Study of demersal fish resources for sustainability of capture fisheries in Pangandaran Beach, Indonesia

Fisheries Engineering

Fisheries resource stock estimation is important information used to determine the appropriate management for the sustainability of fish resources. Demersal fish as a commodity with its various species and abundant numbers in the Indonesian waters is an important object to be researched. The method used in this research is descriptive quantitative. Primary data were obtained by making direct observations to the research location and interviews with fishermen and Pangandaran fishery port employees. Information obtained from the interview results in the form and size of the fishing unit, the fishing area, the number of operating trips for each fishing gear. The secondary data needed in this research is periodic data (time series) of the production of catches at TPI Pangandaran for the last 5 (five) years. Based on the research results, the main commodities of demersal fish in Pangandaran Beach are Trichiurus lepturus, Johnius trachycephalus, Saurida undosquamis, Pampus argenteus, Arius thalassinus, Chirocentrus dorab, Lutjanus bitaeniatus, Parastromateus niger, and Geres punctatus. The fishing gear that catches demersal fish in Pangandaran is the gill net, trammel net, longline, mini bottom trawl, beach seine and lift net. The CPUE (catch-per-unit-effort) value of demersal fish is 0.072 tonnes per trip with a total allowable catch of 27.51 tonnes, MSY 34.39 tonnes and effort of 1200 trips per year. Basically, from these data it can be analyzed that the demersal fish production which is currently being utilized has experienced overfishing.
