale fisheries and
the marine small-scale fisheries was calculated
for each of their four fishing units (Table 2) using equation (3). The analysis indicated that
the GPV for the fish-harvesting’s inland smallscale fisheries, all fishing units combined, was
1,328,538,967,109 Tanzanian shillings (TSh)2
and was TSh 231,748,777,100 for the marine
small-scale fisheries.
Analysis of production cost by fishing units
for the fish harvesting sector.—The production
cost was calculated as shown in equation (5)
and included the following information for
each fishing unit (Table 3):

replacement cost of fishing gears;
Cost for buying kerosene for lamps or lanterns and replacement cost for maintaining sail cloth; and
Cost for boat repair; service charges for
running generators and lamps; and cost
for buying generators (KV6/KV4), fuel,
and food.
Analysis of value-added ratios and gross
value added of the fish harvesting sector by fishing units for both the marine small-scale fisheries
and the inland small-scale fisheries.—The results
of the analysis of the VAR (equation [4]) and
GVA (equation [2]) for each fishing unit are presented in Table 4. The annual fishing landings
for all fishing units combined is greater in the
inland small-scale fisheries, with 290,474 metric tons and a GAV of TSh 820,850,440,209 than
that of the marine artisanal/small-scale fishing
subsector (Table 4).
Analysis of gross value added of the
postharvest processing sector
Gross value added (equation [2]) was also applied to analyze GVA for the postharvest processing sector. The calculation considered the
whole processing value chain of fish after being landed and the conversion factors of the
processed products to standardize the weight
of fresh fish used in the GVA calculation (Table
5). The following variables were collected:

Analysis of gross value added from licensing
The questionnaire collected information of licensed fees per vessel for inland small-scale
fishing, marine small-scale fishing, marine industrial locally based fishing, and marine industrial foreign-based fishing. License fees in
this section refer to those paid by local fishers
to the central government and local government authorities, the following are three types
of licenses fees paid by local fishers:
•
•
•
Fishing license fee equivalent to US$10/
year,
Fishing vessels license equivalent to
US$10/year, and
Vessel registration fee equivalent to
US$10/year.
Items covered in the licensing section of
the questionnaire were number of fishing units
by type of fishery, license fees (local currency)

Data about production cost (equation [5])
and VARs (equation [4]) were not calculated
for the licensing section, and therefore, the
GVA (equation [2]) was regarded to be same as
the GPV (equation [3]). The analysis provided
a GVA of about TSh 2,797,626,000 from the licensing activities (Table 7).
The overall analysis of this study reveals
that inland small-scale fisheries contributed
2.51% (Table 10) and aquaculture contributed 0.05% to the country’s total GDP (Figure
2).
The result shows that total GVA for the
fishing industry and aquaculture sectors are
TSh 1,150,335,556,392, which represents a
contribution of 3.07% to the country’s GDP of
TSh 37,532,962,900,000 (Table 11).

The GVA for aquaculture was calculated using

TSh 19,876,186,000 (Table 8).
The fishing industry and aquaculture sector
support livelihoods for many people in Tanzania by providing employment to fishers who
engage on a full-time basis and through various fisheries-related activities, such as boat
building, net making, local and industrial fish
processing, fish trading, and fish farming (FAO
2007).
Employment through the fish-harvesting
(marine small-scale fishing, inland small-scale
fishing, and postharvest processing) and aquaculture sectors.—This study estimated the details of the employment generated by the fish
harvesting, postharvest processing, and aquaculture sectors from inland freshwater bodies
and marine water. The Fisheries Annual Statistics Report 2011 (Ministry of Livestock and

ployment in these three sectors was 185,683
jobs (Table 12).
The results shows that a higher percentage
of male fishers compared to female fishers participate in fishing activities from both the inland
small-scale fishing subsector (98.3% and 1.7%,
accordingly) and the marine small-scale fishing
subsector (89.6% and 10.4%, accordingly).
Employment through postharvest processing.—The analysis indicated that 257,339 people
are employed in industrial processing from inland and marine small-scale fisheries (Table 13).
The analysis of employment in fisheries
processing activities shows that high percentages of females are engaged in processing activities. About 53.1% are involved in processing
activities from inland water, while in marine water, female participation was 51.8%.

implications for the social and economic welfare of fishers, processors, fish farmers, and
the nation at large. However, the national policies overlook the sectors due to their assumed
relatively minor economic contribution to the
national GDP.
This study examines the value of the fishing industry and aquaculture sector. The study
is expected to change the general perception
of the fishing industry and aquaculture sector
in Tanzania, and it is very likely that similar
lessons can be drawn in other African countries with regards to the importance of these
sectors.
The present study found that the fishing
industry and aquaculture sector have a GDP
contribution of up to 3.07%, which is an aggregate of the fish harvesting sector (2.63%),
postharvest processing sector (0.38%), licensing (0.01%), and the aquaculture sector
(0.05%). Clearly, the study shows that, the fish
harvesting sector was the key contributor to
the GDP. The analysis also indicated that inland small-scale fisheries contributed about
2.51%, followed by marine small-scale fisheries at 0.51% and aquaculture at about 0.05%.
The inland small-scale fisheries have a high
contribution because of their high production

ment, when compared to marine fisheries and
aquaculture.
The fishing industry and aquaculture sectors have always been important for supporting employment in the country. The study
shows that the postharvest processing sector
supports more than half of the employment
in the fishing industry and aquaculture sector,
with an overall approximation of 257,339 fish
processors. This is more than 64 times the estimate of the 2007 country fisheries profile (FAO
2007) of about 4,000 processors. This study
reports a much higher estimate of processors
because fisher communities are increasingly
engaging in fish-processing activities. Furthermore, the results noted that fish-processing
activities were almost equally distributed between males and female (48.8% and 51.2%,
respectively). Though the small-scale local
processing sector is relatively small, it has
great potential for generating employment
opportunities and contributing to poverty alleviation, particularly for women. A study in
Gambia by the United Nations Conference on
Trade and Development indicated that fishprocessing activities, a light type of work, are
female-intensive (UNCTAD 2014), whereas the
total fish harvesting sector (inland small-scale
fishing and marine small-scale fishing) was

male-dominated, with 98.3% and 89.6% of the
total employment being male for inland smallscale fishing and marine small-scale fishing,
respectively.
This study indicated that the present estimates for contributions of the fishing industry
and aquaculture sector to the GDP are conservative; the actual values are likely to be higher
as found in this study. The study did not include GVA from the exclusive economic zone
(EEZ) because it was not possible to establish
the production costs and average vessel price/
kg from industrial tuna purse seiners and longliners that would be used in calculating the
GVA. Doing so would have increased economic
benefits from the fishing industry. Still, this
study has provided new and comprehensive
information of the value of Tanzanian fishing
industry and aquaculture sector, which is of
importance for managing fisheries resources
in Tanzania.
On a national scale, the results suggest an
urgent need to improve fishing industry and
aquaculture sector data collection, specifically
including the value of GDP contribution of the
postharvest processing sector to the GDP value
of the fishing industry and aquaculture sector.
The contribution of the value of the fishing industry to the GDP emphasizes the importance
of investing in development projects for this
industry, such as the construction of a fishing
harbor that will handle fish from commercial
fishing vessels operating in the EEZ. The availability of a fishing harbor will contribute to the
optimal use of existing EEZ resources through
employment, income generation, food security,
revenue, and foreign earnings.
At the policy level, this finding should catalyze national and policy maker to reexamine
the existing policies that neglect the fishing industry and aquaculture sectors and contribute
to prioritizing support for fisheries development in Tanzania.
Challenges and
Recommendations
The results indicate the importance of the fishing industry and aquaculture sector in Tanzania in the provision of employment and con-
tribution to the country’s economy. However,
some of the challenges encountered during the
course of the study include lack of data available to calculate GVA marine industrial fishing
(tuna long-liners and purse seiners) from the
EEZ.
Therefore, it is recommended that
•
•
•
•
Detailed studies be carried out to include
GVA of the industrial tuna long-liners and
purse seiners from the EEZ, as well as to
determine employment from other post
harvest activities (boat building, net mending, etc.);
Construction of fishing harbor be carried
out that will optimize utilization of the existing EEZ resources, thus benefiting the
country;
The Ministry of Livestock and Fisheries
Development and the National Bureau of
Statistics review the calculation of the sector to GDP; and
Data about the economics of fishing units
and employment in the local and industrial processing sector be incorporated in
data collection forms.

Abstract.—Major rivers and flood ponds in Taraba State, Nigeria are important
to the livelihood of fishers and their households. But overfishing and destructive
fishing practices have occurred in some of the water bodies. This study examined
the characteristics of fishing operations, benefits derived from these operations,
nonfishing-based sources of livelihood, and the benefits of fishers and community
involvement in the management of these water bodies. A multistage sampling method was used to select fishing households for this study. The first stage involved selecting local government areas from the four Taraba State Agricultural Development
Programme (ADP) zones. Then, fishing households were proportionally selected
from the eight local government areas selected in the first stage. A total sample of
200 fishers was used for the study. Qualitative data were obtained from fisheries
government agency extension personnel and leaders of the fishing communities
through in-depth interviews. Quantitative data were collected through structured
questionnaires. The data were analyzed using descriptive statistics, profit margin
analysis, t-test, and analysis of variance. Types of fishing gear used, fish species
caught, and benefits derived from fishing, as well as other sources of livelihood,
were documented. Taboos and beliefs used by the fishers aimed at preserving the
fish species and environment of the water bodies were included in the paper. Result
of the profitability analysis showed significant differences in fishers’ incomes based
on whether or not the fishers owned an outboard engine, and between ADP zones.
The paper recommends that a management process involving multi-stakeholders
should be implemented to better attain sustainable livelihoods for fishers and food
security.
Introduction
The fishery sector in Nigeria is a major source
of income for those inhabiting communities
near water bodies. According to Ovie and Raji
(2006) fisheries contribute to the nation’s
economy in terms of food security, employment, poverty alleviation, foreign exchange
earnings, and provision of raw materials (protein source) for animal feed industries. Fish
harvested constitute about 41% of the total
animal protein intake by the average Nigerian; hence, there is great demand for fish in

the country (FMARD 2011). The Federal Ministry of Agriculture and Rural Development
(FMARD 2012) reported that artisanal fisheries have continued to dominate Nigeria’s
domestic total fish supply of 968,283 metric
tons by contributing more than 69% (668,754
metric tons). In terms of direct-use values, inland fisheries contributed 45% (297,836 metric tons) of the total artisanal fish harvest in
2012. Artisanal fishers use a small amount of
capital and energy, as they make short fishing
trips in small (if any) canoes close to shore,
and the fish harvested are mainly for local
consumption (FAO 2015). Even though their
fishing operations are small-scale in nature,
147

their activities yield nutritional benefits and
fish food supply for domestic consumption by
the poor (Fregene 2002).
Taraba State is drained by four major rivers, Benue, Donga, Taraba, and Ibi, and their
tributaries. They arise from the Cameroon
Mountains, draining almost the entire length of
the state in a north and south direction to link
up with the Niger River (Oruonye and Bashir
2011). The state has about 500,000 ha of water bodies and 142 natural ponds (TSEEDs
2004, cited by Oruonye 2014). These rivers
and ponds in Taraba State are major sources of
livelihood for the fishers and their households.
However, few studies have been conducted at
the household level, and there are few management strategies targeting the conservation
of the fisheries resources, especially in fishing
communities in Taraba State.
This study examined characteristics of
fishers, fishing operations, and fish species
caught; other sources of livelihood and benefit derived; profitability of fishers; and community involvement in the management of the
water bodies. Two null hypotheses in the study
were tested as follows:
1.
2.
Annual profit among fishers with outboard
engines and those without outboard engines are not significantly different, and
Significant differences do not exist between the artisanal fishers operating in
the four Taraba State Agriculture Development Programme (ADP) zones.
Study Area
Taraba State is located northeast of Nigeria and
has a total land area of 54,428 km2 extending
between latitudes 6°25’N and 9°30’N and longitudes 9°30’E and 11°45’E. It is bounded in
the north by Gombe State, in the west by Bauchi and Benue states, in the east by Adamawa
State, and on the south by Cameroon (Oruonye
and Bashir 2011).
The state is located within the guinea
savanna zone (Taraba State Agricultural Development Programme 2009). It has a tropical climate characterized by well-marked
wet and dry seasons. The wet season usually
starts from April and ends in November with
an annual rainfall varying from 1,250 mm in
the north to 2,500 mm in the southern part
of the state, with an annual average temperature of 26.7°C to 27.8°C, with lower temperatures occurring towards the south (TSADP
2009). The dry season begins in November
and ends in March. The estimated population
is 2,280,483 (NPC 2006). It is a multiethnic
state inhabited by a number of ethnic groups:
Tiv, Kuteb, Chamba, Jukun, Hausa, and Fulani,
who are predominantly farmers and engaged
in different types of activities such as fishing,
hunting, local craft, and tailoring.
Methods
A survey was conducted in which a multistage sampling technique was used (Villareal
et al. 2004). In the first stage, 8 of the 16 local
government authorities (LGAs) were selected
from the four ADP zones: North, South, Central,
and Gambo. These eight LGAs have high concentrations of fishing activities (Figure 1). In
the second stage, fishing households were proportionally selected from the eight LGAs using
the list of registered fishers collected from the
Divisional Fisheries Office, Taraba State Ministry of Agriculture and Natural Resources
(MANR), Jalingo. A sample size of 200 fishing
households, which is 0.46% of the total number of fishermen in the eight LGAs (43,933),
was used for the study (Table 1).
Qualitative data were gathered using
semistructured questionnaires during oral
interviews with extension personnel of fisheries government agency, and from leaders of
the fishing communities through in-depth interviews (J. E. Olawoye, University of Ibadan,
unpublished data). Quantitative data were collected from structured questionnaires administered to fishers by extension agents through
individual surveys (Callerholm Cassel and Jallow 1991; Villareal et al. 2004)
Statistical analysis and hypothesis testing
Data were analyzed using descriptive and
inferential statistics. Descriptive statistics
included frequency, percentages, and profit
margin analysis. T-test and analysis of variance were the inferential statistics used to

The independent-samples t-test was used
to detect a significant difference between mean
profit earned by fishers with outboard engines
and mean profit earned by fishers without outboard engines. Analysis of variance under a
general linear model, in which the errors are
distributed normally, was used to test for any
differences in the mean profit earned by fishers in all the ADP zones. The analysis focused on
fixed effects of profitability of fishers within the
zones. SPSS Statistics version 20 (IBM, Bethesda, Maryland) was used for the analysis.
Results
Socioeconomic characteristics of ishers
Presented in Table 2 are the socioeconomic
characteristics of fishers interviewed. The
sample showed that all are male (100.0%)
and the majority are married (98.5%). Almost
half of those who are married have one wife
(45.5%). The majority of the fishers are within the age bracket of 23–50 years (71.5%) and
have completed at least primary education
(76.5%). In terms of household size, 48.5%
of the fishers have between 11 and 20 family
members. The primary source of livelihood is
fishing during the dry season (91.0% of fishers) while during the wet season, about 52.5%
of fishers were actively involved in both fishing and farming.
Fishing operations
The majority of fishers interviewed had more
than 10 years (95.9%) of fishing experience
(Table 3). Most of the fishers are full-time
fishers (54.0%) and have at least one wooden canoe. Only 24 fishers (12%) have canoes
with outboard engines. Gill nets of various
sizes are used. Both family and hired labors
are also used.
Some fishers fished year round, primarily in the Benue and Taraba rivers, with their
fishing activity being more concentrated during the dry season (November–March), which
is the main fishing season. Other water bodies that are fished include the Bali, Dongai,
and Suntai rivers. Fishers also fish in natural
ponds that can be as large as 5–50 ha and
owned by families of the ruling or royal houses/community leaders. These natural water bodies were fished between January and
March or between April and May. Examples
are Bemba Lake, which is more than 4 km2 in
size, and Marami Lake and Goje Pond, which
are 4 km2 in size in the Wukari LGA.
Major fish species caught include Tilapia
spp., Nile Tilapia Oreochromis niloticus (also T.
nilotica), Clarias spp., Nile Perch Lates niloticus,
Aba Gymnarchus niloticus, Bayad Bagrus bajad,
and Synodontis spp. Others reported by a few of
the fishers include Moon Fish Citharinus citharus, African Bonytongue Heterotis niloticus,
Heterobranchus spp., Labeo spp., Elongate Tigerfish Hydrocynus forskahlii, Torpedo Robber
Alestes macrophthalmus, clupeids, Protopterus
spp., Polypterus spp., Electric Catfish Malapterurus electricus, and Mormyrus spp.
Household value of isheries resources
In the 16 LGAs, located within the four ADP
zones, there are more than 52,535 fishers
households registered with the Taraba State
Ministry of Agriculture and Rural Development who earned their living solely from
inland fisheries (TSADP 2010). Fisheries resources are valuable to the fishers based on
the benefits derived. According to the fishers
interviewed, income generated from fishing
was used mainly for meeting basic needs such
as food, health care, and clothing. Fishing gear

streams have open-access fisheries that are
mainly under the control of the state and federal departments of fisheries. The ruling or
royal house families own and manage the natural ponds and lakes. The main interaction that
exists between the multiple users of the water
bodies in Taraba State is that of compromise,
not conflict.
During the fishing season, fishers from
other fishing villages are invited to fish and required to pay a tax to fish in the natural ponds
and lakes. Fishers from the village and other
villages that are not owners of the ponds must
pay to fish. A group of fishers could be asked
to pay as much as ₦300,000 or more to set gill
nets to fish in a pond or lake owned and managed by the ruling or royal house families.

When a ruling or royal house family charges
₦300,000 to fish in their pond or lake for 3
months, the amount charged is shared among
the group of fishers. The fishers are of the opinion that, in general, a payment of ₦15,000 per
fisherman is too much. Traditional management of the ponds and lakes by the ruling and
royal houses families has improved over time.
Since 1991, owners of the ponds have learned
from the Taraba State MANR Divisional Fisheries Office to remind fishers to adhere to fisheries laws before the start of every fishing season. An example is that they are not allowed to
use undersized mesh sizes, chemicals, or plant
poisons.
Despite the presence of traditional (ruling and royal house families) and government
management system, overfishing and destructive practices still occur in some of the water
bodies. The information collected through interviews with the divisional fisheries officer
of the Taraba State MANR Divisional Fisheries
Office and some executive members of fishermen cooperative societies reveal that these destructive practices include unrestricted numbers of fishers using gill nets and drag nets, use
of chemicals such as Gamalin 20, unrestricted
draining of pools, and erection of permanent
barriers to trap migratory fishes. Members of
fishery cooperative societies in Bali keep watch
over the waters and have arrested offenders
for polluting the waters with chemicals. These
offenders were sent to court, and officers of the
Taraba State MANR Divisional Fisheries Office
prosecuted them.
Taboos and beliefs
From the 200 fishers interviewed, it was observed that fishers believe in several taboos
and some of them are targeted at females. For
example no woman menstruating is allowed to
touch the nets or come into the canoe. Other
taboos exist: slippers or shoes are not allowed
in the canoe, some fishers believe that they
should wash their face and feet before entering
the canoe, the use of charms and drunkenness
are not allowed when fishing, eating Heterobranchus spp. is believed to cause yellow fever.
The only taboo aimed at preserving the fish
species and environment of the water bodies
is that fishers are forbidden from using chemicals to harvest fish.
Challenges of ishers
Major complaints of the fishers interviewed
included the lack of funds to buy fishing gear
and lack of government assistance. Moreover,
fishers also complained that fisheries officers
are neither available to patrol water bodies to
enforce fishing regulations nor to train fishers.
Other challenges encountered by the fishers
that were mentioned during the interviews include the constant receding of water levels due
to the drying up of Benué River and insufficient
fish to catch. Some fishers complained of being
chased by hippopotamuses while fishing in
Benué River. According to the fishers, the use
of traps and fences was considered a possible
reason for the reduction in fish catch because
both migratory adult spawners and fingerlings
are caught.
Test of hypothesis
The results of the analysis revealed that there
was significant difference between mean profit
earned by owners of canoes with outboard engines and owners of canoes that did not have
outboard engines (t = 2.560, df = 27.200, P =
0.016). Profitability analyses across ADP zones
were also significantly different (ANOVA: F =
2.751; df = 3, 196; P = 0.044).
Discussion
For those in Nigeria that live near water bodies,
fishing is a major source of livelihood (Townsley 1998; Fregene et al. 2003; FAO 2015). Fish
caught provide food security and income. The
income generated from fishing is used to purchase food, housing, education, assets, and
health for the fishing households (Chiwaula
and Witt 2010).
Several other studies have revealed that
the average net margin for fishers with outboard engines was higher than for those
without (Fregene et al. 2003; Olademeji et al.
2014). But contrary to this study, some studies found that the fishers without outboard
artisanal fisherman in taraba state, nigeria
engines earned a larger profits because they
had higher returns on investment, as well as a
higher operating margin, than fishers with outboard engines (Olademeji et al. (2014). Inoni
and Oyaide (2007) also observed that although
small-scale fishing was found to be profitable,
the low operating margin, particularly among
fishers with outboard engines was a concern,
due to the high cost of production, dwindling
catches, and the need to safeguard the livelihood of fishing-dependent people in coastal
communities.
Community involvement in governance
Scudder and Connelly (1985), cited by Ita
(1993), identified two major categories of
management of traditional riverine fisheries in
the Amazon basin, middle Zambezi River, and
Kafue floodplains. One management category
consisted of inadvertent or unintentional management strategies, such as water tenure, ritual prohibitions, taboos, and magic. The other
management category consisted of intentional
strategies that include gear restrictions, closed
seasons, and floodplain intensification (increased ownership). Both these management
categories are common in the northern states
of Nigeria. However, Ovie and Raji (2006) observed that mixed systems involve the participation of both the unintentional management
category, as represented by the traditional
ruler and royal house families, and the intentional management category, represented by
the modern government administrations that
operate in fishing communities.
Ita (1993) reported that in some northern
states, such as Sokoto Rima and Kano, flood
ponds and stagnant pools of seasonal rivers
belong to all the communities, and permission
to engage in fishing is often announced by the
sarkin ruwa or the “chief of the fishermen,” who
has the power to authorize and stop fishing in
different ponds and at appropriate times. This
approach, although similar to closed seasons
found in government management approaches, is directed more at protecting the interests
of part-time fishers who engage in full-time
farming during the rainy season and return to
fishing at the end of the farming season. The
155
focus of this restriction is not for conservation
of fisheries resources, but to ensure that every
member of the community has an equal chance
of benefiting from the resource.
Challenges of isheries resources
conservation and ish data
The conservation of fisheries resources becomes a challenge when there is a lack of alternative sources of livelihood during the dry season. An increase in the number of fishers will
invariably result in smaller catches per fisher
and therefore a lower profit margin. AragónNoriega (2009) is of the opinion that in an area
that has a well-established fishing tradition,
enforcing a permanently closed season could
produce severe social disturbance. The enforcement of fishery laws and regulations requires
determined political commitment on the part of
government and adequate legislative and financial support (Amiengheme 1993).
Despite the importance of fish catch data,
funding for the development and maintenance
of fisheries statistics at the federal level has
been decreasing since 1992, while demand for
fish catch data is growing. Fishery data are not
available in nearly all of the states in Nigeria,
likely due to poor funding and insufficient personnel to collect and collate such data (NAERLS
and NPAFS 2010). Inadequate fisheries statistics collected especially for inland fisheries are
from many unlicensed, part-time, and seasonal
operators (Fregene and Bamiduro 2006). The
Federal Ministry of Agriculture and Rural Department (2012) recorded 11,862 metric tons
of fish production for Taraba State. This is quite
low based on the available water bodies in the
state. Chiwaula and Witt (2010) observed that
there is an acute lack of relevant research and
data about the socioeconomic value of smallscale fisheries to fish-dependent households
and communities. As a result, communities
depending on artisanal fisheries are often marginalized or ignored in national and regional
development policies.
Recommendation
The artisanal fisheries require a dynamic partnership approach that will use traditional skills,
156
fregene
indigenous knowledge, local institutional arrangements, and resource stewardship. Jallow
and Njie (2004) therefore advised that these
elements be complemented with national governments, providing an enabling environment,
scientific advice, legislation, monitoring, and
control, and surveillance, among other types
of assistance. Capacity building among both
government personnel and local stakeholders
must therefore be developed and promoted.
Government officials are limited in number and lack mobility and finances to enforce
regulations. Executive members of the existing
fishery cooperatives, however, can further be
empowered to monitor, control, and conduct
surveillance on water bodies. This is because
they are located in every LGA and have members in almost all the fishing communities.
They will be more committed because the water bodies provide their livelihood.
A critical issue is the need for the Nigerian
government to adequately fund data collection
for fish catches and socioeconomic variables
(Fregene and Bamiduro 2006). Timely and
accurate information is essential for effective
management. In a situation where the government fails, nongovernmental organizations,
together with executive members of livelihood
associations, for example, have been effective
in aquaculture data collection.
There is a need to enlighten traditional rulers and members of the fishing communities
to minimize conflict and increase the understanding of the value of the fisheries.

Abstract.—A field study was conducted to understand the livelihoods and
poverty incidence among fishers and nonfishers (farmers and farm laborers) residing around the Hirakud reservoir in Odisha State, India. About 14,500 fishers in
159 villages are dependent on Hirakud fisheries. The fishers belonged to several
socially diversified groups, including traditional fishing castes (42%) and agricultural and artisanal castes. Both fisher and nonfisher households had diversified
occupational profiles. The literacy rate among fishers was 62%, as compared to
nonfishers (83%). While housing, per se, did not differ, basic amenities (sanitation, electricity, and drinking water) were far better among nonfishers and correlated significantly with higher educational status and expenditures for health and
well-being. Forty-two percent of fishers belonged to the fishing caste and most of
the nonfishers (74%) belonged to other castes (i.e., not part of the fishing, agriculture, or artisanal caste). Inequality and poverty studies revealed that fishers were
poorer than nonfishers as per both the standards of India’s Planning Commission
and the World Bank. This finding was also supported by the results of a poverty
gap index and a Watts index, which highlighted a greater depth of poverty among
fishers than nonfishers. The incidence of extreme poverty was 21% among fishers
and 3% among nonfishers when using the cut-off per capita expenditure of purchasing power parity (PPP) US$1.25/d, and the incidence rose to 64% and 34%,
respectively, when the cut-off line is PPP $2/d. Interestingly, as per Gini index values, income inequality was greater among nonfishers (0.215) and the average rural Indians (0.339) than the fishers (0.158).

Introduction
palita et al.
The development of fisheries in reservoirs is
a holistic function of ecology, fisheries, socioeconomics, and governance, with technology
playing an intermediate role. Only a few studies have addressed this issue holistically, as
most have studied only fisheries and ecology.
Very little information exists about the reservoir fisheries in Odisha; details like fisheries
management systems, fish production trends,
utilization patterns, and socioeconomic status of fishing communities are not available
as per the literature review. As per the survey
data of the State Fisheries Department, Odisha has a total water spread of 256,000 ha in
the form of major, medium, and minor reservoirs, and a total of 1,442 units of reservoirs
were identified, covering an area of 197,198
ha, which contribute to the fish production
of the state. There are three large reservoirs,
Balimela in the district of Koraput (19,440
ha); Hirakud in the Sambalpur, Jharsuguda,
and Bargarh districts (71,963 ha); and Rangali in the district of Dhenkanal (28,000 ha). Annual fish harvest from the Hirakud reservoir
is 4,798 metric tons (2012–2013) with a yield
of 84 kg/ha, which is consistent with the state
average productivity of 83 kg/ha (computed
by the authors from the compiled survey
data). This paper focuses on the livelihoods,
poverty, and inequality of fishers and nonfishers of the Hirakud reservoir in the region of
Odisha. Nearly 14,500 fishers depend upon
this reservoir for their livelihood. Odisha has
significant reservoir resources; the extent of
their use for fisheries and the potential for
creating sustainable livelihood in distressed
conditions and remote areas need to be understood. The socioeconomic status of fishing communities around the dam plays a very
significant role in the development of reservoir fisheries. Livelihood study and analysis
can reshape a program focusing on the livelihoods of people, and help make clear how a
program fits in with livelihood strategies and
how people’s livelihoods are being enhanced
or constrained. On this basis, recommendations for improvement interventions can be
made (Ashley 2000). Poverty estimates will
act as vital input to design, monitoring, and
implementation of appropriate antipoverty
policies. It is in this context that the following
specific objectives are undertaken.
Objectives
The specific objectives of the study are (1) to
understand the social, economic, and occupational profile of fishers and nonfishers; and (2)
to analyze the inequality and poverty among
fishers and nonfishers.
Methods
The present study was conducted in the Hirakud reservoir region of Odisha by the authors. The reservoir is divided into six geographical sectors. During the presurvey visit,
information regarding the total number of
villages in all sectors on the periphery of reservoirs, their fisher population details, religions, and caste details were assembled to
build the sampling methodology. Five villages
were selected representing all the stretches of
the reservoir for study. Fishers’ population of
the village, major fishing activities, and fishers’ membership in the cooperative society
were also considered during the selection of
villages for study. First-hand observations
by transect walks through the villages in the
reservoir periphery and interviews with key
informants with the aid of a check list, a semistructured interview with respondents, and
a focused group discussion were carried out.
The sample size was 190, including fishers
(120) and nonfishers (70).
Here, an independent sample t-test was
used to differentiate among fishers and
nonfishers on the basis of variables of continuous scale (age, family size, education,
housing facilities, and housing amenities). A
Mann–Whitney U-test was used to compare
differences between two fishers and nonfishers when the dependent variable is either
ordinal or continuous but not normally distributed (family type [e.g., nuclear family or
joint family]; caste type [e.g., fishing caste,
agricultural caste, artisanal caste, and other
castes]).

Results
Housing facilities and household amenities
To develop an index for housing facilities, four
parameters were considered: house type, ownership status, house area, and cooking place.
These four parameters were rated on a 4-point
scale, with highest rank given to the better facilities. The combined scores were standardized
to make them unit-free. To develop a household
amenities index, five variables were selected
and rated on a 3-point scale, including sanitation facility, drinking water, fuel used for cooking, lighting source, and mode of transportation.
The same procedure applied for a housing facilities index was adopted to develop a household
amenities index.
Inequality and poverty
Poverty analysis tools.—The extent of poverty was based on the monthly per capita expenditure of fishers and nonfishers. The poverty line was fixed as per the World Bank (i.e.,
poverty head count ratio at US$1.25/d, which
is equal to Rs 19.8 in Indian currency [rupees;
World Bank 2005] and poverty head count ratio at $2/d, which is equal to Rs 31.8 in Indian
currency (World Bank 2005). A poverty line at
$1.25/d indicates extreme poverty and a poverty line at $2/d was used to compare the status of
poverty at the extreme poverty line ($1.25/d). A
comparative study of the extent of poverty was
also done using the poverty line value of India’s
Planning Commission (i.e., Rs 27.2/d [This is an
Indian standard of estimating poverty line.]). A
conversion factor was used to convert U.S. dollars to Indian rupees and the conversion factor
for India is 15.9 (Average of conversion factor
data of World Bank [2013] data for the years
2011, 2012, and 2013 has been considered for
analysis by author.).
Poverty indices.—For the analysis of poverty, the head count ratio, poverty gap index, Lorenz curve, Gini index, and Watts index (Table
1; Haughton and Khandker 2011, Chapter 4)
were used based on the consumption expenditure of fishers and nonfishers, but the Gini
index was calculated from both income and
expenditure. All these indices have been compared with the World Bank data (Haughton
and Khandker 2011, Chapter 4).
161
Social parameters
In the Hirakud reservoir region, most of the
fishers (58.3%) and nonfishers (65.7%) are
middle aged (i.e., 35–59 years). The mean age
of fishers (43.36 years) was not significantly
different from that of nonfishers (41.53 years).
The majority of nonfishers (55.7%) had secondary education (6–10 years of education),
whereas 38.3% of fishers were illiterate. There
was a significant difference between the education level of fishers and nonfishers. Nearly
88% and 98% of fishers and nonfishers, respectively, belonged to nuclear families. Most
of the fishers (73%) and nonfishers (88%) had
a family size of less than five members. Nonfishers had better houses with more amenities
than fishers (Table 2).
Caste type
Table 3 depicted the caste profile of people
residing around the Hirakud reservoir. The
people in the periphery of the reservoir belong to different caste types, like fishing caste,
agricultural caste, artisanal caste, and other
castes. Forty-two percent of fishers belonged
to the fishing caste, and most of the nonfishers (75%) belonged to other castes. A Mann–
Whitney U-test indicated that the P-value was
0.000, and there was a significant difference
between fishers and nonfishers with respect
to caste.
Economic proile
Occupation.—Fishers who live in the periphery region of the Hirakud reservoir had
four types of occupation: (1) fishing only; (2)
fishing and olericulture; (3) fishing and labor;
and (4) fishing, olericulture, and labor (Table
3). The primary occupation was fishing and
olericulture (45.8%) followed by only fishing
(42.5%; Table 4). Only a few fishers were also
employed in both olericulture and labor.
Most nonfishers were involved in agriculture (31.4%) and private industry (31.4%; Table 5). Many factories have been developed in
the Sambalpur, Jharsuguda, and Bargarh districts, so many respondents were involved in

Expenditure pattern.—A comparative
study of the monthly per capita expenditure
shows how fishers, nonfishers, and rural Indians earn money to have the ability to provide
a varied diet to their family. Table 6 depicts
that monthly per capita expenditure of fishers
as Rs 976, which is less than that of nonfishers (Rs 1315) and rural Indians (Rs 1189).

on nonvegetable items among nonfishers was
more than that of fishers and average rural Indians. Nonfishers were spending more on education (8%) than fishers (4%) and average
rural Indians (4%). Expenditures on health
for fishers and nonfishers were 4% and 5%,

Inequality and poverty
Extent of poverty of occupational groups in
the reservoir region.—“Poverty has been described by the International Bank for Reconstruction and Development (IBRD 2001) as a
situation of ‘pronounced deprivation in wellbeing,’ and being poor has been described as
‘to be hungry, to lack shelter and clothing, to be
sick and not cared for, to be illiterate and not
schooled.’ Poor people are particularly vulnerable to adverse events outside their control.
They are often treated badly by institutions of
the state and society and excluded from voice
and power in those institutions” (IBRD 2001).

the number and proportion of people living
below the poverty line at national and state levels separately for rural and urban areas. It esti-

mates poverty based on a large sample survey
of household consumption expenditure carried
out by the National Sample Survey Organization
after an interval of approximately 5 years. The
percentage of persons below the poverty line
in 2011–2012 has been estimated as 25.7% in
rural areas, 13.7% in urban areas, and 21.9%
for the country as a whole. As per the Planning
Commission’s poverty line, there were more
fishers (38%) falling below the poverty line
than nonfishers (23%), and their average annual per capita expenditure (Rs 7,323) is less than
that of nonfishers (Rs 8,770) (Table 7).
Lorenz curve and Gini index
For a comparison of the distribution of income,
a Lorenz curve was drawn for fishers, nonfishers, and rural Indians based on the household
per capita income. It shows the relationship between the percentage of the population and the
percentage of per capita household income. For

population has 13.3% of the total household
per capita income (summation of numbers
1 and 2; Table 8), whereas the upper 20%
of the population has 27.09% of the income
(summation of numbers 9 and 10; Table 8).
For nonfishers, the bottom 20% of people
has only 10% of the income, whereas the top
20% of population has 38% of the income
(summation of numbers 1 and 2 and summation of numbers 9 and 10, respectively; Table
8. This shows that there is less inequality or
variation in the distribution of the income of
fishers than that of the nonfishers and rural
Indians (Figure 1).
The inequality in income distribution can
be better understood from the values of the
Gini index. It ranges in value from 0 (perfect
equality) to 1 (perfect inequality). The Gini index value for fishers (0.137) is less than that
of the nonfishers (i.e. 0.280). This Gini index

The poverty gap index, which ranges from 0
to 1, with a value of 1 indicating that all individuals are below the poverty line (Table 1), indicates that the incidence of poverty for nonfishers (0.002) is less than that of fishers (0.030),
which is less than that of rural Indians (0.075)

be overcome by using a Watts index, which is
computed by using antilogs. The results of the

Discussion
This study focused on the socioeconomic aspects and occupational profile of fishers and
nonfishers of the Hirakud reservoir region and
also compared the inequality and poverty of
fishers and nonfishers. The study found significant differences in economic characters between fishers and nonfishers, with fishers usu-

livelihood and poverty among fishers and nonfishers in india
ally being more poor than nonfishers. Although
nonfishers had a higher level of inequality in
income distribution than fishers, this was due
to the diversified occupational profile of nonfishers (farm labor, farming, small business,
and private job), resulting in a high range of
income variation.
Nonfishers were found to be richer than
fishers with a better standard of living. It was
difficult to collect the actual income information of fishers and nonfishers through the
household survey. To get the actual income
details of fishers, income calculated from the
daily fish catch details of each fisher could
be used but may not be representative of the
household. Furthermore, it was not possible to
get the actual income details of nonfishers due
to data limitation. Further efforts should be
made to get more complete income information on fishers and nonfishers. This information about the livelihood of fishers can be used
by policymakers, administrators, researchers,
and client agents to form better livelihood
strategies. Poverty estimates can also be helpful as a vital input to design, monitor, and implement appropriate antipoverty politics.

Abstract.—Freshwater capture fisheries in the lower Mekong River basin
(LMRB) contribute from 17% to 22% of the officially reported global inland capture
fisheries catch. Several dams have been proposed on the Mekong River and its tributaries that will impact these fisheries. It has been estimated that the harvest from
freshwater capture fisheries in the LMRB could decline by 880,000 metric tons in
2030 if all dam construction proceeds as planned.
To reflect the consequences of lost fisheries in the LMRB, we reviewed existing
data and calculated the contribution freshwater fisheries make to human protein,
nutrient, and mineral requirements. We further calculated how much additional
land and water would be required to replace lost fish protein in the LMRB with four
other animal protein sources: beef, chicken, pork, and milk.
Replacing fish with beef was found to be the most costly; to replace the fish
harvest in the LMRB estimated to be lost due to dam construction with beef would
require 3.6% of the total discharge of the Mekong River, which is equivalent to a
28% increase in water withdrawal compared to current levels.

lymer et al.
To replace all of the fish harvested in the LMRB with beef would require an additional 395,048 km2 of land (equivalent to 65% of the total area of the Mekong River
basin) and a 63% increase in water withdrawal. Replacing the fish with chicken would
require the least additional land and water but still would require more than 36,000
km2 of land and an 8% increase in total water withdrawal from the Mekong River.
The replacement analysis for the fish consumed in the four countries demonstrates that Cambodia would have the highest requirements in terms of increased
use of land and water followed by Thailand and Vietnam, whereas Laos have lower
requirements but would still need to increase its land use significantly.
Overall, our analysis shows that freshwater fish is a highly valuable source of
animal protein and micronutrients in LMRB. Replacing the fish protein with other
sources of animal protein will require a substantially higher use of land and water.
Introduction
Freshwater capture fisheries in the lower Mekong River basin (i.e., Cambodia, Laos, Thailand and Vietnam) are reported to be between
2.0 and 2.6 million metric tons (van Zalinge
et al. 2004; Hortle 2007; ICEM 2010; MRC
2014), which is probably an underestimation
of actual catch (Hortle and Bamrungrach 2015;
IFREDI 2013; Lymer et al. 2008; Coates 2002).
This makes it the largest connected freshwater fishery in the world and corresponds to
between 17% and 22% of total official global
inland capture fisheries catch (FAO 2014c). In
the countries of the lower Mekong basin, freshwater fish are a crucially important source
of nutrition, with Cambodia and Laos having
among the highest fish protein consumption of
nonisland states (FAO 2014b; FAO 2014d; Hall
et al. 2013). These fish and fish products are
often culturally preferred and easily accessed
by the poor (Belton and Thilsted 2014).
There are currently 11 proposed dam construction projects in the lower Mekong basin
(ICEM 2010; Orr et al. 2012) that will have
significant effects on the quality and quantity
of harvestable resources from inland fisheries
(WorldFish 2013). Increasing human population and demand for energy are driving these
projects. It is estimated that only 5% of the potential hydroelectric power in the Mekong basin is currently exploited; this 5% has an economic value of US$235 million per year (MRC
2005). However, it has been estimated that a
large part of the fish harvest in the Mekong
River and the associated nutritional and social benefits will be lost due to dam construc-
tion (Ziv et al. 2012; Dugan et al. 2010). Baran
(2010) estimated that freshwater capture fisheries in the lower Mekong River basin could
decline by 880,000 metric tons in 2030 if dam
construction proceeds as planned.
If there was a decline in freshwater capture fisheries due to dam construction, fish
protein would have to be replaced by another
source to maintain current consumption levels
and meet the nutritional requirements of the
human population. Livestock production is the
other important source of protein in the countries of the lower Mekong basin (FAO 2014b),
and in 2011, the average daily per capita consumption of protein for these countries combined was 4.9 g for freshwater fish and 9.6 g for
bovine, pig, and poultry meat (Table 1).
Freshwater fish is a crucial source of protein for the most poor and vulnerable people
because it requires much lower investments
compared to livestock production and it is estimated that about 1 × 109 people worldwide
rely on fish as their primary source of animal
protein (FAO 2000). The rapid population

freshwater fisheries harvest replacement estimates
growth, urbanization, and increase in the percapita income in the Mekong region will lead
to a higher demand for animal products; the
demand for meat is expected to increase by
more than 140% between 2005 and 2050 in
East Asia (China excluded) (Alexandratos and
Bruinsma 2012).
While freshwater capture fisheries have
a negligible footprint on land and water, livestock is an important user of these resources
and can compete with other sectors for land
(e.g., industry, housing, and crop production).
On a global scale, livestock production uses
about 30% of the global ice-free land (25%
through grazed land and 5% through feed
crops; Monfreda et al. 2008; Ramankutty et al.
2008) and 29% of the total agricultural water
(Mekonnen and Hoekstra 2012). The replacement of freshwater fish protein by livestock
protein would, therefore, be accompanied by
environmental costs.
The objective of this study was to assess
the environmental cost in terms of land and
water use if freshwater fish proteins were replaced by livestock proteins in the four countries of the lower Mekong River basin.
Method
Nutrition components and requirements
To determine the contribution of freshwater
fish to protein, calcium, iron, zinc, and vitamin A to the nutritional requirements of the
four countries (Thailand, Vietnam, Laos, and
Cambodia) in the lower Mekong River basin,
we calculated the mean freshwater fish composition (FC) from the literature. To establish
the nutrient requirements of the population
in the lower Mekong River basin, the population of the four countries was separated by
country and by gender into 22 age categories
spanning 5-year intervals (UN 2014). Each
age category was multiplied with the nutrient requirements for that age and gender category, for protein (WHO 2002), calcium, iron,
zinc, and vitamin A (WHO and FAO 2004). The
estimated freshwater fish consumption per
country (FishC) was calculated from fish consumption data from the four countries (Need-
171
ham and Funge-Smith 2014) and human population (UN 2014) as follows:
(
FishCcountry x = Per capita fish consumptioncountry x
(
× % freshwater fish consumedcountry x
(
× Populationcountry x
)
)
)
(1)
The contribution of the fish consumed
to the four countries’ nutrient requirements
(CFFnutrient) was calculated using mean
freshwater fish composition for small freshwater fish (SSF), large freshwater fish (LFF), or
average of SFF and LFF, as follows:
CFFnutrient = sum (NR countries ) /sum (FishCcountries )
× FCnutrient
where
(2)
CFFnutrient = contribution of freshwater fish to
nutrient requirements of the total populations (by gender) in countries (nutrients =
protein, calcium, iron, zinc, and vitamin A)
NRcountry = nutrient requirements per country
(country = Cambodia, Laos, Vietnam,
Thailand)
FishCcountry = freshwater fish consumption per
country (country = Cambodia, Laos, Vietnam, Thailand)
FCnutrient = mean freshwater fish composition
(nutrients = protein, calcium, iron, zinc,
and vitamin A)
Replacement scenarios
To estimate the land and water requirements
to replace freshwater fish with livestock protein sources in the region, three different
scenarios were used: (1) the replacement
quantity of proteins for the total harvest of
freshwater fish (FishH) in the Mekong River
basin freshwater fish was calculated based on
a 2 million metric tons estimated total harvest
of freshwater fish (MRC 2014), (2) the replacement quantity of proteins for the freshwater
fish consumption (FishC) of the four countries
in the lower Mekong River basin, and (3) the
replacement quantity of proteins for the potential loss of Mekong River basin harvested
fish (FishL) from dam construction estimated
to be 880,000 metric tons (Baran 2010). For
172
lymer et al.
the three scenarios, FishH, FishC, and FishL,
the average protein content of freshwater species (FCprotein) was used to convert fish weight
to grams of protein.
Livestock data: production, land, and water
requirements
Livestock data for four alternative protein
sources (beef, chicken [including meat and
eggs], pork, and milk [from cows]) were obtained from the Global Livestock Environmental Assessment Model (GLEAM; Gerber et al.
2013; MacLeod et al. 2013; Opio et al. 2013).
GLEAM is georeferenced; therefore, all data
can be spatially disaggregated at region, country, or intracountry level. Data can also be disaggregated by species, commodities, and production system.
Production (kilograms of protein) and
land use (km2) for the four alternative protein sources were extracted from GLEAM by
country and by protein source. Land use was
derived from the quantity of feed consumed by
livestock. The ratio between land use and production was computed to obtain the land use
requirements of 1 kg of protein for the four alternative protein sources. Water requirements
were obtained from Mekonnen and Hoekstra
(2012).
Land and water requirements for protein
replacement
For the total fish harvest (FishH) and fish harvest lost (FishL) to dam construction , the Mekong River basin fish protein environmental
replacement quantity for the four alternative
protein sources, in terms of land (GLEAM model) and water (Mekonnen and Hoekstra 2012),
was calculated as follows:
Basin replacement quantity landprotein source
(
= Land requirement protein source region average
)
× (Fish protein [kg ])
Basin replacement quantity waterprotein source
(
= Water footprint protein source
× (Fish protein [kg ])
(3)
)
(4)
The Mekong River basin equivalents
(MRBeq) per alternative protein source were
calculated by dividing the respective Basin
replacement quantity landprotein source with the
total Mekong River basin area (795,000 km2;
FAO 2014a). The change in land use (↑Land
use) was calculated by dividing Basin replacement quantity landprotein source by the current total land use. Basin replacement quantity waterprotein source was divided by water withdrawal
(62 km3; FAO 2014a) or total discharge of the
Mekong River into the South China Sea (475
km3; FAO 2014a) and presented as change in
water withdrawal compared to current level
(↑WW) and fraction of total discharge of Mekong River (TDMR).
For freshwater fish consumption per country (FishC), the country fish protein environmental replacement quantity (i.e., land and
water quantity) per alternative protein source
is calculated as follows:
Country replacement quality landprotein source country
= Land requirement protein source country
× Fish protein ( kg )country
Country replacement quality waterprotein source country
= Water footprint protein source
× Fish protein ( kg )country
(5)
(6)
Fish protein environmental replacement
quantities in country area equivalents (Country eq.) per alternative protein source and
country was calculated by dividing the respective Country replacement quantity landwith the total country area (Laos
protein source
236,800 km2; Thailand 513,120 km2; Cambodia 181,035 km2; Vietnam 331,210 km2; FAO
2014a). The change in land use (↑Land use)
was calculated by dividing Country replacement quantity landprotein source with the current
total country land use. The Country replacement quantity waterprotein source was divided by
total country water withdrawal (Laos 3.96
km3/year; Thailand 57.30 km3/year; Cambodia 2.18 km3/year; Vietnam 82.03 km3/
year; FAO 2014a) and presented as change in
water withdrawal compared to current level
(↑WW).

Results
The estimated freshwater fish composition
(FC) highlights that small freshwater fish species (SFF) have a much higher mean composition of all the minerals (759.13 mg Ca, 9.70 mg
Fe, and 5.65 mg Zn) and vitamin A, whereas the
large freshwater fish species (LFF) have higher
mean protein content (18.49 g; Table 2).
The total consumption of freshwater fish
per country (FishC) across the four countries is
highest in Thailand (750,373 metric tons), followed by Cambodia, Vietnam, and Laos (Table
3).
The sum of the four countries’ nutrient
requirements (Sum [NRCambodia, NRLaos,
NRVietnam, NRThailand]) of the population in
the lower Mekong River basin show that a total of 3 million metric tons of protein is needed
each year and that the female human population needs relatively more iron than the male
population (Table 4)
The contribution of the freshwater fish
consumed to human nutrition in the four countries in the lower Mekong River basin was significant (>10%) for all the assessed nutrient
173
components (Table 5) and especially for small
freshwater species that contribute greatly to
vitamin A (73%) and zinc (49%) requirements.
Freshwater fish protein contributes between
11% and 12% of total protein requirements of
the human population.
Freshwater fish consumption per country
(FishC) is 33% of the total of the five assessed
animal protein sources produced in the four
countries (356,005 metric tons of fish consumed divided by 1,063,153 metric tons of
fish, chicken, pig, beef, and milk; Table 6). Fish
protein production (FishH) in the four countries is extremely high and second only to pig
protein production (Table 6). Fish protein loss
due to dam construction (FishL) was also high
and greater than protein production from beef
and milk (Table 6).
Currently, beef and pig production have
the highest land uses in the four countries, but
chicken production also has high land use in
Thailand (Figure 1).
The average land requirements were highest for beef (1.130 m2/g protein) followed by
milk, pig, and chicken; the global average water
requirements was also highest for beef (112 L

To replace the fish harvested (FishH) in the
Mekong River basin with beef would require
395,048 km2 of land, which is equivalent to 65%
of the area of the total Mekong River basin (Table
8) and would require 8% of the total discharge
of the Mekong River, which is equivalent to a
63% increase in water withdrawal compared
to current levels (Table 9). Increasing production with the current shares of alternative protein sources (current mix, Table 9) in the region
would result in an increased land requirement
of 64,739 km2 and 18 km3 of water.
The replacement requirements for the fish
harvest estimated to be lost (FishL) due to dam
constructions in the Mekong River basin with
beef would be 173,821 km2, which is equivalent
to 28.7% of the area of the total Mekong River
basin (Table 8). Further, replacing the loss of fish
175
harvest (FishL) with beef would require 3.6% of
the total discharge of the Mekong River, which
is equivalent to a 28% increase in water withdrawal compared to current levels (Table 9).
Increasing production with the current shares
of alternative protein sources produced in the
region (current mix) would result in an area requirement of 28,485 km2 and 8 km3 of water.
To replace the freshwater fish consumed
per country (FishC) within the countries in the
Mekong River basin with beef would require
165,048 km2 more land in Cambodia, equivalent to 91.2% of the country’s area; 152,545
km2 of land in Thailand, equivalent to 29.7%
of the country’s area; 93,902 km2 of land in
Vietnam, equivalent to 28.4% of the country’s
area; and 21,396 km2 of land in Laos, equivalent to 9.0% of the country’s area, (Table 10;
Figure 2). It would also require an increase in
water use compared to current levels of 577%

quirements in the lower Mekong River basin.
This contribution is similar throughout the developing world. Developing countries produce
more than 95% of total inland fish harvest,
with much of that production being locally
consumed (FAO 2010).
Replacing fish as a protein source with
other animal protein sources would require
allocation of additional land and water resources, with some countries needing to allocate more due to their higher reliance on fish
for protein. The loss in fish harvest due to the
proposed dam construction in the Mekong
River main stream will incur severe requirements in terms of land and water to replace
the fish protein (Figure 3). Our analysis show
higher replacement requirements than previous estimates (Orr et al. 2012); for example,
the land requirement we calculated (current
mix) is 402% (minimum) to 117% (maximum)
of Orr et al.’s (2012) assessment. These additional resource requirements may however be
reduced through technological advances and
improved resource-use efficiency. Land and
water use per protein source for the assessed
protein sources in the four countries differs
substantially from those in OECD (Organisation for Economic Co-operation and Development) countries (Figure 4).
In understanding the replacement requirements for the fish harvested and consumed and potentially lost, one needs to consider how the additional quantity of protein
from local production of terrestrial animals
will be met. Replacing fish protein with livestock protein can be met in different ways (e.g.,
increasing the number of livestock, which will
demand more resources in terms of land and
water resources; improving animal productivity, which will demand more water [surface and
groundwater], or increasing imports of animal
protein, which will result in lower additional
land requirements. Land and water resources
are however not the only constraints or environmental impacts to consider when replacing
aquatic protein with terrestrial protein. Changes in food production patterns have important
implications for greenhouse gas (GHG) emissions and carbon, nitrogen, and phosphorus
cycles. Livestock have an important contribu-

tion to GHG emissions in East Asia (more than
1 × 109 metric tons CO2 equivalent; Gerber et
al. 2013), whereas GHG emissions from inland
fisheries can be assumed to be negligible as
fishing practices within the region are mostly
traditional, based on manual labor and limited use of motorized boats (Welcomme et al.
2016). Regarding land use, emission intensities from livestock largely vary among species
and commodities, and the level of productivity
and types of practices also have a huge effect
(Gerber et al. 2013; Pierrehumbert and Eshel
2015). Replacement requirements in terms of
GHG emissions would, thus, differ significantly
according to the livestock commodity used as
a replacement and changes in current produc-

tivity and practices, but also would depend on
changes in the aquatic environment (Barros et
al. 2011; Raymond et al. 2013).
Further, there will be effects on biodiversity and human health (Goedkoop et al. 2012).
This effect will vary depending on land uses
because different land uses (e.g., grazing on
grassland versus intensive cropland) do not
have the same effect on biodiversity. The effect of water use on biodiversity and human
health also will vary with the level of water
scarcity. Methods could be used to translate
the land and water use for livestock into impacts on biodiversity and human health (e.g.,
Alkemade et al. 2009; Pfister et al. 2009; de
Baan et al. 2013), whereas no comparable
methods exists to compute the impact of
freshwater fisheries.
In addition to the increased land and
water use to replace the loss of fish harvest,
there will also be losses of other nutritional
components that will not be replaceable by
production of livestock, for example, vitamin
A. Micronutrient deficiency significantly affects the lives and health of around 2 × 109
people worldwide (Tulchinsky 2010), with
26% of all children under the age of 5 being
stunted and 31% suffering from vitamin A
deficiency (FAO 2013). Fish contain several
amino acids essential for human health and a
unique lipid composition with many potential
beneficial effects for adult health and child
development and is an important source of
essential micronutrients (vitamins D, A, and
B) and minerals (calcium, phosphorus, iodine,
zinc, iron, and selenium); this is especially
true for many small fish species that are consumed (Kawarazuka and Béné 2011; HLPE
2014). Clearly, the fish consumed in the region
contribute significantly to nutritional requirements for calcium, iron, zinc, and vitamin A,
in addition to protein (Table 4), and contributes significantly to the nutrient requirement
for women (Chamnan et al. 2009). Replacing
these nutrients from fish with livestock would
require even more land and water than simply
replacing the protein.
The decisions leading to the construction
of dams on the Mekong were based on the
value of electricity and water for agriculture
and municipal use. The value of inland fishery resources and the cost of replacing them,
in terms of both land and water, were not adequately considered in our opinion. We do hope
however, that with improved knowledge on the
importance of freshwater fish, more informed
decisions can be taken in countries in the lower Mekong River basin and elsewhere.

Abstract.—Water availability is driven by external forces, including climate
change and human population growth. Inland fisheries are one of many social and
economically important sectors that utilize inland waters. Increasingly, the competition for water leads to tough decisions and trade-offs are often made between water
resource sectors. However, decisions that consider multiple sectors can lead to synergies in management approaches (i.e., win–win scenarios), which benefit multiple
sectors. Ultimately, in searching for sustainable solutions for fish, these ecologically
and socially responsible approaches can contribute to improved health, well-being,
and prosperity for all water resource sectors.
Introduction
Less than 3% of the world’s supply of water is
fresh (Stiassny 1996). Yet freshwater is home to
more than 40% of known fish species (Kummu
et al. 2011). Not surprisingly, this small fraction
of water provides a large range of economically,
culturally, and ecologically valuable services to
many important sectors. Increasingly, the competition for water leads to tough decisions, and
trade-offs are often made between these sectors.
Inland capture fisheries from lakes, rivers,
streams, canals, reservoirs, and other landlocked waters for food, income, or recreation
(FAO 2014a) is one important sector that relies
upon water of suitable quality and quantity. Inland fish provide a major source of protein, essential fats, and micronutrients for hundreds of
millions of people globally (Youn et al. 2014). In
low income countries, inland fisheries provide
livelihoods for more than 60 million people and
women represent more than half of those in
inland fisheries supply chains (FAO 2014b). Inland fish and fisheries also provide cultural and
recreational services and contributions to human health and well-being (Lynch et al. 2016).
Though inland fish and fisheries are important in providing food security, human well-being, and ecosystem productivity, inland fisheries
are often underappreciated or not considered
during water resource planning (Lynch et al.
2016). Valuation of inland fisheries is difficult
and the governance structures for water are often complex, unclear, or nonexistent, assuring
that the direct comparisons of economic values
are often not possible (see Bartley et al. 2016;
Youn et al. 2016; both this volume). Additionally, inland fisheries are an economically small
sector, and in most cases, their value will not be
the main driver of capital or resource-based decision making.
This chapter examines the sectors that
compete most directly with inland fisheries
for water resources and discusses the global
drivers that also influence water quantity and
quality (Figure 1). Using a series of case studies
(Figure 2) to illustrate real world examples of
these issues, the chapter highlights synergies in
management approaches (i.e., win–win scenarios) and provides recommendations to achieve
a sustainable future for fish, fisheries, and other
inland sectors (Table 1). Informed management
decisions that consider the potential impacts of
all sectors on inland water systems can allow
for the development of aquatic habitat rehabilitation and protection programs, environmental
flow regimes, or other management approaches
for sustainable production of ecosystem services across multiple sectors. Ecologically and
socially sustainable approaches ultimately can
contribute to improved human and environmental health, well-being, and prosperity of all
water resource sectors, including fisheries-dependent communities.
Competing Inland Water Sectors
While fishing itself is often the largest human influence on marine fisheries, inland fish and fish-

eries are dependent upon the quantity and quality of freshwater habitats, which are influenced
primarily by external factors. Many sectors
competing with inland capture fisheries (e.g.,
hydropower, transportation, agriculture, mining, oil and gas extraction, forestry, aquaculture,
tourism, and recreation) influence management and allocation decisions for inland water
systems, often to the detriment of sustainable
inland fisheries. Identifying competing sectors
should allow more informed discussions about
management of inland systems.

Concern/issue
Recommendation
Examples
Inland fisheries are not often
considered in decisions about
allocation of water partially
because they are not generally
compared in economic terms
to other sectors. In many cases,
especially in the developing
world, markets do not exist or
economic impact is not
measured for inland fish and
fisheries.
Develop market or other
other economic evaluation
approaches to communicate
the importance and the true
value (including illegal,
unreported, or unregulated)
of inland fish and fisheries
supply chain to other
sectors, particularly for
consideration in water
allocation discussions.
Development of goals around
common needs such as
production of clean water can
sometimes lead to win–win
approaches across water
resource sectors. In many
instances, however, trade-offs
between sectors and ecosystem
services from inland water
systems will be made.
Although there may be some
win–win situations,
explicitly acknowledge the
trade-offs made when
allocating water.
• The lower Mekong Delta fishery
has been assessed for its
economic as well as its biological,
cultural, and social value (Baran
et al. 2007).
• A reflooding scheme was required
to reverse impacts on fishery and
nonfishery sectors not initially
accounted for during the
construction of the Maga Dam,
Cameroon (Loth 2004).
• See Youn et al. 2016, this volume,
for further examples.
Inland fish and fisheries share
water systems with other
water resource sectors.
Planning mechanisms often do
not explicitly include inland
fish and fisheries.
Develop integrated
cross-sectoral approaches
to managing water
systems for all fishery and
and nonfishery sectors.
Inadequate communication
among sectors, stakeholders,
and partners because of a lack
of common governance
structures and differences in
objectives and language.
Use participatory approaches
to better align goals for
water management across
sectors.
• A synergy between fishery and
tourism sectors to create a new,
economically productive sector in
Guyana (see Rewa Village case
study) and aquaculture with
agriculture farming systems (FAO
2001) are examples of win–win
solutions.
• Adoption of alternative
aquaculture species and practices
as a trade-off to reduce impacts
on environmental quality (see
Mekong Delta and Wuhu Lake
case studies).
• The European Water Framework
Directive (2000/60/EC; European
Parliament 2000) and the Lake
Cyohoha community (see Lake
Cyohoha case study) require
integrated water management to
protect, among others, fish and
ecological health at the river basin
scale.
• See Bartley et al. 2016, this
volume for further examples.
• Mekong Integrated Water
Resources Management Project
integrates fishery development
along other water-use sectors
(Browder 2014) and
transboundary projects like GEO
Amazonia (UNEP 2008) foster

Recommendation
Examples
Inland fish do not appear in the
global discussion of water use.
Incorporate inland fish and
fisheries into the United
Nations Economic and
Social Council post-2015
development agenda and
other sustainability
development goals on water
issues.
• In the post-2015 development
agenda, inland fisheries are
directly relevant for at least four
sustainable development goals
(SDGs): no poverty (SDG1), no
hunger (SDG2), gender equality
(SDG5), and life on land (SDG15).

15 m are in operation globally for hydropower generation (Zarfl et al. 2014). In 2011, hydropower contributed approximately 16% of
total global electricity in more than 160 countries (Moller 2012). Brazil, Canada, China, and
the United States produce more than half of
the world’s hydropower. The World Business
Council for estimates that two-thirds of the
economic potential of hydropower remains
unexploited, mostly in the developing world,
and the International Energy Agency projects
that hydropower capacity will increase by
63% between 2002 and 2030 (WBCSD 2006).
While dams and hydropower plants are a renewable source of energy, hydropower generation can be in conflict with other water
resource users, including inland fisheries.
Nearly 50% of the world’s highest flow
rivers have been modified by dams and other
obstructions to create upstream reservoirs
(Lehner et al. 2011). The resulting habitat modifications have led nearly 65% of the world’s continental discharge (measured at the mouth of
ocean-flowing rivers) to be classified as threat-
ened (Vörösmarty et al. 2010). Dams (Note that
not all dams function for power development;
some are built to provide transportation corridors or water storage. However, the vast majority of large dams are built for power generation.)
have impacted more than half of the world’s
largest rivers, including the most biologically
diverse systems, such as the Amazon, Columbia, Mekong, Mississippi, and Nile (Nilsson et
al. 2005), with particularly negative effects on
endemic species. The construction of dams has
also resulted in long-term storage of carbon in
reservoirs and a reduction in the overall delivery of sediment to coastal zones (Syvitski et al.
2005), thereby reducing primary production
and the development of deltas and other habitat
important for inland fish production.
Progressive hydropower planning includes
biologically appropriate mitigation strategies (e.g., fish ladders, variable flow regimes)
to minimize ecological impacts on fish while
still meeting electricity demands for people. If
these factors are not taken into consideration,
dams will disrupt fish reproduction by blocking
188
lynch et al.
migration routes, both downstream and upstream, and fragmenting habitat. Reservoirs
displace many people who depend on the
natural run of rivers for their livelihoods. Replacement fisheries in reservoirs, oftentimes
aquaculture, have investment costs that often
cannot be borne by displaced fishermen. In
addition, aquaculture species may not be culturally or socially acceptable (WWAP 2014),
and aquaculture is generally unable to produce all the species that are lost. For example,
hydropower dams on the Mekong main stem
are estimated to cause losses of US$476 million per year for fisheries alone (Orr et al.
2012), and tributary dams will have strong
nonlinear trade-offs with floodplain fisheries
(Ziv et al. 2012). With committed restoration
and management efforts, such as on the Columbia River in the United States, technological mitigation may save fish stocks from local
extinction, but there is yet to be evidence that
they can provide complete mitigation for the
altered ecosystems (Williams 2008).
Inland waterways have been significantly modified over the centuries to provide
transportation corridors for commerce and
the movement of people. Modern economies
would not have been possible in the absence of
transportation on inland waters (INA 2003).
Modifications of inland waterways for transportation include the construction of locks
and dams, channelization, and alteration of
riparian corridors. Channelization increases
the potential for habitat modification. Once
modified, inland water systems often experience changes in sediment transport, water
quality, fragmentation and loss of habitat, and
shifts in hydrological regimes. Learning from
past failings, many transportation planning
efforts now include mandates to consider the
environmental consequences (e.g., environmental impact statements). For example, lock
systems developed in a side canal can accommodate continuous flow in a river system.
Additionally, extensive modification of inland water systems to affect connectivity between drainages has often created corridors
for invasive species with associated undesirable impacts (Revenga et al. 2000; Revenga
and Kura 2003). The construction of the
Welland Canal, for example, provided a commercial transportation route between Lake
Ontario and Lake Erie. The introduction and
spread of many invasive species, including
Sea Lamprey Petromyzon marinus, has been
attributed to this transportation channel (Eshenroder 2014). Commercial and recreational
fishing and tourism businesses in the Laurentian Great Lakes are believed to lose up to $50
million annually from nonnative Sea Lamprey
and mollusks brought through the creation of
these transportation corridors (Rosaen et al.
2012). Similarly, release of ballast water has
been cited as a transport vector for many invasive species (e.g., Ricciardi and MacIsaac
2000).
Water quality and quantity
Production of traditional agricultural products consistently places a large demand on
limited freshwater resources (FAO 2014c).
Agriculture produces both crops and livestock
through processes that result in impacts to
terrestrial and aquatic ecosystems. Irrigated
agriculture, alone, uses 69% of global freshwater withdrawals (Chen and Davis 2014).
With increasing food demand globally, agricultural intensification will require more
water for irrigation (FAO 2014c). During the
past 35 years, food production from agriculture has doubled, nitrogen fertilization has
increased more than sixfold, and the use of
phosphorus for fertilization has increased
more than threefold, resulting in degradation
of water quality and increases in eutrophication (Tilman 1999; see Lake Rupa case study).
Similarly, animal production facilities have
destroyed shoreline habitat (e.g., unfenced
grazing) and significantly increased nutrient
loads in local watersheds (e.g., concentrated
animal feeding operations). In that same time,
there have been collective efforts to increase
awareness and address ecological water
needs. Even voluntary adjustments to irrigation practices can have significant benefits to
fish habitat.
Agricultural impacts when unchecked,
including dewatering and eutrophication,
threaten inland fish with loss of biodiversity,
drivers and synergies in the management of inland fisheries
shifts in food webs, spread of invasive species, and large-scale changes to fisheries (Tilman 1999; see Lake Cyohoha case study). Increased nutrient loading, for example, altered
fish community composition in Ohio stream
systems, decreasing the relative abundance
of top aquatic carnivores and insectivores and
increasing the relative abundance of nutrient
tolerant and omnivorous fishes (Miltner and
Rankin 1998). More directly, fish can be diverted from rivers into irrigation canals and
even dispersed onto crops during watering
events (King and O’Connor 2007). However,
technological advances, such as fish screens,
have increasingly been implemented to address these large-scale ecological impacts
with minimal implementation costs, potentially a win–win for agriculture and the aquatic ecosystems.
As with agriculture, the costs and benefits
of mining and oil and gas extraction, however,
are often misaligned with local communities
and local ecosystems, which may bear the
brunt of unsustainable practices (O’Rourke
and Connolly 2003; see Rewa Village case
study). Mineral seepage, contaminated wastewater, and dewatering (water is often a mining agent) are among the most detrimental
impacts of mining and oil and gas extraction
(e.g., hydraulic fracking) to inland fish and
aquatic ecosystems (Younger and Wolkersforfer 2004). Mining can deoxygenate water
bodies, change their pH, and increase levels
of suspended solids, which can clog fish gills
(Ashton et al. 2001). For oil and gas extraction, spills can have the most immediate environmental impacts, but water pollution from
accidental discharge from refineries, hydrocarbons especially, can also significantly impact fish abundance and diversity (O’Rourke
and Connolly 2003), as has been documented
for sturgeon species in the Caspian Sea (Becker 2000). In addition to local impacts from the
activities, transportation of oil and gas can
result in distant impacts to inland fish if, for
example, a pipeline ruptures.
Silviculture, the management of forested
systems, can be as intensive as some agricultural practices, with similar water quality
impacts. Clear-cutting, in particular, can be
189
devastating for both terrestrial and aquatic
ecosystems. Deforestation rates are particularly high in humid forests, which account
for 54% of the net loss between the periods
of 1990–2000 and 2000–2010 (Achard et al.
2014). Global estimates of tropical deforestation range from 50,000 to 170,000 km2/year
(Tucker and Townshend 2010). Deforestation near streams can change the structure,
biomass, abundance, and functional diversity
of fish communities (e.g., Bojsen and Barriga
2002; Lorion and Kennedy 2009; Dias et al.
2010; Teresa and Casatti 2012; Tanentzap
et al. 2014). Not surprisingly, fewer insectivorous and omnivorous fishes that feed on
forest-sourced organic material (e.g., wood,
leaf litter, and terrestrial invertebrates) are
found in deforested tropical streams than
forested systems (Bojsen and Barriga 2002).
In floodplain ecosystems, ongoing research
suggests that the biomass of herbivorous fish
increases as forest cover increases, and the
converse as well, explaining the critical link
between forests and fisheries (Naiman et al.
2002; C. C. Arantes and K. O. Winemiller, paper presented at the 100th annual meeting of
the Ecological Society of America, 2015). In
addition to forest benefits to fish, fish can also
benefit forests. Helfield and Naiman (2001),
for example, found increased growth rates of
Sitka spruce near salmon spawning streams
as a result of the nutrient influx from decaying salmon.
Aquaculture is the fastest-growing food
production sector in the world and accounts
for almost 50% of fish for human consumption (FAO 2014b) and is thereby increasing its
requirement for both marine and freshwater
resources. The contribution from aquaculture is expected to reach 47% of global fishery production and 53% of fish for human
consumption by 2022 (FAO 2014b). In 2012,
inland aquaculture represented 63% of the
66.66 million metric tons of farmed food fish
produced globally (FAO 2014b). Inland aquaculture growth has outpaced that in marine
waters because inland fish species are often
easier to propagate and inland aquaculture
can be more readily adapted in developing
countries. For people in Asia, Africa, and Latin
190
lynch et al.
America, inland aquaculture can be an easily
available and important source of affordable
animal protein and employment (FAO 2014b).
Inland aquaculture can be used to create
new fisheries and, in some cases, can alleviate pressure on existing fisheries (Lorenzen
et al. 2012). However, the two sectors do not
often collaborate and can even compete for
use of limited water resources. Aquaculture
facilities, particularly conversion of inland
waters to monoculture aquaculture facilities
(e.g., in China), can also lead to environmental
degradation and introduce diseases to inland
fish (Lorenzen et al. 2012; see Wuhu Lake
case study). Further, if not properly regulated,
aquaculture facilities can create eutrophication problems, and escaped fish from these
facilities often become invaders of natural
systems (see Gondwe et al. 2011; Mekong
Delta case study). Many of these environmental impacts of intensive aquaculture can be
mitigated by judicious farm siting and operational controls. However, fish produced from
aquaculture facilities for direct consumption
often do not have the same nutritional profile
as capture fisheries (Youn et al. 2014). Finally,
capture fishers displaced by aquaculture often
lack the financial capital to convert to aquaculture as an alternative livelihood, which can
negatively impact local communities.
Recreation and tourism around inland
water ecosystems creates one of the strongest
social and political constituencies for environmental education and conservation of aquatic
resources (Kearney 2002). Nevertheless, participants can change fisheries. Recreational
anglers have a vested interest in conserving
the aquatic resources upon which they depend. Often, through the nongovernmental
groups to which they belong, anglers work
proactively to conserve and enhance these resources by supporting environmental legislation; combatting illegal, unreported, and unregulated fishing; restoring aquatic habitat;
and financing fisheries management. Recreational fishing can also have negative impacts
if anglers, for example, introduce nonnative
fishes (that might be of high interest for recreational fishing) or conduct unsustainable
practices, such as harvesting undersized fish
(Post et al. 2002). Local ownership and participation are critical to capture the conservation
benefits of recreational fishing. Those who
take up the sport in their youth and witness
firsthand how fisheries change with environmental deterioration can become the greatest
advocates for wise stewardship. Globally, a
growing and better-educated middle class is
becoming increasingly aware of the ecological
consequences of unrestrained development.
Anglers, fishing clubs, and lobbying groups
are often at the forefront of these movements.
Global Drivers Impacting
Water Systems
While inland fish and fisheries compete for
water with other economically and socially
important sectors, global drivers of change
influence how all sectors, including water sectors, interact (Figure 1). These drivers (e.g.,
economic growth, diversifying economies,
population growth, urbanization, and climate
change) have synergistic and cumulative impacts. The drivers of change are particularly
important to consider, notwithstanding that
they are often beyond the scope of fisheries
management but because they strongly influence the objectives and priorities for development and management of inland waters.
Economic growth (real gross domestic product [GDP]) is expected to increase in
2014–2015 from 3.1% in 2013, largely on account of economic recovery in the more advanced economies. Global growth is projected to increase from 3.25% in 2014 to 3.75%
in 2015 to just less than 4% in 2016 (OECD
2014a). On average, real GDP growth rates
were lower in the Organization for Economic
Co-operation and Development (OECD) countries (1.7%) than globally (3.8%) in 2002–
2011. The world economy is expected to be
four times larger in 2050 than today, which
could translate to an 80% increase in energy
use, including hydropower (OECD 2012). If
sustainable practices are not prioritized, dam
construction, loss and degradation of aquatic
habitat, water abstraction for consumption in
agriculture, industry, and households, as well
as drainage of wetlands and waste generation,
drivers and synergies in the management of inland fisheries
will all impact fish and fisheries through reduced water availability and degraded spawning and nursery grounds.
Diversifying economies are altering the
distribution of contributions from traditional
sectors (e.g., agriculture, mining, and manufacturing) to service sectors (i.e., activities
not associated with manufacture, mining, or
agriculture). Between 1990–1992 and 2008–
2010, the share of service economy in GDP
rose from 66% to 74% for the OECD countries
and from 44% to 51% for Brazil, Russia, India,
Indonesia, China, and South Africa (BRIICS).
The higher contribution of services to GDP
was due in part to a shrinking agricultural
sector, particularly in the BRIICS economies
(–8%), as well as output contraction of the
industrial sector, particularly in OECD countries (–8%). Marine and freshwater fishery
products, the most traded food commodities,
were worth almost $130 × 109 in 2012 (FAO
2014b), and the structural change implies
trade-offs between export-led growth and local food security provision. The world’s lakes
and rivers support globally important inland
fisheries. Today in Europe, North America,
and Australia, these water bodies are used
mainly for recreation. In Africa, Asia, and
Latin America, their primary value is in providing food and employment for tens of millions of people. Inland waters provide 33% of
the world’s small-scale fish catch and employ
more than 60 million people, of whom 33 million are women (UNEP 2010).
For many local economies, inland capture
fisheries are vital. Inland fisheries and aquaculture also provide jobs in ancillary services
such as processing, packaging, marketing and
distribution, provision of fish tackle, maintenance of fleets, research, and administration.
About 20% of Southeast Asia’s population is
directly dependent on fisheries for their livelihoods, and an even larger share for protein
intake (OECD 2014b). In the European Union,
fisheries located in lakes and reservoirs account for more than half of the catch of inland
fish in terms of volume, and 28% of the fishers work on lakes and reservoirs; estuaries
and rivers involve a similar percentage of fishers (33%), but they only contribute to 17% of
191
the catch by volume1 (Newman 2014). Given
the continued estimates of global economic
growth, pressure will exist to further modify
waterways at the expense of inland fisheries.
The expanding human population relies increasingly on inland fisheries to ensure
food security. Total human population has increased from 5.3 × 109 globally in 1990 to 7.2 ×
109 globally in 2013. Human population grew
globally by 17% from 2000 to 2013 or by 35%
from 1990 to 2013. By 2050, the world’s human population is expected to reach 9 × 109.
Demand for freshwater is expected to increase
by 55% (OECD 2012), and demand for food
by 60% by 2050 (Alexandratos and Bruinsma
2012). Furthermore, a larger share of this population growth is predicted to occur to a greater extent in BRIICS member countries, where
reliance on inland fish for food security and
livelihood is highest.
Urbanization has also been linked to increased competition for water and aquatic
habitat through increases in industrial-scale
farming and associated water use, as well as
water quality issues associated with urban
municipal water use. In 2014, 54% of the
world’s population resided in urban areas. In
1950, only 30% of the world’s population was
urban, but by 2050, 66% will live in or near
cities (UN 2014). By 2030, the world is projected to have 41 megacities, each with more
than 10 million inhabitants (UN 2014). With
expansion of megacities near inland waters,
urbanization will continue to fragment terresAngling is the best-documented form of recreational fishing, and it was estimated in 2003
that there were at least 25 million recreational
anglers in Europe. It was estimated that more
than 20 million went freshwater fishing (Newman 2014). In 2006, it was estimated that
spending on equipment, fees, lodging, and travel
amounted to €19 × 109 in the EU27. The European Fishing Tackle Trade Association (EFTTA)
estimated that more than €5 × 109 was spent on
tackle trade and manufacturing in Europe alone,
with about 52,000 jobs directly or indirectly
benefited by this expenditure. With the inclusion of local tackle shops EFTTA estimates that
about 99,000 jobs depend on tackle manufacturing and sales in Europe.

trial and aquatic habitats and place increasing
environmental pressure on the fish resources
as the amounts of waste and other populationinduced effects concentrate around the available water.
Climate change is already influencing
inland aquatic ecosystems and greenhouse
gas (GHG) emission projections indicate that
changes will continue (IPCC 2014). In 2010,
global energy-related GHG emissions reached
a record high of 49 × 109 metric tons (UNEP
2012), and the OECD baseline scenario projects that emissions will increase nearly four
times by 2050. These anthropogenic GHG increases will drive warming atmosphere and
ocean temperatures, reduced snow and ice,
and rising sea levels (IPCC 2014). Dramatic
changes in precipitation patterns have already been observed (Chou et al. 2013). These
changes to environmental conditions will alter
water quality and quantity and, consequently,
aquatic habitat and fish production.
Case Studies: Searching for
Sustainable Solutions
The five case studies from around the world
(Figure 2) identify the variables on which decisions are made about inland water systems, explore management trade-offs, and identify how
inland fisheries are considered in or impacted
by decisions. Ultimately, the goal of these examples is to highlight discussion of trade-offs,
identification of drivers, or integration of sectors that contributed to sustainability.
Recreational ishing for sustainable
development in Rewa Village
Deep in the heart of the central Guyana rainforest, at the confluence of the Rewa and Rupununi rivers, lies the small Amerindian village of
Rewa. Fewer than 300 people live in this tiny,
remote enclave, but the Rupununi region is
home to more than 400 species of fish, about
25% of which are found nowhere else in the
world. Foremost among these endemic species are arapaima (Arapaima spp.), the largest
scaled freshwater fish on Earth.
Until recently, multiple sectors, including
oil drilling, gold mining, diamond mining, log-
ging, agriculture, and fisheries, have degraded
aquatic habitat and threatened arapaima and
other species. The people of Rewa were dependent upon these sectors for their livelihoods.
But with support from the international donor community, Rewa invested in alternative
development strategies to support livelihoods
and conservation of their important fishery
resources. In 2005, Rewa opened an ecolodge
with a grant provided by Conservation International. The village of Rewa owns and operates
the ecolodge. Approximately 80% of the villagers are employed there, working in shifts. The
staff members are 100% Guyanese with the
exception of one guide who is a fly-fishing expert and is only present when the lodge is hosting fly-fishing tourists. The lodge is open for 6
months per year, with more than 500 visitors.
The community of Rewa capitalized on
their valuable aquatic resources to develop
a profitable recreational fishing and tourism
industry. The revenue generated from fishing trips alone covers the lodge’s operational
costs. This shift in livelihoods was a win–win
for the local economy and for aquatic conservation (Table 1). By considering both the social
and economic needs of the community, as well
as the conservation of their fishery resources,
the community was able to improve both their
economic condition and the quality of their
fishery resources.
Enhancing the resilience of Lake Cyohoha
communities to climate change
Lake Cyohoha is in a transboundary catchment located in the Bugesera region between
Burundi and Rwanda. It falls within the Kagera
subbasin of the Lake Victoria basin, which is
part of the wider Nile basin. Agriculture, mostly rain-fed, is the most important livelihood
for communities in the catchment, employing
more than 90% of the population within the
subbasin. Food insecurity is a major problem,
mainly due to the small size of farming plots,
poor agricultural practices, increasing human
populations, and land degradation. Access
to basic services such as clean water, sanitation, health services, and primary education is
very poor. A legacy of civil wars and political
drivers and synergies in the management of inland fisheries
instability contributes to cross-border migration, resulting in unplanned settlements and
further degradation of the environment. Climate change also poses a growing threat (e.g.,
floods, droughts) to development and to the
well-being of communities in the catchment
and sustainability of their fisheries resources.
In the face of these threats, the local authorities and communities understand that adaptive
actions will be necessary to enhance the resilience of the Lake Cyohoha catchment to climate
change. Using an ecosystem approach, they
are promoting integrated management of land,
water, and natural resources for climate adaptation by conducting a catchment-wide assessment for Lake Cyohoha; establishing a transboundary catchment management structure;
supporting local actions for climate resilience;
strengthening capacities of stakeholders to engage in management; documenting processes
and lessons for scaling up in Burundi, Rwanda,
and other east African countries; and enhancing catchment-wide partnerships. Through
these efforts to enhance resiliency, the Lake
Cyohoha communities have concluded that
the catchment/basin is the most appropriate
unit for management and cooperation because
communities all need water and other natural
resources for various uses (e.g., agriculture,
fisheries, energy, drinking, and washing) at
that scale. Early participation and ownership
of the processes by all stakeholders (e.g., local
authorities, communities, farmers, and fishers
associations) empowers the participants, helps
ensure buy-in, and promotes water security and
climate resilience.
Lake Cyohoha faces impacts from global
drivers, such as climate change, beyond local
control. However, the local communities have
adopted comanagement approaches to address
their most immediate needs while maximizing
their resilience to drivers beyond their ability
to manage (Table 1). Both local knowledge and
global hydroclimatic models have been useful
for linking policy to practice. Through these
synergistic strategies, they have developed integrated cross-sectoral approaches to manage
water systems for all fishery and nonfishery
sectors and promote water security and climate
resilience within the Lake Cyohoha catchment.

Restoration of Lake Rupa by cooperative
management
Lake Rupa is a small, subtropical, shallow lake
with a surface area of 100 ha situated 600 m
above sea level in central Himalaya, Nepal. It
was classified as a diminishing lake in 1999.
Land-use practices in the catchment led to
sedimentation and excessive growth of rooted aquatic vegetation in Lake Rupa. Without
strong local management institutions, the lake
condition precipitously declined. Motivated to
improve their lake and its fishery resources,
329 local families formed a lake cooperative in
2002. The cooperative’s major goal was to conserve, manage, and enhance the lake’s fisheries
to benefit the community (Table 1).
Due to the action-oriented work of the cooperative’s members, the aquatic weeds were
removed and are now under control and lake
fisheries have improved (Gurung 2007). The local communities have gained more awareness
of the importance of water, the lake, and related
resources. Additionally, the fishery has benefited economically from the cooperative’s efforts.
In 2014, cooperative membership increased to
755 families, and fish sales by the cooperative
totaled around 0.85 million Nepalese rupees
(almost $8,000) in 2014. Annually, profits have
been distributed to members of the cooperative.
The cooperative has its own savings account,
has used the funds to establish a native fish
hatchery near the lake, and has several plans for
future restoration and development projects.
The Lake Rupa fishing community recognized that their livelihoods were dependent on
factors external to their fishery. Where traditional management strategies were not available to them, they self-organized and formed a
collective. The lake cooperative has been able
to improve lake condition, lake awareness, and
fisheries productivity.
Ecosystem-remediation-based lake isheries
in Wuhu Lake
China has the largest freshwater aquaculture
industry in the world, accounting for more
than 60% of global aquaculture (FAO 2014b).
In China, almost all inland water bodies, including ponds, lakes, rivers, and reservoirs,
194
lynch et al.
are used for aquaculture. In reservoirs and
lakes, the most common aquaculture practice
is net-cage or enclosure culture. There is a
huge diversity in cage size and material used
to construct net cages, as well as the species
cultured. In some lakes and reservoirs, fertilizers are used to culture plankton to support
production of planktivorous fish such as Silver
Carp Hypophthalmichthys molitrix and Bighead
Carp H. nobilis, and this often leads to eutrophication and environmental deterioration.
Lakes, amounting to 34% of the total
freshwater surface area in China, are important resources both for fisheries and for other
uses (e.g., agriculture). Many fish species are
stocked into lakes to increase aquaculture
production. The most common species are the
Chinese carps (i.e., Silver Carp, Bighead Carp,
Grass Carp Ctenopharyngodon idella, and Black
Carp Mylopharyngodon piceus). In recent years,
a trade-off between aquaculture production
and environmental protection has been applied in some lakes, such as Wuhu Lake. Managers switched to stocking higher-valued species
such as Mandarinfish Siniperca chuatsi, Mitten Crab Eriocheir sinensis, and Yellow Catfish
Tachysurus fulvidraco from the more intensive
culture of the Common Carp Cyprinus carpio.
Through this change in management strategy, Wuhu Lake managers were able to remediate the lake ecosystem condition by reduced
aquaculture intensity, but still maintain profitability through the stocked higher-value fisheries (Table 1). In short, overall production is
lowered but overall value is elevated. Ultimately, this system seeks to balance the value of
environmental protection and economic benefit of the increasingly desirable culture-based
fisheries.
Intensive inland aquaculture production
and minimizing ecosystem impacts in the
Mekong Delta
The Mekong Delta is one of the largest wetland
systems in the world, playing an important
role in local livelihoods and socioeconomic
development. Second only to rice production,
aquaculture is a primary economic activity in
the Mekong Delta and brings major foreign
investment into Vietnam. In recent years, potential profits from the culture of catfish and
shrimp have led many fruit farms and rice
fields to convert to industrial aquaculture
farms.
During the past 10 years, about 250,000
ha of fertile land that supported rice farming
in the coastal Mekong Delta were converted to
shrimp farming. This has changed the fabric of
the local economy, significantly increased income, and improved people’s lives. But it has
also caused negative effects, including ecological changes (e.g., declines in local fish, water
pollution, saltwater intrusion) and increased
risk of disease outbreaks (e.g., early mortality
disease, white spot, or pancreatic necrosis liver
disease in cultured shrimp). Deterioration of
the environment is cited as one cause for the
disease outbreak events.
Aquaculture makes significant contributions to socioeconomic development in the Mekong Delta, but it also directly or indirectly has
negative impacts, leading to conflicts between
stakeholders. To address these issues, the Vietnamese government and many nongovernmental organizations have collaboratively issued an aquaculture master plan and provided
support for many projects to treat waste from
catfish and shrimp ponds (Nguyen 2011). The
aquaculture master plan recognizes that to
develop sustainable aquaculture, the sustainability of aquatic ecosystems should be the top
priority, and that economic benefits can result
from conserving and protecting healthy ecosystems (Table 1). As a result, healthy aquatic
ecosystems will sustain a higher quality of life
for the farmers, their families, rural labor, and
all communities involved.
The Way Forward
Even as the case studies provide specific examples of how management can create win–
win situations that benefit fisheries, other
water-resource users, and aquatic ecosystems,
there are a number of key issues that hinder
inclusion of inland fisheries in water-resource
management decisions. Indeed, the diversity
of inland fisheries within complicated waterresource management frameworks means that
drivers and synergies in the management of inland fisheries
strict, prescriptive solutions to enhance the
consideration of fish and fisheries are unlikely to be of particular value. Rather, the issues
described here are purposefully broad as are
the pathways proposed to overcoming them,
though specific examples can provide more
context (see Table 1).
Overall, the omission of inland fisheries in
discussions about water use needs to be addressed. Without being involved in discussions,
it is very likely that impacts on inland fisheries
will only be addressed post hoc and potential
synergies will not be optimized. The inland
fisheries sector is not specifically included in
the United Nations Economic and Social Council post-2015 development agenda (www.
un.org/sustainabledevelopment/sustainabledevelopment-goals/). It should be. Inland fisheries are relevant and significantly contribute
directly to at least four sustainable development goals (SDG): (1) no hunger (SDG2)—in
rural, poor regions, inland fisheries can be the
primary source of food, essential nutrients, and
livelihood (Welcomme et al. 2010); (2) no poverty (SDG1)—inland fisheries provide livelihoods for more than 60 million people, mostly
in low-income countries (FAO 2014b); (3) gender equality (SDG5)—frequently, women are
in charge of postcatch handling of fish, including selling and marketing (FAO 2014b); and (4)
life on land (SD15)—inland fish production is
linked to the health of catchment-wide aquatic
and terrestrial ecosystems and to preserve fish
production will invariably require steps to protect the environment (Dudgeon et al. 2006). It
is worth noting that inland waters do not have
a standalone goal like marine systems—life
below water (SD14). More explicit inclusion
of inland fisheries in the sustainable development agenda will set a powerful example for
its inclusions at other global, regional, and local discussions.
Environmental management has a legacy
of approaching natural resources independent
of the system and disregarding the effects on
dependent processes. In water management,
it has been common for riverine systems to be
managed for specific, and often single, purposes (e.g., the construction of dams for irrigation
or agriculture; Loth 2004). The consequences
195
of these implementation practices are not always considered, and often, a post hoc amending project is required to mitigate some of the
negative impacts on other essential processes
(Loth 2004; Ziv et al. 2012). Though there has
been a move to develop and incorporate multisectoral water-use management approaches,
these actions should continue to be encouraged and adopted from the beginning of any
water management proposals. The European
Water Framework Directive (European Parliament 2000) and the Lake Cyohoha case study
are successful multisectoral approaches to water management that include the health of fish
and fisheries.
An inclusive water management proposal
requires effective communication between
stakeholders to align water management
across their various objectives. This can be
a challenge in a multisector system, as stakeholder variation can arise from views from
different competing sectors (e.g., hydropower
versus inland fisheries) and across both physical (e.g., aquaculture farms versus migrating
fish stocks) and user scales (e.g., individual,
subsistence fishers versus multinational fishing companies). This variation often, but not
always, leads to differing objectives and also to
alternative language and terminology. Participatory approaches, such as the Lake Rupa case
study, can be used to foster stakeholder communication for an inclusive water management
program. Furthermore, future cross-sectoral
collaboration may become more the norm the
longer these relationships and communication
channels are fostered.
Once involved in water-use discussions,
inland fisheries stakeholders must use the opportunity to identify synergies with other sectors. Given the often small stature of inland
fisheries within the water sector network, it is
difficult to envisage a situation where the objectives of inland fisheries will dictate or lead
discussions. Thus, it is more likely that inland
fishery objectives will be achieved through a
cooperative, synergistic strategy and a search
for win–wins with other sectors, such as the
Rewa Village, Wuhu Lake, and Mekong Delta
case studies. If these are not possible, it will
then be prudent to work towards proposals
196
lynch et al.
minimizing losses to the inland fisheries sector. Approaches like the Institutional Analysis
and Development Framework (Ostrom 1990,
2011) can assist in providing a structure to assess policy choices for multiple users and water sectors.
The above issues can be argued to be a result of the perceived trivial economic value of
inland fisheries compared to other water sectors, making the inland fisheries sector secondary in policy discussions. Assessing inland
fisheries production is inherently a difficult
process; most inland fisheries activity is smallscale, highly dispersed, and generally unreported to governmental agencies (see Cooke
et al. 2016, this volume). However, current
estimates undervalue the total socioeconomic
contribution of inland fisheries, including cultural and biological contributions (See Youn et
al. 2016). A robust estimate of the true value
of inland fisheries will be an important tool to
both raise awareness so the sector is involved
in discussions and provide a quantitative basis
for negotiations with other sectors. While improving the quality of valuation inland fisheries is an internal challenge, and some regions
have had successes (e.g., lower Mekong Delta,
Baran et al. 2007), it is possible that solutions
can be sought externally following the example
of other sectors. Benefit–cost ratio targeting,
for example, has been used to optimize agricultural land use and conservation benefits (e.g.,
Duke et al. 2014).
With better recognition of the value of inland fisheries, inland fishery governance needs
to adjust and address the discrepancy in fishery value and the consideration given to fisheries in resource management decisions (See
Bartley et al. 2016, this volume). Currently, inland fisheries are not even included in development goals. Generally, the issue is twofold:
first, the value and contribution of inland fisheries needs to be better assessed so future decisions are grounded in factual arguments, and
second, the complexities of the cross-sectoral
water resource management landscape mean
inland fisheries are often crowded out. Instead
of trying to dictate the conversation, inland
fisheries may benefit more from identifying
potential synergistic relationships (i.e., win–
win scenarios). This may result in more ecologically and socially sustainable approaches
to water management and ultimately improve
the health, well-being, and prosperity of fisheries-dependent communities.

Rehabilitating Fishes of the Murray–Darling
Basin, Australia: Politics and People,
Successes and Failures
John D. koehn
Arthur Rylah Institute for Environmental Research
123 Brown Street, Heidelberg, Victoria 3084, Australia
Abstract.—The Murray–Darling basin (MDB) in southeastern Australia, covers
1.1 million km2, involves six partner jurisdictions with a myriad of different government agencies, and, hence, provides an excellent example of the complexities of multijurisdictional management across a range of social and political tiers. In the MDB,
fish and fisheries compete for water with agriculture, which is the traditional water
user and is driven by national economics. Murray–Darling basin rivers are now highly
regulated and generally in poor health, with native fish populations estimated to be
at only about 10% of their pre-European settlement abundances. All native commercial fisheries are now closed, and the only harvest is by a recreational fishery. The six
partner jurisdictions developed a Native Fish Strategy (NFS) to rehabilitate native fish
populations to 60% of pre-European settlement levels after 50 years of implementation by addressing priority threats through a coordinated, long-term, whole-of-fishcommunity (all native fishes) approach. As there are a wide range of stakeholders,
broad engagement was needed at a broad range of government and community levels.
The NFS funding was discontinued after 10 years, not because of its lack of successes
or project governance, but due to jurisdictional political changes and funding cuts that
resulted in a failure of the collaborative funding structure. The withdrawal of considerable funding by one jurisdiction led to collective decline in monetary contributions
and posed a threat to the multijurisdictional structures for both water and natural
resource management (NRM) within the MDB. As a consequence, there was a review
and reduction in NRM programs and a subsequent reduction in focus to the core business of water delivery. Reflection on the NFS, however, provides some useful insights
as to the successes (many) and failures (funding) of this partnership model. Overall,
the strategy and its structure was effective, as exhibited by an audit of outputs, outcomes, and networks; by the evident ongoing advocacy by NRM practitioners and the
community; and by the continuation of ideas under other funding opportunities. This
has provided a powerful legacy for future management of fishes in the MDB.

levels of flow regulation, water abstraction, and
floodplain and riparian modification (Murray–
Darling Basin Commission 2004). There have
recently been major reforms to provide more
water for the environment (The Basin Plan;
Koehn et al. 2014a; Murray–Darling Basin Authority, Basin Plan, www.mdba.gov.au/basinplan), and this remains a politically sensitive
issue (Koehn 2015). In parallel, the Native Fish
Strategy (NFS) for the Murray–Darling Basin
2003–2013 was developed to rehabilitate the
native fishes of the MDB by addressing a range
of other threats in addition to flows (Koehn
and Lintermans 2102).
The MDB covers 1.1 million km2 or 14%
of Australia’s land area and is governed by
six partner jurisdictions: four states (South
Australia, Victoria, New South Wales, and
Queensland), a territory (Australian Capital
Territory; Figure 1), and the national government. These respective governments have a
myriad of different departments and agencies
that have varied and disparate responsibilities, goals, and objectives providing considerable challenges to effective natural resource
management, especially for fish and fisheries (Koehn and Lintermans 2012). Water use
and management is coordinated across jurisdictions through the Murray–Darling Basin Authority (MDBA). The MDBA comprises
committees of ministers and departmental
representatives from jurisdictions, as well as
the Basin Community Committee, consisting
of community members from the basin’s water
users, indigenous peoples, farming, and environmental water management sectors (www.
mdba.gov.au/about-us). Most of the funding for
the MDBA comes from collective state contributions. Despite the MDBA’s coordinating role
with respect to water, most natural resource
management (NRM), including most rivers and
fish populations, is the prime responsibility of
various state departments, among which there
can often be a lack of coordination.

This paper illustrates the multijurisdictional governance of the MDB and the arrangements used to engage the wide range of stakeholders and agencies in a partnership model
for the rehabilitation of fishes. It assesses the
successes and failures of the program and
makes suggestions to address the obstacles
identified.
Native Fish Populations
Assessment of the health of rivers in the MDB
indicates that 19 of 23 river valleys are rated
to be in “poor” to “extremely poor” ecological
condition (Davies et al. 2010). Native fish populations have suffered substantial declines
and are now estimated to be at about 10% of
their pre-European settlement (mid-1800s)
levels (Murray–Darling Basin Commission
2004). All freshwater commercial fisheries
for native species have been closed with harvest now only from the recreational fishery.
Despite their diminished status, native fishes
still have important ecological, social, cultural, and economic values and provide a key
link between the community and their waterways, particularly so for Aboriginal and rural
Australians, such as within the MDB (Koehn
2015). Aboriginal people have many impor-
203
tant cultural connections to MDB fish species
(Rowland 2005; Ginns 2012). Recreational
fishing is an important pastime in Australia,
with a participation rate of almost 20% nationwide and higher in rural areas such as
the MDB (Henry and Lyle 2003). Recreational
fishing contributes significantly to tourism,
providing economic benefits to many rural areas (Ernst and Young 2011).
The Native Fish Strategy
The dire state of freshwater fish populations
provided the community and agency impetus
that resulted in the MDBA developing the NFS
to attempt to rehabilitate native fish populations (Murray–Darling Basin Commission
2004). The NFS was a commitment between
all partner jurisdictions to address existing
threats to fishes (Murray–Darling Basin Commission 2004), this being undertaken within
the existing MDB agreement and management
structures (Figure 2). The NFS has been described and evaluated in detail by Koehn and
Lintermans (2012) and Koehn et al. (2014b).
Project level governance was undertaken by a
NFS advisory panel (NFSAP) (Figure 2; Koehn
and Lintermans 2012) that consisted of a
policy and science representative from each

state together with representatives from the
MDBA and major agencies of the national government, supported by number of disciplinespecific task forces, each with clear roles and
responsibilities (Figure 3; Table 1). Each task
force included MDBA staff and an independent scientist and ensured jurisdictional representation (often NFSAP members).
One task force (Community Stakeholder
Taskforce) focused on engagement of the
community as their involvement and support
was important, and this was a significant new
component to the management of fish in Australia (Hames et al. 2014). Strong engagement
was necessary across the range of social, political, and departmental organizational tiers,
especially with communities, stakeholders,
and jurisdictional agencies. Importantly, there
was a need for this engagement to be under-
taken by advocates appropriate for the tier of
government department or agency (see Table
2). Full-time, dedicated NFS coordinators
were appointed in each state to engage with
a variety of stakeholders through a formal
communication strategy, link research and
projects to management, act as knowledge
brokers, work directly on projects, embed fish
into wider catchment management programs,
and form links between agencies and jurisdictions. Their engagement tended to be focused
towards NRM practitioners, researchers, key
interest groups, the education sector, and the
broader community. The NFS also established
and engaged the community and other stakeholders through demonstration reaches, partnership projects with the community and relevant agencies where a series of restorative
actions were applied and rigorously evaluat-

istic and necessary, there was a reluctance to
commit to long-term funding.
The vision for the NFS was to sustain
viable fish populations and communities
throughout its rivers. The overall, aspirational
goal was to rehabilitate native fish communities in the MDB back to 60% or better of their
estimated pre-European settlement levels
after 50 years of implementation. Whist this
explicitly stated goal was controversial and
caused some nervousness within departments who were reluctant to be held to such
a commitment, it was embraced by the public
as a realistic and tangible guarantee for action. This simple, commonly accepted, readily
identifiable goal became a significant driver
for the NFS and was encompassed by the slogan “Bringing Native Fish Back.”
The community and recreational fishers indicated that they clearly recognized the
need to rehabilitate native freshwater fishes
in the MDB. There was, however, a more mixed
response from agencies and departments,
depending on their core business and fear
of making long-term funding commitments.
Water policy managers also failed to recognize that fish could be a key way to illustrate

benefits of the water reforms of The Basin
Plan and improved environmental outcomes
(Koehn 2015). While engagement at the community level was well accepted and ongoing,
engagement and familiarity with the NFS at
higher departmental and political levels dissipated over time with staff turnover, organizational changes and restructures, and the need
for politically “new” programs. Beyond the
initial establishment of the NFS, the responsibility for building advocacy at higher political
levels was never fully articulated or included
in the formal engagement strategies, and thus
effort declined over time. This neglect of effort to continually engage at these higher departmental and political levels was ultimately
detrimental to the NFS (Koehn and Lintermans 2012). The development of supporting
relationships takes time, and the combined
support for the NFS from the traditionally disparate (and potentially opposing) groups of
recreational anglers, the National Irrigators
Association, and the Australian Conservation
Foundation did indicate belated success in
this area. Such support was probably needed
but realistically unattainable much earlier in
the program (Koehn et al. 2014b).
rehabilitating fishes of the murray–darling basin, australia
One significant achievement from the NFS
and its engagement with the community was
that there is greater community awareness
and recognition of the need to rehabilitate
waterways of the MDB to recover native fish
populations. The NFS did provide many “good
news” media stories that generated public interest, and a dedicated communication strategy that identified methods to inform and engage different stakeholders was valuable. The
use of champions, recognized authoritative enthusiasts, willing and able to speak to the media to promote native fish was powerful when
applied. Nevertheless, the more extensive engagement of high-profile champions may have
provided more media coverage and publicity to
the broad community, senior government officials, and politicians. Recreational fishers and
their organizations could have been engaged
earlier to provide influential political support.
The inclusion of an oral history project (e.g.,
Trueman 2011) proved useful for further community engagement.
While NFS messages were greatly enhanced by the use of Murray Cod Maccullochella peelii and other iconic fish species, this
was not so for water reform in general. Their
use as important components of river health
could have helped engender community ownership of water reforms through shared ecological objectives relating to improved fish
populations and angling opportunities (Koehn
and Todd 2012). Community support needs
to come from both local populations (usually
rural) and those more distant. While the population of the MDB is about 2 million people,
an additional 10 million people live in capital
cities and nearby population centers that also
have an interest in the MDB and its fishes, as
they either travel there as fishers or tourists
or just care that fish are there and being properly managed. This capital mass of the urban
communities was not engaged early enough
to provide the support to the strategy when it
was ultimately needed. In the years since the
defunding of the NFS, however, there has been
considerable representation at political levels
for its reinstatement.
The NFS Research and Development Program delivered approximately 100 projects
207
between 2002 and 2011 at a cost of more than
Aus$12 million (project summaries at www.
finterest.com.au) and, with them, key advances
in knowledge to assist in recovering native fish
(see Koehn et al. 2014b). The lessons learned
have not been lost due to a thorough knowledge synthesis (Barrett at al. 2013), the creation of a NFS legacy Web site (www.finterest.
com.au), and a compilation of journal papers
(Ecological Management and Restoration 15,
supplement 1), ensuring that most of the NFS
knowledge generated is available for future
programs. Demonstration reaches, where multiple interventions were practiced, were highly
successful and have continued with a variety of
regional funding initiatives. The kudos earned
by the Condamine Alliance for their demonstration reach (2012 Banksia Award for Water,
2013 Australian Riverprize, 2013 United Nations Association of Australia World Environment Day Award for Biodiversity) not only
points to success at this site, but to broader
recognition of the value of this concept. Powerful and ongoing understanding of the principles of the NFS and ongoing advocacy remains
evident among many communities and among
many NRM individuals and agencies.
Discussion
There is no doubt about the on-ground success of the coordinated approach to fish management in the MDB. While an integrated approach to water management was already
applied across jurisdictions by the MDBA, the
additional layers of community, science, and
management for fish were beneficial. Although
not unique in fisheries management, the formation of the NFSAP, supported by technical
task forces relating to particular objectives
was a new and workable model for the MDB.
Coordination of the NFS (and chairing of the
NFSAP) by an independent (nonstate) agency
also facilitated a nonpartisan, collective, consensus approach.
The success of the NFS was also principally due to the continued enthusiasm and longterm commitment of MDBA NFS staff, statebased NFS coordinators, NFSAP members, and
researchers who agreed with the NFS vision.
208

This “staying the course” built an NFS family
of committed individuals and organizations
that allowed corporate memory to build and
to be utilized in efficient delivery of projects.
Although some personnel moved into other areas, there remains a commitment by many to
attempt to continue the networks and priorities under other arrangements, although it is
recognized that in some areas this is diminishing over time. Some of the networks developed
have endured and been utilized within other
MDB programs, such as incorporating fish
and environmental flows (Koehn et al. 2014a).
The Australian Fisheries Management Forum
(chief executives of all Australian fisheries
management agencies) has also now formed
a native fish working group, and although this
has a more recreational fishery focus, it does
continue some aspects of the NFS. Many regional NRM and catchment agencies continue
components of the NFS; indeed one Catchment
Management Authority has recently launched
its own regional native fish strategy.
Ultimately, the NFS ceased after it first 10
years, not because of its lack of project successes, but due to a failure of collaborative
funding at higher political levels. This funding structure meant that the budget was susceptible to withdrawal of funding by any one
of the five state contributing jurisdictions.
Sufficient funding is always a risk to project
implementation and success, and longer-term
funding commitments are needed, beyond a
year-to-year basis, to ensure continuity. Although these are unlikely for the 50 years
envisaged for this strategy, decadal funding
would be more appropriate for such longterm rehabilitation. Mechanisms to broaden
stakeholder investment to balance against
government-only funding may have ensured
wider support and reduced risks of singleagency funding-cut decisions (see Koehn and
Lintermans 2012).
There is no doubt that the NFS improved
the way that fish are managed in the MDB. Some
of the governance structures and methods used
in this example, where the NFS endeavored to
rehabilitate native fish populations, may also be
adapted to other multijurisdictional fisheries.
Ultimately, any program can be at the whim of
overriding politics and, hence funding cuts, unless long-term agreements are securely in place.
The need to rehabilitate native fish populations
in the MDB remains, however, and the efforts
that have been made to secure the networks,
legacies, and lessons from NFS have laid the
foundations for future fish recovery actions.

Review of the Decline in Freshwater Natural
Resources and Future of Inland Fisheries and
Aquaculture: Threatened Livelihood and Food
Security in Indus Valley, Pakistan

Quaid-e-Azam Campus, Lahore 54590, Pakistan
Abstract.—Pakistan is blessed with an abundance of diverse natural resources.
The Indus River and its rich agriculture valley with five tributaries is the world’s
largest man-made irrigation network of canals. Earth-filled dams and barrages are
commonly used across an estuary to capture tidal power from tidal inflows. The
Indus River watershed also includes freshwater lakes, floodplains, and waterlogged
areas. Inland aquaculture ponds are fast emerging in the Indus River.
The sustainability and historic agricultural superiority of Indus Valley agriculture due to the use of water from the Indus River for irrigation for 5,000 years are
now under severe threat due to a rapid population explosion of 200 million people.
In addition, the Indus River is also threatened by the release of untreated industrial
and municipal effluents into the Indus River and other freshwaters, increasing salinity, waterlogging as a result of ice melting and an increase in water table, global
warming, drought, and poor management, which have led to degraded aquatic habitats and unhealthy, collapsing artisanal fisheries.
Pakistan is at high risk of food insecurity in the coming decades because of
drought and climate change. It is universally believed that climate change will impact future freshwater availability and ultimately the freshwater fish and fisheries.
This paper discusses growing food insecurity, a decline in inland fisheries, and the
ecological degradation of freshwater in the Indus River system, Pakistan.
This paper suggests alternate mitigation efforts, such as aquaculture, to compensate for the decline in freshwater capture fisheries, to address the growing
threats to livelihoods and food security of the poor inland fishing community.
Introduction
The Indus River is a vital lifeline and source of
freshwater supply in Pakistan for agriculture,
fisheries, industrial use, and human consumption. The Indus River extends from the Himalayas in the north to the Arabian Sea in the
south, with a unique range of geographical and
geological features and biodiversity, covering
mountains, plains, and deltaic environments.
The Indus River also has great global significance from an archaeological point of view as

Mohenjo-Daro is one of the oldest civilizations
along the river. Today, the river provides 80%
of all the water consumed in Pakistan. More
than 70% of the water in the Indus River comes
from the glaciers and high-altitude wetlands.
It has a total drainage area of 1,165,000 km2,
of which 712,000 km2 lies in Pakistan. Its annual flow is 207 × 109 m3, which is twice that of
the Nile River and thrice that of the Tigris and
Euphrates rivers combined. The Indus River
supplies irrigation water for about 45 million
acres (18.2 million ha) of land, which accounts
for 80% of the total arable land of the country.

Almost 180 million people are directly or indirectly dependent on the Indus River system
(Nasir and Akbar 2012).
Agriculture and irrigation are the hallmarks of the famous Indus Valley civilization
of Mohenjo-Daro (4500–2500 BC) resulting
from the freshwater natural resources of the
Indus River system, which brings freshwater
and fertile soil and silt down from the Himalayan mountain glaciers. Today, Pakistan is
one of the world’s largest producers of cotton
(fourth), wheat (seventh), rice (fourteenth),
sugarcane (fifth), chickpeas (third), milk
(fifth), onions (seventh), apricots (sixth), date
palms (fifth), mandarin oranges (sixth), and
mangos (seventh).
The Indus River originates in western Tibet
and flows northwest through mountain gorges
of northern Pakistan before entering the fertile
plains of Punjab and Sindh. Five eastern tributaries, the Beas, Sutlej, Ravi, Chenab, and Jhelum
rivers, rise in the mountains of Kashmir and
bring huge floods during monsoon rainfalls (Figure 1). The Indus Water Treaty (1960) between
India and Pakistan allocates exclusive use of the
Indus, Jhelum, and Chenab rivers to Pakistan
and exclusive use of the eastern rivers—Ravi,
Sutlej, and Beas—to India (Figure 2). Pressure
for agricultural irrigation and needs for hydropower generation grossly changed the inland
fisheries and freshwater ecology of the Indus
River and its tributaries as a result of increased
river fragmentation, construction of barrages,
dams, and irrigation canals, which had deleterious effects on fish production and small-scale
artisanal fisheries in Pakistan (Wescoat 1991).
Indus and inland isheries resources
Pakistan is blessed with vast freshwater natural resources, including the Indus River and
its rich agriculture valley of five river tributaries, the world’s largest man-made network
of irrigation canals and earth-filled dams
and barrages, freshwater lakes, floodplains,
waterlogged areas, the Indus delta, and the
fast-emerging inland aquaculture ponds. The
fisheries sector plays an important role in the
national economy of Pakistan as the industry
is worth $1.2 × 109 (Akhtar 2010). The fisheries sector contributes 1% to the country’s
gross domestic product (GDP) and 3% to the
agriculture GDP, and provides livelihood for
400,000 fishers while another 600,000 people are involved in ancillary activities (FAO
2013). Unfortunately, fishery management in
Pakistan is characterized by limited informa-

tion about fish stocks as little or no fishery
stock assessment is practiced. If such assessment is available, then it can be assumed that
before taking any decision regarding rivers,
the livelihood of the people will be considered. Dams, water locks, reservoirs, rivers,
lakes, and ponds cover an area of approximately 8 million ha possessing varying potential for development of fisheries in the Indus
Valley. However, fish catches from rivers and
reservoirs account for more than 80% of the
total inland fish production (N. Akhtar, paper
presented at the National Seminar on Strategic Planning for Fisheries and Aquaculture
to Face the Challenges of New Millennium,
2001).
The small-scale artisanal fishing communities of Indus River system use traditional
manual fishing gears and small wooden boats.
Women are engaged in household and postharvest activities. These communities are facing pressure due to the decline in river water
regime, overfishing, aquatic pollution, and
human population explosion to 200 million.
Moreover, illegal unsustainable fishing, environmental degradation, nonenforcement of
fishery regulations, and poor fish marketing
infrastructure are contributing the decline
in Indus Valley fisheries and threatening the
livelihood and food security of artisanal fishers in the Indus Valley, Pakistan. Poverty-driven overfishing by these artisanal fishers using
banned nets and practices are driven into a
vicious circle of poverty–resource degradation nexus (Khan and Khan 2011). Therefore,
a healthy, flowing Indus River and its freshwater natural resources are important for the
livelihood and food security of these riverine
communities (Irum and Hannan 2012).
The decline in the Indus Valley fisheries
and its freshwater natural resources is a result of multiple factors, including overfishing,
the decline in river flow due to climate change
and drought during the past 50 years, degradation of water quality and river environment
resulting from increasing salinity and sea
intrusion, and agricultural runoff, as well as
the impacts from infrastructure development,
urbanization, population explosion, and
other anthropogenic activities (Khan 2015).
Aquaculture may be an alternate mitigation
effort to compensate for the decline in capture fisheries to address the growing threat
to livelihood and food security of the poor
inland fishing communities. Semi-intensive

carps) and Nile Tilapia Oreochromis niloticus

fish production increased from 15,000 metric
tons in 2000 to more than 140,000 metric tons
in 2014 (Figure 3).
Indus valley and inland ishing communities
Inland fish and fisheries play an important
role in ensuring food and economic security
throughout the world. Freshwater fish are especially important in the developing world,
where it provides a critical source of animal
protein, essential micronutrients, and livelihoods for local communities. Inland fishing
communities and villages are spread along
the Indus River and its tributaries, the freshwater lakes (Manchar, Kinjar, and Haleeji
in Sindh) and man-made water reservoirs
(Tarbela, Chashma, Mangla, and Hub). These
poor fishing communities with small-scale
fisheries have suffered as natural fish stocks
in these inland freshwaters have drastically
declined during the past 5 to 6 decades due
to deforestation, overfishing, aquatic pollution, and other anthropogenic activities. As
a consequence, almost 79% of the people in
these fishing communities now live below the
poverty line (Mangrove for the Future 2010).
The traditional fishing methods were generally considered environmentally friendly as
they did not harm the ecosystem. However,
the introduction of new mechanized boats
and technologies equipped with better nylon nets with finer mesh size are becoming
harmful to the sustainability of fish stocks.
The poverty–resource degradation nexus is
further contributing to this decline in natural
resources, thereby reinforcing the poverty of
the artisanal fisher (Khan and Khan 2011).
The inland fisheries sector in Pakistan
directly supports about 100,000 people for
both food and income, and almost 1 million
people are indirectly dependent upon these
inland freshwater fisheries resources. During
the past 20 years, while the fishing fleet had
grown by 15%, the fisheries resources have
declined drastically and the fish catches have
dropped significantly (Wijeratna 2007; Khan
and Khan 2011).
Aquatic pollution is also an important
reason for the decline of fisheries in Pakistan.
The coastal habitats and the aquatic biodiversity are subject to increasing pressures arising from these anthropogenic activities.
Institutional and policy shortcomings are
also strong reasons for the decline in freshwater fisheries. Fisheries management measures appear to be confined to a few technical
management measures such as closed areas
and closed seasons. There is not a comprehensive policy plan for sustainable fisheries
development, management, conservation,
or restocking of native stocks. Enforcement

threatened livelihood and food security in indus valley, pakistan
of fisheries regulations is a neglected aspect
of fisheries management in Pakistan (Wijeratna 2007; Khan and Khan 2011). Due to the
shortage of funding, trained human resources, fisheries departments, and other enforcement agencies are ill equipped, ineffective,
and unable to implement and enforce the
fishing regulations, thereby promoting overharvesting and decline of freshwater fisheries
in Pakistan.
The lack of environmental awareness, absence of stock assessments, and nonreplenishment of the depleting fish stocks is further
complicating and aggravating the freshwater
fisheries in Pakistan. It is encouraging that society and community organizations like the International Union for Conservation of Nature, the
World Wide Fund for Nature, Fisher Folk, and
educational institutions have successfully raised
awareness to protect mangroves of the Indus
delta, now declared a Ramsar site. Similarly,
the Indus Valley community has been involved
in mangrove replantation campaigns to reduce
the release of untreated industrial effluents and
municipal wastes into the river environment.
Therefore, the very survival of freshwater fisheries lies in a change in thought process of the
communities, government and nongovernmental agencies, and other stakeholders, along with
the strong political will of the government.
215
Climate change, drought, and inland
isheries
Due to Pakistan’s arid to semiarid climate
(Figure 4), freshwater is the single most constraining factor for fisheries and aquaculture
development. Once abundant, now scarce, Indus Valley freshwater natural resources are
predominantly used for agriculture through
wasteful flood irrigation techniques. Demand for water is increasing from population
growth and industrial and agricultural development. These declining freshwater resources are further threatened by drought and
long-term impact of climate change through
its effect on temperature, precipitation, and
Himalayan glaciers runoff (Wescoat 1991; Xie
et al. 2013).
Studies suggest that to minimize the negative impacts of drought and long-term climate
change, Pakistan has to immediately take steps
like expanding reservoir storage, increasing
irrigation efficiency and water use, shifting
to drip irrigation, and adaptation of modern
water recirculation aquaculture systems for
fish production (Wescoat 1991; Ahmed 2002).
This can be achieved through development and
implementation of policies to monitor the factors discussed above for sustaining fisheries in
Pakistan.

Inland aquaculture
khan
Global production of farmed fish has more than
doubled during the past 30 years. Today, aquaculture is probably the fastest-growing foodproducing sector and accounts for almost 50%
of the world’s food fish and is perceived as having the greatest potential to meet the growing
demand for aquatic food (Bostok et al. 2010). In
recent years, aquaculture has emerged as one
of the fastest-growing and important economical agribusinesses, worldwide (FAO 2015). The
aquaculture industry, with an impressive and
unprecedented present growth rate of 10–15%
compared to agriculture, livestock, poultry, and
other food-producing sectors, has grabbed the
attention of investors, multinational companies, banks and corporate bodies, and progressive fish culturists, globally.
The global decline in capture fishery has
further highlighted the importance of fish
production from alternate sources of aquaculture. Today, aquaculture is the most suitable
agribusiness for investment due to its broad
choice of species diversity, sustainability, consistency, ever-increasing demand, potential for
better rate of return, and reduced risks compared to other farming systems like poultry
and livestock. Importantly, fish is the only cash
crop in Pakistan sold on net cash, while other
crops like wheat, rice, and other cereal grains
are traditionally sold on loan basis to creditors
(FAO 2006; Jha 2010). Therefore, aquaculture
has the potential to bring into use the saline
and waterlogged, wasted, and marginal agriculture lands, which are otherwise unfit for
agricultural crops. Pakistan can augment the
production of inland fisheries by promoting
early maturing stocks like tilapia and the introduction of protein-rich fish feeds, in addition to
traditional pond manuring and fertilization for
carp and tilapia production. Fast-growing tilapia may be a better alternate species to grow in
Indus Valley brackish waters than traditional
fish species.
fisheries and aquaculture in Pakistan, revealing that freshwater and fisheries resources in
the Indus River have declined during the past
5 to 6 decades. Therefore, the sustainability
and the historical agricultural prominence of
Indus Valley agriculture for centuries is now
under severe threat due to a rapid population
explosion of 200 million people, the release of
untreated industrial and municipal effluents
into the Indus River and other freshwaters,
increasing salinity, waterlogging, drought and
climate change, and poor water management,
leading to degraded habitat and unhealthy
subsistence and artisanal-level fisheries. Further, the historic river fragmentation due to
the Indus Water Treaty of 1960, the construction of large dams, barrages, and a huge network of irrigation canals has not only changed
the Indus River ecology, but has brought deleterious effects on fish production and smallscale, riverine, artisanal fishing communities.
In conclusion, today, the inland fisheries in
Pakistan are threatened by severe environmental degradation, improper fisheries management, indiscriminate overexploitation of
stocks, illegal fishing practices, agricultural
runoff, population explosion, and other anthropogenic activities. Perhaps aquaculture
can provide a new and innovative alternate
to declining inland fishery in Pakistan and the
paradise lost.

Abstract.—Freshwater tropical island environments support a variety of fishes
that provide cultural, economic, and ecological services for humans but receive limited scientific, conservation, and public attention. Puerto Rico is a Caribbean tropical
island that may serve as a model to illustrate the interactions between humans and
natural resources in such complex ecosystems. The native freshwater fish assemblage of Puerto Rico is distinct from mainland assemblages in that the assemblage
is not diverse, all species are diadromous, and they may be exploited at multiple life
stages (e.g., postlarva, juvenile, adult). Primary large-scale drivers of recent wateruse policy include economic growth, human population density, and urbanization,
with climate change as an overarching influence. Watershed and riparian land use,
water quality, river flow and instream physical habitat, river habitat connectivity,
exotic species, and aquatic resource exploitation are important proximate factors
affecting the ecosystem and fisheries. Research on ecological processes and components of the stream and river fish assemblages has expanded the knowledge base
in the past decade with the goal of providing critical information for guiding the
conservation and management of the lotic resource to optimize ecosystem function
and services. The greatest challenge facing Caribbean island society is developing
policies that balance the needs for human water use and associated activities with
maintaining aquatic biodiversity, ecological integrity and services, and sustainable
fisheries. Achieving this goal will require broad cooperation and sustained commitment among public officials, agency administrators, biologists, and the public toward effective resource management.

Environmental and Societal
Setting of Caribbean Island
Ecosystems
kwak et al.
Tropical islands are important ecosystems
that harbor unique and diverse terrestrial and
aquatic faunas. The marine fishes and fisheries
of tropical islands typically receive substantial
scientific, conservation, and public attention,
but island freshwater environments also support a variety of fishes that provide cultural,
economic, and ecological services for humans.
The fish assemblages in such freshwaters vary
widely in diversity, life history patterns, and
level of human interactions. The objectives of
this contribution are to describe the components of Puerto Rico inland fisheries and their
services as a Caribbean island case study, identify large-scale drivers and proximate factors
that influence water-use and fisheries policy
and management, summarize research to inform decisions, and provide conclusions and a
future outlook.
Puerto Rico is a moderately sized Caribbean tropical island that may serve as a model to illustrate interactions between humans
and natural resources in such complex communities (Figure 1). The native freshwater
fish assemblage of Puerto Rico is distinct from
mainland assemblages but typical of oceanic tropical islands in that it is not diverse,
all species are diadromous, and they are exploited at multiple life stages. Puerto Rico is
an ideal setting to study human influences on
aquatic resources because of an extremely
dense human population and the associated
demands for water and activities that impact
freshwater and marine ecosystems and fisheries (Ramírez et al. 2012). We have studied
various ecological processes and components
of the stream and river fish assemblages of
Puerto Rico during the past decade with the
goal of providing critical information for
guiding the conservation and management of
the lotic resource. Our findings may serve to
identify and elucidate aquatic ecological functions, services, and drivers of freshwater fisheries to better inform natural resource agencies in strategic planning and implementation
of such plans.
The Biota
The Caribbean regional fish fauna is notably
diverse, but the freshwater island fish assemblages are much less so. The freshwater fish
fauna of Puerto Rico includes a moderately diverse assemblage of 14 orders, 29 families, and
82 species (Kwak et al. 2007; Neal et al. 2009)
of which only 26 are obligate freshwater species. These include at least 37 predominantly
marine or estuarine fish species of 18 families
(Neal et al. 2009). Among the freshwater fish
species (Table 1), only 7–10 species are native,
representing four families (the Sirajo Goby
Sicydium plumieri has been split into four distinct Sicydium species (Watson 2000); it is not
clear which are present in Puerto Rico). These
native freshwater fishes occur throughout the
Caribbean (Froese and Pauly 2015) and are of
primary conservation and management concern at local and regional scales.
Native diadromous ishes
All of the native freshwater fishes of Puerto
Rico are diadromous and require marine–
freshwater connectivity to complete their life
cycle. Among the native freshwater fishes, only
one, American Eel, is catadromous, and the
remaining species are amphidromous (Figure
2), including gobies (Gobiidae, up to five species), sleepers (Eleotridae, three species), and
mullet (Mugilidae, one species) (Table 1; Kwak
et al. 2007; Neal et al. 2009). Amphidromy is
a unique life history in which adults live and
spawn in streams, larvae hatch and drift downstream to the sea, pelagic larvae develop and
grow in estuaries or the ocean, and postlarvae
recruit to rivers and migrate upstream (Figure 2; McDowall 1999; Keith 2003; Keith et al.
2008). Amphidromy is common among native
fish assemblages of tropical and subtropical islands of volcanic origin (Keith 2003; March et
al. 2003).
Exotic freshwater ishes
The freshwater fish fauna of Puerto Rico is
dominated by exotic fishes (Table 1). Of the
45 primarily freshwater species on the island,
38 are introduced exotic species (Kwak et al.
2007; Neal et al. 2009). In fact, the number of
drivers of caribbean freshwater ecosystems and fisheries

freshwater exotic fish species and ratio of exotic-to-native freshwater fishes in Puerto Rico
is among the highest globally for island faunas
(Erdman 1984; Vitousek et al. 1997). Exotic
fishes were introduced to Puerto Rico through
intentional stockings, escapes from the aquaculture industry, aquarium releases, and anglers. Recent introductions include the Sailfin
Catfish, Chinese Algae-eater (also known as
Siamese Algae-eater), and an expanding list of
species from the families Poeciliidae and Cichlidae (Table 1; Bunkley-Williams et al. 1994;
Kwak et al. 2007; Neal et al. 2009). Some of
these exotic fishes provide recreational fisheries and human food sources in areas where native fish cannot survive (e.g., reservoir habitat),
but the majority are invasive species that are
detrimental to native fishes and habitat (Erd-
man 1984; Fuller et al. 1999; PRDNER 2008).
Exotic species may be harmful to native fish
by direct (e.g., predation, aggressive behavior)
or indirect (e.g., habitat destruction, competition) processes and can function as vectors of
pathogens and parasites (Bunkley-Williams
and Williams 1994; Font and Tate 1994; Brasher 2003). The impact of exotic introductions to
Caribbean native species and the freshwater
ecosystem is complex, is not well understood,
and warrants additional research.
Freshwater isheries
Freshwater recreational fisheries exist in
stream, river, and reservoir environments in
Puerto Rico. Recreational and subsistence fisheries for freshwater native fishes exist for two
primary life stages—adult fish in rivers, and
drivers of caribbean freshwater ecosystems and fisheries
postlarval stages at river mouths as the postlarvae migrate upstream from marine to riverine environments. Our personal observations
confirm that fisheries for adult native fishes
can be popular in riverine environments, especially in lowland reaches, but fishing effort and
exploitation rates are largely unknown. The
target species in streams and rivers may be
variable and span both freshwater and marine
species, including Bigmouth Sleeper, Mountain
Mullet, Tarpon Megalops atlanticus, and multiple species of snook Centropomus spp. A single
survey in 2014 at the Arecibo River mouth and
estuary in northwest Puerto Rico suggested
that effort, catch, and harvest may be concentrated spatially to the freshwater–marine interface and temporally coinciding with mass
migrations of amphidromous postlarval fish
(authors’ unpublished data).
Postlarvae of native amphidromous fishes
are individually small (12–30 mm) but can
be very dense and numerous during periodic
migrations that support important artisanal
fisheries. Such fisheries exist extensively in
tropical areas of volcanic habitat in the Pacific,
Caribbean, Central America, and Indian Ocean,
but many are in decline (Bell 1999). Postlarvae
harvest rates in these locations can be substantial (up to 20,000 metric tons/year), even
though they are seasonal and follow monthly
lunar periodicity (Bell 1999; CastellanosGalindo et al. 2011; authors’ unpublished
data). Estimates of postlarval exploitation are
rare in the literature due to the local, informal,
and largely unregulated nature of the fisheries. The species supporting these fisheries are
typically assumed to be Sicydiine gobies, but in
Puerto Rico we have found that the catch may
include species of Eleotridae and the River
Goby, in addition to Sicydiine species, that are
aggregately referred to as cetí. In Puerto Rico,
the gear used for cetí fishing is small sections
of fine-mesh mosquito netting, fished actively
by 1–3 persons along sandy banks at mouths
of rivers with large basin areas.
Recreational fisheries are locally popular
in Puerto Rico reservoirs and are primarily
managed for exotic fish species by the Puerto
Rico Department of Natural and Environmental Resources (Neal et al. 2004, 2008, 2009).
225
Facilities (e.g., public shoreline access, boat
ramps) are well developed at a few large
reservoirs, and competitive angling tournaments occur on those systems. Target species
for angling are Largemouth Bass, sunfishes
Lepomis spp., Butterfly Peacock Bass, tilapias
(Oreochromis spp. and Tilapia spp.), Jaguar
Guapote, and Channel Catfish. The policy to
manage reservoir fisheries for exotic species stems from the lack of available habitat
in those systems for native fishes (Neal et al.
2004). In one reservoir (Carite, Figure 1), a
landlocked population of native Bigmouth
Sleeper supports a recreational fishery (Bacheler et al. 2004), but the species is absent from
all other reservoirs, and efforts to culture the
fish in captivity have so far been unsuccessful
(Harris et al. 2011).
Artisanal shellfish fisheries also exist in
lower river reaches and estuaries of Puerto
Rico. Hand-net fishing for Atya or Macrobrachium shrimp, the endemic freshwater Puerto Rican crab Epilobocera sinuatifrons, the invasive
Australian red claw crayfish Cherax quadricarinatus (an accidental, unauthorized introduction), or estuarine shellfish species is common.
In addition to providing a local human food
source, crustaceans in lotic and estuarine habitats can reach high densities and biomasses
and form critical components and trophic linkages of the riverine food web (Benstead et al.
2000; Kwak et al. 2007).
The Environment
Puerto Rico is about 175 × 62 km at its longest
dimensions (8,870 km2 total) and is bisected
by an east–west mountain chain (La Cordillera
Central) from which many of the island’s rivers originate (Figure 1). A prominent trait of
Puerto Rico is its high human population density. The capital city of San Juan and other major urban centers in the coastal plain support
much of the nearly 99% urban population of
approximately 3.6 million, with a corresponding density of 406 people/km2 (CIA 2014).
Aquatic ecosystems
The topography of Puerto Rico forms more
than 50 river systems that originate at moun-
kwak et al.
226
tain elevations and flow through foothills and
coastal plain regions before draining into the
Caribbean Sea or Atlantic Ocean (Figure 1).
This pattern of river network development is
ideal for the study of lotic ecological processes and human influences in a reduced spatial
scale, relative to much larger mainland river
basins. Additionally, since Puerto Rico has
already undergone intense urbanization—a
process that is underway on a global scale in
the tropics—studies of how aquatic systems
respond to anthropogenic drivers there may
serve to predict future changes in developing
nations (Ramírez et al. 2012). Puerto Rico rivers are typical of Antillean systems, with high
gradients and coarse rocky substrate materials
with a resulting flashy, flood-dominated hydrology associated with high rainfall (averaging nearly 5 m annually, Lugo et al. 2012).
The rivers of Puerto Rico are impounded
by 27 high dams (>20 m) that form large reservoirs and hundreds of smaller low-head dams,
road crossings, and other artificial instream
barriers (Figure 1; Cooney and Kwak 2013).
Thirteen of these reservoirs exceed 100 ha in
area, and many are reduced in area by sedimentation from upstream erosion (Neal et al.
2009). These variable environments are generally regulated by water-level management
for flood control and hydropower generation,
rather than seasonal rainfall, recreational use,
fisheries management, or downstream ecological flows. Two coastal lagoons are the only
natural lentic water bodies on the island, and
they are intensively impacted by human alteration and activities.
The Human Population
The people of Caribbean islands have a long
and rich history of interaction with aquatic
natural resources. Freshwater fish are valued
and prominently featured for their natural and
cultural heritage values. The earliest known Caribbean fishers were the Taíno, pre-Columbian
inhabitants of the West Indies (Lovén, 2010).
They fished the rivers using many innovative
techniques, including hook and line, spears
and arrows, nets, baskets, weirs, and hand,
including the use of natural plant poisons to
harvest freshwater fish. The Taíno were farmers, hunters, and fishers, and their survival and
culture relied on island natural resources. A
remnant of Taíno culture and its relationship
with fisheries resources remains today in local
names for native Caribbean fishes and postlarvae (e.g., cetí, Guavina, and Dajao; Table 1) that
originated in the Taíno language (De las Casas
1951).
Under Spanish rule in the 19th century,
fishing rights at productive areas near river
mouths in Puerto Rico were sold to a small
number of fishers (Wright and Folsom 2002).
After the U.S. Government assumed control of
Puerto Rico in 1898, exclusive fishing rights
were abolished, and small commercial fisheries developed (Wilcox 1903; Wright and
Folsom 2002). Commercial fishing was conducted at the river mouths by seine, cast net,
pot gears, and hook and line, and fishing up
the rivers was primarily subsistence fishing
by families.
Today, the freshwater fisheries remain an
important cultural resource and component of
the island natural heritage. This was confirmed
in a survey of Puerto Rico households that indicated that although the public’s knowledge
about specific river systems was limited, they
would be willing to pay to maintain ecological integrity of Puerto Rico rivers (GonzálezCabán and Loomis 1997). Freshwater anglers
share information via social media, and nongovernmental conservation organizations are
active in policy and management of aquatic
natural resources.
The dense human population and limited
freshwater fishery resources require effective
regulation and enforcement to avoid overexploitation, which presents a major challenge.
For decades, Puerto Rico fisheries were regulated by a law developed in 1936 (Public Law
83 of 13 May 1936; Matos-Caraballo 2009), until 1998 when legislation was enacted mandating the Puerto Rico Department of Natural and
Environmental Resources to develop contemporary fishing regulations (Public Law 278 of
29 November 1998). Freshwater fishing regulations developed by the Puerto Rico Department of Natural and Environmental Resources
limit the allowable gears, creel limits, and asso-
drivers of caribbean freshwater ecosystems and fisheries
ciated rules, and they are enforced by the Puerto Rico Natural Resources Ranger Corps. The
Puerto Rico Department of Natural and Environmental Resources also operates the Maricao Fish Hatchery to culture freshwater sport
fish (Largemouth Bass and sunfishes Lepomis
spp.) for stocking reservoirs. Currently, there
is no inland commercial fishery and plans are
being finalized to initiate a recreational fishing
license for fresh and marine waters, but none
is required at this time.
Ecosystem and Fisheries Services
and Drivers
As with most fisheries and ecosystems in developed and undeveloped nations, the ultimate
driver regulating system integrity and fisheries productivity is the human population—and
this is especially true in Puerto Rico with a
dense, urban population. The Caribbean region is a particularly densely populated area
and Puerto Rico is among the most populated
islands (United Nations 2014). The Puerto Rico
population has fluctuated around just under 4
million people for the past decade, peaking in
2009 and decreasing steadily since. With conflicting uses of natural resources, aquatic ecosystem and fisheries management is a balance
of tradeoffs between meeting needs of human
uses and maintaining the integrity of ecosystems and sustainability of fisheries.
Human water resource needs for municipal water, agriculture, power generation, and
flood control are intensive for Puerto Rico
and most island communities. Native fish and
fisheries require suitable quantities and quality of habitat to flourish and sustain fishery
services, but human activities instream and
on the watershed can degrade habitat quality
and restrict its availability. Thus, human activities that alter watershed and riparian land use,
water quality, river flow, and instream physical
habitat; fragment river habitat; introduce exotic species; and overexploit aquatic resources
are primary factors affecting the ecological integrity of freshwater systems and the ecological services that they may provide to humans
(Neal et al. 2009; Kwak and Freeman 2010;
Engman and Ramírez 2012).
227
Research to identify and elucidate ecological
inluences and drivers
Research and a strong knowledge base can
inform and guide conservation strategies and
management actions to minimize and mitigate
detrimental consequences of human activities
on aquatic ecosystems. Collaborative research
among the authors and cooperating universities and agencies has expanded the knowledge
base substantially for river ecosystems and
fisheries in Puerto Rico during the past decade
(Kwak et al. 2007, 2013).
Modeling habitat and distributional patterns.—An initial research step was to evaluate
properties of fish sampling gears and develop
a standard protocol to assess fish assemblages
(Kwak et al. 2007). We determined that a threepass removal estimator based on electrofishing
catch was the most efficient and least biased
among the models examined to estimate density and biomass for each species within the assemblage. We followed that protocol to sample
the fish assemblages at 118 sites spanning elevations up to 700 m, covering all river basins.
The catch included 28 species from 16 families
with fish density ranging up to 83,000 fish/ha
and biomass up to 622 kg/ha, and assemblage
indices identified patterns in native and exotic
fish distributions. We found that fish assemblages upstream of a high dam and the associated reservoir differed from those assemblages
without a downstream reservoir, and native
fish were tolerant to watershed and riparian
urbanization. Thus, the use of fish assemblages
alone may not serve as suitable indicators of
ecological integrity (Kwak et al. 2013). We also
developed fish condition index relationships for
native Caribbean amphidromous fish species
(Cooney and Kwak 2010). Hierarchical models to describe fish assemblage patterns from
instream habitat parameters and landscape
attributes revealed that basin-level influences
appear to structure fish assemblages more than
site- or reach-scale factors. Thereby, the fishery
resource was described and quantified, assessment indices developed and evaluated, and the
appropriate management scale was identified.
Diadromous Caribbean fishes depend on
habitat connectivity between freshwater and
228
kwak et al.
marine habitats, and dams and instream barriers block fish migrations required to complete
their life cycle and can lead to local extirpations
(Figure 3; Holmquist et al. 1998; Greathouse et
al. 2006; Cooney and Kwak 2013). In Puerto
Rico, we identified and surveyed 335 artificial
barriers that hinder fish migration to 74.5% of
the upstream habitat (Cooney and Kwak 2013).
By integrating fish surveys and the occurrence
of dam and instream barriers into distributional models, we were able to quantify specific artificial barrier characteristics that restricted
migration and occurrence to each fish species
and assemblage component (Figure 3). Barriers 4 m high extirpate nongoby native species,
and no native species occur upstream of dams
32 m high. These findings quantify the extent
of habitat loss and identify specific traits of
critical influences on ecosystem connectivity
and fish habitat availability that may be manipulated in management.
Water quality is a critical factor affecting
freshwater ecosystems and may restrict water resource use and fish distributions. The
freshwaters of Puerto Rico have received substantial sediment, chemical, and nutrient pol-
lution from a variety of sources (Hazen 1988;
Hunter and Arbona 1995; Warne et al. 2005).
We quantified occurrences and patterns of
aquatic contaminants (organic and metals) as
related to trophic relationships and watershed
land-use characteristics of Puerto Rico streams
(Buttermore 2011). Overall, the streams were
not severely polluted, with the exception of
elevated concentrations of polychlorinated
biphenyls and mercury in several fish species
from agricultural and urban streams. Contaminant concentrations were more closely
correlated with consumer lipid content than
with trophic level. Bigmouth Sleeper may be
the most suitable fish for human consumption
with low levels of organic contaminants, but
mercury accumulation was elevated in some
instances. These findings provide public health
and natural resource agencies the scientific
information required to guide ecosystem and
fisheries management and human health risk
assessment.
Amphidromy and recruitment.—All but one
of the Puerto Rico native freshwater fishes are
amphidromous (Figure 2), and their life history
and ecology are generally poorly understood
Figure 3.—Instream dams and other artificial barriers block the migration and limit the distribution of native Caribbean diadromous fish species at varying heights, forming a continuum in the fish
assemblage from native to exotic species proceeding upstream. (From Cooney and Kwak 2013).
drivers of caribbean freshwater ecosystems and fisheries
(McDowall 1988). We conducted intensive
fish-tagging studies and extensive otolith microchemistry analyses and a survey of reproductive characteristics to elucidate patterns
and dynamics in the amphidromous life history of native Puerto Rico fishes (Smith 2013;
Smith and Kwak 2014a, 2014b). Integrated results of fish tagging and otolith microchemistry
confirmed amphidromy as the predominant
life history, with some degree of plasticity. We
defined the spawning period for native amphidromous fishes from late spring through early
fall and found that fish were capable of maturation at small sizes. Life-history parameters
indicated that amphidromous fishes followed
an intermediate periodic-opportunistic lifehistory strategy, with the postlarval migration
period during the third-quarter moon phase.
These findings have identified that critical seasonal periods and habitats for management of
specific life-history functions (e.g., migration,
reproduction) indicate that amphidromous
fish assemblages are robust to adult exploitation rates ranging between low to moderate
levels, but additional data are needed to assess
sustainable levels of postlarvae exploitation,
and that they can be successfully managed by
maintaining abiotic conditions that structure
populations and communities.
Conclusions, Challenges, and
the Future
The freshwater lotic ecosystems of Puerto Rico
provide many human benefits, and water resource needs for municipal water, agriculture,
power generation, and flood control may conflict with ecological services, including fisheries. The primary large-scale drivers of recent
water-use policy in Puerto Rico are economic
growth, population density, and urbanization,
associated with a shift from crop- and pasturebased agriculture to industry since the 1950s
(Van Beusekom et al. 2014). However, climate
change is a broad-scale, growing influence on
policy and management decisions. A suite of
tradeoffs and synergies has resulted from past
water-use decisions. For example, decisions
to construct high dams and associated reservoirs for municipal water, agriculture, power
229
generation, and flood control are detrimental
to upstream and downstream ecological integrity and associated stream services, but reservoir fisheries for exotic species provide recreational and economic benefits (Greathouse et
al. 2006; Neal et al. 2008). Common ground
between government agencies and fisheries
stakeholders has proven difficult to achieve in
communications associated with policy, fishing
regulations, and management. This remains a
key obstacle to attaining sustainable water
use and fisheries policies. Identification and
consideration of these conflicts, tradeoffs, and
synergies are critical challenges in future water use planning and policy decisions.
Climate change is an overarching influence
that has impacted Puerto Rico water resources
in the past and is an important driver to be
considered in future water use planning and
policy. Precipitation and river flow are projected to decrease in all regions of the island,
exacerbating the current water management
of this limited resource (Henareh Khalyani et
al. 2016; Van Beusekom et al., in press). Total
streamflow is projected to decrease 39–88%
from historical amounts from the 1960s to the
2090s, and projected streamflow is shown to
decrease substantially below projected withdrawals at locations critical to human water
supply (Van Beusekom et al., in press). If water allocation policy continues to favor human uses over ecological needs, the impact on
stream services and fisheries will worsen.
We identified watershed and riparian land
use, water quality, river flow and instream
physical habitat, river habitat connectivity, exotic species, and aquatic resource exploitation
as proximate controlling factors of the ecosystem and fisheries. We have conducted research
to inform and guide conservation and management activities to optimize the function
of these factors within the bounds of human
needs. These new research findings provide
the knowledge base and tools that may be applied in strategic planning and management.
This knowledge base and tool set continue
to grow and are available to conservation and
management agencies and organizations. Human water use, however, is also expected to
grow in future years, and the value of main-

taining ecological integrity of aquatic ecosystems is becoming increasingly recognized and
incorporated into Caribbean water resource
planning (González-Cabán and Loomis 1997;
March et al. 2003; PRDNER 2008). Thus, the
greatest challenge facing Caribbean island
society is developing policies that effectively
balance the needs for human water use and
associated activities with maintaining aquatic
biodiversity, ecological integrity and services,
and sustainable fisheries. Achieving this goal
will require broad cooperation and sustained
commitment among public officials, agency administrators, biologists, and the public toward
effective resource management.

Improving Rural Livelihoods through Sustainable
Integrated Fish: Crop Production in Limpopo
Province, South Africa
JaCky Phosa*
Limpopo Department of Agriculture, Aquaculture Unit, Limpopo Province
Private Bag 9487, Polokwane, 0700, South Africa
Abstract.—More than 70% of Limpopo Province’s inhabitants reside in rural
areas where high rates of poverty and malnutrition prevail. The province has constructed 171 irrigation dams for water storage. These freshwater resources were
only used as water storage for irrigation instead of multipurpose uses such as fish
production, recreation, and drinking water to address socioeconomic challenges.
The objective of the study was to develop a sustainable integrated fish-crop production system to address food insecurity, create jobs, reduce poverty, and generate
income.
The study was conducted in 2012 with the rehabilitation of a deserted water
storage dam with a total surface area of 6,000 m2. The dam reservoir was divided
into four fish ponds. Fish were stocked into these ponds with the result that carp
averaged 1.2 kg, tilapia 0.5 kg, and catfish 1.5 kg after a period of 4 months
The production system yielded about 55 metric tons of fish per annum worth
US$4,396.24 and created 110 temporary and 48 permanent jobs.
Introduction
Aquaculture can become a good way to alleviate poverty in Limpopo Province as the abundant freshwater supply could be used to raise
fish. Lots of poor people in Limpopo Province
could benefit from raising fish in their irrigation waters to provide food and cheap protein. Limpopo Province has about 90% of the
population residing in rural areas, and 47.5%
are younger than 15 years old. The province
had the highest population growth of 3.9% per
annum compared to other provinces in South
Africa (De Cock et al. 2013). The people in the
rural areas of Limpopo Province live below the
poverty line with lower access to nutritious
food and basic needs.
Limpopo Province has two major tributaries, namely the Olifants and Limpopo rivers,
with a number of storage dams built for irrigation and provision of drinking water. Limpopo

has great aquaculture potential due to the
abundant water supply created by the dams.
By contrast, other provinces such as Mpumalanga, North West, and KwaZulu-Natal do not
have the same aquaculture potential, due to inadequate water supply.
Limpopo farmers have been using flood
irrigation systems since 1997 to irrigate vegetables, maize, potatoes, cotton, and wheat
crops. The water from large water bodies was
directed through cement canals to the balancing or storage dams and later directed into
the fields through furrow or flood irrigation
system. Farmers were assisted by the Limpopo Department of Agriculture and other government agencies to register as legal entities
called cooperatives to operate in a group and
share the dividends equally.
In 2000, the change to a floppy sprinkler
irrigation system led to abandonment of the
balancing dams at most of the irrigation sites
in Limpopo Province. During 2012, the Depart-
233
234
phosa
ment of Agriculture facilitated the rehabilitation of the deserted balancing dam at a cost of
US$19,400.00 in Limpopo Province. The priority for the rehabilitation of the dam was to promote aquaculture as an opportunity to address
socioeconomic challenges.
Currently, the province has abundant water resources, including 171 agricultural irrigation schemes where people grow crops and
irrigate with water from storage dams. Communities residing in these areas are poor and
concentrate more on crop production at the
subsistence farming level. Limpopo Province
still needs to address the issues of food insecurity, malnutrition, unemployment, and other
social and economic challenges (De Cock et al.
2013). An additional way to reduce poverty
and improve rural livelihoods is to encourage
optimum utilization of available water and fish
resources in a sustainable manner.
Aquaculture is a beneficial and sustainable use of water as a medium in which to rear
organisms (Rouhani and Britz 2004). Freshwater aquaculture can contribute to economic
development and food security in rural areas
of South Africa (Rouhani and Britz 2004). The
opportunity lies in the integration of aquaculture into existing agricultural development,
without an increased consumptive demand on
water (Maleri et al. 2008).
There was a need to conduct a study to
develop a sustainable integrated fish–crop
production system to address rural poverty
and unemployment in Limpopo province. The
selection of appropriate methods for any particular water body depends on local, social,
and economic conditions and priorities (FAO
2008).
Aquaculture and fisheries opportunities in
Limpopo Province could be further developed
through aquaculture innovation, including
some minor repairs and rehabilitation of the
deserted dams, which were lying fallow. These
freshwater reservoirs could be developed
for aquaculture to improve rural livelihoods
through integrated agriculture–aquaculture
production systems. This kind of improved infrastructure can support both agriculture and
aquaculture.
Study Objectives
The objective of the study was to develop a sustainable integrated fish-crop production system
for Limpopo Province that would contribute to
•
•
•
•
reducing poverty,
creating jobs,
generating income, and
reducing food insecurity.
Study Method
The total area of 6,000 m2 surrounding the dam
was surveyed and prepared for the rehabilitation of the dam for the integrated aquaculture
production system. The dam area was prepared
by excavating with earthmoving machines to
construct four earthen fish ponds of different
sizes. The aquaculture production system was
designed and developed to allow each of the
four fish production ponds to be independent,
such that each pond had its own inlet and outlet to regulate water levels. A 250-mm unplasticized polyvinylchloride pipe was used as an inlet
channel to convey water from the canal to the
ponds gravitationally. The inlet pipe was placed
2 m under the ground inside the pond wall with
a slope of 1:1,000. The tee pipes were connected
onto the main pipe into each pond to guide the
inlet pipes. Each inlet was fitted with a valve and
a 150-mm rising spindle to control water levels.
This was done in a way to reduce costs and regular maintenance of the pipes. The soil on the embankments and floor of the ponds was compacted with the application of Bentonite to stabilize
the soil to prevent any seepage that may occur.
A pump house was built near the outlet
structure of one pond, and an electric pump
was installed inside to pump water to the crop
fields for irrigation. The intention was to minimize fertilizer inputs to crop fields by using
water for fish farming and later directing the
nutrient-enriched water from ponds to crop
fields. The Department of Agriculture provided
support to farmers through government support programs to rehabilitate the dam and cover the first production costs.
The minimum capacity of the completed
pond production system was 55,000 kg for Mozambique Tilapia Oreochromis mossambicus
improving rural livelihoods through sustainable integrated fish
(also known as Tilapia mossambica), Common
Carp Cyprinus carpio, and Sharptooth Catfish
Clarias gariepinus at a stocking density of 15
fish/m2 under limited breeding space. Under
normal circumstances, fish reared in fertilized
ponds are harvested two times per annum.
This will double the stocking capacity, as well
as increase gross income. The estimated gross
income is about $2,198.12 per harvest; thus,
having two harvests per year doubles the total
annual income to an amount of $4,396.24.
Table 1 below indicates different dimensions and expected income of the developed
fish production system.
Upon completion, the fish ponds were
covered with bird netting to protect fish from
predatory birds such as cormorants, kingfishers, herons, hammerhead storks, and others
that can cause huge damage to fish stocks. A
5-m2 grid of plain wire provided proper support to the bird net.
Pond preparations
All four ponds were fertilized with agricultural
lime and fresh chicken manure on the dry bottom to assist the growth of zooplankton as natural food for the juvenile fish before the ponds
were filled and the fish stocked. Ponds were
filled with water up to the level of 30 cm and
left for a period of 7 d to increase zooplankton
abundance. After 7 d, ponds levels were topped
up to 1.2 m and left for another 7 d before the
fish were stocked. The presence of zooplankton
was checked repeatedly and regularly using microscopes prior to the stocking of fish.
Fish stocking
Polyculture was used in all four ponds of the
production system. African Catfish, Common
Carp, and Mozambique Tilapia were stocked
and mixed in all ponds at the average mass of
5 g. The Department of Agriculture supported
farmers with the first batch of fingerlings from
the government-owned hatchery. Fish were
fed manually three times a day with commercial trout feed, which contained 38% protein
for the period of 120 d after stocking. At the
time of harvesting, after a period of 120 d, fish
attained an average mass of 1,500 g for African
Catfish, 1,200 g for Common Carp, and 500 g
for Mozambique Tilapia.
Job Creation
During the rehabilitation of the dam for construction of aquaculture ponds, the contractor
employed 30 people from the local village to
assist on the project for a period of 8 months.
The employees included a community local
officer, a health safety officer, bricklayers for
building a pump-house and monk pond outlets, welders, and other people with various
skills, including pipe laying and soil leveling on
the bottom of the ponds and embankments.
Since the facility started operating, 110
temporary employees were hired annually
during intervals of 4 months to assist with fish
harvesting. More than 48 permanent employees were appointed for fish-farming-related
activities such as feeding, netting, and ponds
maintenance.
Income Generation
Apart from earning money from crops, farmers increased their income by selling fish to the
retailers and local markets. Farmers earned
an annual estimated combined income of up
to $4,396.24 from fish sales. This income was

used to pay salaries and for maintenance of the
facility. Forty-eight farmers were involved in
the day-to-day running of the project.
Results
A freshwater storage or balancing dam was rehabilitated for aquaculture production, which
diversified water use for fish and agricultural
production. Fish of various marketable sizes
were obtained and sold to the market to generate income for the farmers. The research
yielded positive results of up to 55 metric tons
of fish to the value of $4,395.14. The mean increase in income of the farmers for the first
period of three consecutive production cycles
was $131.00, $197.00, and $255.00, respectively.
More than 140 temporary and 48 permanent jobs were created for local people who
benefitted directly and indirectly from this
aquaculture production.
On the side of agriculture, farmers benefited from the nutrient-rich water coming from
the fish ponds. Farmers harvested 20 metric
tons of maize with a value of $10,000.00 and
30 metric tons wheat worth $10,500.00, as
compared to the low harvest of 15 metric tons
of maize worth $7,500.00 and 25 metric tons
wheat worth $8,750.00 harvested prior to the
use of fish pond water. Farmers saved some
money as profit and purchased fewer fertilizers for the crops.
Discussion
The communities surrounding the ponds benefitted from the project as they secured permanent and temporary jobs to sustain their
livelihoods. Previously, the local community
members were not able to receive any remuneration. During the establishment of the
ponds, however, their lives were improved because they were able to secure food and income
to afford household needs. Local people`s situation has improved in terms of food security
by having fish as part of their everyday diet. In
terms of health, fish is a highly nutritious food
with high protein content, which is important
for combatting malnutrition.
Challenges
The Limpopo Department of Agriculture had to
mobilize funding to rehabilitate the deserted
dam on behalf of the farmers as part of a poverty alleviation program. Farmers had to obtain
water rights from the Department of Water
Affairs and obtain Environmental Impact Assessment authorization from the Department
of Economic Development, Environment and
Tourism to utilize water and rehabilitate the
dam for fish farming.
Farmers had to incur costs to purchase
commercial fish feed to speed up production
within the relatively short production period.
Farmers also experienced challenges with
obligatory costs of pumping water from the
fish ponds to irrigate the fields. All the costs
incurred were covered by fish and crop sales.

Abstract.—Nepal is rich in water resources and fishing is a longstanding tradition. Capture fisheries are an important sector in Nepal and contribute approximately 0.5% to the national gross domestic product. The fish catch data of the Phewa,
Begnas, and Rupa lakes of the Pokhara Valley from 2006 and 2011 were analyzed
to determine the harvest trends of the exotic Nile Tilapia Oreochromis niloticus and
native fish. The harvest of Nile Tilapia increased and the harvest of native fish species decreased in the lakes of Pokhara Valley. Harvest from the capture fisheries has
increased in these lakes since Nile Tilapia became established. The introduction of
Nile Tilapia in these lakes was accidental. Due to an increase in Nile Tilapia catches,
the income of the Jalari community has increased, enhancing its livelihood. The native fishes of the Pokhara Valley lakes, however, are highly valued and provide a direct livelihood for the Jalari community living around the lakes. Population growth,
urbanization, tourism, agricultural intensification, illegal fishing, and the introduction of exotic fish species are the drivers that affect the capture fisheries in Phewa,
Begnas, and Rupa lakes. Regular monitoring and stock enhancement programs for
native fish species and selective harvesting of Nile Tilapia will mitigate the problem
of overpopulation of Nile Tilapia. To control further expansion of Nile Tilapia into
other natural lakes, reservoirs, and rivers of Nepal, native fish conservation policy,
laws, and protocols should be rigorously enforced. This paper discusses the drivers
of fisheries, the increasing trend of Nile Tilapia in total fish catch, and its possible effect on native fish species and the livelihood of dependent communities of the lakes
of the Pokhara Valley.
Introduction
Inland fisheries contribute about 10–12% to
annual global fisheries production (FAO 2012)
and are an important source of income and
livelihood (Welcomme et al. 2010; Suuronen
* Corresponding author: akbalhusen@yahoo.com
and Bartley 2014). Supply of fish from inland
waters is critically important for human nutrition (UNEP 2010). Fish populations in Asia
are heavily exploited (Welcomme et al. 2010).
Inland fisheries harvest could be increased by
fishery enhancement practices (Welcomme et
al. 2010; Suuronen and Bartley 2014).

Nepal is rich in water resources and fishing is a longstanding tradition (Gurung et
al. 2005). Rivers (395,000 ha), lakes (5,000
ha), reservoirs (1,500 ha), marginal swamps
and wetlands (1,100 ha), and irrigated rice
fields (398,000 ha) are the main sources of
the capture fisheries in Nepal. Capture fisheries are an important sector of fisheries in
Nepal and contribute approximately 38% of
the total fish production (49,730 metric tons)
in the country (DOFD 2011–2012). The capture fisheries contribute 0.5% to the national
gross domestic product (Gurung 2012). The
Directorate of Fisheries Development (DOFD
2007–2008) estimated that a total of about
107,000 families are involved in capture fisheries in natural waters in Nepal. The capture
fisheries involve about 427,000 active members and approximately 580,000 direct beneficiaries. About 6.6% of the economically
active population in the agriculture sector is
engaged in the capture fisheries (Wagle and
Gurung 2011). There are 24 ethnic communities whose livelihoods are dependent on fisheries in Nepal (Mishra and Upadhya 2011).
The communities involved in fishing activities
are mostly the Tharu, Majhi, Malaha, Danuwar, Kewat, Bote, Mushar, Mukhiya, Darai,
Kumal, Dangar, Jalari, Bantar, and Rai (Gurung
et al. 2005).
In the Pokhara Valley, Phewa Lake is largest (443 ha), followed by Begnas Lake (328 ha)
and Rupa Lake (135 ha). The capture fisheries
in these lakes are traditional. Jalari, a deprived
ethnic minority fishing community, has a history of nomadic life, and approximately 300
families are spread throughout the Pokhara
Valley lakes (Gurung and Bista 2003). Fishing
is the main occupation of the Jalari community around these lakes (Wagle et al. 2007). Gill
nets were introduced in the Pokhara Valley in
the 1960s to increase the daily catch for the
Jalari’s livelihood (Rajbanshi et al. 1984). The
capture fisheries of these lakes comprised
both native and exotic fish species (Gurung
2003). Nineteen, seventeen, and sixteen native fish species, as well as four exotic fish species, have been recorded from the Phewa, Begnas, and Rupa lakes, respectively (Pokharel
2000). Nile Tilapia Oreochromis niloticus were
introduced into Nepal from Thailand in 1985
for aquaculture (Shrestha 1994). Nile Tilapia
were introduced accidently in the lakes of the
Pokhara Valley and first appeared in catches
there during 2003 (Nepal 2008). The main
goals of fisheries management in the Phewa,
Begnas, and Rupa lakes are to conserve the
native fish species and improve the livelihood
of the Jalari fisher community.
Native fish diversity in Nepal includes 228
fish species (Shrestha 2012). Native fishes are
important for the livelihood, nutrition, and
welfare of the rural people. Their livelihood
may be affected by a decline in native fish
catch. To achieve sustainable use, appropriate
planning for conservation and development
of management strategies is of the utmost
importance. This paper discusses the drivers
affecting capture fishery and the increasing
trend of Nile Tilapia in total fish harvest, their
possible effect on native fish species, mitigation practices, and the effect on the livelihood
of the dependent communities of lakes Phewa,
Begnas, and Rupa in the Pokhara Valley.
Methods
Study sites
Phewa Lake is situated in the southwestern
part of the Kaski district at 28.1°N and 82.5°E,
742 m above mean sea level (Figure 1). The
watershed area of this lake is 110 km2 (Ferro
and Swar 1978). Lamichhane (2000) estimated the water surface area of this lake to
be 443 ha with a maximum depth of 23 m.
Phewa Lake is fed by two perennial streams.
This lake fluctuates between mesotrophic and
eutrophic in different seasons (Husen et al.
2009a, 2011).
Begnas Lake is the second biggest lake
(328 ha) at 28°10’26.2″N and 84°05’50.4″E,
650 m above mean sea level (Figure 1). It is fed
by a perennial stream with a catchment area
of 19 km2 and an average depth of 6.6 m (Rai
et al. 1995). This lake fluctuates between oligotrophic and mesotrophic in different seasons
(Husen et al. 2009b, 2011, 2012).
Lake Rupa (135 ha) is the third biggest lake
and its watershed is located between 28°08’N
to 28°10’N and 84°06’E to 84°07’E, at 600 m

above mean sea level (Figure 1). The lake’s total catchment area is 30 km2. The surface area,
maximum depth, and average depth of the lake
are 1.35 km2, 6 m, and 3 m, respectively. This
lake is eutrohic (Husen et al. 2011, 2013).
Data collection and statistical analysis
The daily catches (kg) of fish species were recorded from the landing sites of the Phewa, Begnas, and Rupa lakes of the Pokhara Valley. The
fish catch data for the years 2006 and 2011 were
analyzed to determine the percent contribution
of Nile Tilapia and native species in the capture
fishery from these lakes. Information about the
types of gears, fish species, and drivers of fisheries (environmental, political, social, economic,
and human induced) were gathered from Jalari
fishers through interviews with semi-structured questionnaires. The percent composition
of the catches in the year 2006 was compared
to the year 2011 to determine changes in fish
catches in these lakes.
Results
Fishing gear and ish species
The major types of fishing gears used by Jalari
fishers in the lakes of Pokhara Valley during
2006 and 2011 were gill nets, cast nets, and
fish hooks. Gill nets 350–450 m2 were the most
common fishing gear, with different mesh sizes
to capture small to large fish. The fish species
in the catch of Pokhara Valley Lakes Phewa,
Begnas, and Rupa in 2006 and 2011 are presented in Table 1. In 2011, 24 fish species were
captured; 18 were native fish and 6 were exotic
(Table 1).
Capture ishery and catch trends
Total annual fish harvest from Lakes Phewa,
Begnas, and Rupa increased from 46.7 metric tons in 2006 to 145.6 metric tons in 2011.
During this time, Nile Tilapia catch from these
lakes increased from 0.6 metric tons in 2006 to
58.1 metric tons in 2011 (Figure 2a). Contri-

butions of exotic fish species were 86.3, 76.5,
and 83.5% of the total fish catch of the Phewa,
Begnas, and Rupa lakes, respectively, in 2011.
Phewa Lake
Annual total fish harvest increased in Phewa
Lake (Figure 2b) and native fish catch de-
creased through time. The contribution of native fish to total annual fish harvest declined
by 32.8% while that of Nile Tilapia increased
by 40.1% in 2011, as compared to 2006 (Figure 3a, 3b). Annual fish yield was 52.8 kg/ha
in 2006 and increased to 137.9 kg/ha in 2011.
Likewise, Nile Tilapia contributed 1.13 kg/ha
244

to the annual fish yield of Phewa Lake in 2006
and increased to 58.2 kg/ha in 2011. There
were shifts in contribution (%) of fish species to annual catches during the study period
in Phewa Lake. Puntius spp. contributed the
highest amount (34.9%) to the total harvest of
Phewa Lake in 2006 while Nile Tilapia (42.3%)
contributed the highest in 2011.
Begnas Lake
Annual total fish harvest from capture fishery
increased in Begnas Lake (Figure 2c). Native
fish catches decreased in 2011. Nile Tilapia percent contributions to the total annual fish catch
were 65% in 2011, as compared to 2006 (Figure
3a). Annual fish yield was 28.3 kg/ha in 2006

and increased to 127.8 kg/ha in 2011. Similarly,
Nile Tilapia contribution to the annual fish yield
was 0.34 kg/ha in 2006 and increased to 84.7
kg/ha in 2011. There were shifts in contribution
(%) of fish species to annual catches in Begnas
Lake during the study period. Silver Carp contributed the most (52.2%) to the total annual
harvest from Begnas Lake in 2006 while Nile
Tilapia contributed the most (66.2%) in 2011
(Table 1).
Rupa Lake
Contributions of exotic fish species in the total
annual fish catch increased by 33% in recent
246
husen et al.
years, with Nile Tilapia increasing by 12.02%
in the year 2011 as compared to the year 2006
(Figure 3a). There were decreasing trends of
native fish species catches in Rupa Lake (Figure 3b). The annual fish yield of Rupa Lake was
109.8 kg/ha in 2006 and increased to 332 kg/
ha in 2011. Similarly, Nile Tilapia contribution
to annual fish yield was 0.08 kg/ha in 2006 and
increased to 40.23 kg/ha in 2011. There were
shifts in contribution (%) of fish species to annual catches in Rupa Lake in the year 2011 as
compared to the year 2006. Rohu contributed
most (24.81%) to total harvest from Rupa Lake
in 2006 while Bighead Carp contributed most
(34.8%) in 2011.
Stock Enhancement
Stock enhancement was carried out in the
lakes of Pokhara Valley during 2006–2011 to
increase fish production. Eighty-five to ninety
percent of stocked fingerlings in these lakes
were native fish species. The native fish species stocked were Putitor Mahseer, Rohu, Catla,
and Mrigal, and exotic fish were Silver Carp,
Bighead Carp, and Common Carp.
Fish sales and isher income
The marketing of harvested fish from the lakes
is managed by a fish entrepreneurs committee
or cooperative of respective lakes. The total estimated revenue from the sale of fish from the
capture fisheries increased from 10.45 Nepalese rupees (NR) in 2006 to NR38.97 million.
Nile Tilapia sales increased from NR0.08 million in 2006 to NR13.51 million in 2011. However, native fish of the Pokhara Valley lakes
have their own importance. The native fish
of the Pokhara Valley lakes are highly valued,
fetching a high price in the market due to their
taste and consumer priority in comparison to
exotic fish (Figure 4). Despite reduced harvest,
native fish provide high income, which directly
supports the livelihoods of the Jalari fishers in
the communities around the lakes. Small native fish species such as Puntius sp. and Barilius sp. are nutrient-rich fish, which could help

the Pokhara Valley. Tiretrack Eel has also been
used for medicinal purposes by peoples of the
Pokhara Valley.
Drivers of Fisheries
The main drivers affecting the capture fisheries in lakes Phewa, Begnas, and Rupa are
population growth, urbanization, tourism, agricultural intensification, illegal fishing, and
the introduction of exotic fish species. Due to
the intensification of agriculture, tourism, and
urbanization in the catchment area, pollution
and eutrophication increased in these lakes.
These lakes are also facing the problems of
siltation and encroachment of lake shoreline
by local people to make agricultural land. The
water quality of the lakes has changed due to
anthropogenic activity in the catchments area
of these lakes. There is also conflict of ownership among stakeholders of the Pokhara Valley
lakes.
Discussion
Shifts in species composition
We found that there were shifts in composition and contributions of fish species in the
Phewa, Begnas, and Rupa lakes. In comparison
to Pokharel (2000), two new exotic fish (Nile
Tilapia and Sharptooth Catfish Clarias gariepinus) were recorded from the Pokhara Valley
lakes. In addition, we found fish species from
each lake that were collected early in the study
that were not collected in 2011. According to
Jalari fishers, the presence of Faketa, Chuche,
and Dunge Bam, Junge, and Rewa are still in
the Pokhara Valley lakes, but Katle and Kande
are now totally absent in the Begnas and Rupa
lakes. The present findings revealed that the
native fish contribution declined and Nile Tilapia increased in the catches from these lakes.
Such changes may be due to the following drivers: population growth, urbanization, tourism,
agricultural intensification, illegal fishing, and
the introduction of exotic fish species in lakes
Phewa, Begnas, and Rupa. The present findings
indicate that the status of these native and exotic species should be monitored intensively.
247
The findings from catch data analyses in these
lakes are alarming and stress the need for the
conservation of native fish species.
Nile Tilapia and possible impacts
Nile Tilapia were introduced accidently in the
lakes of the Pokhara Valley and first appeared
in catches during 2003 (Nepal 2008). We found
that there were noticeable increasing harvests
of Nile Tilapia. The probable reasons for the
successes of the Nile Tilapia are due to its wide
degree of environmental tolerance, diverse
diet, long life span, high variability in life history traits in response to environmental conditions, flexibility, peculiar reproductive characteristics, and aggressive behavior towards
other fish (Njiru et al. 2004, 2008; Peterson et
al. 2004; Grammer et al. 2012; Ishikawa et al.
2013). Nile Tilapia has caused a change in the
dynamics of the fisheries of the Ganga River
(Singh et al. 2014). Therefore, the effects of
Nile Tilapia and other exotic species on native
fish species should be monitored regularly and
managed properly in the lakes of the Pokhara
Valley.
Livelihood and Nile Tilapia management
Nile Tilapia increased the income of the Jalari
fishers in the Pokhara Valley in recent years. It
is due to an increase in total fish harvest from
these lakes, with major contributions by Nile
Tilapia. This study showed that Nile Tilapia
alone provided revenue of NR13.51million in
the year 2011 to the Jalari communities. The
livelihood of the Jalari fishers in the Pokhara
Valley was enhanced by the capture fisheries
with a rise in income and other indicators of
well-being (Wagle et al. 2012).
The populations of Nile Tilapia must be
balanced in these lakes for a sustainable yield
and to decrease negative impacts on native fish
species. To mitigate the increasing trends of
Nile Tilapia, a stock enhancement program of
native fish species and targeted fishing of Nile
Tilapia should be carried out on regular basis
in the lakes of Pokhara Valley. Putitor Mahseer
is a natural control for overrecruitment of tilapia (Shrestha et al. 2011). One way to mitigate the impact of Nile Tilapia is to increase the
248
husen et al.
population of Sahar by stock enhancement in
the lakes of the Pokhara Valley. Well-planned
and carefully considered stocking programs
can enhance the productivity of waters, as well
as improve the quality and profitability of fishing (Suuronen and Bartley 2014).
Future strategy for Nile Tilapia
managements
There are no known methods to completely
eradicate Nile Tilapia from natural water once
introduced (Stauffer et al. 1988; McCrary et al.
2007). Invasions of Nile Tilapia in lakes, rivers, floodplains, and wetlands are especially
problematic because they are difficult to manage. The recommendation to use totally closed
aquaculture systems and a strict ban on tilapia cultivation and transportation in natural
watersheds by McCrary et al. (2007) is very
practical and would be applicable to Nepal. To
avoid further spread of tilapia, it is necessary
to regulate aquaculture activities and fisheries
management and to develop policies to screen
invasive species before introduction into new
areas (Esselman et al. 2013). The best form of
management for Nile Tilapia in Nepal will be
prevention from introduction to new natural
resources such as lakes, reservoirs, and rivers.
Fish diversity and conservation is one of the
neglected areas of research and development
in the fisheries sector in Nepal. For conservation of the aquatic life, the Aquatic Life Conservation Act of 1961 was promulgated. However,
due to insufficient enforcement, the rules and
regulations set out in this act are hardly followed (Gurung 2003). It is difficult to manage
the aquatic resources in developing countries
due to lack of baseline data and limited investment in research and monitoring (Pringle et
al. 2000). To ensure native fish conservation,
significant improvement in law enforcement
with a high level of understanding is essential
(Gurung 2012).
Conclusions
Continuous and regular monitoring of the biological and population parameters of fish in the
lakes of the Pokhara Valley is essential to provide accurate, updated information relevant
to fisheries management. Regular monitoring
of water quality and fish catches data should
be continued. The population of Nile Tilapia
should be regulated by stock enhancement
programs for native fish species and using selective gear for tilapia population control in the
Phewa, Begnas, and Rupa lakes. Biosecurity
could be one of the strategies for controlling invasive species spread into other natural lakes,
reservoirs, and rivers, in order to protect the
native fish species in Nepal. Public awareness
is also needed to reduce further expansion of
Nile Tilapia and other exotic fish in natural waters. The impact of Nile Tilapia on native fish
could not be verified by the catch landing data
only. Further scientific study is needed to verify the impact of Nile Tilapia in the lakes of the
Pokhara Valley.

Abstract.—Governance of fish, fisheries, and freshwater resources encompasses both ecological and human well-being. Nevertheless, achieving both is challenging because of the diverse sectors competing for finite resources. This challenge is
not related to a lack of understanding of what contributes to effective governance,
but rather is due to the tendency to divide freshwater resource users into sectors
that do not coordinate their use of freshwater. A panel of experts identified six issues and recommendations for improving governance of inland fisheries. These issues are (1) the lack of cross-sectoral integration in the development and management agendas for freshwater ecosystems, (2) the need for governance mechanisms
on shared water bodies, (3) the recognition of the rights and wishes of indigenous
people and other stakeholders dependent on inland fisheries, (4) recognizing the
important role of aquaculture and how to incorporate aquaculture into governance
mechanisms, (5) how to improve fishery management, and (6) how to improve communication among institutions and stakeholders.
To facilitate addressing these six issues, this paper systematically explores how
governance of inland freshwater resources, and specifically freshwater fisheries, can
be made more effective by focusing on the following:
1. Guiding principles of governance—the values and ideals that guide the process of
governing;
2. Governing institutions—those that are charged with overseeing and controlling
effective governance of fisheries and freshwater resources
the governance processes by which problems are solved and opportunities created; and
3. Opportunities and solutions—the manner, method, and system by which the fishery sector is governed, including the policies and management actions that are
the tasks of fishery managers and policymakers for the fishery sector, and the
need for more integration between all sectors using freshwater.
Introduction
It is becoming critical that a more effective
approach for governing freshwater is implemented that comprehensively addresses competing demands from different sectors using
freshwater. Currently, about 9% of the globally
accessible freshwater is withdrawn annually
for human uses (Comprehensive Assessment
of Water Management in Agriculture 2007). A
large quantity (70%) of this water is diverted
for agricultural use, with industrial (20%) and
domestic uses (10%) being the next two largest consumers (Comprehensive Assessment of
Water Management in Agriculture 2007). The
freshwater used by these nonfisheries sectors
ultimately reduces the quantity and quality of
freshwater available for inland fish production,
including both aquaculture and capture fisheries. The demand for freshwater will continue to
rise with growing human population, further
increasing conflict related to the use of freshwater. J. Bruinsma (paper presented at the FAO
Expert Meeting on How to Feed the World in
2050, 2009, cited in FAO 2014a) estimated that
water withdrawals will double by 2050, mainly
to satisfy the increase in demand for agricultural food production.
Effective governance of freshwater is an
important component of achieving efficacy of
policies, and management activities. It is important to recognize the external influences
acting on the freshwater ecosystem and fish.
Fishery governance can no longer operate in
isolation from other sectors using freshwater.
Policymakers, fishery managers, and fishers
need to increase their understanding of and
engagement with other sectors that can impact freshwater ecosystems and, thus, the livelihoods and well-being of those in the fishery
sector.
A panel of experts who attended the global
conference on inland fisheries identified six is-
253
sues and recommendations for improving governance of inland fisheries. These issues are

The lack of cross-sectoral integration in
the development and management agendas for freshwater ecosystems;
The need for governance mechanisms on

dependent on inland fisheries;
Recognizing the important role of aquaculture and how to incorporate aquaculture
into governance mechanisms;
How to improve fishery management; and
How to improve communication among
institutions and stakeholders.
To facilitate addressing these six issues,
this paper systematically explores how governance of inland freshwater resources, and
specifically freshwater fisheries, can be made
more effective by focusing on the following:
•
•
•
Guiding principles of governance—the
values and ideals that guide the process of

Governing institutions—those that are
charged with overseeing and controlling
the governance processes by which problems are solved and opportunities created;
and
Opportunities and solutions—the manner, method, and system by which the fishery sector is governed, including the policy
and management actions that are the tasks
of policymakers and fishery managers.
What Is Governance?
Governance is a broad term used to describe
the institutions and instruments that guide
the decision-making processes used in policy
and management (FAO 2014d). Governance
254
bartley et al.
occurs at the local, national, regional, and international levels. Various definitions of governance exist. For the purpose of this review, the
following aspects, drawn from three accepted
definitions, are used:
Governance is the whole of public as
well as private interactions that [can be]
initiated to solve societal problems and
to create social opportunities (Bavinck
et al. 2005; Kooiman et al. 2005);
It includes the formulation and application of principles guiding those interactions and care for institutions that enable them. (Kooiman et al. 2005);
Governance [is] a systemic concept relating to the exercise of economic, political, and administrative authority. It
encompasses: (i) the guiding principles
and goals of the sector, both conceptual and operational; (ii) the ways and
means of organisation and coordination
of the action; (iii) the infrastructure of
socio-political, economic, and legal instruments; (iv) the nature and modus
operandi of the processes; and (v) the
policies, plans, and measures (Garcia
2009).
Governance is usually considered the responsibility of governments. However, as indicated by the above definitions, civil society
organizations (i.e., the organizations such as
nongovernmental organizations that promote
the principles of society) and private industry
must also share the responsibility for governance. How this responsibility is shared can
vary depending on the situation, with different
levels of participation, accountability, and transparency (Béné and Neiland 2006) leading to differing outcomes for resource sustainability.
Effective Governance of Inland
Freshwaters to Promote Human
and Ecosystem Well-Being
The governance of freshwater resources is
challenging because of various sectoral activities relying on freshwater (e.g., Palmer et al.
2012; FAO 2014b; Box 1). Moreover, governance in the developing world is further com-
plicated due to the dispersed nature of the inland fisheries (e.g., lack of formal landing sites,
numerous small-scale fishers, and seasonal
fishing).
A coordinated approach among the many
jurisdictions and sectoral interests that are
involved in allocating freshwater resources is
necessary (Table 1, Issue: Cross-sectoral integration is lacking in development agendas for
freshwater ecosystems; Issue: Improved governance, especially for shared water bodies is
needed). Unfortunately, there is a tendency for
policymakers to divide water-resource users
into sectors and segregate governance based
on sector and stakeholder interests (Table 2;
Committee on Fisheries 1999). The larger the
freshwater resource, the more problematic is
this segregation. There are efforts to coordinate the sectors, such as the Mekong River and
Laurentian Great Lakes (Boxes 2 and 3).
However, the coordination has not always
been successful. Governance processes for
these large freshwater systems and their fisheries can be intensely influenced, not only by
interests and demands from multiple stakeholders at different geographic scales, but
also by environmental drivers and stressors
that interact and influence fisheries abundances within the lakes and rivers. Numerous initiatives by international organizations
have attempted to promote effective governance, but they have not had much success in
fully integrating the links among water, land,
agriculture, fisheries, and food security (FAO
2014c).
Governance processes intrinsically link
ecosystem well-being and human well-being
(MA 2005; Lynch et al. 2011). Many of the ecological services provided by freshwater ecosystems contribute to human well-being. Freshwater ecosystems include lakes, rivers, and
wetlands, as well as groundwater flows and
aquifers that affect the quantity and quality of
surface waters (e.g., groundwater upwelling
that keep streams cool for coldwater fish species). Freshwater resources provide the basis
for commercial, recreational, and subsistence
fisheries; agriculture, municipal, and industrial uses; transportation; electricity generation; recreational activities; and scenic values

Box 1. Governance Reform: The Formation of the Lake Victoria
Fisheries Organization
Paul onyanGo
Governance of Lake Victoria aquatic resources required a collaborative lake-wide authority to regulate and collect scientifically reliable fisheries statistics that could be used
in its sustainable resource management. Several attempts to establish such an authority
were made, with organizations being established, failing, and being replaced by another
organization, which failed. Some of the failures were likely due to inadequate funding and
capacity, and the lack of stakeholder involvement in their design and implementation.
An example of this was the development of the Lake Victoria Fisheries Services, which
was implemented by colonial government officials who, without stakeholder involvement, made all resource management and allocation decisions. The need for regional
collaboration, however, persisted among the three riparian countries that surrounded
Lake Victoria. Thus, between 1980 and 1995, Kenya, Tanzania, and Uganda established a
subcommittee that focused on Lake Victoria fisheries as part of the Food and Agriculture
Organization of the United Nations’ Committee on Inland Fisheries of Africa in order to
provide a forum for the development and management of the Lake Victoria fish and its
fisheries. The subcommittee eventually led to the signing of the 1994 Convention for the
Establishment of the Lake Victoria Fisheries Organization (LFVO), which entered into
force on May 24, 1996 (LFVO 2001a).
The LFVO aims to foster cooperation among the three nations that have governance
rights to Lake Victoria to harmonize the national measures of each for the sustainable
development of the lake through the joint development and adoption of sustainable fisheries conservation and management measures (LVFO 1999; see Box Figure 1.1 below).
For this governance system to work effectively, all those who had a stake (influence) in
the fisheries were brought into the new governance arrangement, as mangers realized
that Lake Victoria’s fisheries could not be managed exclusively by the riparian governments and in isolation from other activities that would affect the ecology of the lake and
its fisheries, such as agriculture and mining. Additionally, the LVFO has a clear communication system and transparent decision-making process that takes a multidisciplinary
and cross-sectoral approach to the management of the fishery (LVFO 2001b). It has not
been easy to build such a governance structure, but the riparian countries have been
driven by the fact that the lake and its resources are important economic factors that can
accelerate growth in this region and, if not taken care of properly, could destroy their
economic base and societal well-being.
Box continues
(Aylward et al. 2005). Inland waters and their
fisheries are increasingly being recognized for
their role in ensuring food security, supporting
livelihoods, and enhancing well-being of local and regional human communities (Berkes
et al. 2001; FAO 2005). When freshwater ecosystems deteriorate, the fish and the human
populations that rely on them for food and
livelihoods also suffer (Committee on Fisheries 1999; Dobiez and Hecky 2011).
Holistic governance approaches that
include all freshwater users would aid in

gistic interactions can encourage cooperation
among stakeholders, as all parties can benefit
from collaboration and coordination, resulting in more sustainable freshwater resources.
Addressing conflicting interactions and the
impacts of one sector’s actions on others are
the most challenging issues for achieving coordination and collaboration. Nevertheless,
the consideration of these challenges in the
governance process and informed trade-offs
(i.e. opportunities for intelligent compromise)
may avert unintentional creation of additional social, economic, and ecological problems.
The need for holistic governance approaches
is also being voiced by other natural resources sectors including agriculture (Charlotte et
al. 2014) and land tenure (FAO 2012a; Box
4). Recommendations about how to improve
interactions among freshwater users include
cross-sectoral integration, recognition of sectoral allies such as aquaculture, and improved
communications among stakeholders (Table
1).
Governing Institutions
Endeavors to manage natural freshwater resources have taken many approaches and have
developed governance institutions focused at
different scales from the local to the international. These institutions are often focused on
specific sectors and rarely address cross-sectoral issues or evaluate the total impact of all
resource use. In some countries, this situation
is exacerbated when specific agencies and human resources addressing fisheries management are lacking (Claudio Baigún, Wetland
International and CONICET, Buenos Aires, personal communication; Table 1). While there is
a need to strengthen and integrate governance
across sectors relying on a shared freshwater
resource (Committee on Fisheries 1999; FAO
2009), there is also the need to improve management within the fishery sector (Table 1).
Although the need for international agreements, institutions, and cooperation in governance has been realized for marine fisheries,
effective governance of fisheries and freshwater resources
Table 1.—Issues and recommendations for improved governance of inland fisheries.
257
ISSUE: Cross-sectoral integration is lacking in development agendas for freshwater ecosystems.
Recommendations:
•
Promote cross-sectoral discussions about the trade-offs and synergies of inland water development
and management options that consider the inland fishery sector a partner in resource development in
an equitable manner.
•
Identify and strengthen platforms and legal frameworks for multistakeholder-based decision making
and management.
•
Incorporate inland fish and fisheries into the post-2015 sustainability development goals on water issues and include all ecosystem services provided by inland aquatic ecosystems.
ISSUE: Improved governance, especially for shared water bodies, is needed.
Recommendations:
•
Establish governance institutions (e.g., river or lake basin authorities) or expand and strengthen the
mandate and capacity of existing institutions to address inland fisheries needs in the decision-making
processes.
•
Commit to incorporating internationally agreed decisions on shared water bodies within national government policies.
ISSUE: Equity and rights of stakeholders must be respected.
Recommendations:
•
Apply the principles of the Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries in inland fisheries and, in so doing, recognize, respect, and support governance rooted in traditional customs, rights, and traditional ecological knowledge.
•
Protect the cultural heritage of indigenous people and their connections to the environment.
•
Ratify and implement the Indigenous and Tribal Peoples Convention of 1989 (No. 169), as well as the
Universal Declaration of Indigenous Peoples and other International human rights instruments.
ISSUE: Aquaculture should be an important ally.
Recommendations:
•
Adopt an ecosystem approach to fisheries and aquaculture management.
•
Recognize the common need for healthy and productive aquatic ecosystems and promote synergies
and manage trade-offs among fisheries, stock enhancement, and aquaculture.
•
Regulate and manage the use of nonnative species in aquaculture development.
ISSUE: Fishery management is necessary.
Recommendations:
•
Implement an ecosystem approach to management of inland fisheries.
•
Support effective governmental, communal/cooperative, or rights-based governance arrangements
and improve compliance with fishery management regulations.
•
Modify or establish fishery and resource management arrangements to protect the productive capacity
of inland waters and the livelihoods of communities dependent on the resource.
•
Where reduced fishing capacity is called for, establish appropriate social safeguards and provision of
alternative livelihoods for people leaving the fishery sector.
ISSUE: Improved communication among users of freshwater is essential.
Recommendations:
•
Building from the small-scale fisheries guidelines and other relevant instruments, use appropriate
and accessible communication channels to disseminate information about inland fish, fishers, and fisheries to raise awareness about inland fisheries’ values and issues, to alter human behavior, and to influence relevant policy and management.
•
The fisheries sector should engage other users of freshwater resources and participate in national and
international fora that address freshwater resource issues, conflicts and synergies.
•
The fisheries sector should invite other users of freshwaters to participate in fisheries management
fora.

the recognition is only slowly emerging that a
similar system of governance is necessary at a
basin scale in transboundary and international
inland waters, where fish stocks and water resources are shared (Beard et al. 2011; Table
1). International mechanisms can offer guidance and support for the resource governance
that addresses human and ecosystem wellbeing. For example, the Mekong River Commission (Box 2) was established to provide
advice about shared resources of one of the
world’s most important rivers for inland fisheries (Hortle 2009; Mekong River Commission
2014; Barlow 2016, this volume). Resolution
IX.4 of the Ramsar Convention (Ramsar 2005),
which addresses the conservation, production,
and sustainable use of fisheries resources,
stresses, inter alia, that “local, national, and international mechanisms should be established,
as appropriate, whereby allocation of essential
resources for the protection of aquatic resources and specifically fisheries resources are
negotiated among all users of the resource.”
The European Water Framework Directive (EU
2014) emphasizes the river basin approach
for the integrated and coordinated river basin
development and management of all European
river systems. The framework calls for a comprehensive ecological assessment and classification on the basis of the composition and
abundance of the aquatic fauna and flora and
taking into account the type-specific reference
conditions of the water body.
Currently, numerous regional frameworks,
commissions, and lake or river basin authorities
provide advice about, or deal directly with, the
management of inland waters and living aquatic
resources (FAO 2007). However, only 44% of
the international basins reviewed are subject to
one or more agreements (Table 3); these agreements generally address a variety of issues that
may or may not include fisheries. Most of these
agreements do not consider ecosystem well-being or fisheries and instead are focused on water as a resource to be managed for irrigation,
flood protection, navigation, or hydropower
generation (FAO 2007). A more recent review
in Latin America revealed that among the 50
international water bodies assessed, fewer than
50% had agreements or mechanisms to address fishery and resource governance issues
(COPESCAALC 2011). The Food and Agriculture
Organization of the United Nations (FAO) maintains regional fishery bodies that address inland
fisheries and aquaculture (FAO regional fishery
bodies, www.fao.org/fishery/rfb/search/en).
However, unlike many marine groups that have
management authority and similar to the Mekong River Commission example above, the FAO
inland fishery bodies are purely advisory.
At the national level, it is recognized that,
often, institutions are not set up to implement
effective governance of fisheries and freshwater resources
259
Box 2. Dams on the Mekong and the Mekong River Commission
Chris BarloW
Governance of the Mekong water resource is divided into the upper (China and Myanmar) and lower reaches (Cambodia, Laos, Thailand, and Vietnam). Balancing national
and regional interests is problematic with history showing that national interests generally take precedence over more local interests (Osborne 2009). Policy decisions are often
not based on scientific evidence, but rather can be influenced by personal ideology and
opportunism. The decentralization of government is a policy in Laos, which has allowed
provincial governors to make decisions about the exploitation of natural resources, with
implications generally stretching far beyond their provinces. More formally, the 1995
Mekong Agreement signed by the four lower Mekong countries, aims to jointly manage
the shared freshwater resources and sustainably develop the river through the Mekong
River Commission (MRC); see www.mrcmekong.org ). The MRC’s mandate is advisory,
with the power to implement the MRC’s recommendations resting with the four national
governments, limiting the effectiveness of the MRC in influencing the management of
the Mekong River. Complaints about the perceived ineffectiveness of the MRC to sustainably and equitably manage the resources of the Mekong River may have credence, but
the basis for the argument lies more with the governance structure than with technical
performance.
Six lessons can be drawn from the experience to date with development of dams on
the mainstream of the Mekong River in the lower basin:

Decisions about resource use can be unrelated to sustainable resource management,

cross-sectoral integration. Recent proposals to
the Global Environment Facility have been commended and funded to establish interagency
communication entities that will integrate inland fisheries and the people that depend on
these into policies on development and management (GEF 2014). Furthermore, the guidance
agreed to at the international level for national
and regional implementation is frequently disconnected from national and regional decisions
that are often implemented in a manner inconsistent with international obligations. In the
lower Mekong River, for example, decentralized
governance resulted in local decisions being implemented that contravened the international
objectives of the Mekong River Commission in
regards to conservation of fish stocks (Barlow,
this volume; also see Box 2).

Box 3. Lessons Learned in the Laurentian Great Lakes Fishery

Canada, the United States, and a number of sovereign tribal nations border the Laurentian
Great Lakes. For centuries, management of fishery resources occurred through multiple
and separate management strategies by numerous government agencies throughout the
basin. After nearly a century of failed attempts at coordinated management between
these governments, the 1940s brought significant ecosystem and fishery changes when
alterations of waterways for commerce resulted in the introduction of harmful invasive
species into the ecosystem. The resulting demise of commercially valuable native fishes
had very serious socioeconomic consequences at the local and regional levels, which
provided the impetus for the multiple jurisdictions to cooperate and share information
to rehabilitate the fish and fisheries of the Great Lakes. This ultimately culminated in the
1955 establishment of the Great Lakes Fishery Commission (GLFC), tasked with controlling the invasive Sea Lamprey Petromyzon marinus and coordinating fishery research
and management for fish populations of common concern (Gaden et al. 2013).
Further, the GLFC facilitates accountability and transparency through the 1964 creation of lake committees—one committee for each lake (GLFC, no date; Gaden et al. 2013).
These committees provide opportunities for the nations, province of Ontario, states, and
tribal (U.S.) governance organizations to meet and exchange information, strategize on
regulations, and discuss issues affecting their respective lake and fish stocks of common
concern. These committees eventually enabled more effective basinwide cooperation.
During the 1970s, the basin’s governing institutions began discussions to develop a strategic plan to formalize their agreement to cooperate and apply an ecosystem approach
to Great Lakes fishery management. This strategic plan was adopted in 1981 and today
provides for the mechanism that has resulted in effective strategies to rehabilitate productive fisheries in these shared water bodies, A Joint Strategic Plan for Management of
Great Lakes Fisheries (plan revised in 1997; GLFC 2007; Gaden et al 2013). The success
of this forum has been instrumental in rehabilitating Great Lakes fisheries and coordinating fishery regulations across jurisdictional boundaries.
proach that considers all sectors has been
discussed for more than a decade (Committee
on Fisheries 1999). Although the terminology
may have changed, the message has been the
same: integrated resource development and
management is essential. Several case studies in this paper examine why a freshwater
resource governance approach failed while a
few assess successful case studies related to
fisheries. The majority of case studies, however, do not focus on how to better access
and communicate the contributions of inland
fisheries to economic, social, and ecosystem
well-being. The efforts at freshwater gover-
nance instead usually focus on how to best
use water resources for the benefit of a specific sector.
This narrow focus and lack of comprehensive vision have undermined fishery management. The focus on a specific economic
sector’s water needs have oriented resource
management toward addressing economic
objectives, thus ignoring the management of
freshwater resources to support social and
environmental demands. The discussion below considers how elements identified as
contributing to effective governance can assist in better communicating across sectors

261
Box 4. International Guidelines Contributing to Food Security
and the Role of Inland Freshwater Resources
reBeCCa meTzner anD Carlos FuenTevilla
International guidelines can provide stakeholders with a framework for creating a participatory governance approach and clarifying stakeholder rights that contribute to food
security from terrestrial and aquatic ecosystems. Guidelines regarding tenure rights are
expected to reduce the risk of overexploitation, which occurs when groups or multiple
individuals claim overlapping tenure rights (FAO 2012). Insecure tenure rights facilitate
corruption, as has been shown by the Food and Agriculture Organization of the United
Nations (FAO) and Transparency International finding that land administration is one
of the most corrupt public sectors in the world, particularly burdening the poor and especially women who make essential contributions to agriculture, fisheries, and forestry
in developing countries (Transparency International 2011). Voluntary Guidelines on the
Responsible Governance of Tenure of Land, Fisheries and Forests in the Context of National
Food Security (FAO 2012) noted the need for strengthening and securing tenure rights
and developing capacities for stakeholders to fully take charge of their responsibilities
to manage their resources sustainably in the long and short terms. Equally as important,
the institutions that govern tenure of land, fisheries, and forests need to adapt to the
growing pressures on the use of natural resources and change how these resources are
used. Governing institutions should also adapt to the growing intensity of competition
for natural resources and its effects across sectors. Doing so requires strengthening local
organizations and groups (e.g. producers) facilitating the needed intersectoral dialogue
and collaboration for enhanced food security and fisheries sustainability (FAO 2012).
The International Guidelines for Securing Sustainable Small-Scale Fisheries (SSF),
recently adopted by FAO (2014), identify the rights of the individual and the contribution
of SSF to food security and poverty eradication. The SSF promotes the development of
initiatives for poverty alleviation, equitable social and economic development, improving governance of fisheries, and promoting sustainable resource use. In particular, the
guidelines stress the importance of respecting and realizing human rights and dignity
and the need for gender equality, as well as encouraging countries to ensure that smallscale fishers are represented in decision-making processes that affect their livelihoods.

and, thus, elevating the contribution and importance of inland fish and fisheries in the
governance of freshwater resources.
Participation
All stakeholders and sectors should be included in decisions regarding freshwater resources. Inclusive representation is not just
ethically good, it has practical applications
as well. Incorporating traditional knowledge
can offer insights comparable to expert scientific analysis (Chalmers and Fabricius 2007).
In addition, bringing in all stakeholders to
discuss strategies for sustainable use and enforcement of regulations can be an important
factor in helping to improve development of
management policies and plans, increasing
compliance, and making it easier to adapt
regulations to fit changing circumstances
(Pomeroy 1994). Last, by involving all stakeholders, it may be feasible to consider, from a
social and an environmental perspective, the
costs and benefits of proposed activities and
implement actions accordingly (FAO 2010a).
Previous efforts to increase stakeholder
participation suggest that a forum that ensures representation from all sectors using
freshwater is needed when developing policies. To successfully achieve collaborative
and coordinated governance, sectors must
engage as partners, to effectively influence
the outcomes of the governance process. Participation among governments also needs to
be improved through, inter alia, the creation
and implementation of lake and river basin
authorities on shared water bodies (Table 3).
Each sector or government also must ensure
that they can provide representatives that
have the necessary skills and knowledge to
engage in the process (Box 5).
Such collaborative approaches can take
a long time and require trust between sectors. Additionally, many stakeholders involved in inland fisheries are still not aware
about their rights and obligations (Margaret
Nakato, World Forum of Fish Harvesters and
Fish Workers, personal communication) and,
therefore, finding effective participants may
be difficult in some areas. Efforts are needed
to ensure equity and rights of all stakeholders
(Table 1).
Transparency
Transparency ensures that interested parties
have access to information and are informed
about rules, procedures, impacts of decisions
on other sectors, and other relevant information (Heald 2006; Weiss and Steiner 2006;
Etzioni 2010; Table 1, Issue: Improved communication among users of freshwater is essential). Transparency is achieved through access
to reliable information requisite for informed
discussions about the synergies and tradeoff opportunities existing among freshwater
sectors (Vishwanath and Kaufmann 2002).
Transparency requires clear communication;
especially challenging is communicating information in a timely manner and in a format that
is easily understandable to policymakers and
stakeholders (Lynch et al. 2011). If stakeholders either do not have access to the information
or the information is incomplete or not understandable, transparency is not truly achieved.
Accurate communication of the results of discussions, as well as the success or failure of
management actions, is an essential component of transparency. Providing a transparent
process also attracts participation by informed
stakeholders and facilitates implementation
and enforcement by having stakeholders that
are supportive of decisions (McGarrell et al.
2013). Improving communication and encouraging cross-disciplinary integration may enhance transparency by reducing the challenge
of accessing and understating information
from the various sectors (Box 5) and engaging
outreach and communication specialists.
Accountability
Accountability is a critical aspect to ensuring
that governance processes and management
actions result in the agreed outcomes. Accountability must exist between stakeholders and those charged with the responsibility
to govern and manage freshwater resources
(Béné and Neiland 2006). Accountability requires clear, measureable, and enforceable objectives related to all outcomes and allocation

Box 5: A Sliver of Water—Overcoming Barriers to Cross-Sectoral
Governance
John Fazio, Jim ruFF, anD nanCy J. leonarD
A portion of the millions of acre-feet of water in the Columbia River basin’s hydrosystem are currently allocated for mitigating hydrosystem impacts on fish and wildlife. This
sliver of water, called the water budget, averages about 10% of the hydrosystem’s energy
generation and ranks third in priority when making hydrosystem operating decisions:
flood control being first and emergency power generation being second. Recognizing
the need and achieving cross-sectoral agreement to allocate water for fish and wildlife
affected by the hydrosystem’s operations is an impressive accomplishment. Prior to the
1980s, Federal Columbia River Power System operators officially recognized two water sectors in their decision-making process, agricultural irrigation and hydroelectricity
generation (USDOE et al. 1995; J. Fazio, 2006 memorandum to Northwest Power and
Conservation Council members, on multiple purposes of the Columbia River hydroelectric system). The U.S. Army Corps of Engineers has flood control jurisdiction over
all Columbia River reservoirs in Canada and the United States (Fazio, memorandum).
Coordination of the Columbia River Basin’s freshwater did not explicitly consider fish
and wildlife. This omission had been attributed to the tribes’ and the fish and wildlife
agencies’ lack of political support and understanding of the hydrosystem’s power system planning processes and operations. Thus, the planning and the operation of the hydroelectricity system reduced flows in a manner that degraded the aquatic habitat for
fish, increased migration time for juvenile salmon, and exposed them to higher predation rates (NPCC 1982). The Northwest Power Act of 1980 gave fish and wildlife needs
“equitable treatment” with other purposes, particularly hydropower. To address the lack
of understanding, it was necessary for the fishery management agencies and tribal representatives to speak the language of the power system and to speak with one voice. The
1982 and 1984 Columbia River Basin Fish and Wildlife Program provided the policy
guidance about how to integrate fish flow requirements in power system decisions. This
guidance ensured that fisheries experts are included in the hydrosystem planning and
operation process by providing the needed resources and political support. The combination of efforts to improve juvenile salmonid survival during the 1980s and 1990s,
including changes in water flow, installation of both surface and screened bypass systems, and increased spill have all contributed to improved conditions for fish and higher
juvenile survival ( Williams et al. 2001; Muir and Williams 2012).This river management
approach, applied since the 1980s, appears to be successful as it has continued to be
applied for the past three decades with all water sector needs being met somewhat adequately, although not to the full satisfaction of each sector (see Box Figure 5.1 below).
Box continues
consequences. As such, there needs to be sufficient information to determine whether policies and resultant actions contribute towards
achieving these objectives. It is also important
to be clear about who is accountable to whom,
in what ways, and in what time frames actions
and results will be reported. However, accountability often remains undefined and vaguely
alluded to in governance processes (Béné and
Neiland 2006).

bartley et al.
Box 5. Continued
Figure 5.1.—Change in water allocation amount irrigation and hydroelectricity (power)
generation following the implementation of the water budget. The water budget allocated
water for fish needs, such as during salmon migration.
Governance of freshwater resources often
has clear processes by which the governing
institutions account for their decisions to agricultural and hydroelectricity stakeholders (e.g.,
why certain amounts of water or electricity are
made available at a given price). Conversely,
accountability for freshwater allocation decisions impacting the fishery sector has tended
to remain nebulous. Part of the problem with
making institutions accountable is the difficulty in ascertaining the impact of changes in
freshwater quality and quantity on fisheries,
aquatic species, and their habitats. For the governance process to work effectively, governing
institutions must take measures to be accountable to all freshwater sectors impacted by their
policies and decisions (Boxes 1 and 6).
Access, human rights, and equity
Good governance should ensure fair and equitable access to resources and to the benefits
derived from the use of those resources (Onyango 2000). A human-rights-based approach
can help clarify and organize governance issues related to food security and nutrition by
(1) providing for basic rights, primarily the
right to food (e.g., the 1948 International Bill
of Human Rights, the 1979 Convention on
the Elimination of All Forms of Discrimination against Women, and the 2007 United Nations Declaration on the Rights of Indigenous
Peoples); and (2) the right to access resources
(e.g., FAO 2012).
As land and water resources are developed
and thereby made more valuable, access to
those resources is often given to new users at
the expense of traditional users (e.g., in Bangladesh, valuable fisheries were created in oxbow
lakes, but traditional fishers were prevented
from accessing the water bodies [Nurul Islam
et al. 2014]). Addressing fair and equitable access to a fishery, however, is not sufficient; it is
effective governance of fisheries and freshwater resources
Box 6. Accountability through Flexibility and Partnerships in
River System Planning
krisTin meira
With so many activities and interests on the Columbia River system (USA), governance
occurs to varying degrees at local, state, regional, national, and international levels.
Freshwater sectors, including agriculture, irrigation, hydroelectricity, fisheries, have
struggled with how to assess and report to their stakeholders about how they are utilizing freshwater while improving conditions for endangered salmon and steelhead (anadromous Rainbow Trout Oncorhynchus mykiss). The common thread woven through these
layers of oversight is the desire to hold accountable all those involved in decisions related to river system activities for impacts on northwest fish populations.
In 2009, the federal agencies responsible for implementing and reporting on listed
species included an Adaptive Management Implementation Plan (AMIP) as part of the
Federal Columbia River Power System (FCRPS) biological opinion. The AMIP was the result of an intensive review of the 2008 biological opinion, including listening to the views
of parties to the FCRPS biological opinion litigation, fisheries management agencies and
independent scientists, and consideration of points raised by the judge overseeing the
FCRPS biological opinion U.S. District Court case. The AMIP serves as an accountability
tool that consists of biological objectives and indicators to detect and report on declines
in abundance of salmon and steelhead listed under the Endangered Species Act. The
AMIP facilitates implementation of a rapid response set of contingency actions to address unexpected declines in abundance. The goal is to create a plan for operating the
river system that is flexible enough to respond to changing conditions. The plan also
provides guidance to improve efforts to track and detect climate change and its effects
on listed salmon and steelhead species. This plan also considers other factors that could
emerge during the 10-year life of the biological opoinion that may impact the abundance
of listed species.
These biological indicators and contingency actions added a level of transparency
and accountability by requiring agencies to more frequently report the status of the
endangered salmon and steelhead and clearly describe what course of actions will be
taken if a significant decline in abundance is detected. In addition to heightened monitoring and enhanced planning, more collaboration is occurring on the Columbia River
than ever before. In 2008, sovereign tribes signed landmark agreements with several
U.S. states and federal agencies. The Columbia Basin Fish Accords cleared the way for
US$900 million in salmon restoration projects throughout the Columbia River basin over
10 years (CRITFC 2008). It also signaled improved partnership between parties that had
previously been on opposite sides of the courtroom. In the first 5 years of their work,
the Columbia Basin Fish Accords partners delivered new spawning habitat, protected or
improved more than 175,000 acres of fish and wildlife habitat, and protected more than
35,000 acre-feet of water (Columbia River Basin Federal Caucus 2014a, 2014b). These
benefits demonstrate the progress that can occur when parties are able to work together
rather than meet solely in litigation.

equally important to ensure fair and equitable
access to the water where fish live, to the land
where fishing activity takes place, and to the
markets where they are sold.
Governance processes should treat men
and women equitably. Men and women often
play different roles in the fisheries, with men
more involved in harvest and women more involved in postharvest activities (Weeratunge
et al. 2010). In particular, attention needs to be
given to how the loss of access to inland fish
resources along the complete production chain
impacts a community, especially the vulnerable and marginalized people often in smallscale inland fisheries (e.g., HLPE 2014).
Human rights are incorporated into governance aspects through, inter alia,

participation,
accountability,
nondiscrimination,
transparency,
human dignity,
empowerment, and
rule of law.
The above elements, named PANTHER
(FAO 2014e), focus on the underserved groups
(such as small-scale producers, indigenous
people, and women) whose food security is
most vulnerable to changes in inland freshwater fisheries (Box 7).
Ecosystem well-being
The cumulative costs to aquatic ecosystems
and human well-being can be quite high when
ecosystem well-being is not considered in governance of freshwater resources (Table 3).
Costs to the ecosystem include species extirpations, deterioration of aquatic habitat, and loss
of ecosystem services. Expensive restoration
efforts are a long-term cost to human well-being. Human health costs include reduced availability of protein and costs of land-based agricultural and aquacultural projects (MA 2003).
Often decisions that result in these costs are
based on flawed economic analyses, which calculate the monetary benefits of large-scale development while improperly considering the
full range of costs and loss of ecosystem ser-
vices. This likely occurs because the benefits
of the development are easily calculated as the
net income of a single or small number of businesses while the costs in terms of loss of ecosystem services are externalized and dispersed
between the environment and society.
Sustained ecosystem well-being needs to
be a critical outcome of governance processes
(Pasqual-Fernández and Chuenpagdee 2013)
as it is the basis for production for freshwater
fish and fisheries. The importance of ecosystem well-being to social and economic wellbeing is gaining attention at higher levels of
governance (MA 2005; FAO 2009). Indigenous
peoples have long recognized that the unique
relationship between land, water, and species
is central to sustaining their culture, governance, communities, and economies (Box 7).
Numerous international organizations have
developed instruments and criteria for sustainability and, thus, ecosystem well-being. Some
examples are the FAO Code of Conduct for Responsible Fisheries (FAO 1995) and more specialized instruments such as ecolabeling guidelines for inland capture fisheries (FAO 2010b)
and the aquaculture certification guidelines
(FAO 2012b). Ecosystem well-being, however, needs more attention in the governance of
freshwater resources, including fisheries.
Capacity
If there is insufficient capacity to develop and
implement policies and support the institutions needed for management of freshwater
resources, including fisheries, it is unlikely that
the desired outcomes will be attained (e.g.,
upper Volga case study, Box 8). For a crosssectoral governance process or institution to
succeed, it needs to have adequate knowledge,
human and financial resources, and authority
for implementation (Béné and Neiland 2006;
Schechter and Leonard 2008). To achieve adequate capacity, the role and needs of the public
sector, private sector, and civil society organizations all need to be considered, and communications and linkages among them enhanced.
Improving economic growth and human development (Sako 2003) may also improve capacity for cross-sectoral governance, as long
effective governance of fisheries and freshwater resources
Box 7. Role of Rights Holders in Fisheries Governance
Pauline TerBaskeT anD Jay Johnson
A strong role for local title and rights holders in the governance of fish, fisheries, and
their watersheds is often a critical determinant to ensuring the sustainability of fisheries and aquatic ecosystems. These key rights holders can provide valuable knowledge
to ensure the sustainability of the natural resources, and their support is necessary for
successfully implementing and enforcing actions that provide for sustainable fisheries.
When rights holders and fishers are not meaningfully included in governance structures,
governance that ensures sustainable outcomes is not and cannot be effective.
The legal title and rights of the Okanagan (Syilx) Nation to its fish and territory, including the transboundary Columbia River, are increasingly recognized given its status
as the local historical indigenous community. The traditional knowledge and the deep
and unique relationship of the Okanagan Nation to the land, water, and species that are
central to sustaining its culture, governance, communities, and economies have largely
been ignored and marginalized by Canadian federal and provincial governing institutions. One of the biggest fisheries tragedies faced by the Okanagan Nation was the devastation of the salmon stocks that are the lifeblood of the indigenous communities. Dam
construction in the Columbia River basin and the U.S.-based hydroelectric industrialization of the Columbia River reduced salmon abundance and prevented salmon passage to
access the upper reaches of the Canadian Columbia River system. This loss of the salmon
in key parts of the Columbia River remains a historical injustice. Efforts to address some
of these past injustices includes U.S. legal challenges based on indigenous rights to restore the role of tribal and First Nations groups to a stronger governance role in the river
system.
These legal and governance successes, combined with traditional restoration prescriptions, have begun to restore the habitat and environmental conditions necessary
for salmon survival in parts of the Columbia River system. While the upper reaches of
this river salmon remain blocked, intervention and restoration activities by the Okanagan Nation have led to an increase in the annual Sockeye Salmon Oncorhynchus nerka
returns in the Okanagan river portion from the near extinction numbers of 3,500 in 2005
to more than 300,000 Sockeye Salmon in 2015. The Okanagan Nation, in collaboration
with U.S. tribal partners who exercised their indigenous treaty rights first through the
federal courts (Boldt and Redden decisions, U.S. Supreme Court, 1975 and 2005) and
then through negotiations with all parties involved, resulted in increased seasonal water
flows over dams, increased support and recognition for indigenous peoples informed
habitat restoration projects, and better fish passage structures, all of which are critical
for salmon survival and restoration. Today, due to indigenous leadership, collaborative
fisheries management, and a broader social demand for environmental sustainability
that incorporates the traditional knowledge of the people who are most affected by these
resources, the salmon are returning! Recent successes, such as the salmon returning
from near extinction in other portions of the Okanagan Nation’s territory, are providing
hope that with great effort and collaboration, the historical injustice of the loss of salmon
in the upper portions of the Columbia River will too be overcome.

Box 8. Incorporating Local Knowledge and Rights into Fisheries
Governance
DmiTry Pavlov anD Bakary kone
Local knowledge and recognition of existing rights are crucial factors in effective fisheries governance. When these are not appropriately considered, it can be very difficult to
sustainably govern and safeguard existing fishery resources, as the following examples
from the upper Volga river (Russia) and inner Niger delta (Mali) illustrate.
Upper Volga River
In 2007, commercial fishing was banned in two of the upper Volga reservoirs. It was
expected that a decrease in the fishing pressure would result in the recovery of valuable
fish stocks. However, after 6 years, not only had the stocks not recovered, they had continued to decline. The main reason for this was a change in access, which changed how
fishers approached their fishery resources. Historically, the fishing grounds were granted to commercial fishers on a long-term basis. These fishers were usually organized in
some form of collective enterprise (e. g. cartels or family companies), which treated the
fishing grounds as their own property and protected fish stocks in collaboration with
the state fishery authority. Forms of collaboration varied from patrolling the waters to
informing the guards about illegal fishing. The ban of commercial fisheries resulted in
the lack of this protection, with the state fish guard unable to provide efficient control of
poaching (D. Pavlov, personal observations).
Inner Niger Delta
In the inner Niger delta (IND) of Mali, fisheries diversity and harvest are controlled by
the flood regime. Traditionally, the maitre d´eau of the Bozo was the water master in
the inner Niger delta (Wymenga et al . 2012). The maitre d´eau is at the center of the
group of fishers and has three essential rights: (1) annually renewing the sacrificial pact
with the spirits of the river, (2) deciding on the establishment of the largest permissible annual fisheries, and (3) regulating the practice of fishing. The maitre d´eau owns
specific fisheries (to which he has an exclusive right or privilege). The disruption to the
traditional governance approach, due to numerous factors, including the conquest of the
IND by immigrants and occupiers, the centralization of power in the management of
resources by the national government, and the loss of powers of traditional managers of
natural resources such as maitre d´eau of the Bozo, has severely impacted the sustainable management of this region’s natural resources. Currently, an effective mechanism is
lacking for coordination of water management across scales (local, regional, and national) and between upstream (hydropower) and downstream (fishers) users of freshwater
resources. Thus, dams on the upper portion of the Niger, which control the water level,
negatively impact fish production downstream in the IND area. Additionally, there is no
mechanism that allows downstream users to have a voice when decisions concerning
upstream (dam) water use are made. The main constraints facing fisheries governance
in the IND are that (1) traditional maitres d´eau are no longer involved in decision-making processes, with their authority instead being transferred to local mayors; (2) there

is an increasing number of fishers; (3) prohibited fishing techniques are being used; and
(4) there is little implementation and enforcement of fishery laws and regulations; all
of which has led to a reduction in the sustainability of IDN fishery resources (see also
Wymenga et al 2002, 2012; Zwarts et al. 2005; Beintema et al. 2007; Kone 2012; and van
Beukering et al 2013).
as the above aspects of good governance are
maintained.
Opportunities for Improvements
Overall, global, national, regional, and local efforts to improve the governance of inland fish,
fisheries, and freshwater resources need to be
strategic and comprehensive in breaking down
sectoral segregation. There is general agreement that opportunities for improvement in
freshwater resources governance exist when
applying an inclusive landscape and ecosystem
approach (Box 4; Liu and Taylor 2002; FAO
2009, 2013). These discussions and recommendations, however, rarely explore how this
approach can be practically implemented (e.g.,
ISAB 2011). Areas of opportunities and potential solutions, including recent actions that
may facilitate progress, are highlighted below.
Strengthening governance of the isheries
sector
More holistic approaches to governance of
the fishery sector are needed, involving fisher
groups and other freshwater sectors, as well
as participants along the entire fisheries value
chain (e.g., harvest, processing, marketing, and
distribution; Table 1). As guidance approaches
and tools for effective cross-sectoral governance are developed, there will be opportunities to implement and improve current governance, as long as policymakers determine that
it is worthy to invest in these improvements.
For example, the FAO Committee on Fisheries
recently produced voluntary guidelines to improve the governance of small-scale fisheries,
which will help policymakers make informed
decisions, avoid conflict within the fishery sector, and ensure responsible use of freshwater
resources (Box 4; FAO 2014b). Improvements
include well-designed fisheries governance
processes, better management across all inland
fisheries, better integration along the entire
fisheries value chain from capture to consumption, and, last, governing fisheries within its
larger ecosystem context. Existing governance
processes differ in their adequacy to govern inland fish and fisheries, irrespective of the type
of fisheries (commercial, recreational, subsistence small-scale). In many South American
river fisheries, for example, a centralized management framework supports a harvest-oriented market approach directed to maximize
economic returns through intensive exportation fisheries (Baigún et al. 2016, this volume).
This framework in South America does not
recognize management issues relating to the
conservation of aquatic resources, improving
socioeconomic benefits, and welfare of fishing
communities. There are some examples in the
Amazon River basin of successful management
for multiple outcomes (Baigún et al., this volume), and these approaches need to expanded
to other watersheds and be integrated as part
of regular management programs more widely.
Current governance regimes have a tendency to partition fisheries governance based
on the type of fisheries instead of applying a
holistic governance approach. For instance,
governance regimes have tended to partition
fishing areas (i.e., zoning) between small-scale
fisheries and larger-scale fishing operations,
but these zones are weakly enforced and do not
resolve the inability to limit access and fishing
effort (Committee on Fisheries 2011). Improv-
270
bartley et al.
ing governance for all fisheries requires understanding and consideration of the pressure
exerted on the resource by fishers so that one
group of fishers is not detrimentally impacted
by another. Achieving this level of comprehensiveness will contribute to achieving economic,
social, and ecosystem well-being (FAO 2014b).
Fishers, markets, producers, and consumers are often considered separately in governance structures with little consideration for
how these interrelate. Considering all fishing
operations and the entire fisheries value chain
will enhance the fishery sector’s ability to communicate effectively about the overall value of
fisheries and the requirement for freshwater
during the development of future allocation
policies. The expected benefits of applying this
integrated approach to freshwater fisheries
mirror those for marine fisheries, which facilitate fishery sustainability by incorporating reliable traceability systems that allow tracking
fish from harvest to the market (UNEP 2009).
Valuation of inland isheries
Understanding the value of inland fisheries
to societal and human well-being is an aspect
of inland fisheries that needs to be improved
(Table 1). The current obstacles to determining and communicating inland fisheries values partially arises due to lack of data and the
challenge in communicating the value in terms
meaningful to policymakers and the public.
Inadequate monitoring of small-scale fisheries is the norm in many countries. As a consequence, there is a paucity of data about the
status of stocks, numbers of fishers, and the
socioeconomic values of the resource (see Economic and Social Assessment and Biological
Assessment themes, this volume). The lack of
quantitative information leaves the fishing sector in a weak negotiating position compared
to other sectors (e.g., hydropower, irrigation,
and navigation) that can more easily document
the economic contributions of their industries.
Inland fishery management agencies would
benefit greatly from rigorous studies that demonstrate the multiple values of their fisheries.
Different approaches to valuing inland fish
and fisheries have included determining
•
•
•
•
•
•
the economic value of the recreational the
fishing industry (Southwick Associates
2013),
the nutritional contributions of inland fish
(Thilsted 2013; Roos 2016, this volume);
the ecosystem services, including the role
of fish in food webs (e.g., supporting piscivores such as the grizzly bear; Johnson
and O’Neil 2001);
the historical and cultural values (Box 7);
the scientific value of fish (e.g., as laboratory models in toxicity and genetic studies;
Ribas and Piferrer 2014); and
the nonfood commercial value of fish (e.g.,
in identifying antifreeze proteins that may
contribute to biotechnology advances; Yamashita et al. 2014).
Depending on the situation, a combination
of these approaches may be communicated effectively to policymakers.
Working together
Efforts to improve the governance of inland
fisheries and freshwater resources need to be
strategic and comprehensive (Table 1). There
are important international partners for addressing water and food security that the fishery sector should engage, including, inter alia,
the World Water Forum, the Water Governance
Facility, the Global Water Partnership, the Organization for Economic Cooperation and Development, the Initiative on Water Governance,
and the World Water Council. An FAO-commissioned report (McInnes et al. 2014) that evaluated institutions for their potential to effectively engage inland fisheries issues revealed
an additional 10 entities whose opportunity
for action and relevant mandate would indicate that strategic partnerships with the inland
fishery sector would be beneficial (Figure 1).
Sectoral approaches will be difficult to change;
the above report further stated that FAO needed to better integrate inland fisheries into its
own program of work.

vation activities are vitally important (Table
1). Increases in food demand may be met by
intensifying domestic production, which may
threaten aquatic biodiversity that is extremely important for local food supply and livelihoods (Bharucha and Pretty 2010). In areas
where water and terrestrial resources uses
merge, as happens in most floodplains, it is
critical to maintain ecological processes to assure that fisheries, agriculture, cattle ranching,
and so forth can be developed in a sustainable
way according to natural conditions. In the
Paraná Delta, for example, increased intensive
land-use practices supported by development
of embankments and levees have promoted
changes in land use that are negatively affecting floodplain fisheries (Baigún et al. 2008). In
the Lake Chad basin where households are actively involved in fishing, farming, and herding
(Béné et al. 2003), fishing is a major activity in
all households at all income levels. Agricultural
landscapes are being replaced by ecoagriculture landscapes, where biodiversity conservation is a stated management objective in rural
development (Scherr and McNeely 2008). This
change is beginning to occur in policy discussions such as in Laos, where Bharucha and
Pretty (2010) advocate the integration of conservation policy, food policy, and agricultural
policy to recognize and preserve the importance of wild foods. Recognizing this reality,
new approaches to governance and resource
management must acknowledge and address
the numerous interrelated aspects of food production and conservation activities in many
rural communities
The Future and Recommendations
for Better Governance
The first United Nations water development report stated that the “water crisis is essentially a
crisis of governance” (UNESCO 2003). This crisis directly impacts inland fisheries and freshwater ecosystems. The diffuse nature of inland
fishery resources and the numerous users of
freshwater ecosystems render achieving effective governance a complicated and difficult goal.
Application of the ecosystem approach to fisheries has generally been focused on marine fish-
eries and has often only been considered to be a
sectoral approach (i.e. only dealing with issues
under the control or influence of the fishery
sector; Box 3). Efforts to include consideration
of inland fisheries in cross-sectoral ecosystem
based approaches have not been overly successful (UNEP 2014). Nevertheless, these efforts are
crucial as the socioeconomic contribution of
inland fisheries to poverty alleviation and livelihoods must be understood (Béné et al. 2007).
An ecosystem-based approach is needed for
multisectoral integration, effective governance,
and continued contribution of inland fisheries
to food and nutritional security. If this approach
is not adopted, history has shown that the fisheries and freshwater resources deteriorate to
the point of significantly reduced benefits being
provided, including a decline in food security for
communities.
Achieving cross-sectoral, integrated governance of freshwater ecosystems and their
fisheries will require fishery managers, policymakers, and ministers to engage broader,
more multidisciplinary audiences and to form
new partnerships (Box 5; Table 1 Issue: Crosssectoral integration is lacking in development
agendas for freshwater ecosystems). The FAO
Committee on Agriculture convened a recent
session on water governance for agriculture
and food security, wherein terrestrial agriculture presented a case for improved governance. The fishery sector was not represented
(D. M. Bartley, personal observation) but obviously would have been a valuable participant
in this intergovernmental discussion. Clearly,
there is a disconnect between each sector’s impact on others, further emphasizing the need
for a new integrated governance structure and
a more interdisciplinary work force that can effectively communicate to multiple sectors the
cost and benefits of policy decisions.
A first step to achieve this integration may
involve having the fishery sector engage important international partners that address
water and food security. The fishery sector, to
engage with other sectors, will want and need
justification to approach these other sectors.
The donor community that funds research,
as well as development and conservation activities, is recognizing that integration among
effective governance of fisheries and freshwater resources
sectors is important and is taking action that
encourages integration in the work that the donor community funds (GEF 2014).
While characteristics of good governance
may be easily outlined, transitioning to such a
status is difficult and requires clear perspectives and a properly sequenced process (Committee on Fisheries 2012). Fishers and fishing
communities need to be consulted, fully engaged, and aware of the various approaches
to manage fisheries and of their own options
for diverse livelihoods over the shorter to longer terms. Other water resource users must
become aware of the value of inland fishery
resources. Communities lacking current or
emerging basic needs (e.g., adequate food and
water) are the most in need of good governance
but may be unable to engage in the governance
processes unless empowered to do so and have
their other needs effectively addressed on a
short and long-term basis.
Short-term transition measures
Any endeavor to improve fisheries and inland
freshwater resources has to commence with intense consultation and awareness-raising with
the local community, policymakers, and practitioners (Table 1, Issue: Improved communication among users of freshwater is essential). To
establish the needed critical information about
the fishery, the fishers and concerned communities must be involved in the process to build
trust, confidence, and ownership that will support improved governance. Fisheries agencies
will need to cooperate with other government
departments, such as environment, health,
education, and water, and meaningfully engage
with the private sector, nongovernment organizations, and community organizations. For
the short term, identifying management measures that can generate quick improvements
in terms of cost savings, increases in food security, livelihoods and societal prosperity are
a priority. Demonstrating the benefits of this
transition early in the process is important to
get widespread support. In the inland fisheries sector, the priority short-term measures
should address reducing capacity where this is
an issue and should focus more on engagement
273
of other sectors to improve fish production and
ensure access to food and livelihoods (Committee on Fisheries 2012).
Medium- to long-term transition measures
Effective governance of inland freshwater resources may require applying a system that formalizes allocation among sectors (Table 1). This
change will take time to establish the appropriate legislative framework. The process for this
change will need to be based on a thorough
evaluation of the strategy for social and economic development of the sectors using freshwater. For inland fisheries, allocation among the
various users of freshwater is critical. Establishing allocations among users may require not
just an amendment of the fisheries laws and
regulations, but also political engagement for
additional reform, such as the country’s constitution. This will also require recognition of possibly competing interests between industrial
and smaller-scale sectors and between local, national, and international aims. In parallel to legal
reform, local and provincial fisheries and water
management plans may also need to be developed or altered through a participatory, interdisciplinary, integrated, and inclusive planning
process. Central to the above concepts is the
need to develop and apply a holistic approach
to fisheries governance (Garcia and Cochrane
2005) to promote strong stakeholder involvement and adaptive management as main pillars
for long-term successful governance.
Achieving these medium- to long-term
transition measures may aid in rebalancing resource distribution, which, in many developing
countries, favors nonfisheries sectors. This rebalancing by allocating resources towards inland fisheries could result in aiding (1) smallscale producers who would directly benefit
from improved access to resources that contribute to poverty reduction and food security,
and (2) other sectors by reducing conflict and
improving the efficiency, profitability, incomes,
and livelihoods of the workforce. Likewise, in
many cases, fishing capacity must also be managed and, in some cases, reduced or redistributed among subsistence, commercial, tribal,
and recreational fishing.
274
Outlook into the future
bartley et al.
Improved governance in inland freshwater
resources and inland fisheries cannot be pursued in isolation of other social, economic, and
political processes. Indeed the case for reform
needs to be seen and implemented within that
construct. Thus, the first task is connecting the
fishery sector, its people, and its issues, with
broader development processes at local, regional, and national levels. It is equally important to
ensure adequate recognition of the fishery sector’s role, and build the knowledge base and political capital needed to bring about positive and
sustainable change to freshwater resources governance. These connections should also serve to
raise awareness about the strong relationship
between the different human impacts that occur at local, regional, and basin scales and their
effects on fisheries resources. Of particular concern is how the hydroelectricity sector can affect
fluvial ecological integrity, particularly where
large dams and reservoirs are planned that
could lead to severe fishery habitat degradation.
The international development community can assist in transiting to good governance
by recognizing the cross-sectoral nature of the
problem and its solutions. The fisheries sector
must realize that engagement of the other users of freshwater is mandatory (Figure 1; Box
1; Table 1). For this increased collaboration to
succeed, significant developments are needed
in building partnerships and exploring effective
mechanisms of change and trust-building supply-and-value chain into governance structures
so that incentives are effectively reinforced and
information is communicated appropriately.
We propose recommendations in six key areas that we believe are important for improved
governance and responsible management of inland fisheries (Table 3). The path towards better governance of inland freshwater resources
is clear. The challenge will be in getting crosssectoral support to follow that path and produce leaders and policymakers who embrace
cross-sectoral collaboration and sectoral reform where needed. The experience with integrated resource management, whether called
an ecosystem-based approach, integrated water
resources management, or integrated coastal
area management, has not been overly positive
(Hefney 2013). Even at FAO, the United Nations’
specialized agency with fisheries and aquaculture, forestry, agriculture and natural resource
management departments, the integration of
sectors has been lacking (McInnes et al. 2014).
Although difficult, integrating the various sectors into an equitable, productive, and sustainable system of governance for inland fisheries
and freshwater resources will be essential for
the livelihoods of millions of people dependent
on freshwater ecosystems.

Conlicting Agendas in the Mekong River:
Mainstream Hydropower Development and
Sustainable Fisheries
Chris BarloW*,1
51/29 Thynne St., Canberra, Australian Capital Territory 2601, Australia
Abstract.—Development of hydropower dams on the mainstream of the Mekong River is highly contentious, particularly in Laos where two mainstream dams
are under construction and another seven are planned. The debate revolves predominantly around the economic development associated with increased electricity
supply and sales, versus the livelihood disruption resulting from the degradation
of the traditional uses of the river (primarily fisheries) and other ecosystem services. Assessment of policy and management indicates six lessons relating to the
governance of the Mekong and potentially other large transboundary rivers. These
are that decisions about resource use can be unrelated to resource management,
different public viewpoints and value judgments by political leaders must be acknowledged, integrated planning is essential for rational development of natural
resources, decentralization of government hinders sustainable management of
natural resources, technical information is essential for decision making and assessment of trade-offs, and difficulties in comparing monetary and nonmonetary values
encumber policy development.
The Geography and Traditional
Use of the Mekong River
The Mekong River is one of the world’s great
rivers. It extends about 4,900 km from the Tibetan Plateau in China to its mouth in southern Vietnam (Liu et al. 2009). It traverses
six countries—China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. For most of its
length, the river flows through mountainous
terrain before entering the lowlands of Cambodia and Vietnam, where it forms one of the
world’s great deltas. In China, the Mekong is
constrained by a comparatively narrow river
valley. As the river exits China and Myanmar,
its catchment broadens and numerous large
tributaries arise on the eastern side, in the Annamite Range of Laos, Vietnam and northeastern Cambodia. Several large tributaries also

flow in from Thailand to the west of the mainstream. Flow is predictable and highly variable
seasonally; average monthly discharges reach
a maximum of 40,000 m3/s in September and
a minimum of 2,000 m3/s in April (Adamson
et al. 2009).
Approximately 70 million people live in
the Mekong catchment, with about 75% living
in rural areas. Poverty is endemic, although the
poverty indices vary between rural and city
dwellers and among countries. Rural areas, especially in Laos and Cambodia, are characterized by a lack of paid employment opportunities, food insecurity, inadequate infrastructure
and services, and a high dependence on the
natural resources of the river and adjacent
lands (MRC 2010).
The capture fishery of the lower Mekong
River basin (that is, downstream of China) is
the largest freshwater fishery in the world,
with an annual yield of approximately 2 million metric tons per year (Hortle 2009). To
281
barlow
282
put this in perspective, it is about 2% of the
global fish catch, marine and freshwater combined. Freshwater fish and other aquatic animals constitute averages of 48, 47, 80, and 59%
of the animal protein consumed by people in
the Mekong basin regions of Laos, Thailand,
Cambodia, and Vietnam, respectively (Hortle
2007); that is, consumption of freshwater fish
and other aquatic animals nearly is equal and
often exceeds that of all other meats combined.
Other traditional uses of the river include
navigation, irrigation, and horticulture on the
banks of the river (river gardens). Importantly,
the river holds considerable cultural value for
the many communities in its catchment.
Governance of the Mekong
Governance of the Mekong water resource is,
in practical terms, divided into the upper and
lower reaches. The upper reach is in China,
where governance is comparatively straightforward as no other countries share that
stretch of the river.
The lower Mekong countries signed the
1995 Mekong Agreement, so forming the multijurisdictional Mekong River Commission
(MRC), with the intent of jointly managing
the shared water resources and sustainable
development of the river (see Mekong River
Commission for Sustainable Development,
www.mrcmekong.org). The MRC Secretariat
(MRCS) administers the technical work of the
agency. Its mandate is advisory. The power to
implement the MRCS’ recommendations rests
with the four national governments. The distinction between the facilitative and advisory
role of the MRCS and the implementing authority of the four member governments is often not appreciated by commentators and has
led to criticisms of the MRCS’ performance.
Complaints about the ineffectiveness of the
MRCS to sustainably and equitably manage
the resources of the Mekong may have credence, but the basis for the argument lies
more with the governance structure than it
does with technical performance. The highest
arm of the MRC is the council, which is comprised of water or natural resource ministers
from the member governments. Balancing
national and regional interests is problematic
for council members, with history showing
that national interests generally take precedence (Osborne 2009).
There are other less-formal interests that
variously impact the governance of the Mekong River. The geopolitical interests of China
extend pervasively into political influence
and economic integration with neighboring
countries. Decentralization of government is
a policy in Laos, which has allowed provincial
governors to make decisions about exploitation of natural resources with implications
stretching beyond their provinces. Policy decisions are often not based on evidence and
can be influenced by personal ideology and
opportunism. In the context of the Mekong,
evolution of policy is constrained in political
environments in which international commentary can be seen as encroachment on
hard-won state sovereignty and domestic
criticism can be construed as unpatriotic
(Dore and Lazarus 2009).
Hydropower Development and
Inland Fisheries
China has completed three large dams on the
Mekong and a further five are being built or
are planned. These dams have major impacts
on hydrology and completely block fish migration in the upper Mekong. Below the China–Laos border, the main impacts of the dams
are on dry-season flows, which are increased
as a consequence of stored water being released through hydropower generation, and
on suspended sediment, which is trapped by
the dams.
On the mainstream in the lower Mekong
basin, nine high-level dams are planned in
Laos (construction has started on two, the
Xayaburi and Don Sahong dams), and a further two are planned in Cambodia. Studies
by the MRC (e.g., Barlow et al. 2008; Halls
and Kshatriya 2009; Dugan et al. 2010; ICEM
2010) and others (e.g., Roberts 1995; Baran
and Myschowoda 2009; Osborne 2009; Orr et
al. 2012) have documented the severe impacts
these dams would have on fisheries yield and
food security, primarily because the dams act
conflicting agendas in the mekong river
as a barrier to fish migration, which in turn
affects breeding and recruitment. Substantial fish mortality is also predicted to result
from downstream passage through turbines
(Halls and Kshatriya 2009). Other ecological changes include those common to large
dams elsewhere, such as sediment trapping,
altered flow regimes, lowered water temperature downstream of dam outlets, and creation
of still water environments upstream of dam
walls.
In addition to the multiple benefits of increased electricity supply, the proposed dams
may improve river navigation and enhance irrigated agriculture due to increased dry-season flows (ICEM 2010).
Public debate about the dams has been
widespread and is ongoing. Opposition is
mainly centered on impacts on fisheries and
associated livelihoods, and the forced displacement of riparian communities (e.g., Save
the Mekong Coalition, www.savethemekong.
org.). Proponents in Laos argue the need for
electricity and income to lift the country out
of the Least Developed Countries category,
and that harmful effects of the dams can be
mitigated (see, for instance, Department of
Energy, www.poweringprogress.org).
The fisheries case has been recognized by
government management agencies in Laos,
albeit reluctantly and belatedly. In 2009, a
senior administrator concluded a technical
meeting on dams and fisheries by saying “Forget the fish; if we worry about the fish, we will
never have dams” (author’s personal observation). The approach has evolved since then
in response to the sustained public discourse
(e.g., Save the Mekong Coalition, www.savethemekong.org.) and MRC and other technical
reports (e.g., Halls and Kshatriya 2009; ICEM
2010; Orr et al. 2012) on the negative impact
of the dams on fisheries resources and fisher
livelihoods. In the case of Xayaburi Dam, which
will have a dam wall 32 m high and span the
entire river, fish passage (ladders and lifts) is
proposed as a means of ensuring upstream
migration of fish, deflectors and fish-friendly
turbines to facilitate downstream passage,
in conjunction with stocking of hatcheryreared fish. The fishway consulting company
283
for the Xayaburi Dam considers that, in its
experience, “there is always a solution to a
fish passage problem” (Fishtek Consulting,
www.fishtek.co.uk), but this seems contrary
to decades of experience and billions of dollars in research and development elsewhere
that indicate that lasting ecosystem-wide impacts of high dams cannot be compensated for
through fish passage and hatchery technology
(e.g., Agostinho et al. 2008; Williams 2008;
Ferguson et al. 2011; Brown et al. 2013).
The Don Sahong Dam is located on one
channel of the 11-km-wide Khone Falls in
southern Laos. The channel is the Hou Sahong, which is the major upstream route used
by migrating fish (Roberts and Baird 1995).
Proposed mitigation involves engineering
works to remove rocks, lessen gradients, and
widen the channels on each side of the Hou
Sahong, with the overall intention of making
the channels more accessible and functional
for migrating fish. The efficacy of the strategy
can only be assessed postconstruction.
Assessment of the impacts of the mainstream dams has, until recently, been largely
isolated from consideration of the full array
of dams being planned for both the mainstream and tributaries. Ziv et al. (2012) have
modeled impacts of various combinations of
mainstream and tributary dams planned for
construction before 2030 and have shown
likely reductions in migratory fish biomass
of up to 51% and up to 100 fish species becoming critically endangered. Kondolf et al.
(2014) analyzed the effects of different scenarios of current and planned dams on sediment transport. Under a definite future scenario of 38 dams built or under construction,
cumulative sediment reduction to the Mekong
delta would be 51%. After construction of all
planned dams, cumulative sediment trapping
would be 96%. The impact would be severe,
not only on freshwater fisheries and agricultural productivity, but also on the marine fishery dependent on the outflow of the Mekong
River and on the integrity of the delta landform. These two reports testify to the importance of integrated planning and assessment
of cumulative impacts before committing to
large-scale developments.

Lessons Learned—Governance,
Hydropower, and Fisheries in the
Mekong
Six lessons can be drawn from the experience
to date with development of dams on the mainstream in the lower Mekong basin. A broader
analysis of integrated management experiences in the Mekong River and Murray–Darling River in Australia (Campbell et al. 2013)
identified additional lessons, several of which
complement those below.
Lesson 1: decisions about resource use can
be unrelated to resource management
Decisions about mega-infrastructure such as
dams are often made at the highest levels of
government, beyond the level of managers of
energy or natural resource agencies and the
planning processes they administer. For instance, the proposed Sambor Dam in Cambodia, to be built by a Chinese developer, appears
to be just one element of a centrally organized
Chinese strategy for investment and political
influence in Cambodia (China’s Cambodian
hegemony 2009). The Don Sahong proposal in
southern Laos was signed off by the provincial
governor long before any consideration was
given to its contribution to the national power
grid or its impact on the fishery, the tourism
amenity of the Khone Falls, or the highly endangered Mekong dolphin population inhabiting the pool below the dam site.
Lesson 2: different public viewpoints and
value judgments by political leaders must be
acknowledged
We are not all on the same page. Different
commentators will variously favor different
perspectives, such as immediate economic
development, electricity supply, overt signs of
development (physical infrastructure), and income to government on the one hand; or livelihoods, community cohesion, long-term food
security, ecosystem functioning, and maintaining biodiversity on the other. Balancing these
different perspectives should be on the basis of
scenario testing backed by good science. However, decisions at national and regional levels
are always value judgments made by political
leaders.
Lesson 3: integrated planning is essential for
rational development of natural resources
The Mekong and its tributaries in Laos provide
numerous sites for hydropower dams. The
Ministry of Energy and Mines lists 17 dams already operational, 13 under construction, and
20 in various stages of planning (Department
of Energy Business, www.poweringprogress.
org). These dams have been planned on the
basis of site suitability and electricity generation potential, with evaluation of environmental impacts happening only after the decision
to proceed with the dam. Obviously a better
approach would be to consider hydropower
requirements concurrently with potential environmental and social impacts, as well as biodiversity considerations. Actually, such a strategic environmental assessment of the lower
Mekong mainstream dams was commissioned
by the MRC in 2009–2010. Two of the recommendations from the report were that decisions on mainstream dams should be deferred
for 10 years and that mainstream dams should
never be used as a test case for proving dam
hydropower technologies (ICEM 2010). These
recommendations have not been implemented.
Lesson 4: decentralization of government
hinders sustainable management of natural
resources
Decentralization of government functions may
be beneficial for local delivery of services such
as health care, policing, roads, and other infrastructure. But decentralization is counterproductive for cohesive, integrated management
of the national estate. This is especially the
case whereby benefits of development accrue
locally but the environmental and social impacts are shared widely or even transferred
elsewhere. In the case of mainstream dams in
Laos, several of the concessions were granted
by provincial authorities, justifiably keen to
bring development to their provinces but unaware of, or unconcerned about, the national
and regional implications of damming a transboundary river. One senior member of the na-
conflicting agendas in the mekong river
tional government, in reflecting on this situation in 2008, lamented, “We have lost control
of planning” (author’s personal observation).
Lesson 5: technical information is
essential for decision making and
assessment of trade-offs
Objective, rigorously derived technical information is essential to support discussion
and decision making on issues that, of necessity, involve trade-offs. The fact that fisheries
have received some consideration in planning
the dams on the Mekong has not been a consequence of the easily perceived size of the
fishery. Rather, it is due to promotion of fisheries considerations by the MRCS, backed by
high-quality scientific reports that have provided quantified evidence on the role of fish
migration in the lower Mekong (e.g., Roberts
and Baird 1995; Poulsen et al. 2002; Baran et
al. 2005), the regional importance of fisheries for food security and livelihoods (Hortle
2007; Orr et al. 2012), and the impact of mainstream dams on life cycles of numerous fish
species and fisheries productivity (Baran and
Myschowoda 2009; Halls and Kshatriya 2009).
While these reports may have stimulated the
developers’ design modifications for fish passage at the Xayaburi and Don Sahong dams, the
information has not influenced the Laos government’s overall planning for the number and
location of mainstream dams.
Lesson 6: dificulties in comparing formal
and informal economies, or monetary and
nonmonetary values, hinder policy
development
Dams are part of the formal economy. Engineers and accountants can estimate costs of
construction, the amount of electricity generated, and the annual returns to developers and
governments from the sale of the electricity.
The estimated income from large hydropower
dams is huge and is obviously attractive for
governments wishing to advance the economic
development of their countries and to secure
energy supplies (see ICEM 2010). Fisheries
in the Mekong are mostly part of the informal
economy. A portion of the catch is not traded
285
but is consumed by the fishers or bartered for
other goods. Fisheries are not formally taxed,
so they do not contribute directly to government income. Further, their importance in
terms of food security, health, and welfare lies
largely with disenfranchised people with little
ability to influence national debate.
The comparison of the relative benefits of
dams and fisheries is obviously fraught. The
discussion would be greatly enhanced if monetary values could be assigned to the informal
economy of the Mekong fisheries and to other
nonmonetary benefits, such as maintaining
biodiversity, preservation of endangered species, and the cultural and societal value of a
free-flowing river.
A Better Future Forfeited
The World Commission on Dams (WCD 2000)
outlined seven strategic priorities for hydropower planning, development, and management based on the recognition of human
rights, the right to development, and the right
to a healthy environment. In brief, these are
gaining public acceptance; comprehensive options assessment; addressing existing dams;
sustaining rivers and livelihoods; recognizing
entitlements and sharing benefits; ensuring
compliance; and sharing (transboundary) rivers for peace, development and security. Elements of these approaches have been partially
and occasionally considered in Laos, most
prominently at Nam Theun 2 Dam (Cruz-del
Rosario 2011), although the outcomes have
been highly contested (Lawrence 2009; Baird
et al. 2015). However, comprehensive options
assessment, or integrated planning, has never
been rigorously undertaken at the national
level. This is unfortunate as the country is traversed by a large mainstream river with many
tributaries arising in mountains, providing numerous sites for dams.
Integrated, consultative planning could
have provided for large-scale hydropower
development and resultant diverse, nationchanging economic and development benefits,
as well as maintenance of community aspirations, the conservation of important biomes,
wild rivers and fisheries, and a free-flowing
barlow
286
transboundary river. In this regard, Laos has
lost the opportunity to be a world leader in
best-practice hydropower development. Nevertheless, economic gains will be realized, and
with continued advocacy for benefit-sharing
and compliance, those gains may partly extend to the communities affected. On the debit
side, the fishery and other ecosystem services
provided by the river will be permanently degraded.

Abstract.—For the past decade, French inland commercial fishers have faced
increasing difficulties in maintaining their fishing and marketing activities for
the fish consumption sector. Lack of political will, combined with short-sighted
political decision making and increasing regulatory constraints, has made it difficult to develop opportunities for inland commercial fishing. A lack of collective
organization among inland fisheries markets, the sector’s poor visibility and image, and conflicts with recreational angling associations have also contributed
to these difficulties. Consequently, some small-scale commercial inland fisheries
are undergoing liquidation. However, this sector has also made important contributions to society by diversifying its activities through environmental services
such as data collection for knowledge and conservation of native fish biodiversity.
Indeed, in most cases, professional inland fishers provide the only data on fish
stocks and the health of continental aquatic ecosystems. Indeed, this information,
knowledge, and associated heritage are part of a cultural legacy that deserves to
be preserved, given that fishing plays an important role in the social and cultural
identity of many fluvial and lakeside territories. Commercial fishers could also
play a significant role in implementing long-term cross-sectoral policies through
their contributions to sustainable hydrosystem management, local gastronomy,
and ecotourism. This paper presents the strategy that was used to try to halt the
general decline of small-scale commercial inland fisheries in France and Europe
and describes why the strategy failed.
Introduction
This paper explores the current situation of
commercial inland fisheries in France and
describes the unsuccessful efforts of the entire profession to curb the rapid decline of its

small-scale businesses, from more than 4,000
fishers in the mid-1970s (Luneau et al. 2003)
to only 400 fishers in early 2015. This decline is
occurring in other European countries as well,
most of which are facing the same issues as
France as a direct result of social transformations that have taken place during this period.
Traditionally, commercial fishing has served as
289
290
boisneau et al.
a complementary activity for small farmers, either for sale or their own consumption.
The collapse of this workforce resulted
in a sharp reduction in fishing activity, which
then transitioned into a separate activity with
strong regulatory constraints that limited the
establishment of new businesses. Using eel
fisheries as an example, this paper challenges
the existing fisheries governance and explains
why changes must be made to save inland commercial fisheries from extinction.
Strengths and Weaknesses
Professional inland fishers are a minority in
Europe, and only Finland and France have
national professional associations. In other
European countries, professional inland fishers are represented either by professional associations that include both sea and inland
fishers or by inland associations for both professional and recreational fishers. This lack of
specific representation weakens the ability of
inland commercial fisheries to influence decision making (Ernst and Young 2011). This
is particularly true in France where conflicts
between recreational fishers and commercial
fishers over fishery resources and fishing areas have emerged (authors’ personal observation).
All inland fisheries share some strengths
stemming from the traditional nature of their
activities. Commercial fishers are the guardians of specific expertise and have developed
empirical knowledge about aquatic ecosystems. Moreover, this knowledge is the legacy
of the transmission of knowledge and savoirfaire from older fishers to new entrants into
the profession (Boisneau and MennessonBoisneau 2001; Ernst and Young 2011). Because of their daily presence on lakes and
rivers, they are keen observers and sentinels
of aquatic habitats. They are often the ones
who quickly alert authorities when there are
problems with fish stocks or ecosystems, unlike government departments that have been
less committed to commercial fishers and anglers since the creation of the French National
Agency for Water and Aquatic Environments
(ONEMA) in 2006 (Thomas Changeux, Institut
de Recherche pour le Développement, personal communication).
Commercial inland fisheries face several
major threats (Allan et al. 2005; Dudgeon et
al. 2006, cited by Suuronen and Bartley 2014;
CNPMEM et al. 2009; FAO 2010, 2012; Ernst
and Young 2011):

The collapse of fish stocks (mostly for diadromous species such as European Eel
Anguilla anguilla L. and Alantic Salmon
Salmo salar L.) and subsequent restrictions on fishing activities;
Water and fish contamination (e.g., polychlorinated biphenyls (PCBs, heavy met
als, and phytosanitary products) and subsequent bans on the sale of fish;
Rapid changes in ecosystems and fish populations following the introduction of invasive species in a context of climate
change (Bates et al. 2008; Barange and
Perry 2009; both cited by Suuronen and
Bartley 2014);
Lack of consistent strategies for fisheries
management and product marketing;
Lack of fishers’ organizations or, where
they do exist, lack of support from authorities;
Limited recognition of these organizations
as advocates for aquatic ecosystems and
resource conservation, mainly because of
overlapping responsibilities among decision-making bodies at different levels (e.g.,
local, basin, national, and European Union
[EU]);
Limited ability to counter the influence of
agroindustrial lobbies and little support
from environmental nongovernment organizations that criticize commercial fishing without fully understanding it; and
In Eastern countries, a drastic decline in
inland fisheries and imbalance between
recreational and commercial fishing after
the collapse of centrally planned economies and the shift to private systems.
The number of commercial fisheries that
depend on migratory species is expected to
keep decreasing in the short to medium term.
Other fisheries could survive, but commercial
fishing opportunities are generally restricted
how to transmit and maintain knowledge in the context of global change
because of a lack of political will all across Europe (Ernst and Young 2011).
Moreover, commercial fishers on the
Loire River have contributed to modeling of
eel migration to the ocean by providing catch
data and explanatory variables over a period
of 20 years (Acou et al. 2009; P. Boisneau, C.
Boisneau, A. Acou, and E. Feunteun, paper
presented at the American Fisheries Society
144th Annual Meeting, 2014). Loire River fishers also participated in EELIAD (European Eels
in the Atlantic: Assessment of Their Decline),
an EU-funded collaborative program investigating the marine migration of the European
Eels, and made it possible to collect the first
data about the downstream migratory behavior of the silver eel and to assess the most important factors influencing its production and
migration success (Aarestrup et al. 2009). Such
fruitful collaborations are unfortunately all too
rare. Professional fishers still have progress to
make, but so do research organizations, fishery management agencies, and decision makers. These groups need to make better use of
fishers as key resource management partners
and establish funding mechanisms for sustaining small-scale fisheries (E. Amilhat and coauthors, paper presented at the 16th JapaneseFrench Oceanography Symposium, 2015).
Indeed, on the Loire River, as paradoxical
as it may seem, maintaining commercial fisheries is essential for the sustainable management
of one of the last wild rivers in Europe and the
fish species it contains. The glass eel restocking
programs, which result from the requirements
designated in an EU eel regulation adopted in
2007, are mainly implemented by commercial
fishers. The objective of this regulation is to
support preexisting stocks and increase silver
eel escapement to the sea, transferring glass
eels caught in estuaries to sites with conditions
deemed favorable to their growth (e.g., optimal
habitat and water quality, high productivity,
and low density) and survival (e.g., reduced
mortality). In France, professional fishers are
involved at the local, regional, and national levels, with the technical and financial coordination and implementation of activities between
different watersheds, including glass eel collection to enhance growth, transport, and re-
291
lease eel fingerlings in receiving catchments
(authors’ personal observation).
Financial and Regulatory
Obstacles
Severe limitations on eel fisheries have accelerated the decline of professional inland fishing.
These limitations include the adoption of a quota system under EU eel regulation to gradually
decrease glass eel fishing capacity and restrict
fishing periods, as well as the banning of fishery
products marketing under a PCBs action plan.
Moreover, government incentives have encouraged fishers to leave the profession (Figure 1),
and the disappearance of the Asian market,
which was a major consumer of French glass
eels, has negatively affected the market demand.
Indeed, the drastic reduction in landing prices
after 2007 has had profound and lasting effects,
particularly in France as France is the leading
European producer of glass eels for consumption (Figure 2). With no financial compensation
mechanisms, about half of French inland commercial fisheries, which directly depend on this
fish resource, disappeared.
The drop in prices has also affected stocking programs, which appear to be economically
unsustainable because European demand does
not actually correspond to initial commitments
made by EU member states that use this management measure, thus influencing the decline
in price. In France, marine and inland professional fishing organizations are taking the
lead in the national eel restocking program to
allow France to reach its objectives. However,
since 2014, inland fishing organizations have
been forced to find private funding for at least
20% of the cost of these programs (and up to
50% depending on the activity) because of a
change in European Commission funding rules
for entities that are not recognized as “bodies
governed by public law” (Journal Officiel de
l’Union Européenne 2014).
In spite of a relatively high co-funding rate
and generally much better access to co-funding
in France, as compared to other EU member
states, this new rule put an end to the already
infrequent projects led by stakeholders other
than commercial fishing organizations, as well

how to transmit and maintain knowledge in the context of global change
as limiting awareness-raising among other potential project leaders: while the EU requires
member states to conduct restocking operations, those planned for the winter of 2014–
2015 were interrupted, and the submission of
new projects for the 2015–2016 season was
prevented. To offset the loss of these stocking
projects, the French Ministry of Ecology was
forced to relaunch a call for proposals because
the goals set by the European Union were not
achieved in some river basins (Ministère de
l’Écologie, du Développement Durable et de
l’Énergie 2015a). The same EU rule now applies to scientific monitoring (Journal Officiel
de l’Union Européenne 2014). Furthermore,
the borrowing costs for these European stocking or scientific monitoring programs are now
no longer eligible for national co-funding: the
interest on bank loans taken out to cover advance payments will no longer be reimbursed
(authors’ personal observation).
In this context, the French professional
organizations must take economic risks to fulfill these government-supervised obligations
without being given the means to comply with
the obligations under satisfactory conditions.
This situation is particularly inequitable given
that restocking projects are temporary mitigation measures to offset eel mortality factors
other than fishing (e.g., intensive farms, heavy
industries) for which other stakeholders are
responsible. Unfortunately, these same stakeholders refuse to recognize their contribution
to the problem and to pay their share. More
generally, professional fishers face strong
obstacles to receiving technical and financial
support for their contribution to scientific
programs (through catches in aquatic habitats
that require specific knowledge and knowhow, such as for European Eel) and other
general interest services. Insufficient returns
on investment with very long payment terms
further weaken the profession. In France, the
number of professional fishers (all target species included) had declined to 400 fishers in
2015. At this time, inland fishers organized
into the National Committee for Professional
Freshwater Fishing (CONAPPED) and reminded the European Commission of the seriousness of the situation both for the profession
293
itself and for inland fishery resources management, in the context of the Common Fisheries Policy reform.
An Unsuccessful Strategy at the
International Level
For about 25 years, French professional fishermen have been warning authorities about the
gradual degradation of aquatic ecosystems. In
the early 2000s, they asked European authorities to establish a restoration plan for the European Eel on a scale that has been never implemented. They also agreed to the inclusion of
this species in Appendix II of CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora), which ensures
strict traceability of commercial movements
within and outside Europe. Professional fishers agreed to these efforts not only to ensure
sound management of endangered fish species
(such as European Eel, Atlantic Salmon, or Allis Shad [also known as Allice Shad] Alosa alosa L.) and their essential habitats, but also to
conserve age-old fishing practices that are an
integral part of the economy and culture in the
European river basins where these species live.
This activism has received little attention from
the European Inland Fisheries Aquaculture Advisory Commission (EIFAAC) of the Food and
Agriculture Organization of the United Nations
(FAO), aside from minor advances. But professional fishers cannot participate in these meetings anymore since 2004 because of huge political and administrative obstacles. Thus, their
knowledge and expertise are not taken into
account.
As far as the International Council for the
Exploration of the Sea (ICES) is concerned,
it recommends reducing all anthropogenic
causes of fish mortality as much as possible.
But, in fact, only mortality due to fishing is
used as an adjustment variable in models,
even if the scientists are unanimous in their
agreement that fishing is not the only factor;
the “as much as possible” is linked only to fishery management while economic and social
aspects are not taken into account. Such a vision stems from the obstinacy of the EU, which
makes decisions based advice from the ICES
294
boisneau et al.
and wants to find an administrative solution to
the resource decline at all costs, even if that response is insufficient. It does not take into account the economic and social benefits of the
fishing profession and the fact that restoration
will not be successful because other mortality
factors are not addressed (authors’ personal
observation).
Faced with these obstacles from European authorities, and after years of successive
French governments refusing to arbitrate between the various freshwater stakeholders, the
National Committee for Professional Freshwater Fishing, in partnership with other organizations in Europe (notably in Sweden, Finland,
and the Netherlands), developed a strategy in
2013 based on two approaches:
•
•
A nonmonetary approach to create an inland fisheries advisory council (similar
to one that exists for maritime issues and
for aquaculture) to bring political visibility to professional inland fishing. The creation of a forum for dialogue to strengthen
the professional sector was viewed as a
mechanism to enhance the position of
commercial fishers and their ability to influence decisions concerning their future.
A monetary approach, within the framework of the new European Maritime and
Fisheries Fund, particularly focused on
financial support for environmental services provided by inland fishers (including
their collaboration with scientific programs) and the development of new commercial activities. An example is the establishment of economic outlets for species that have not increased in value (or
not enough). This is particularly relevant
for some invasive species as French professional fishers face strong political and
legal obstacles in finding innovative ways
of removing the undesirable species or in
creating added value through industrial
processing.
Unfortunately, these two strategies were
unsuccessful. Despite support from the European Parliament’s Committee on Fisheries, the
advisory council proposal was rejected by the
European Parliament. Almost all of the pro-
posed amendments to the new European Maritime and Fisheries Fund were denied.
In the end, apart from a few marginal steps,
the professional freshwater fishing situation
in Europe has not changed with the Common
Fisheries Policy reform and the implementation of the new fund. The authorities only
supported certain investment operations or
sought to mitigate the loss of fisheries through
plans for temporary or permanent cessation of
activity. The only current possibilities (mainly
for European Eel) remain certification and
joint financing for restocking, in spite of recent
difficulties in terms of co-funding rates. Nevertheless, payments for environmental services
are increasingly used in environmental and
development policies, particularly in southern
countries (Bureau 2010). Surprisingly, Europe
still does not make much use of payments for environmental services, with the exception of the
Common Agricultural Policy agri-environmental measures introduced in the 1990s, which
have evolved towards compensation for services rendered (Aznar 2013). As far as certification
is concerned, the fishing profession has begun
to join forces with the Sustainable Eel Group, a
European science and conservation nonprofit
organization that brings together organizations
and individuals involved in eel recovery.
The Profession’s Adaptive
Capacity Has Reached Its Limits
There is no reason that approaches previously
used in agriculture cannot be applied to fisheries, especially inland fisheries. Although they
are under a great deal of pressure from a number of different directions, commercial inland
fishers have adapted to take environmental
issues into account. In France, fishers have
developed considerable environmental understanding and protection skills, though authorities unfortunately do not recognize the value
they provide to other stakeholders and could
provide to aquatic habitat restoration. This expertise includes
•
Fish rescue operations prior to draining of
waterways, canals, stormwater retention
basins, and so forth.
•
•
how to transmit and maintain knowledge in the context of global change
Support for fish management diagnostics
in ponds and balancing of fish populations
in natural aquatic habitats by regulating
overdense or exotic species such as Black
Bullhead Ameiurus melas Rafinesque,
Pumpkinseed Lepomis gibbosus L., exotic
carps of the Cyprinidae family, Wels Catfish Silurus glanis L., spinycheek crayfish
Orconectes limosus Rafinesque, signal
crayfish Pacifastacus leniusculus Dana, and
red swamp crayfish Procambarus clarkii
Girard.
Sampling catches for research purposes, to
study fish population structures, monitor
diadromous fish migrations, perform
health studies, and so forth.
However, professional fishers cannot easily diversify their activities, even though it
would allow them to maintain their skills and
potentially pass them on to a new generation
of fishers, in France or elsewhere in Europe
where they may have already disappeared.
Indeed, they face many political or legal obstacles, including inconsistent public policies,
such as the authorities’ inability to enforce the
French Environmental Code and prevent the
transfer of nonnative species between watersheds, which is tolerated in the case of Wels
Catfish (Copp et al. 2009) but prohibited in the
case of invasive American crayfishes (Basilico
et al. 2013).
In general, most professional freshwater
fishers are fully aware of their responsibilities in the conservation of fishery resources
and suffer the consequences of sector-based
policies that do not respect the management
principles of an ecosystem approach, as defined in a United Nations workshop in Malawi
in 1998 and adopted at the Fifth Meeting of
the Conference of Parties to the Convention
on Biological Diversity in 2000. These policies
hold the fishing profession mainly responsible
for the erosion of continental fish stocks while
ignoring the responsibilities of multiple stakeholders involved in the degradation of aquatic
ecosystems. In spite of the European Water
Framework Directive mandate that all EU water bodies must attain “good ecological status”
by 2015 under criteria defined in Annex V of
295
this directive, 47% currently have “bad ecological status” under these criteria, meaning that
human activities have had strong impacts on
the ecological characteristics of aquatic plants
and animal communities (European Commission 2012). Indeed, the balance of power that
governed the implementation of this directive
resulted in a policy favoring qualitative water
management, excluding key parameters for
ichytofauna (e.g., endocrine disruptors) at the
expense of quantitative management, which
is in fact fundamental, as with the example of
the impact of irrigated agriculture on spawning grounds (Elola Calderón 2010). In addition,
certain biological indicators such as diadromous fish have also been excluded (authors’
personal observation).
Strengthening obsolete restrictions from
an era when fishers were far more numerous
will not bring about solutions to the problem
of fish stock decline and help protect aquatic
ecosystems. There is also a need to shift away
from an approach in which policymakers base
their decisions almost exclusively on recommendations from scientific experts. In many
cases, regular, reliable, and controlled data can
only be provided by commercial fishers, especially in the case of European Eel in waters
deeper than 1.5 m because electrofishing is not
feasible in France due to regulations and technical limits. While other stakeholders do not
comply with or enforce compliance with regulatory obligations to report catch data, the fishing profession would prefer a more participatory approach that sees fishers as much more
than a source of data that is later used against
them. Indeed, the majority of scientific models,
which are solely based on catch data provided
by professional fishers, automatically assume
that the natural mortality rate is constant and
truly natural.
This is evidently not the case for migratory
fish species, as there has been clear ecosystem
damage in the past 50–60 years (Adam et al.
2008). In this context, the more fishers report
to fishery management agencies, the more
trouble they make for themselves because the
real causes of eel decline are not taken into account with the same importance, as it depends
on the stakeholders involved (CONAPPED
296
boisneau et al.
2010). Out of 88,000 obstacles to fish migration in France, 1,555 are in priority eel conservation areas and must be adapted to ensure
free passage of eels, but only 477 structures
were made passable by the end of 2015 (ONEMA, in press). Given this situation and all the
other anthropogenic pressures on this species,
some scientists consider it impossible to estimate anthropogenic mortality separate from
fishing with currently available information
(Ministère de l’Écologie, du Développement
Durable et de l’Énergie 2015b).
The underlying objective of commercial
inland fishers is the preservation of biodiversity, which is necessary for sustainable management for the common good and which will
ensure long-term maintenance of the economic resources. Fishers must no longer be treated
wrongfully as a destructive force that erodes
biodiversity (CNPMEM et al. 2009; Bernard
et al. 2014). For this change to happen, prejudice against professional fishers must end, and
awareness must be raised among scientists and
policy decision makers. This will not be possible without the support of civil society, which
must mobilize around fishers as it already has
for other minorities. How will this change take
place? Perhaps it will change through information campaigns on social media showing examples of the potential cascading effects of commercial fisheries extinction. The example of
the Volga River in Russia is instructive because
commercial fisheries were blamed for the fish
stock decline and thus outlawed. This resulted
in an explosion in poaching and further degradation of these stocks (D. F. Pavlov and Y. V.
Gerasimov, presentation at the Global Conference on Inland Fisheries, 2015). France could
soon face a similar situation for several species such as European Eel (glass eel stage), the
migratory Salmonidae in coastal areas (Brown
Trout [also known as Sea Trout] Salmo trutta
trutta L. and Atlantic Salmon), Northern Pike
Esox lucius L., or Walleye (also known as Pikeperch) Sander lucioperca L. (authors’ personal
observation).
But as long as European authorities ignore the environmental contribution of professional inland fishers and France remains neutral and implicitly supports the most powerful
stakeholders, it will be difficult to create social
change. However, it is up to the community
rather than government authorities to define
how the common good is shared.
The United Nations Context to
Support Small-Scale Fisheries
In 2014, the FAO’s Committee on Fisheries formally endorsed the International Voluntary
Guidelines on Securing Sustainable Small-Scale
Fisheries in the Context of Food Security and
Poverty Eradication (FAO 2015). These guidelines will now have to be implemented. In this
context, they should be relevant for all vulnerable and marginalized groups that depend on
small-scale fisheries. This is the case for European professional inland fisheries.
As the International Collective in Support
of Fish Workers recently outlined, representatives of fish worker organizations from developed countries pointed out that while the
small-scale fisheries guidelines focus on the
south, there are marginalized and vulnerable
groups in the north as well. An exclusive focus
on the south would give industrialized countries an excuse not to implement these guidelines (ICSF 2014).
During the United Nations Conference
of the Parties to the Convention on Biological Diversity, held in Nagoya, Japan in October
2010, a coordinated ecosystem approach was
presented and promoted as a necessary crossfunctional conceptual approach. This ecosystem approach to fisheries (EAF) was evoked in
the FAO’s international guidelines on securing
sustainable small-scale fisheries (FAO 2015).
But in 2016, how is EAF applied to European
aquatic habitat restoration and fishery resource management?
Conclusion
The commercial fishing situation in France has
now reached a critical stage. Some professional
fishers associations, like those on the Loire River, provide the only data the government uses to
assess fish stocks and to estimate the effectiveness of public restoration policies. Professional
fishers in France and elsewhere in Europe made
how to transmit and maintain knowledge in the context of global change
a deliberate choice to contribute their skills to
the protection and restoration of fish fauna
biodiversity. But fishing restrictions for certain
species, as well as chronic obstacles in accessing
funding mechanisms to diversify their activities
(e.g., environmental services that are already
provided at the European level for agriculture),
are gradually leading European professional
inland fisheries and their cultural heritage towards increasing economic insecurity, closure,
or accelerated decline (Ernst and Young 2011).
What price will society pay in terms of
aquatic habitat degradation? How can the gap
be reduced between the ecosystem approach
theory and its application? Lessons from the
past show that it is not the lack of ecological
data, but rather the lack of good governance
that presents the biggest obstacle to EAF implementation (Suuronen and Bartley 2014).
In this context, how can inland commercial
fisheries become involved in such an approach
before it is too late? The causes of the decline of
European fish stocks are multiple and extend
well beyond fishing: the depletion of wetlands,
habitat degradation through the construction
of obstacles to fish migration, environmental
contamination and pollution, turbines, diseases, parasitism, and nonnative and invasive
species. The sum of these disturbances has resulted in substantial deterioration in the quality of essential habitats for fish species (Adam
et al. 2008).
While professional fishers have kept
their promises and collected information, and
planned studies, the inconsistency in water
public policy outcomes, as well as increasingly restrictive administrative procedures,
will gradually drive them into bankruptcy if
nothing is done to reverse the situation. First,
fishers in the Seine, Rhone, Garonne, and Loire
River basins will become bankrupt, followed
by those in other places in France and across
Europe.
Ireland prohibited eel fishing in 2009 and
now has difficulty assessing the effectiveness
of eel conservation measures that were implemented. In 2015, an ongoing scientific study
involving former eel fishers and the reauthorization of commercial fishing activities are seriously being considered (Fishermen knowledge
297
needed for scientific eel study, 2015). What can
be done to prevent this type of situation across
Europe?
This example also shows the need to promote a broader ecosystem approach to better understand the vulnerability of human
communities to global change (i.e. large-scale
changes in Earth’s system and society). How
will inland fishing communities adapt to
these transformations? Is there a strong risk
that their disappearance will accelerate the
anthropization of these very biodiverse hydrosystems, which are already highly degraded? (Bernard et al. 2014).
This raises the question about whether the
role and governance of inland commercial fisheries in Europe should be adjusted, and if so, in
what way? Even if commercial fishers are represented in consultation structures such as water or fishery management commissions, as it
is often the case in France, their points of view
are marginalized because their political weight
is insufficient. Only participatory science and
an extension of governance to citizens, as well
as drastic changes in the managerial behavior of the EU and national fishery authorities,
could cause positive change. The authors of
this paper endorse the following principles
taken from the DIMPAT program (Bernard et
al. 2014):
•
•
•
•
The critical importance of small-scale fisheries has to be taken into account in public
policies for rural development.
The sustainability of fishery production
chains in coastal, estuarine, and inland
habitats must also be associated with a reduced ecological footprint for other uses.
Participatory research programs have to
be initiated and strengthened as soon as
possible to assess the evolution of aquatic
habitats under pressure from global
change.
The diversity of small-scale fisheries is a
tremendous resource. Protecting these
fisheries must be a stated priority for the
foundation of ecologically sustainable development supported by public aid. It
should also be a strong focus area for regional planning.
boisneau et al.
298
•
The diversity of fish production through
out the seasons protects food security and
promotes French culinary culture. These
niche productions need to be protected
and assisted in their ability to innovate.
Fishery management agencies can no longer ignore the traditional knowledge of professional fishers and consult only scientists that
make limited contributions to fishery management. That is what Elinor Ostrom, the Nobel
Prize recipient for economics in 2009, demonstrated through her work on social-ecological
systems. The social aspect is essential because
it refers to the position and involvement of
each stakeholder in the better use of goods and
services provided by ecosystems (Bernard et
al. 2014).

Abstract.—South American large-river fisheries are experiencing a growing pressure due to mining activity, construction of dams, water diversion, dredging, commercial overfishing, pollution, floodplain deterioration, agriculture, and development.
Despite the fact that artisanal fisheries represent a valuable resource for many riverine communities and play a critical role in assuring food security and poverty alleviation, managers are challenged to develop sound governance processes that ensure
the sustainability of resources and fishing communities. The lack of effective governance processes in artisanal fluvial fisheries is rooted in several social, economic, institutional, and ecological/environmental constraints. Most large-river fisheries are
managed under a conventional approach, applying centralized government control
policies that minimize stakeholders’ participation in management decision making.
River-fisheries governance is dependent on institutions, policies, and economic and
political scenarios that are outside the fishery sector. Market demands and construction of dams and river fragmentation, mining, pollution, cattle agriculture, deforestation, and recreational fishing pressure are all factors that have the potential to alter
fisheries sustainability. Governance mechanisms in South American large rivers can
be developed at three levels but need to prioritize economic growth, food security,
employment, equitable access to resources, and poverty alleviation and promote and
integrate the sustainable use of fluvial resources through stakeholders´ involvement
in decision-making processes. To achieve such goals, new institutional and legal arrangements should be promoted envisioning small-scale fisheries as ecosystem services and implementing an ecosystem-based approach that integrates ecological and
human components to support better governance processes.

Introduction
baigún et al.
Management of South American large-river
fisheries is challenging for managers due to
increasing fishing pressure, construction and
operation of dams, water diversion, dredging,
pollution, floodplain deterioration, and agricultural and cattle development (Barletta et al.
2010). River fisheries play a critical role in the
livelihoods of artisanal fishing communities
by providing food security, nutrition, employment, and poverty alleviation (Berkes et al.
2001; Béné et al. 2007). The number of people
employed in the inland fishery sector has increased during the past 50–60 years (Welcomme 2011). In the Amazon basin, for instance, around 100,000 fishers produce gross
revenues of about US$200 million (Almeida et
al. 2001, 2003), contributing 33% of the local
economy (Almeida et al. 2004). However, despite the importance of river fisheries in South
America (Carolsfeld et al. 2003; Barletta et al.
2016), conflicts and related resolving mechanisms have not received proper attention.
Basic governance theory and practice have
grown and received increasing attention during the past decades (Gray 2005; Kooiman et
al. 2005, 2008; Bavinck et al. 2013), but these
have been barely applied to South American
river fisheries. Although fishery agreements
and comanagement initiatives have been successfully implemented in several areas of the
Amazon basin (Almeida et al. 2000, 2001), governance and its application to address fishers´
demands and interests and fish conservation
still remain poorly developed for most of South
American large rivers.
This study reviews some of the main issues
faced by artisanal fisheries in South American
large rivers, highlighting those factors that hinder
the ability to enable more effective governance
processes and also discussing the needs and opportunities for governance improvements.
Main Factors Affecting Fisheries
Governance in South American
Fluvial Systems
Large-river fisheries of South America are all
small-scale and considered multifaceted socio-
ecological systems (Berkes et al. 2001). They
involve diverse full- and part-time fishers,
middlemen, transporters, local markets and
processors, retailers, and management agencies. All these sectors are connected through
variable spatial and temporal relationships that
are modified according to fishing trends regulated in turn by the hydrological regime. South
American fisheries are almost all based on
open-access management policies and mostly
supported by lateral and long-distance migratory species.
The Amazon basin is by far South America’s most developed fishery in terms of harvest and target-species diversity (Ruffino
2004; Barletta et al. 2016). These fisheries
provide well-being and mobilize local market
economies, representing a valuable resource
for many riverine communities (Bartley et
al. 2016) and also for rural people inhabiting
surrounding forest landscapes (Coomes et al.
2010). Riverine fishers often use economic
strategies that combine fishing with farming
and cattle ranching, particularly in those large
rivers with alternating dry and wet phases.
River fisheries governance depends on institutions, policies, economic and political scenarios, and patterns of decision making that
often are outside the fishery sector (Jentoft
2007; Mahon et al. 2008). Such problems exhibit the difficulties to put in practice effective
governance process at local, regional, and basin
scales. Lack of effective governance processes
in artisanal fluvial fisheries is rooted in several
barriers such as deficient or null statistical information, fisheries managed and enforced only
at stock levels, and lack of policy responses despite signs of overfishing in several basins (Bayley and Petrere 1989; Tello and Bayley 2001;
Agostinho et al. 2007; Galvis and Mojica 2007;
Rodríguez et al. 2007; Baigún et al. 2013). Also,
increasing recreational fisheries in the major
developed areas of the upper Paraguay, the Orinoco, the San Francisco and the Paraná rivers
has led to stakeholder conflicts that impact artisanal fisheries (Carolsfeld et al. 2003; Freire et
al. 2016). This conflict is worsened when migratory fish species need to be managed under different legal frameworks across basins (ValboJørgensen et al. 2008).
fisheries governance in the 21st century
There is an institutional mismatch between the size of the fisheries and the capacity
for surveillance, enforcement, and acquisition
of harvest data, coupled with the absence of
adequate management plans. The high dispersion of fisheries and open-access characteristics in most basins represents a major obstacle
for assessment and regulations enforcement,
particularly when the regulations are neither
agreed nor accepted by fishers. Centralized
government control policies with limited stakeholder’s engagement (Barletta et al. 2010)
have limited fishers´ participation, which is
only an instructive or consultative relationship according to the continuum proposed by
Sen and Nielsen (1996). Fishers´ participation
and their knowledge have been historically
rejected or ignored (Baigún 2015), even denying fishers the legitimate right to participate in
management decisions. This problem has been
exacerbated in those fisheries mostly exploited
by indigenous people. Also, most fisheries exhibit outdated or incomplete legal frameworks
focused on only fisheries issues. The main socioeconomic barriers relate to the underestimation of recreational fisheries impacts, weak
inclusion of fishers in formal economic circuits,
poverty and social marginalization of fishers,
and poor economic profits and inequality in
marketing chains. As inland fisheries lack economic visibility and remain poorly valuated,
their local relevance has not been properly
addressed (Benetti and Thorpe 2008). At the
ecological and environmental level, landscape
and waterscape degradation mainly produced
by deforestation, construction of dams, and agriculture are all factors having the potential to
alter fisheries sustainability and therefore to
promote governance conflicts.
What Governance Should Mean
in South American Large-River
Systems
Governance priorities in large rivers should address the body of rules, traditions, norms, social
networks, and regulations that allow key stakeholder involvement, participation, and interaction in the decision-making and implementation process. Ultimately, fisheries governance
303
needs to assure economic growth, food security,
employment, equitable access to resources, and
poverty alleviation and to promote and integrate the sustainable use of fluvial resources
and fishery resilience mechanisms.
According to Kooiman et al. (2005), governance could be envisioned as three interactive level processes that can be well identified and adapted to large-river fisheries.
First-order governance relates to solving daily
local conflicts and societal problems, which in
fluvial systems involve making decisions about
fishing areas, fishing satisfaction, conflicts between recreational and artisanal fishers, landing sites, market chains, and access and rules
enforcement. Second-level governance corresponds to institutions and organizations that
provide the framework within which first-order governance takes place by framing norms,
laws, and agreements; solving problems; and
creating opportunities. In South American
large rivers, this level is often filled by government offices or institutions that lack the
required expertise and are not well suited to
accomplish this task. Moreover, fishers´ organizations are scarce and poorly developed. The
third order or metagovernance is about the
constitutive values, norms, and principles upon
which governing activities and institutions
are founded. Metagovernance reflects norms,
ideas, and principles to improve governance at
the first- and second-order levels and can also
promote new directions and goals. At this level, fisheries governors need to make explicit
their ideas and initiatives for discussion and
evaluation and decide how, in practical terms,
the ideas should inform collective decisionmaking and managing practices (Bavinck et
al. 2005). This level is usually weak in fluvial
fisheries, particularly when top-down conventional management is, in practice, lacking
strong stakeholders’ involvement and public.
All these governance orders, however, should
integrate a multiple-scale perspective. At the
local scale, for instance, fishery systems are
shaped by internal components and external
stressors, but as the spatial scale increases,
a broader array of actors, institutions, and
stressors acting along the basin influence and
increase governance complexity.
304
baigún et al.
Good governance examples, however, are
found in the Amazon basin where fishing agreements nested in comanagement were installed
to limit commercial exploitation and to protect
subsistence-oriented local fishers (Almeida et
al. 2001, 2009; Silvano et al. 2009). As a result,
overfishing trends were reduced, fish yields
were increased, and stakeholder conflicts were
minimized. Active fishers´ participation helped
in recovering the iconic Paiche (also known as
Arapaima) Arapaima gigas fishery (Castello et
al. 2009). In the upper basin in Peru, territorial use rights for fisheries (TURFs), coupled
with comanagement and community-based
management, were successfully applied to
protect main target species and, ultimately, local fishers’ livelihoods (Anderson et al. 2009).
Such cases demonstrate the critical relevance
of strengthened local capacities based on incorporating traditional ecological knowledge,
promoting rights of access to the resources,
and protecting critical habitats for fish life cycles. Improvement of control and surveillance
provided fishers with a general awareness of
ecological and resource management concepts
under a comanagement regime (Castello et al.
2009; A. Oliveira and L. Cunha, paper presented at the 8th biennial conference of the International Association for the Study of Common
Property, 2000).
The Need for Adopting an
Ecosystem-Based Governance
Perspective
As large-river fisheries are strongly embedded within a watershed, including man-made
and natural processes, governance should be
visualized at multiple dimensions and scales,
considering ecosystem and social factors as
main interacting drivers. Preserving ecosystem health in large rivers emerges as one of
the most critical outcomes of the governance
processes for supporting long-term livelihoods
and welfare conditions and maintaining the
capacity to cope with external stressors from
outside the fishery sector (Pasqual-Fernandez
and Chuenpagdee 2013). In this context, the
three-level governance systems should retain
the ecological integrity of fluvial systems as
the main basis for providing goods and services for a diverse spectrum of stakeholders and
riverine communities. In the Amazon and the
Orinoco basins, for example, interactions between people and the natural environmental
vary spatially and temporally, usually involving complex governance processes (McGrath
et al. 2008), and agriculture plays an important role during the dry season. Expansion of
agriculture, however, could affect the forests
as critical habitats for many valuable fish during the flooding season (McGrath et al. 2008).
In the Magdalena River, floodplains occupation
by ranchers have reduced fishing areas (Junk
2007), whereas in the lower Parana River, inner lagoons that are important rearing and
fishing habitats have been isolated and converted to agriculture and cattle areas (Baigún
et al. 2008).
River fragmentation by dams is probably
the most pervasive factor that disrupts fluvial
ecological integrity and affects fluvial fisheries. In the upper Parana basin, reservoir formation has reduced fish yield and decreased
stocks of large migratory species having high
commercial and sporting value, thus impacting
fishers´ socioeconomic conditions (Agostinho
et al. 2003; Hoeinghaus et al. 2009). Similar
patterns were noted in the San Francisco River
(Sato and Godinho 2003). The loss of ecosystem health in fluvial systems could have direct
impact on rural fisheries where fishing strongly contributes to food security. The deterioration of human, natural, financial, social, and
human capital as part of livelihood assets could
compromise the resilience of communities to
cope with severe or irreversible impacts. The
above examples point out the need to balance
cost and benefits for different stakeholders in
large rivers, integrating man-made infrastructure with fishers’ needs, demands, and rights
as part of main governance outcomes.
Ecosystem-based governance in fluvial
systems should be strongly related to the application of an ecosystem-based approach for
fisheries management (EAF). The EAF recognizes the human component as one of the
main pillars for governance (De Young et al.
2008), giving stakeholders´ participation a
central role. An ecosystem approach oriented
fisheries governance in the 21st century
to fisheries thus provides a powerful framework to assess and recognize main gaps and
limitations in solving social, economic, fishery,
environmental, and institutional problems
that shape fishery governance. In addition, it
requires and promotes the interaction across
different sectors that use and could impact
water resources. Unfortunately, the EAF concept is still poorly developed in South American large rivers and is not being yet considered by management agencies as a desirable
goal to achieve better governance (Barletta et
al. 2016).
Conclusions and Future
Directions
Installing better governance processes in South
American large rivers is challenging managers
and other main stakeholders. Suitable governance practices in South American rivers have
not yet been underpinned by the application
of strong social, economic, institutional, and
environmental criteria and practices. Poor
governance results can be attributed to visible problems associated with increasing basin
fragmentation, pollution, and overfishing, but
social, economic, and institutional problems
have remained less detectable or even not well
perceived by government and other stakeholders. The importance of the social dimension
for small-scale fisheries governance cannot be
emphasized enough (Arthur et al. 2016). Most
tropical small-scale fishers are comprised of
poor and marginalized people (Pauly 1997),
and in several South American basins, large
populations suffer from inadequate nutrition
and exclusion of their lands and lack the most
basic health services, social rights, and education (Chapman 2008). Exclusion of the people
that depend on fisheries from political decisions weakens the governance process (Friend
2009) and reduces collective efforts to participate in sustainable resource management
(Ratner and Allison 2012). Management approaches that are centrally controlled with little or no stakeholder involvement still remain
a main obstacle to improving the governance
processes by reducing the possibility of sharing responsibilities and decisions with man-
305
agement agencies. This is due to their inability
to cope with the complexity of fluvial fisheries,
which are driven by environmental features,
the interaction with fishing activity, and the
lack of support from the people dependent on
the fishery.
Accelerated development of artisanal
fisheries in South American rivers, increasing man-made impacts, and climate change
all could impact rivers’ ecological integrity
and necessitate improving governance conditions in river fisheries. Moving to an ecosystem-based perspective to promote better
governance processes, however, will require a
long effort in recognizing different stakeholders’ visions and problems as the basis to start
discussing actions and potential solutions for
new governance paradigms (Chuenpagdee
and Jentoft 2013). Several general measures
inherent to small-scale fisheries can be applied to reduce governance barriers in South
American floodplain river fisheries (Table 1).
For example, envisioning fluvial fisheries as
providing highly valuable ecosystem services
and not as commodities and understanding
their irreplaceable social benefits represent
a seminal concept to improve fisheries governance and maintain feedbacks between
fisheries, ecosystem productivity, and aquatic biodiversity (Beard et al. 2011). In turn,
comanagement concepts and participative
management policies need to be considered
as a critical part for improving an ecosystembased governance approach. However, rural
fisher communities still have difficulties in
self-organization and achieving collective actions, which are strong limitations to their
participation in governance processes (Béné
2008). In this context, management agencies need to stimulate consensus, collective
action, and recognition of fishers´ rights and
demands. Clearly, new institutional and legal
arrangements involving experts in planning,
adaptive management, and social skills are
needed to foster not only stakeholder participation in policy making, but also addressing
learning, inclusiveness, and partnership as
part of new interactive management agendas
(Bavinck et al. 2005). Recognition of users´
tenure and rights-based approaches and co-

Measures
Develop reliable fishery information systems to aquire basic data.
Identify indicators of fishery sustainability and related reference point system based
on scientific and fishers’ ecological knowledge.
Develop and apply a community-based approach expanding benefits at social and
environmental levels.
Develop management agreements for common regulations, research, and
monitoring programs for main target species in transboundary basins.
Develop an ecosystem approach to fisheries management to promote fishery,
environmental and social sustainability.
Envision large-river fisheries as a long-term valuable ecosystem service strongly
dependent on fluvial ecological integrity.
Aquisition of informatimon oriented to capture social and economic trends.
Develop appropriate mechanisms for partnership, empowerment, and inclusion of
stakeholders in management plans.
Work with governmental and nongovernmental institutions to improve social and
economic conditions and recognition of fishers’ rights.
Develop and promote fishers´ organizations to achieve better and fairer trade
conditions.
Promote capacity building and training and reinforce management agencies.
Promote stakeholders’ participation, consultation, and comanagement practices for
the formulation and implementation of fisheries management plans.
Develop participative and adaptive management plans integrating the needs,
interests, and demands of a broad spectrum of stakeholders related to fisheries
sustainability.
Promote a sound revision and update of legal frameworks stimulating the inclusion
of norms associated to an ecosystem-based approach.
Develop appropriate management policies to account for different fishing activities
of the most highly vulnerable fishers groups.
Integrate fisheries in multipurpose land and water use management and raise
awareness about fluvial ecological processes and factors that govern fish
production and biodiversity conservation.
Develop research programs oriented to identify and preserves critical migratory
corridors, spawning and rearing habitats that require specific management, and
conservation measures.
Preserve functional processes based on flood high-low water pulses and related to
floodplains and channels connectivity as key factors to support fisheries
sustainability.
management and empowerment of the poor
and more vulnerable stakeholders will also
play a critical role in promoting new governance scenarios (Franz et al. 2016). How new
institutional, legal, and socioeconomic frameworks can be accommodated to shape better
processes based on considering environmental and social sustainability will be main goals
and challenges for future scenarios in large
South American river basins.

Recreational Fishing and Territorial Management
in Indigenous Amazonia

Abstract.—At least 73% of Brazilian indigenous lands suffer one or more pressures or territorial threats, and 55% of federal conservation units do not have approved management plans. These protected areas encompass more than 40% of the
Brazilian Amazonia. Official governmental management programs are not adequately supported and lack consistent monitoring and surveillance. Protected areas are
under immense pressure from mining and commercial fishing and, more recently,
from recreational fishing tourism. Even though recreational fishing in these areas
is legally possible, it has been initiated without due consultation with the affected
communities, disregarding the International Labor Organization’s Indigenous and
Tribal Peoples Convention (No. 169). Also, recreational fishing is being undertaken
in a competitive model with no assessments of feasibility or assurance of socioenvironmental benefits. The community-based project of recreational fishing tourism
implemented in the Marié River resulted from an cross-sectoral partnership supported by government and nongovernmental organizations based on the indigenous
communities’ interest to develop an economic activity to ensure quality of life. The
partnership also developed a joint monitoring and management program to protect
the livelihoods and collective interests of indigenous peoples with emphasis on food
security. The recreational fishing tourism in the Marié River became an opportunity
for the indigenous communities to lead the governance, management, and conservation of their traditional territory.
Introduction
At approximately 710,000 km2, the Negro River basin is the largest basin of black water in
the world. The peculiar color is due to a specific geochemistry and low levels of sediments,
nutrients, and pH. These features result in a
river of low biomass with very high species diversity, with more than 450 fish species identified of which 40 species are endemic (ISA
2009). Characterized by a wide variety of upland and floodplain forest landscapes (Goulding et al. 1988), the basin has been managed
by traditional systems of use, according to the
indigenous knowledge of the people who have

inhabited the region for more than 3,000 years
(Cabalzar and Ricardo 1998). The basin is one
of the most conserved in Amazonia, with less
than 1% deforestation due to several factors
related to environmental characteristics, a history of traditional occupation of low impact,
and, more recently, the recognition of protected
areas (PAs) for 62% of its length (Raisg 2015)1.
Protected areas are localities with relevant socioenvironmental importance and, therefore,
are supported by a specific legal statute relative to their management and use. These areas
are created under the principle of conservation
and tenure rights regarding sustainable use or
full protection (Federal Law No. 9,985/2000,

which established the National Program for
the Conservation Units).
The deforestation rates in Amazonia have
been estimated, and it was confirmed that the
indigenous lands are the most conserved areas
(Fonseca et al. 2015). These results reinforce
the studies that indicate the fundamental role
of the indigenous peoples at preserving the
forests and biodiversity therein, both by traditional management and through surveillance
by living in their territories (Toledo and Barerra-Bassols 2008).
The complex of indigenous lands and conservation units in the upper portion of the basin and the establishment of a mosaic of PAs in
the lower region has helped conserve the natural resources. However, in a large portion of
the middle Negro River region, the land’s rights
are yet to be defined, which exposes this region
to greater fishing pressure. Indeed, the whitewater tributaries (nutrient-rich soil and high
biomass) and the large number of lakes in this
region generate important fish reproduction
Figure 1.—Middle Negro River region.
and nursery sites. This middle Negro River region (Figure 1) is the primary source of fish in
the basin (Amaral 2010), and it is also considered the most important area for recreational
fishing in the Brazilian administrative state of
Amazonas (Batista 2001; Menezes 2005).
The lack of planning or regulation of commercial and recreational fishing activities allows overlap and increases conflicts over resource access (Begossi 2004; Sobreiro 2007).
Although recreational fishing generates employment, the revenue is concentrated with
nonlocal or even foreign agencies that ignore
their socioenvironmental responsibilities. Yet
the region receives an increasing number of
recreational fishing tourists (Zeinad 2003;
Lopes 2010; Barra and Dias 2013). Despite the
lack of systematic monitoring and data collection, the impacts of recreational fishing are a
major concern regarding conservation (Cooke
and Cowx 2004; FAO 2012).
The Socioenvironmental Institute (ISA)
has engaged with local stakeholders to build
recreational fishing and territorial management in indigenous amazonia
cross-sectoral forums among government
agencies, indigenous communities, and fishing
sectors to develop fishery management proposals. Participatory surveys and workshops
were promoted to develop recommendations
for zoning areas and regulating fishing activities (Alves et al. 2012). Despite the State of Amazonas’ governmental responsibility to ensure
sustainable fisheries, none of the public policies or managing measures was implemented.
Both recreational and small-scale commercial
fisheries occur haphazardly, without fish stock
assessments, monitoring, or surveillance.
The pressure on fish stocks has reduced the
availability of resources and stimulated the advancement of recreational fishing in other preserved and protected areas, such as the Marié
River, indigenous land in the transition zones
between the middle and upper Negro River. The
recreational fishing tourism in the Marié River
started illegally through negotiations and cash
payments to some indigenous leaders, dragging communities into the competition between
tourism companies over exclusivity of the fishing area (Barra and Crepaldi 2014).
Despite conflicts, the Marié River provided
an opportunity to set an innovative model of
inland fisheries management once land rights
were defined. Fishery management in the Marié
River was developed under a community-based
project of recreational fishing tourism.
Based on this case study, this paper discusses recreational fishing tourism on indigenous lands and traditional territories as an
example of low-impact activities that might
provide an opportunity for long-term monitoring and management of PAs, with emphasis on
food security and livelihood assurance.
Indigenous Lands’ Legislation and
Challenges for Management
The Brazilian federal government has the tenure rights of the indigenous lands, but the indigenous peoples are entitled to the permanent
holding of the land and the exclusive use of the
assets derived from soil, rivers, and lakes within
these territories (Constitution of the Federative Republic of 1988, articles 231 and 232). It
is the Brazilian government’s responsibility to
313
enhance local culture, traditions, organizations,
and livelihoods, and to support initiatives headed by the indigenous peoples to promote the
well-being of their communities.
The National Policy for Environmental
and Territorial Management of the Indigenous
Lands (PNGATI; Brazil 2012) regulates the insertion of economic activities and tourism in
indigenous lands if these activities contribute to
the territory administration and to the sustainability of families, provided that (1) they are of
collective interest, (2) they are environmentally
safe, and (3) the livelihoods and cultural traditions are respected. The PNGATI recognizes the
right of the indigenous communities to promote
economic activities and establish partnerships,
settling previous doubts that stemmed from the
Federal Constitution and the Statute for Indigenous People (Federal Law No. 6,001/1973).
As of June 2015, a federal normative for
tourism on indigenous lands (FUNAI Normative
No. 3 of 2015) was approved for the the development of activities according to a communitybased model and after performing the required
socioenvironmental impact studies. The indigenous communities are autonomous and will
define the activities that are permitted in their
traditional territory. The Federal Indian Affairs
Agency (Fundação Nacional do Índio; FUNAI)
and other government agencies are in place for
supporting, instigating, and following the activities to assure socioenvironmental security and
the respect of collective and tenure rights.
According to the recent legislation, recreational fishing tourism, although legal, may be
implemented only if it aligns with the interests
of indigenous communities and is preceded by
research that studies the potential impacts of
fishing.
The government is responsible for the management and support of traditional and indigenous communities to assure sustainable use of
the PAs. These correspond to more than 40%
of the Brazilian Amazonia. However, it costs approximately US$200,000 annually to manage a
PA in Amazonia2. The official management pro-

grams are not adequately supported. At least
73% of Brazilian indigenous lands suffer from
some kind of pressure or territorial threat
while 55% of federal conservation units do
not have approved management plans (Raisg
2012).
Considering that natural resource conservation is not a priority for the Brazilian government, tourism provides an opportunity to
generate income to invest in natural resources
monitoring, indigenous land management,
and surveillance and to be used for improving communities’ infrastructure. In this sense,
economic activities of low impact and high
aggregate value, such as recreational fishing
tourism, may contribute to the conservation of
these areas.
The Marié River Experience
The Marié River is an important traditional usage area comprised of 15 indigenous communities and more than 250 families that value
food security, cultural traditions, and stable
livelihoods. The area is also central for economic activities such as small-scale commercial fishing (Barra and Crepaldi 2014).
The diet of the Negro River peoples is
based on fish, as a main source of protein, and
manioc, a tuber (Begossi 2004). The traditional knowledge responsible for management of
fishing resources was deeply affected by colonial occupation since the 18th century, forcing
migration to support the rubber trade (Cabalzar and Ricardo 1998). Fish shortages increased when high-impact fishing gears were
introduced, along with increased commercial
fishing pressure and illegal natural resourceuse activities like mining.
To assure that the rights of indigenous
peoples were recognized and to deal with the
new required dynamics, indigenous communities created nongovernmental representative organizations in the 1980s and 1990s.
These associations operated similarly to a
parliamentary system that brought leaders
together to discuss and make decisions for
the collective well-being. The first indigenous
organization created in the Negro River basin
was the Association of Indigenous Communi-
ties of the Lower Rio Negro, which represents
the communities that traditionally use the
Marié River.
However, the lack of public policies and
basic human rights, such as health and education, and the absence of management and conservation programs allow external pressure
over indigenous communities and the natural
resources. In the search for a better quality of
life, the indigenous leaders are pushed to negotiate with external stakeholders without any
guarantee of sustainability of the proposed
economic activities, often resulting in restricted or individual benefits. It is in this context
that recreational fishing was initiated in the
Marié River in 2010.
Providing excellent recreational fishing3,
the Marié River was invaded by companies
that operated without any socioenvironmental
management plans. These companies signed illegal and simultaneous contracts with multiple
indigenous leaders in search of exclusivity of
the fishing area. Conflicts emerged among the
indigenous communities and the situation was
denounced to the Federal Prosecution Service
(Ministério Público Federal; MPF).
In 2013, after a successful coordinated
effort by FUNAI and the Brazilian Army, the
recreational fishing companies were removed
from the indigenous land. Subsequently, MPF
published a recommendation to prohibit any
recreational fishing activity in Marié River
until FUNAI and the Brazilian Institute of Environment and Renewable Natural Resources
(IBAMA, Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis)
performed socioenvironmental impact studies that evaluated the viability of the activity.
This judicial action was crucial to the regulation process once the government agencies do
not have the necessary financial and human
resources to promote management in Amazonia (Barra and Crepaldi 2014).
At this point, an intersectorial strategy
involving indigenous organizations, their part-

as Speckled Pavon) Cichla temensis was caught in
the Marié River.

recreational fishing and territorial management in indigenous amazonia
ners, and government agencies was initiated to
promote fisheries and regulate the recreational fishing tourism. The Marié River’s indigenous communities assembled and evaluated
the suitability and feasibility of recreational
fishing as an economic alternative for their
sustainability.
The Federal Indian Affairs Agency established technical cooperation with IBAMA and
ISA to work with the indigenous organizations
and communities to regulate the recreational
fishing, observing four ongoing steps:
•
•
•
•
Consultancy: broad consulting to understand and support communities’ interest
to permit recreational fishing tourism (or
any other economic alternative) in their
territory, assuring active and collective
participation in the decision making.
Socioenvironmental studies: assessment
of fish stocks and evaluation of the suitability and feasibility of recreational fishing under an integrated management plan
of the indigenous lands, carried out by
communities and according to their livelihoods.
Monitoring and evaluation: implementation of continuous and participatory monitoring programs of the activity for adjustments during the entire process.
Intersectorial cooperation: technical cooperation and commitments established
among communities, government agencies, and other partners to promote a community-based project.
The results confirmed the high potential for
recreational fishing and fisheries interaction to
respect and to preserve the indigenous livelihoods (Barra and Crepaldi 2014). The process
of consultancy and associated workshops were
important steps to improve communities’ governance over their traditional territory, especially considering (1) the fishing management
plan identified the areas and rules for the different fishing activities with emphasis on cultural
traditions, food security, and conservation; and
(2) the protocols defined to assure all decisions
were made according to collective interests.
Previous studies of tourism activities on
indigenous lands have identified that any ini-
315
tiative should be a component of an integrated
management plan that ensures community
benefits and respects livelihoods (Silva 2008;
Irving 2010). In spite of the complexity of promoting intercommunity agreements, the external threats and pressure over resources might
be transformed into an incentive to meet and
discuss proposals.
The sociocultural perspective encompasses the socioeconomical dynamics of fishing
and how recreational fishing would impact it.
In this sense, during broad community meetings and family surveys, the elements of the
fisheries management plan were discussed
to strengthen customary rules, to incorporate
new elements for managing recreational fishing tourism, and to ensure that the plan was a
feasible economic alternative for collective development (Barra and Crepaldi 2014).
A term of reference with all required criteria was formulated by the indigenous communities and their organizations with technical
support to call for proposals from operators interested in conducting tourism in partnership.
The innovative project started in 2014 with a
community-enterprise contract that contemplates and finances
•
•
•
•
collective investments in the communities,
and a hiring and capacity-building program of local labor;
maintenance of a comanagement program
that involves the monitoring of the fishing
activities and surveillance of the territory;
restricted scale for a low-impact operation
(i.e., fly-fishing catch and release); and
annual evaluation expeditions accompa
nied by appropriate government agencies.
The community-based project of recreational fishing tourism in the Marié River
improved indigenous governance over their
territory because the activity promoted surveillance and fisheries monitoring under the
management plan implemented by the indigenous organization. After 2 years of the project, fish stocks are recovering, as reported by
the indigenous leaders. Also, environmental
balance is confirmed by IBAMA (Crepaldi and
Machado 2014, 2016). From the social perspective, communities are improving their
barra
316
collective infrastructure and a few indigenous
families that previously moved into urban areas looking for a better quality of life have returned to their communities.
Final Considerations
Clear territorial rights are crucial for participatory fishing management and to promote
agreements when conflicts arise. Also, engaging indigenous and traditional people in fish
monitoring programs promotes continuous
data collection, which otherwise would be impracticable in Amazonia. In this sense, recognized PAs are strategic for conservation.
The Marié River case study highlights the
importance of participatory processes that actively involve stakeholders so that the commitments and responsibilities are shared from the
beginning. This is not enough to avoid issues or
difficulties as indigenous communities adapt
socially and economically for tourism. Therefore, it will ensure that the challenges are identified and measured, regarding the adequate
time for each stage of the process to achieve
the conditions for effective comanagement under all perspectives.
Once the assessment studies are performed and the indigenous communities understand all aspects of recreational fishing
tourism, it is necessary to develop programs
for monitoring and comanagement. Despite a
possible partnership with government agencies, these programs must be adequately
funded and independent from governmental
programs, which are restrictive and highly sensitive to the political context.
Sustainable economic activities must promote (1) the interest and continuous participation of the indigenous communities during
the whole process, (2) the involvement of governmental agencies, (3) the necessary studies
to assure the socioenvironmental feasibility
of the activity, and (4) the development of
the activities as part of the integrated management plan of the territory, which includes
monitoring and surveillance measures. To
ensure those aspects are incorporated, specific mechanisms should be developed by
the stakeholders that respect livelihoods and
proper social organization frameworks of the
indigenous communities.
Strategic initiatives that promote traditional livelihoods and economic prosperity
under communities’ governance structures are
promising for long-term monitoring and management of PAs (Barra and Crepaldi 2014). In
this sense, recreational fishing communitybased tourism may contribute to fish stocks’
conservation, thus ensuring food security and
the sustainability of indigenous communities
in Amazonia.

Abstract.—Pampangan District is a floodplain area, containing 21 distinct
swamps characterized by seasonal shifts in the aquatic and terrestrial environment. During the wet season, the floodplain is covered by water with a depth of
1–4 m, whereas during dry season it becomes dry land. Local people living around
the swamps have seasonal activities as fishers during the wet season and as rice
farmers during the dry season. The average gross income is 15,041,000 Indonesian
rupiahs (Rp) per wet season from fisheries and Rp 10,445,000 per dry season from
rice farming. The swamps in Pampangan District are managed in an integrated manner based on local regulations. During the wet season, the water bodies are managed as common property resources, wherein all community members are allowed
to exploit fish resources. During the dry season, the landowners claim their plots of
rice field to cultivate rice. However, some small pools within the rice field areas are
inhabited by several species of fish that are kept as broodstock to supply young fish
for the next wet season.
Introduction
Indonesian inland waters cover around 54
million ha, of which 12 million ha consist of
rivers and floodplains, 39 million ha consist
of swamps, and 2 million ha consist of lakes
and other water bodies. These water bodies
support the livelihoods of poor, rural people.
One floodplain area, the Pampangan District
(Anonymous 2005), is characterized by seasonal shifts between aquatic and terrestrial
environments. During the wet season, the
floodplain is covered by water to a depth of
1–4 m, whereas during the dry season, it becomes dry land. Local people living around
the swamps have seasonal activities as fish-

ers during the wet season and as rice farmers
during the dry season.
Muthmainnah (2013) shows that fishing
plays a major role in the social and economic
development of the rural poor because it is
an important occupation for a large number
of rural people living in the floodplain of the
Pampangan District. In the dry season, people prepare the floodplain and plant rice by
transplanting seedlings, which are raised in a
nursery. When the water level of the Komering River rises and overflows its banks, the rice
fields become flooded and eventually rice may
be harvested from a canoe. The deepest part of
swamp in the rice field is called lebung (pool)
and is permanently flooded, either as a natural
or man-made pool.

Pools usually function as fish habitat during the dry season and are utilized as traps
where fish are concentrated and easily caught
by fishers. Pools have high biodiversity: black
fish species (those living in swamps) include
snakeheads Channa spp., Bronze Featherback
Notopterus notopterus, Climbing Perch Anabas
testudineus, and gourami Trichogaster spp.;
some species of riverine (white) fish are also
found in pools, such as Puntius spp. and Osteochilus spp.
In the Pampangan District, a specific local
regulation states that during the dry season
fishers can catch fish in pools only of marketable size, whereas small fish must be released
to the surrounding swamp waters. Some pools
are also protected as small fishery reserves.
Thus, the pools provide key habitats that
provide food to local communities. However,
water must be managed appropriately among
all users. The conflict between inland fishers
and other sectors can be minimized if there
is communication among stakeholders about
their plan for water utilization. This communication will also improve the access to reliable fish and rice harvest data, thus enhancing
monitoring and conservation programs.
This research focused on how integrated
management in swamp utilization can promote the sustainability of fish resources in the
Pampangan District, South Sumatra Province,
Indonesia.
Methods
Field research was carried out by direct observation on swamp areas and interviews with
fishers, rice farmers, and social leaders from
January to December 2012 in Pampangan District, Ogan Komering Ilir Regency, South Sumatra Province, Indonesia (Figure 1).
The quantitative data collected included
fish catch per unit swamp (kg), fish price (Indonesian rupiah [Rp]), rice field area (ha), rice
production (metric ton/ha), and rice price
(Rp). Data were collected through questionnaires filled in by randomly selected respondents consisting of 102 fishers and 57 rice
farmers. Additional information was also collected from local government officials.
Results
Water-level recordings showed that during the rainy season (December to May), the
swamp water depths are higher than 1 m and
almost all swamp areas are inundated, but
during the dry season (May to November),
the water level decreased to less than 50 cm
(Figure 2). Rice farmers begin to cultivate the
paddy fields in May, and seedlings are moved
into the paddy field in June. The paddy harvest is done in November, when the water
level rises and when there is no more paddy
cultivation.
In Pampangan District, among those interviewed, 57 people worked as rice farmers
and 102 people worked as fishers. Some of
these interviewees alternated between farming and fishing, but some fishers did not have
land for rice cultivation so only fished. Commonly, the fishers work in groups to exploit
fish resources in specific areas that are defined by the local government.
Differences in number of fishers, income,
and total catch among swamps were found
(Table 1). Total catch ranged from 937 kg in
Muara Deles 4 to 30,788 kg in Rasau Jarang;
the highest catch per fisher was 6,117.5 kg
from Lebak Semunting. The swamp with the
lowest total catch, Muara Deles 4, was fished
all year long but by only two fishers.
During the dry season, about 110 ha of
shallow areas are utilized for rice cultivation
(Table 2). There were 57 farmers involved,
with a total rice production of 111 metric
tons. We assumed that 1 kg rice was valued at
Rp 5,000, and therefore, the average income
of rice farmers was Rp 10,445,000 per season.
Rice production per hectare was only about 1
metric ton in all villages.
Discussion
In Pampangan District, the swamps are managed in an integrated manner based on local
wisdom. During the wet season, the water bodies are managed as a common property where
all community members are allowed to exploit
fish resources. During the wet season, however, the allocation of selected fishing grounds by
integrated swamp management

Figure 1.—The map shows the location of the Pampangan District, Ogan Komering Ilir Regency,
South Sumatra Province, Indonesia, where field research was conducted between January and December 2012.
the local government is determined by an auction system whereby groups of fishers bid for
the right to fish.
During the dry season, the permanent
owners claim their plot of rice field for cultivating rice. However, some small pools within
the rice field areas are still inhabited by several
species of fish that can be used as broodstock
to supply young fish for the next wet season.
This result shows that the people living around
the swamps in Pampangan District understand
conservation and are planning for sustainable fisheries. Mustafa and Halls (2006) found
a similar result in Bangladesh where groups
of poor fishers were practicing sustainable
fisheries management by establishing fish
sanctuaries, controlling the use of destructive
fishing gears, and banning fishing during the
spawning season. In the Bangladesh study, annual fish production (in kg/ha) increased on
average by 13% per year. Waluyo and Supriyo
(2006) in adjacent swamp areas introduced a
new rice cultivar and new technology resulting
in higher rice production (3.6 metric tons/ha),
slightly higher than the average rice production in South Sumatra Province of 3.2 metric
tons/ha (Anonymous 2012) and much higher
than the 1 metric ton/ha found in this study.
The average individual gross income was
Rp 15,041,000 per season from fisheries, with

Average income of individual rice farmer per village
an average period of fishing of 9.2 months
(Table 1) and Rp 10,445,000 per season from
rice farming (7 months for a season of paddy
cultivation). The duration of the fishing period depends on the depth of swamp. In the
shallow swamp of Lebung Asem, the fishing
period only lasts 7 months, while in the deepest swamps (Muara Deles 4 and Lebak Kuro),
the fishing period is almost year-round. This
fact demonstrates the importance of fishery
activities to earn income to meet their day-today life.
The current study showed that the people
around the swamp areas understand integrated management of their resources based
on seasonal water availability and available
resources. Problems may emerge in the long
term due to increasing human population in
the area and increased competition for land,
water, and fishery resources. Local government needs to continue local fishing regulations, but more formal regulations on exploiting wild stock may need to be established.

sources and production of wastes, loss of
biodiversity, air and water pollution, and
increased pressure on arable land (Sharma 2008). Fishing communities often face
unique challenges to social and economic
stability as they rely on one particular natural resource for income and employment;
fishers are often characterized as economically impoverished and politically marginalized (Bailey and Pomeroy 1996).
Ita (1993) stated that the relationship between poverty and property rights over natural resources is complex. Poverty can lead to
a high dependence upon natural resources.
Exclusion from crucial resources following
changes to property rights regimes can act as
the main catalyst for increasing deprivation
and vulnerability of poor households. Accessing common property resources, local regulations, and conservation considerations are
main elements in sustainable development.
The traditional resource sharing system in
Pampangan District guaranteed continued access to food (i.e., fish and rice) for vulnerable
members of the community.

Ecosystem Approach to Fisheries and Aquaculture
in Southern Lake Malawi: Key Challenges during the
Planning Stage
FriDay nJaya*

Abstract.—This paper presents key challenges and lessons experienced during
the ecosystem approach to fisheries and aquaculture (EAFA) planning process for
the southern Lake Malawi, Mangochi district. This is in response to a near collapse
or serious decline of chambo (Oreochromis sp.) harvests in the fishing area due to
various ecological and socioeconomic problems such as overfishing, weak enforcement, habitat degradation, conflicting management policies, and deforestation. The
estimated annual chambo harvest recorded between 4,000 and 5,000 metric tons
in the early 1980s from southern Lake Malawi has now declined by almost 50%.
The reduced catch represents a loss of about 2 × 109 Malawi kwacha, which is approximately US$5.5 million using 2012 chambo beach prices. The decline in both
catch and revenue, therefore, justifies the need to identify policy and governance reforms for recovery and sustainable management of the fishery. Stakeholders recommended the development and implementation of an EAFA plan to guide rebuilding
the chambo populations. Aquaculture development within the fishing area was also
taken into account for increased supply of farmed chambo for food, nutritional security, and improved livelihoods of the local communities. Key challenges and lessons
from the EAFA development process include setting objectives, defining boundaries, extent of consultations, commitment of stakeholders, stakeholder participation,
overdependence on fishing, open-access nature of the fishery, conflicts, and limited
availability of data. The ecosystem approach to fisheries and aquaculture is a suitable management approach as it considers varied socioeconomic and ecological objectives of a user community.
Introduction
There is an emerging interest in the application
of an ecosystem approach to fisheries and aquaculture (EAFA) by various countries as a result
of continued declining capture fisheries resources. Malawi is one of the countries in Africa
that has developed an EAFA plan to guide management of fishery resources in the freshwater
ecosystem of southern Lake Malawi, mainly due
to the serious decline of the high-value chambo
(Oreochromis sp.), a cichlid. The estimated annual chambo harvests that were between 4,000

and 5,000 metric tons in the early 1980s from
southern Lake Malawi have now declined to
less than 2,500 metric tons (FAO 1993; Bulirani
et al. 1999; Banda et al. 2005; GoM 2014). The
main reasons for the chambo decline include
overfishing, habitat degradation, human population growth, and climate change and variability (Banda et al. 2005). The reduced catch represents a loss of about 2 × 109 Malawi kwacha,
which is approximately US$5.5 million using
2012 chambo beach prices (GoM 2012). The decline in both catch and revenue, therefore, justifies the need to identify policy and governance
reforms for recovery and sustainable manage-

ment of the fish and fisheries to improve livelihoods of the user community.
The ecosystem approach to fisheries and
aquaculture is defined as “a way of managing
fisheries and aquaculture that balances the different objectives of society (e.g., ecological and
economic objectives) by applying an integrated
approach across geographical areas that reflect
natural ecosystems” (Staples and Funge-Smith
2009:6). The ecosystem approach adopts the
concept of sustainable development that has
eventually replaced previous policies of development that focused on economic growth (FAO
2009). Sustainable development is a “process
for finding a balance between ecological wellbeing and human well-being so that development does not destroy the natural resource
base on which it is dependent, but avoids overprotection of resources that prevents rational
development” (FAO 2009:6).
The ecosystem approach to fisheries and
aquaculture can be applied as a means to achieving sustainable development, contributing to
food security and human development while
maintaining environmental integrity and enhancing social well-being by reducing intra- and
intersectoral conflicts in both a participatory
and consultative manner with the engagement
of relevant stakeholders (FAO 2009). It is recommended that when applying EAFA, the Code
of Conduct for Responsible Fisheries (CCRF)
should be considered as well (FAO 1995). The
CCRF provides a framework for responsible
fisheries, whereby the objectives of responsible
and sustainable fisheries and aquaculture can
be implemented at both local and national levels (FAO 2009). This paper outlines key challenges encountered during planning of an EAFA
for the southern Lake Malawi. Specifically, it
draws major lessons from the formulation of an
EAFA plan in 2013.
Southern Lake Malawi: Fisheries
and Aquaculture
Description of the southern Lake Malawi
ishery
The southern part of Lake Malawi (Figure 1) is
composed of the southwest arm and southeast
arm, both being the most productive fishing areas mainly for chambo and other cichlids. The
area lies between longitude 34°5’ and 35°5’
and latitude 13°5’ and 14o5’S and comprises
more than 10% of the total surface area of the
lake (28,800 km2; Kanyerere et al. 2010).
Status of the isheries
Both large-scale and small-scale fisheries operate in southern Lake Malawi. The large-scale
fisheries are mechanized operating trawls, purse
seines, or lift nets. The small-scale fisheries include all fishers that use engines of less than 20
hp or canoes without engines to catch fish. Gears
used in the small-scale fisheries include beach
seines, open-water seines, gill nets, fish traps,
longlines, and hand lines (Banda et al. 2001).
The 2013 frame survey showed that there
were 58,432 small-scale fishers recorded in
Malawi out of which 26.5% were from southern Lake Malawi. There were 26 licensed largescale fishers operating in southern Lake Malawi
in 2012 (GoM 2014). While there has been a
general increasing trend of fish harvests of most
of the fish species mainly from 2007 to 2011,
chambo harvests have remained low (Figure 2).
The fish harvest is largely composed of a
pelagic cyprinid, usipa Engraulicypris sardella,
which has masked the decline of commercially
valuable chambo harvest (Hara 2006, 2008;
Weyl et al. 2010, cited by Hara and Njaya 2016;
Tweddle et al. 2015). Changes in the fish composition were also reported by fishers, beach village committees1, beach village subcommittees,
traditional leaders, fish processors, and fish
traders during a field survey (Hara 1996; Njaya
2013). Other important harvested fish species
that are both cichlids include kambuzi (Lethrinops spp.) and utaka (Copadichromis spp.)
The decline in chambo species in southern
Lake Malawi has been reported since the late
1980s (FAO 1993). Excessive use of trawling
operations, nkacha (open-water seining), beach
A beach village committee is composed of people engaged in fishing-related activities (fishing,
processing, and trading) at a particular beach
while a beach village subcommittee is the elected
body of 10–12 members representing interests of
the beach village committee.

seines, and undersized mesh gill nets were the
reasons the Food and Agriculture Organization
of the United Nations cited, which were supported by respondents in a subsequent field
study (Njaya 2013). Other reasons include
habitat degradation, population growth, and
climate change and variability (Banda et al.
2005).
Status of aquaculture
The aquaculture subsector plays a significant
role in Malawi’s population as a source of food,
income and employment, with fish yields estimated at 4,000 metric tons annually (GoM
2014). Within Mangochi, there are 392 smallscale fish farmers owning 603 ponds and one
commercial aquaculture investor engaged in
both pond and cage farming. The small-scale
fish farmers collectively produce only 25 metric
tons per year. While the commercial fish farm
that was established in 2004 recorded weekly
harvests of about 10 metric tons in 2007 from
about 50 cages (Harley 2009).
Why Use the Ecosystem Approach
to Fisheries and Aquaculture in
Southern Lake Malawi?
In southern Lake Malawi, the commercially
valuable chambo is overexploited and no further increase in yield is expected (Banda et al.
2005; Hara and Njaya 2016). Annual chambo
harvests have been less than 2,500 metric tons
per year since the late 1990s (Njaya 2013; GoM
2014).
The fisheries sector contributes approximately 2% to Malawi’s gross domestic product
(de Graaf and Garibaldi 2014) and is a significant source of employment by directly employing about 60,000 fishermen, and indirectly
more than 500,000 people being engaged in fish
processing, marketing, net making, boat building, and engine repair (GoM 2012). Malawi’s
population was estimated to be 13.1 million in
2008, which resulted in decreased per capita
fish consumption from more than 12 kg in the
1970s to less than 7 kg in the 2000s (NSO 2008;
ecosystem approach to fisheries and aquaculture in southern lake malawi
GoM 2012). Additionally, Lake Malawi is considered a global biodiversity hot spot for wild fish.
Therefore, overuse of the resources and loss of
diversity pose serious socioeconomic and ecological threats to the livelihoods of the fishing
communities and the fishery resources.
Environmental and social impacts are vital
in aquaculture development. Considerations
should be made on some specific issues about
ecological services such as waste disposal and
sedimentation, and ecosystem services such
as water for fish and fisheries and domestic
use (GoM/FAO 2014). Pollution is also a threat
from cage culture in the southern Lake Malawi
if commercial aquaculture continues to expand
(Gondwe 2009). An ecosystem approach is essential to incorporate the views and priorities
of the stakeholders in the formulation of management plans.
Challenges and Lessons Gained
from the EAFA Planning Process
Several lessons were gained during the EAFA
planning process. Key ones included setting
objectives, defining boundaries, ensuring extensive consultations, getting commitment
and participation of stakeholders, reducing
overdependence on fishing, addressing the
open access nature of the fishery, reducing
conflicts, and improving the limited availability of data.
Setting policy objectives
The process of EAFA planning is challenging
when it comes to setting policy objectives, indicators, and targets to balance both human and
biological considerations, as EAFA requires
(Hara 2013). While an attempt was made in the
previous Chambo Restoration Strategic Plan
to set targets to achieve an annual harvest of
10,000 metric tons after a 10-year implementation period, in the EAFA plan, targets were
not set for rebuilding the chambo populations.
Appropriate data for modeling were limited,
implying that monitoring and evaluation of the
EAFA would be difficult.
The Government of Malawi and the Food
and Agriculture Organization of the United
329
Nations (GoM/FAO 2014) reported that during the community consultative meetings,
stakeholders agreed on the following as policy recommendations:
•
•
•
•
•
•
•
•
•
Adopt a multidisciplinary approach in
aquaculture to avoid a narrow fishery-sector perspective;
Poverty and food and nutrition security
goals and strategies should be explicit in
fisheries and aquaculture sector policy;
Ensure coherence between major crosssectoral development policies, programs,
and sectoral policy;
Develop a policy that seeks to maximize
resource rents and export revenues;
There should be a policy that supports local and regional market development and
local multiplier effects;
Small-scale integrated agriculture aquaculture (IAA) systems should be promoted
as a vehicle to enhance diversity, resilience, and output of the total farm system;
Small and medium aquaculture produc
tion systems (SMEs) can enhance local
economic development if well planned
and implemented;
Given the uncertainty of climate change
impacts, policies that promote a diversity
of production systems and products
should lead to greater economic and social
resilience than specialization on a small
range of products and systems; and
Training in various aquaculture systems
could provide new opportunities for unemployed people including the youth and
women for their improved livelihoods.
Setting objectives based on the above
recommendations was difficult mainly due to
inadequate and unreliable data for analysis
and subsequent policy guidance. Additionally,
without adequate capacity in terms of human
resources and funding, implementation of the
plan could be difficult. This situation could
be similar to the previous one whereby the
Chambo Restoration Strategic Plan was formulated but could not be fully implemented.
Staples and Funge-Smith (2009) also recommend the need to consider long-term political
will with sufficient resources and short-term
330

economic and social support for implementation of EAFA. They also noted that EAFA
requires commitment by stakeholders to address the challenge of making choices that
require trade-offs and compromises among
different sectors of society.
Deining boundaries
During formulation of the EAFA plan, it was
difficult to agree on the project boundary,
which could negatively affect resource allocation and implementation. Eventually, it
was generally agreed that at least all villages
along the lakeshore should be targeted (Njaya 2013). However, a broader boundary that
included the entire watershed would have
been more appropriate. Although some of the
watershed areas are far away from the lake,
they are important as sources of water and
conservation of vegetation to minimize soil
runoff and subsequent siltation of the influent rivers, which provide spawning grounds
for chambo and other fish species.
Extensive consultations
Community consultations are always recommended for any project formulation for buy-in
to facilitate its implementation (Staples and
Funge-Smith 2009). However, it might also be
costly if the process is not well planned. During
the EAFA plan development, some issues could
be tabled several times despite agreements
reached in the previous meetings. This arose
due to either having some participants who
were attending the meetings for the first time
or who did not remember previously agreedupon decisions.
Commitment and participation of
stakeholders
It is not easy to measure the commitment of
stakeholders, especially where community
meetings are financially supported by external agencies. Lessons could be drawn from the
past comanagement initiatives, which could
enable stakeholders to attend Lake Malombe
beach village community meetings largely due
to financial inducements provided by projects
(Hara 1996). The stakeholders must be made
aware that participation in the EAFA process is
in their best interest.
As much as EAFA was meant to accommodate various sectors at district level, participation during consultative meetings lacked
representatives from key sectors such as
water resources, marine, and agriculture. A
problem with this limited participation will
be weak support from the respective key sectors, which may affect project performance
and outcomes. It was also noted that there
was limited participation from the private
sector, local government, and women, yet
these groups are crucial in terms of their dependence on the fishery resources. Lack of
commitment and insufficient participation
will result in an EAFA plan that lacks ownership and will not be sustainable.
Reducing overdependence on ishing for
livelihood
Limited alternative livelihood strategies for the
fishing-dependent communities may undermine success of the EAFA. Hara (2008) also asserts that fishing in Malawi is considered a business venture and livelihood activity for many
people in their respective communities. Therefore, fisheries management measures such as
closed seasons, which limit the economic returns of fishers, are usually resisted, resulting in
noncompliance to fishing regulations.
Limited access to the ishery
The question about limited access was debated by stakeholders without conclusion
during several community consultative meetings. The main issue concerned identification
of other income generating activities for the
fishers that would be taken out of fishing. A
similar observation was made during the initial stages of the Lake Malombe participatory
fisheries management program in the early
1990s. An arrangement was made to compensate all open-water seine (nkacha) fishers that
were willing to stop fishing. However, after a
second thought, the plan was cancelled because it was considered unsustainable (Njaya
2002). It is yet to be seen if during the EAFA
implementation process a similar scheme
ecosystem approach to fisheries and aquaculture in southern lake malawi
would be considered to reduce the number of
fishers.
Reducing conlicts
Formulation of strategies to resolve various conflicts in the project site might be difficult. There
are conflicts between investors (cage owners)
and small-scale fishers that operate their gears
close to where cages are installed. There are
also conflicts between small-scale and largescale fishers in terms of fishing zones as illegal trawlers are seen fishing in shallow waters
where gill-net and seine fishers operate. Cases
of gill nets getting damaged are common, which
affects the livelihood of the small-scale fishers.
There is also promotion of irrigation along
influent rivers, which results in soil erosion and
siltation of rivers thereby reducing reproductive
capacity of cyprinids. And there are conflicts between small- and large-scale fishers on fishing
times and fishing areas. Trawling with largescale fishing boats with engines above 44 hp is
allowed from 0600 to 1800 hours while gill-net
fishers are allowed to set their nets from 1800
to 0600 hours. However, at times, the large-scale
fishers break the law by trawling at night, during which they cause damage to the set gill nets.
The small-scale fishers also complain about
continued illegal trawling operations within
the shallow areas (less than 18 m deep) of Lake
Malawi, which are not designated for large-scale
fishing (GoM/FAO 2014).
Improving limited baseline data
There were limited baseline data available
to enable a meaningful planning process, including development of indicators. Of particular importance were data to verify the
level of pollution, climate change impact on
the fishery resources and livelihoods of the
dependent communities, and biological and
stock level data on some offshore deepwater
fisheries species like catfish (Clarias spp. or
Bathyclarias spp.) that would provide a basis for fishing investment and interactions
among sectors and actors. Limited availability
of such data would lead to a poor EAFA plan
and consequently fail to address the declining
chambo harvests.
331
Conclusion
This paper has shown that the EAFA process is
difficult; hence, certain issues should be considered during its planning and implementation stages. Of critical importance is the need
to properly set policies, define the project site,
identify relevant stakeholders, and consider
property rights issues. There are emerging conflicts among fishers and between the fishers/
fish farmers and fishery managers that mainly
arise to due weak governance and enforcement
and conflicting policies.
Therefore, there is a need for governance
and policy reforms that would consider balancing human and ecological issues based on the
EAFA framework. The development of the EAFA
needs to consider rights-based management,
which is difficult to tackle within the smallscale fisheries for sustainable use of fisheries
resources (Hara and Njaya 2016). With political
will and adequate capacity in terms of skilled
manpower and financial resources, and active
and effective participation of the stakeholders,
EAFA seems a viable strategy for the recovery
of the declined chambo stocks that would contribute to the increased resilience of fisheries,
environment, and sustainable livelihoods of the
resources users.

Abstract.—The successor states to the former Soviet Union located in Central Asia and the Caucasus have substantial challenges in promoting sustainable
inland and small-scale fisheries. This is particularly true due to the impact of the
energy–water nexus that characterizes the domestic development challenges
of the eight countries. Soviet policies on water usage for misguided agricultural
development, including the cotton monoculture effort in Central Asia, depleted
important water flows to traditional fisheries while more recent pressure for increased hydroelectric generation capacity within new national borders threatens
to disrupt traditional fisheries and wildlife habitat. International tensions deriving
from competing claims to river flows constrain regional cooperation and portend
political and perhaps military conflict. There has been progress in regional economic integration among the Caspian basin littoral states, and in the context of the
Economic Cooperation Organization, the Shanghai Cooperation Organization, and
the emerging Eurasian Economic Union, but suspicions as to motives held by key
sponsoring states remain, as do perceived national interest conflicts. This paper
explores the constraints and prospects for regional cooperation and governance,
taking into account regional and bilateral tensions and drivers. Recommendations
for future progress are proposed.
Introduction
Achieving comprehensive global governance of
fisheries remains a challenging task. However,
regional and national governance structures
may provide insights for global fisheries governance. There are some important successes
in North America, particularly in the East (e.g.,
Atlantic Cod Gadus morhua, Atlantic lobster
Homarus americanus) and the West (Pacific
Salmon Oncorhynchus spp.). In addition, the
framers of the European Union (EU) Common
Fisheries Policy (CFP) can point to some success in remediating the collapse of fisheries
in northern European waters by reducing the
size of fleets in key countries and by enforcing

limitations on equipment, fishing seasons, and
catch size. This approach applies to coastal and
marine fishing more than inland fisheries, but
national regulation of the latter seems rather
effective in many EU countries, particularly
in the North. That being said, there are many
criticisms on the implementation of the EU CFP
by national authorities, and the call for much
more serious regional and global action has
been made with clarity and urgency (Lequesne
2004; Schechter and Blue 2011). The EU has
been relatively aggressive in addressing overfishing, and rightly so, given that the traditional fisheries of its members have been some of
the most overfished in the world. The health of
fisheries in the Mediterranean basin is also affected significantly by pollution that has a wide

range of residential, agricultural, and especially industrial sources, some of which are under
scrutiny and have been targeted for cleanup
(see European Parliament 2013 and European
Commission 2015).
This paper addresses several interrelated
questions about global fisheries governance.
What is the prospect for governance of regional inland fisheries in the post-Soviet successor
republics of central Eurasia? What, if anything,
can be learned from the (partial) success stories of fishery governance in North America
and Europe? Are the challenges similar? Are
there best practices and knowledge that can
be transferred? In short, I argue that the EU
CFP does provide some important lessons for
central Eurasia, but the regional tensions over
water and energy usage remain serious impediments. Moreover, there are related domestic economic and political constraints, evident
since independence, which both have helped to
worsen the collapse of inland fisheries in the
region and now stand in the way of short-term
remediation. The promoters of the Eurasian
Economic Union have the ambition to mimic
the sectoral policies of the European Union,
including water, energy, and fisheries policies,
but the commitment of resources and policy
convergence is minimal, to date. Indeed, the
Central Asian and Caucasus Regional Fisheries
and Aquaculture Commission (CACFish) within the Food and Agricultural Organization of
the United Nations (FAO) represents the most
promising institutional forum at present in the
region, despite its recent inception.
Origins and Dimensions of the
Inland Fisheries Crisis in Central
Eurasia
The collapse of inland fisheries in Central Asia
and the Caucasus derives in large part from
the energy–water nexus in the region (see International Crisis Group 2002; World Bank
2004; FAO 2009; Thorpe et al. 2009; Breckle
et al. 2012). Countries with abundant water
resources are deficient in fossil fuel resources
and vice versa, so there is pressure on waterrich countries to increase hydroelectric generation capacity, which is opposed by downstream
oil-rich and gas-rich countries that require
substantial water flows for elaborate irrigation
efforts of cotton crops (see International Crisis
Group 2005). Added to this imbalance is the
legacy of misguided, noxious Soviet agricultural and environmental policies that diverted
water resources for unsustainable agricultural
production goals yet permitted unfettered industrial pollution of rivers, lakes, and seas. The
Soviet water and energy transmission network
may have made some sense in Moscow for autarkic economic and heavy industrialization
goals under Stalin and his immediate successors, but the damage done to the natural environment and the prospect for sustainable habitation and prosperity in the Soviet successor
republics was and is appalling. The network of
water and energy transmission managed centrally from Moscow in Soviet times has disintegrated into decaying infrastructures managed
by national authorities beset with conflicting
domestic imperatives and seemingly myopic
policy priorities and been complicated by limited economic resources.
The dimensions of the inland fisheries crisis in Central Asia and the Caucasus are startling, as Tables 1 and 2 clearly show. There was
a dramatic drop in the fish harvest in all countries in the region from 1989 to 2008. Armenia seems to be the least affected of the eight
countries, but even in this country the 2008
harvest was less than 78% of the 1989 harvest.
In Azerbaijan, Kyrgyzstan, and Tajikistan, harvest dropped to below 10% of the 1989 levels,
2.9%, 6.9% and 4.9%, respectively. By 2012,
several countries had made significant progress in achieving harvest levels similar to the
1989 levels (Table 2). Some of this progress,
especially in Armenia and Uzbekistan, is attributable to aquaculture development, rather
than by restoring inland fisheries (Table 2).
The reasons for the reduction in harvest
are complex and include a number of distinctive, country-specific factors. Thus, there is no
space for a full country-by-country analysis in
this modest paper. The four key reasons that
apply to several of these countries are delineated to explain the continuing roadblocks to
remediation through improved regional cooperation.

First, the collapse of the Soviet economy
was dramatic and far-reaching. With the downfall of the Soviet Union as a political entity, the
tasks for each successor state to address the
dual challenges of building a new political and
economic system were immense. The common western model of democratization and
economic liberalization was largely bypassed
in this region, except perhaps for Georgia, beginning with its 2003 Rose Revolution. This
resulted in President Eduard Shevardnadze, a
holdover from the Soviet era, being forced to resign, leading to presidential and parliamentary
elections in which Mikeil Saakashvili’s United
National Movement party won. When some elements of the suggested reforms were adopted
in most other post-Soviet countries, these were

only modestly effective. The literature explaining this story is detailed but too large to address
here systematically (see Lavigne 1999; Aslund
2002, 2007; Peimani 2002; Olcott 2005, 2010,
2012; Overland et al. 2010). The predominant
system now in place is aptly depicted as “patronal politics” by Henry E. Hale (2015).
Second, the long-term negative environmental impacts of policies that began under
the Soviet regime affected all eight successor
countries to some extent, destroying habitat
and reducing, and sometimes eliminating, formerly productive fisheries. These actions were
long in the making and not easily remediated.
However, the most striking fact is that until recently, and then only partially, none of the successor countries’ regimes sought to address the

harmful effects of wasteful irrigation used to
grow inappropriate crops, like cotton and rice
in excessively arid regions, polluting practices
that had disrupted fish habitat, or sought to
pursue less expansive hydroelectric generation
strategies. The desertification of the Aral Sea
in Kazakhstan and Uzbekistan is a well-publicized case study and the most striking example
of this tragic set of policies. The elimination of
this formerly productive fishery had obvious
direct impacts on the livelihoods of the fishers,
but the nearly complete destruction of the subregion and its broader population through the
secondary impact of soil encrusted with salt
and poisoned by pesticide runoff, which then
spread through the air in the common regional
dust storms, was nothing short of devastating.
Breckle et al. (2012) and Micklin et al. (2014)
provide a detailed analysis and assessment of
this fishery, but it still remains clear that newly
independent governments generally chose not
to repeal many Soviet policies and the system
that had wreaked havoc on fish habitat and the
broader environment (FAO 2003, 2009). The
Soviet imperial policies of autarky and self-sufficiency (especially the policies behind the cotton monoculture focus in Central Asia) were no
longer in play as a political justification for bad
economics and agriculture, especially in the increasingly globalized economy of the post-Cold
War world (Figure 1).
Third, one can argue that the political leadership in each country was distracted by more
pressing governance and economic development challenges in the early years of independence. For Georgia and Tajikistan, civil war
raged on during the early years. For Armenia
and Azerbaijan, the devastating conflict over Nagorno-Karabakh was a serious distraction and
obvious impediment to regional cooperation
on remediating the pollution of key transborder
river systems. More subtle, but nonetheless extant, was the fact that most of the regimes were
highly focused on other elements of economic

agricultural irrigation practices, and current and projected water infrastructure with potential risk to the

regional governance of inland fisheries in central eurasia
and development policies. Fishery policy was
not a high priority, nor was general agricultural
reform and rural development. One notorious
example of this posture in Sakashvili’s Georgia
was the widely quoted, bold claim made by a
central bank official that rural farmers should
“move to the cities,” a statement offered in response to complaints about the growth in rural
poverty from the evident neglect of agricultural
development in a republic formerly known for
its agricultural productivity during the Soviet
era (Echanove 2013; Archilochus Melikadze,
Agricultural Projects Management Agency and
Eric Livny, International School of Economics
at Tbilisi State University, personal communications). The new economy of Georgia was focused on the global information and communications revolution, not resuscitating something
mundane such as food production.
The fourth set of factors that explain the
collapse of inland fisheries has to do with the
crucial energy–water nexus operative in much
of the Central Eurasian region. Countries with
abundant water resources (e.g., Georgia, Kyrgyzstan, and Tajikistan) are deficient in fossil
fuel resources, while oil- and gas-rich countries (e.g., Azerbaijan, Kazakhstan, Turkmenistan, and Uzbekistan) are downstream from
and dependent on the water-rich countries
for agricultural irrigation and fisheries. The
pressure on water-rich countries to increase
hydroelectric generation capacity is clear. But
such action is often opposed by downstream
oil- and gas-rich countries, especially in Central Asia, which claim a right to substantial
water flows for elaborate irrigation efforts in
support of the cotton monoculture, and secondarily for fishery rehabilitation (ICG 2005).
Armenia has modest water resources, mostly
from the mountains of Turkey, but has no significant oil or gas reserves. In some ways, it is
the least independent of the Central Eurasian
countries, but Armenia enjoys substantial political and military support from the Russian
Federation and equally substantial economic
support from the Armenian diaspora.
Countries with abundant water resources
have generally not been able to monetize their
water resources, at least not in comparison with
what the oil- and gas-rich countries have been
337
able to do. Indeed, schemes to compensate water
drawdown with energy resource transfers, the
subject of serious negotiation and some agreements, most notably between Uzbekistan and
Tajikistan, have not worked well (World Bank
2004). The Uzbeks have threatened recourse to
military action in response to potential cuts in
water flows (ICG 2002). The energy–water nexus is clearly a challenge, as Tajikistan and Kyrgyzstan, on the one hand, and Uzbekistan and
Kazakhstan, on the other, seem to court serious
conflict over the hydroelectric generation plans
of the former in competition with the downstream irrigation needs of the latter. Irrigation
needs are problematic due to aging and poorly
maintained structures, harsh climate, and soil
quality deficiencies, but they are also driven by
the surprising longevity of Soviet cotton monoculture in the region. A Russian or Chinese role
in helping to reduce tension and remediate the
conflicts of interest, which the Soviets helped to
create, would be a valuable contribution to the
region, whether it comes bilaterally or as part of
a larger multilateral effort.
Georgia and Tajikistan offer the best examples of a predominant focus on hydroelectric
generation capacity development, sometimes
without due consideration of fish habitat impacts. Georgia has been engaged in a sustained
effort to expand its hydroelectric power generation capacity for many years. A large number of construction and rehabilitation projects
have been initiated. Various government assessments suggest that at least 15 new hydropower plants should be constructed because at
present, Georgia is using less than a fifth of its
hydroelectric power potential (Figure 2). The
plan is to provide sustainable (i.e., year-long)
power to meet Georgia’s growing demand, as
well as to increase substantially its electricity
exports. Georgia is fortunate to have 26,000
rivers, constituting 60,000 km in total length,
many of which originate in mountainous terrain. Estimates suggest that at least 300 rivers are suitable for hydroelectric development. Georgia’s 2008 Renewable Energy Plan
was quite ambitious in this respect. Financing
the plan remains a serious challenge, making
Georgia dependent on external funding sources like the World Bank and the Asian Devel-

Madison College, Michigan State University).
opment Bank, which require environmental
and social impact assessments, to the frustration of the aggressive energy project planners. There is, however, little or no attention
to impact on fish habitat in the hydroelectric
expansion plans.
For Tajikistan, the key dam constructions
are the Rogun and Sangtuda hydropower projects (Figure 1). Rogun is set to solve Tajikistan’s
annual winter energy crisis with an expected
installed capacity of 3,600 MW. Unfortunately,
it may also displace 42,000 people from surrounding mountain villages. The World Bank
has not yet committed financing to the project, but the Tajik government appears ready
to complete it eventually in any case, perhaps
with Russian or Chinese support.
Finally, it is often argued that the key obstacle poorer Central Eurasian states face is
the lack of investment funds to modernize and
rehabilitate neglected aquaculture and inland
fishery equipment. Indeed, there is a tendency
to focus the limited financial and manpower resources on crops, like rice, tobacco, and wheat in
Kyrgyzstan (FAO 2007) and urban development
and hydroelectric generation projects in Georgia
(FAO 2005, 2010). Inadequate funding is likely
a long-term constraint, but regional cooperation to share and regulate water resources more
equitably and sustainably is not impossible (see
World Bank 2004). Aquaculture is under modest development in several Central Eurasian
countries, most notably Azerbaijan, Georgia, and
Kazakhstan, with the aim of restoring more selfsufficiency and diversity in food production. But
the prospect for a substantial increase in public
funding for expanded production in the current
climate of low oil and gas prices is dim.
regional governance of inland fisheries in central eurasia
Conclusion
Are there regional institutional options that
might help facilitate international cooperation on inland fisheries in Central Eurasia?
The Commonwealth of Independent States,
the Shanghai Cooperation Organization, the
Economic Cooperation Organization, the Eurasian Economic Union, and CACFish are the
principal institutional candidates, but frankly
there is little reason for confident optimism in
each institution for a variety of reasons. This
results from the weakness of the institutions
now available in the Central Eurasian region,
and the lack of perceived common interest and
trust among the successor states that constitute the membership(s). Certainly, there is no
common willingness to accept supranational
authority and effective regulation to the extent
that has emerged with the EU CFP, and while
some individual states in Central Eurasia enjoy
substantial income from oil and gas exports at
times, the prospect for a substantial regional
pool of financial resources for investment in
fisheries remediation and sustainability projects seems unlikely in the short term. Scientific
expertise and technical assistance possibilities
are available, but financial resources and political will are in short supply.
The Central Asian and Caucasus Regional
Fisheries and Aquaculture Commission is in
some ways the most promising institutional
development in the region for tackling the
fisheries crisis. It is not burdened with the
political agendas of key regional powers like
China, Russia, Iran, and Turkey, and it is backstopped with the technical expertise and experience of FAO. The Central Asian and Caucasus Regional Fisheries and Aquaculture
Commission began its work in 2010 after Armenia, Kyrgyzstan, and Tajikistan ratified the
CACFish founding agreement. There now have
been several meetings of the CACFish Technical Advisory Committee, which have reviewed
various aspects of the status of fisheries and
aquatic resources in the region. The Central
Asian and Caucasus Regional Fisheries and
Aquaculture Commission has the power to impose binding management and conservation
recommendations, but it has mainly focused
339
on data collection and review, such as its inland fisheries stock assessment discussed in
Bishkek in April 2014. The membership now
includes Azerbaijan and Turkey. Georgia, Kazakhstan, Mongolia, Ukraine, and Uzbekistan
also attended the third session of the commission held in Baku, June 2–4, 2014 (FAO 2012,
2014a, 2014b).
The way forward for Central Eurasia’s
inland fisheries is relatively straightforward,
albeit politically challenging: (1) adopt and
enforce regional and complementary national
rules on fishing equipment and catch limits to
curtail overfishing; (2) address transborder
water sharing, conservation, and management aggressively on a regional basis before
the resources are degraded beyond recovery;
(3) continue to expand aquaculture research,
development, and commercialization to replace collapsed fisheries that cannot be revived; and (4) expand essential hydroelectric
generation capacity in Kyrgyzstan and Tajikistan but do so within a framework of environmental impact assessment that includes consideration of alternative strategies to reduce
potential fish habitat loss, as well as efforts
to limit human dislocation and transborder
tensions. The way is straightforward, but the
required level of political commitment and
compromise will not come easy given the nature of the present Central Eurasian regimes
(Hale 2015).

Abstract.—For decades, inland fisheries and their value have been overshadowed by marine fisheries dominated by the commercial sector. However, there is
growing recognition that inland capture fisheries harvest is substantial. Indeed,
inland fisheries generate many ecosystem services, most notably their contributions to food security and livelihoods. Here, we present the outcomes of a conference where scientists, resource managers, policymakers, and community representatives from across the globe gathered to discuss inland fisheries. What emerged
from discussions at the conference is affectionately termed “The Rome Declaration,”
which provides a forward-looking call to action characterized by 10 recommendations: (1) improve the assessment of biological production to enable science-based
management, (2) correctly value inland aquatic ecosystems, (3) promote the nutritional value of inland fisheries, (4) develop and improve science-based approaches
to fishery management, (5) improve communication among freshwater users, (6)
improve governance, especially for shared water bodies, (7) develop collaborative
approaches to cross-sectoral integration in development agendas, (8) respect equity
and rights of stakeholders, (9) make aquaculture an important ally, and (10) develop
an action plan for global inland fisheries. We trust that the outcomes from this conference (including “The Rome Declaration”) will serve as a catalyst for sustained
action by the global inland fisheries community to ensure that fish and fisheries are
accounted for and incorporated into broader water-resource management discussions and frameworks.
Context
Inland fisheries took center stage in January
2015 in Rome at the Food and Agriculture Organization of the United Nations (FAO) headquarters when scientists, resource managers,
policymakers, and community representatives
from across the globe gathered. Participants
discussed the current state of inland fish and
fisheries, explored the interactions among the
sectors that impact freshwaters, and developed
recommendations for the governance and management of sustainable aquatic ecosystems to
ensure that inland fish and fisheries prosper to
continue to support livelihoods and food security (FAO and MSU 2016). As discussed by Beard
et al. (2016, this volume), this requisite global
conference was long overdue, despite inland
fish and fisheries generating crucial ecosystem
services (Cowx and Portocarrero Aya 2011;
Lynch et al. 2016, this volume).
For many decades, inland fisheries and
their value have been overshadowed by marine fisheries dominated by the commercial
sector (Cooke et al. 2014; Youn et al. 2016, this
volume). However, there is growing recognition that inland capture fisheries harvest is
substantial (Welcomme et al. 2010; Welcomme
2016, this volume). Nevertheless, estimates
of global inland fisheries harvest have been
plagued with problems and may underestimate actual harvest by several-fold (Bartley et
al. 2015). De Graaf et al. (2015) suggested that
a major constraint on data collection in inland
fisheries results from their dispersed nature,
which cannot be fully assessed using traditional approaches. As such, Lymer et al. (2016a, this
volume) used a novel approach to estimate net
primary production by continent and aquatic
habitat type and thereby generated estimates
of potential global inland fisheries annual production. The authors estimated that the global
theoretical potential annual inland fisheries
production is, on average, 6.5 times higher
than the official catch data submitted annually
to FAO and emphasized that the potential economic and social value of inland capture fisheries and their contribution to food security and
livelihoods is much higher than estimated by
the harvests currently reported.
The reason that so much effort has gone
into better estimating global, regional, and local
inland capture fishery harvest is that without a
concept of harvest, it is difficult to make direct
comparisons to the marine realm or accurately
characterize and value the socioeconomic or
from ideas to action
nutritional benefits arising from these freshwater resources (Beard et al. 2011). As such,
inland fisheries and inland aquatic ecosystems
are often forgotten in high-level policy decisions, including international agreements and
instruments related to water resource management. This has become exceedingly clear
as major watercourses that transcend developing countries in South America (Amazon),
Africa (Congo), and Asia (Mekong) face the
prospect of intense hydropower development
and where the sustainability of inland fish and
fisheries (and the peoples they support) are
considered unimportant relative to the potential for hydropower development (Winemiller et al. 2016). For example, the replacement
costs for lost protein and nutrients from inland
fisheries harvest in the Mekong River are significant (Lymer et al. 2016b, this volume) yet
these human costs of hydropower development are rarely considered (Barlow 2016 this
volume). Even the tiniest of fish in inland waters can provide essential protein, minerals,
and vitamins to support children during critical life periods in developing countries (Roos
2016, this volume), yet the value of such fisheries are often dismissed when compared to the
economics of hydropower or other water users
(e.g., irrigation, industrial manufacturing). Opportunities certainly exist for better interfacing
inland fish production with crop production
(e.g., integrated fish–crop production systems;
Phosa 2016, this volume) and supporting the
development of inland aquaculture (Ibengwe
2016; Kahn 2016; both this volume).
Unlike marine fisheries that are traded globally and where exports can be easily tracked and quantified (Youn et al. 2016),
most inland fisheries are small-scale fisheries
where products are sold, bartered, or traded
locally (Welcomme 2016). As such, those that
attempt to estimate harvest and consumption in such regions are often forced to rely
on household surveys implemented as part
of agricultural monitoring programs (FungeSmith 2016; Simmance 2016; both this volume). Such approaches hold much promise for
biological monitoring (Cooke et al. 2016, this
volume) and determination of values of inland
fisheries (Funge-Smith 2016). If coupled with
345
other more traditional fisheries monitoring
approaches that involve fisheries dependent
and independent data (see Koehn 2016, this
volume), resource managers have the potential to be able to make meaningful advances in
the determination of global inland fish production and fisheries harvest and their contribution to food security and nutrition while also
providing local fisheries managers with the
information requisite to effectively manage
and restore inland fish and fisheries (Koehn
et al. 2016). Beyond the biology, there is also a
need to characterize and recognize values that
are more difficult to quantify but exceptionally
important, such as ecosystem monitoring, cultural values, traditional knowledge, and rights
of indigenous peoples (Boisneau 2016; Lumley
et al. 2016; both this volume).
Although the concept and practice of fishery management is common, in reality fish
are simply a small part of aquatic ecosystems
and are best managed in the context of integrated water resource management (Unver et
al. 2016, this volume). Watersheds are coupled
social-ecological systems and thereby require
a logical, coordinated approach to assessment,
planning, and management. Of particular note
is the fact that watersheds connect the waters
with the surrounding landscape (Hynes 1975)
and thus demonstrate effectively the intimate
connection between people, their activities
on the landscape, and the aquatic ecosystem,
including fish. Although in theory the concept
of integrated water resources management
(or watershed management or some form of
ecosystem management) is appealing, in practice there are many challenges with its implementation, especially at the scale of extensive
river basins that transcend political boundaries (e.g., Baigún et al. 2016, this volume). Some
have attempted such efforts but done so on a
smaller scale (e.g., at the level of the Pampangan Swamp in Sumatra [Muthmainnah and Prisantoso 2016, this volume] or Lake Milawi in
east Africa [Njaya 2016, this volume]), which is
useful for engaging the local community (e.g.,
in comanagement) but often fails to recognize
external influences (e.g., whatever is happening upstream or on land; Lynch et al. 2016).
What is clear is that effective governance struc-
346
cooke et al.
tures at institutional and spatial scales need to
incorporate all sectors involved in water resource use, not only to ensure that fisheries are
managed effectively, but to ensure the sustainability of freshwater ecosystems (Bartley et al.
2016, this volume). Comanagement or local
management is necessary but needs to occur at
scales that enable holistic perspectives (Lumley et al. 2016).
As the global conference on inland fisheries drew to a close at the end of January 2015,
those that participated considered this to be
the start of a journey rather than the terminus. In an effort to maintain, and indeed accelerate, progress related to more effective
consideration of inland fish and fisheries in
freshwater resource allocation decisions, a
group of thought leaders assembled at the
conclusion of the conference to consider next
steps. What emerged from those discussions
is affectionately termed “The Rome Declaration,” which provides a forward-looking call
to action characterized by 10 steps and implementation recommendations (FAO and MSU
2016). These steps and recommendations are
general and not targeted to specific groups;
however, numerous entities at various levels
of government and society will need to work
together for effective implementation. The
recommendations build on, inter alia, the
principles contained in the Convention on
Biological Diversity, the Voluntary Guidelines
for Securing Sustainable Small-Scale Fisheries in the Context of Food Security and Poverty
Eradication (FAO 2015b), and the Voluntary
Guidelines on the Responsible Governance of
Tenure of Land, Fisheries and Forests in the
Context of National Food Security (CFS 2012).
As detailed in those instruments, for effective
management and sustainability of freshwater
ecosystems and their fisheries, it is critical to
recognize and incorporate the rights of fishers, women, traditional resource users, and
indigenous people into all levels of decision
making. Past development of inland water
resources has often occurred in the absence
of such recognition and deprived key groups
of culturally and economically important connections and access to aquatic ecosystems
and the services they deliver.
Ten Steps
The 10 steps are presented in an order that
represents a logical progression. For example,
it is first necessary to know what exists and
how valuable it is before information can be
communicated cogently to all sectors (in the
absence of such information, a precautionary approach is required). Moreover, fisheries
cannot be integrated into cross-sectoral governance if they cannot be effectively managed
within the fishery sector. Taking these 10 steps
will be part of a path towards a world where
people can responsibly use and enjoy freshwater ecosystems and their fishery resources
today and for years to come.
1. Improve the assessment of biological
production to enable science-based
management
Accurate and complete information about fishery production from inland waters is lacking at
local, national, and global levels. Governments
often lack the resources or capacity to collect
such information due to the diverse and dispersed nature of many inland fisheries. There
is much scope for developing and refining biological assessment tools to facilitate sciencebased management.
2. Correctly value inland aquatic ecosystems
The true economic and social values of healthy,
productive inland aquatic ecosystems are often overlooked, underestimated, and not taken
into account in decision making related to land
and water use. Economic and social assessment is often difficult and valuation often limited. In most cases, especially in the developing
world, inland fisheries are part of the informal
or local economy, so their economic impact
is not accurately measured in official government statistics.
3. Promote the nutritional value of inland
isheries
The contribution of inland fisheries to food
security and nutrition is higher in poor, foodinsecure regions of the world than in many developed countries that have alternate sources
from ideas to action
347
of food. Good nutrition is especially critical
in early childhood development (i.e., the first
1,000 d). Loss of inland fishery production will
undermine food security, especially in children, in these areas and put further pressure
on other food-producing sectors.
nance structure that holistically addresses the
use and development of the water and its fishery resources. This often results in decisions
made in one area adversely affecting aquatic
resources, food security, and livelihoods in another.
4. Develop and improve science-based
approaches to ishery management
7. Develop collaborative approaches to
cross-sectoral integration in development
agendas
Many inland water bodies do not have fishery
or resource management arrangements that
can adequately address sustainable use of resources. Where management arrangements
exist, compliance and enforcement are often
minimal or nonexistent. This may result in excessive fishing pressure, decreased catch per
unit effort, and conflicts between fishers, as
well as changes in the productivity of fishery
resources. In some areas, reductions in fishing
capacity will be required. To facilitate fishery
management, it will be important to improve
access to and promote better sharing of data
and information about inland fisheries supporting the assessment–management cycle.
5. Improve communication among
freshwater users
Information on the importance of the inland
fishery and aquaculture sectors is often not
shared with or accessed by policymakers,
stakeholders, and the general public, thereby
making it difficult to generate political will
to protect inland fishery resources and the
people that depend on them. Moreover, many
misconceptions exist on the needs and desires
of fishing communities. Building from the
small-scale fisheries guidelines (FAO 2015a)
and other relevant instruments, use appropriate and accessible communication channels
to disseminate information about inland fish,
fishers, and fisheries to raise awareness of inland fisheries’ values and issues, to alter human behavior, and to influence relevant policy
and management.
6. Improve governance, especially for
shared water bodies
Many national, international, and transboundary inland water bodies do not have a gover-
Water-resource development and management discussions very often marginalize or
overlook inland fisheries. Therefore, tradeoffs between economically and socially important water-resource sectors and ecosystem services from inland water systems often
ignore inland fisheries and fishers. Development goals based on common needs (e.g.,
clean water and flood control) can yield mutually beneficial outcomes across water-resource sectors.
8. Respect equity and rights of stakeholders
Lack of recognition of the cultural values, beliefs, knowledge, social organizations, and
diverse livelihood practices of indigenous
people, inland fishers, fish workers, and their
communities has often resulted in policies
that exclude these groups and increase their
vulnerability to changes affecting their fisheries. This exclusion deprives these groups of
important sources of food, as well as cultural
and economic connections to inland aquatic
ecosystems.
9. Make aquaculture an important ally
Aquaculture is the fastest-growing food production sector and an important component
in many poverty alleviation and food security
programs. It can complement capture fisheries (e.g., through stocking programs) by
providing alternative livelihoods for fishers
leaving the capture fisheries sector and by
providing alternative food resources. It can
also negatively affect capture fisheries (e.g.,
introduction of invasive species and diseases)
through competition for water resources, pollution, and access restrictions to traditional
fishing grounds.

cooke et al.
10. Develop an action plan for global inland
isheries
Without immediate action, the food security,
livelihoods, and societal well-being currently
provided by healthy inland aquatic ecosystems
will be jeopardized, risking social, economic,
and political conflict and injustice. Therefore,
it is necessary to develop an action plan based
on the above recommendations to ensure the
sustainability and responsible use of inland
fisheries and aquatic resources for future
generations. The action plan should involve
the international community, governments,
civil society organizations, indigenous peoples
groups, and private industry and include all
sectors using freshwater aquatic resources.
Conclusion
From the outset, the intent (see Beard et al.
2016) was clearly to have a global cross-sectoral conference, involving and integrating the
other freshwater resource sectors (e.g., agriculture, energy, and drinking water). Despite
the best efforts of all involved, there were inherent difficulties in doing so. Of particular
note was the difficulty in establishing integrated cross-sectoral management of freshwater
resources. Although a laudable goal, this was
not achieved, and thus, more work is needed.
In the interim, fisheries professionals need to
take a leadership role in this initiative on local scales (e.g., water body, subwatershed) in
an effort to sustain global freshwater fish and
fisheries. Hopefully, lessons learned at the
local scale on how to implement integrated
cross-sectoral management of freshwater resources (including fish) will provide insight on
how to scale up such efforts to larger geopolitical contexts. It is also worth noting that this
conference was the first step in a long process
that will take time to fully realize. There were
certainly meaningful outcomes and collective
interest in real action (see “The Rome Declaration” above) and we trust that this will serve
as a catalyst for sustained action by the global
inland fisheries community to ensure that fish
and fisheries are accounted for and incorporated into broader water resources management
discussions and frameworks.

This publication is a compilation of presentations and recommendations resulting from the Global Conference on Inland Fisheries: Freshwater, Fish and the
Future, convened at the headquarters of the Food and Agriculture Organization
of the United Nations in Rome, Italy in January 2015. This conference on the
function and importance of inland isheries brought together experts from various sectors and more than 40 nations, including a large number of early career
scientists and women. This diverse group was essential because the challenges
facing inland isheries require new cross-sectoral approaches and the involvement of all stakeholders in freshwater resources.
All too often, the critical role of inland isheries in food security and livelihoods
is inappropriately valued, over even overlooked, when policymakers decide on
the use, allocation, and alteration of freshwater resources in their communities
and nations. The information in this book highlights this importance of freshwater ish, their habitats, and their isheries to society. It aims to describe the
current state of the knowledge and future information needs that will allow for
isheries sustainability, which in turn directly or indirectly provides for the health,
well-being, and prosperity of human communities throughout the world.
The purpose of this book, and the global conference is to elevate the signiicance of freshwater isheries throughout the world so that ishery managers and
the people that depend on freshwater isheries will have a voice when policymakers make decisions that impact their viability and productivity. It represents
a unique output on inland isheries from a global perspective that addresses
biological and sociocultural assessments, drivers, and governance issues. Based
upon the presentations and discussions of the conference, a set of recommendations were developed, “The Rome Declaration: Ten Steps to Responsible
Inland Fisheries,” which will provide a foundation for a new international approach to ensure that the true value of inland isheries is recognized in resource
allocation decisions.
