ABSTRACT

Research on size structure of skipjack captured by pole and line fishermen inside and outside of fish aggregation device area has been done from January until June 2016 in Gulf of Bone waters. The objectives of research were to analysis of size structure, percentage of suitable length to catch, and yield composition of pole and line with FAD and without FAD. Size structure was analyzed by method of Bhattacharya, percentage of suitable length to catch by method of Mallawa, and catch composition by column diagram. The result showed that the size structure was different between skipjacks captured by pole and line with FAD and without FAD, where skipjack captured by pole and line with FAD dominated by small fishes while skipjack captured by pole and line without FAD dominated by large fishes, percentage of suitable length to catch of skipjack captured by pole and line without FAD was high than pole and line with FAD while both were still low, yields of pole and line with FAD and pole and line without FAD consist of skipjacks and yellow fin tuna where skipjack was dominant for all trip.
