This study is a baseline study that aims to assess functional diversity and biomass of herbivorous fish as indicators of resilience potential of coral reef ecosystems in Doreri Bay, Manokwari Regency. Belt transect method was applied in collecting fish species data, number, and length of fish. The functional diversity of herbivorous fish groups was calculated as the number of functional groups present at each observation site. The average length of the fish size class was applied to calculate biomass using the length-weight relationship formula (L-W), which is W = a × L, where a and b are the parameter values for each species obtained from FishBase. Biomass was calculated as an estimate of the total weight of herbivorous fishes, divided by the area covered by transects, then converted to units of grams per square meter (...

The method used is descriptive method. The production of mud crabs (Scylla sp.) Was obtained based on data from the fishermen of the village of Banjar Ausoy for four months obtained a total of 21869.6 kg. The highest catch of mud crabs in January was 7861.7 kg and the lowest in April was 3176.5 kg. A total of 24 fishermen and 7 collectors, found 640 individuals (folding traps) and 545 individuals (circular traps) such as (S. tranquebarica) and (S. olivacea).

This study aims to provide an overview of the economic impact of flying egg fishing and the marketing channels of these flying fish eggs. Data collection was carried out in August and September 2017 in the coastal areas of Fak Fak and the Fak Fak Fishing Base and several other landing areas. Interview and questionnaire techniques used for data collection also used secondary data from various sources and previous research. The data collected was analyzed descriptively and displayed in graphical form and percentage to reveal facts based on field information. The results showed that in 2017 the production of flying fish eggs per ship ranged from 270 - 1,575 kg, with an average value of IDR 307,446,154. The fish egg marketing channel in Fakfak Reg...

The aims of this study were to analyse and describe the characteristics of flyingfish habitat, based on oceanographic conditions and eggs catches, and to visualize the variability in spatial and temporal patterns of predicted potential spawning grounds. The research was conducted in Fak-Fak and adjacent seas in the Indonesian Fisheries Area WPP 715, from 130°−134° E and 2°S−5° S. Data were collected during 2018 for selected months: June, July, August and September. Remote sensing data used in this study included chlorophyll-a concentration (Chl-a) OCI-Algorithm, Sea Surface Temperature (SST) 11μ daytime, Absolute Dynamic Topography (ADT), Significant Wave Height and Ocean Surface Current (meridian and zonal components). Fishery data were collected from fishermen’s GPS units, and through participatory mapping. Based ...
