Abstract
The purpose of this study was to determine the species composition of the bottom longline^s catch and describe the frequency of occurrence of fish species based on fishing trips of the bottom longline. This research was conducted from February to March 2019 on Makarangana Island, Sabalana Village, Liukang Tangaya District, Pangkep Regency, South Sulawesi Province. The data collection method is used in the case study method by directly following the fishing operations of the bottom longline for 30 fishing trips. The results showed the composition of the type of fish dominantly caught with a longline that operates in the waters of Makarangana Island was giant trevally (Caranx ignobilis) 88.71 kg that was 20%, Crimson Snapper Fish (Lutjanus erythropterus) 71.91 kg that was 16%, Snout Lustam Fish (Snout Fish) (20%) Lethrinus microdon) 59.82 kg which was 13%. However, when viewed from the catch aspect, the production of fish species of the Letrinidae and Lutjanidae families were more than that of the giant trevally (Caranx ignobilis) species. The frequency of emergence of catch fish that was dominantly caught with a longline that operated in the waters of Makarangana Island was a snout fish species (Letrinus microdon) 53.3%, Crimson Snapper fish (Lutjanus erythropterus) 43.3% and Red Snapper (Lutjanus malabaricus) 40.0 %. The highest fishing productivity of the bottom longline operating in the waters of Makarangana Island was 0.13 fish/hook. Meanwhile, the lowest fishing productivity was 0.03 fish/hook.
