Abstract
Indo-Pacific king mackerel has been long fished by traditional and modern fishers. The fish is a catch target species with high economic value in local and export markets. The fishing efforts for the fish have been increasingly intensive. The management for which is still lacking. The concern is, continuous exploitation will make indo-pacific mackerel stock susceptible. The fish condition should be measured based on productivity and susceptibility parameters using productivity susceptibility analysis (PSA). The study aimed to analyze the sustainability of Indo-Pacific king mackerel and other species caught by gillnet and purse seine in IFMA 711 based on productivity and susceptibility scenarios. The study analyzed Indo-Pacific king mackerel and other species, i.e. whitefin wolf-herring, narrow-barred Spanish mackerel, longtail tuna, eastern little tuna, and bigeye scad. The results of the analysis suggest that Indo-Pacific king mackerel and whitefin wolf-herring were of moderate productivity and susceptibility, narrow-barred Spanish mackerel and longtail tuna were of high productivity and low susceptibility, and eastern little tuna and bigeye scad were of low productivity and high susceptibility, putting both at high risk from fishing activities. Also, the data quality of Indo-Pacific king mackerel was moderate, while the data quality of whitefin wolf-herring was the worst. Therefore, it is necessary to improve the quality and quantity of the data and scientific information on whitefin wolf-hearing in further studies.
