Bycatch Composition and Ecological Status of Trap and Gillnet Blue Swimming Crab Fisheries in Bone Gulf, Southeast Sulawesi, Indonesia
In Indonesia, bycatch is currently among the problems of crab fisheries apart from overfishing due to limited data. Therefore, this study aimed to determine the species composition, proportion and ecological status of the bycatch fishery of trap and crabs gillnet in the southeastern Bone Gulf. The sampling was monthly carried out, and the samples obtained were grouped into four; namely, fish, crustaceans, molluscs, and echinoderms. The composition of the bycatch of trap and gillnet crab fisheries was dominated by crustacean groups. Based on the Mann-Whitney test, the proportion of crab trap and gillnet bycatch was significantly different (P<0.05). Furthermore, the species composition of the crab trap fisheries bycatch consisted of 29 and 31 species of old and new traps, respectively, as well as 52 species of gillnet fishery bycatch. The ecological status of the bycatch diversity of the trap fishery is low, while the crab gillnet fishery is moderate. This showed that crab gillnets have lower ecological stress than crab traps.
