The performance of traditional fishing technologies of narrow barred Spanish mackerel (Scomberomorus commerson) in Bone Bay waters, South Sulawesi, Indonesia

Abstract

Narrow barred Spanish mackerel is a high-value pelagic fish and is mostly caught in Bone Bay waters. These fish can be caught using purse seines, drift gill nets, lift net and hand lines, but the most catches are in drift gill nets and hand lines. This study aims to compare the performance of drift gill nets and hand line technologies. Biological, technical, social, economic and legal data were collected from 2018 to 2020 through direct field observations and interviews. Performance according to the four aspects and the combination of all aspects of the two fishing gear were analyzed using the Mangkusubroto Scoring method. Based on the biological and technical aspects the performance of the hand line was better than the drift gill nets, while on the contrary, based on the economic and social aspects, the performance of gill nets was better than the hand lines. Based on legal and institutional aspects, the two technologies do not show any differences. Although there are differences in the performance of the biological, technical, social and economic aspects, the performance of the two technologies is classified as good.
