A global crisis of high feed prices, expansion of the aquaculture sector, and the increasing proportion of farmed fish have run into a decrease in the supply of fishmeal products. Therefore, scientists have redoubled efforts to discover alternatives and more renewable ingredients for aquafeeds worldwide. The goal has been to protect ecosystems and increase economic viability based on enhanced efficiency of production facility outputs and nutritional efficiency. A key challenge though is sourcing sustainable, renewable protein ingredients. This chapter reviews the advances, novel ingredients, and new techniques that serve the mission for the future of aquafeed research on alternatives for fishmeal to achieve global aquaculture sustainability, with a focus on partial or full replacement of fishmeal, especially in the feed of tilapia.

This ash typically is disposed in large evaporation ponds, which leave vast ash beds and volumes of saline leachate. Restoration of vegetation and wildlife habitat on ash ponds and other impacted areas is complicated by a lack of high quality water for irrigation. I used saline water generated by plant operations to irrigate species of halophytes. These salt tolerant plants were used to revegetate ash ponds and other degraded sites at two generating stations. Once vegetation was established, it provided habitat for wildlife, forage for domestic ruminants, ornamental landscaping, controlled fugitive dust and reduced wastewater disposal costs. At the Four Corners Plant in New Mexico, 16 accessions of Atnplex canescens were tested in a common garden experiment irrigated with saline water recovered from a drainage system collecting leachate from the plant's ash ponds. Accessions from latitudes similar to Northern New Mexico grew faster and had a higher percentage of survival than accessions from more southern or northern locations. Accessions best adapted to an area would be preferable for revegetation projects. I also studied several species of halophytes (Atnplex canescens, A. lentiformis, Prosopis velutina and Paspalum distichum) planted at the Ocotillo Plant in Tempe, Arizona and irrigated with saline water from the cooling system. The vegetation had high survival and growth rates after transplanting. Ground cover increased from 5% to 60%. Surveys of wildlife were conducted pre and post-transplantion. Birds, rabbits and lizards were significantly more numerous in experimental planted areas than in untreated control plots. Rodent populations were not significantly different between treatments. Halophytes can be used to revegetate areas adjacent to electrical power plants and irrigated with saline waters that are normally discharged. Devoting saline water to revegetation irrigation is a cost effective method of disposal compared to evaporation ponds. Plantings attracted several forms of wildlife. Birds, rabbits and lizards specifically used the plants for food, cover and nesting. I developed an economic analysis which compares costs and benefits of restoration projects using halophytes irrigated with saline wastewater.hydrology collectio

Environmental groups as well as the general public have also recognized the fish as one of the “greenest” aquaculture products. Tilapia feed on a low trophic level and require little if any fishmeal or fish oil in feed. Due to tilapia’s overall hardiness, very few drugs or chemicals are used in normal production. For tilapia, the most important quality issue is off-flavor in fish that have been exposed to the organic compounds geosmin or methylisoborneol during production. Safety issues are of lesser concern, but include the potential for hormone residues from sex reversal, the possibility of antibiotic residues, concerns over the use of carbon monoxide or liquid smoke as a preservative and color enhancer in frozen fillets, and the general potential for contamination during production or processing. ...

The main goal of the project was to demonstrate the direct benefits to the poor that could result in by improving the capacity of trainers and by supporting the application of this capacity in extension service delivery. Under the project, a group of selected DOF officers (extension workers) were sent to the Asian Institute of Technology (AIT) based in Thailand for training on mono-sex hatchery management and cage culture of tilapia in 2001. Thinking to apply the knowledge and skills gained through 4-week hands-on training, one of them upon his return to workplace (Fish Breeding and Training Center, Raipur) collected F6 generation of Genetically Improved Farmed Tilapia (GIFT) from Bangladesh Fisheries Research Institute (BFRI) which was originally from ICLARM, now World Fish Center. Applying selective breeding high quality seeds of GIFT were produced and 3.7 million seeds were distributed among the farmers during 2002. By motivating the private farmer and providing the technical support, a mono-sex tilapia hatchery and grow-out farm (Ambar Fisheries) was established in Laxmipur district in 2002. In the same year, cage culture was promoted among private entrepreneurs. As a result, 40 cages (6mX3mX1.5m=27m) were set in the Dakatia River in Chandpur. Following the success, cage culture expanded to Laxmipur district in 2006 due to which demand for seed increased. Under the technical assistance of the same person, Pioneer Fisheries and hatcheries started its operation in Chandpur district in the same year. After the success of these first few hatcheries which produced several millions of high quality sexreversed tilapia fry, many others showed interest. At least four hatcheries came into operation between 2006 and 2008 in mid-southern part of Bangladesh. After this, proliferation of monosex hatcheries and cage culture started in many parts of Bangladesh. About 3,500 cages are in operation now in Chandpur along the Dakatia River, 500 cages in Laxmipur along the Meghna River. Culture involves stocking of 37-40 sex-reversed tilapia fry of 20-25 g size per m. Fish grow around 400 g in 6-7 months giving around 15kg/m productivity when fed floating feeds. Mortality remains <5% and FCR around 1.75. Altogether, these cages are producing at least 3,200 metric tons of tilapia annually. At least 600 people including 5% women are working in the cages. Four feed producing companies are providing 6,000 MT of floating feed annually. Probably, as a result of intensification and contamination from other countries, farmers as in other countries, are facing disease problem which is threatening the tilapia industry. A solution has to be explored.
