Potensi Lestari Ikan Kembung (Rastrellinger sp.) Dengan Alat Tangkap Purse Seine di Pelabuhan Perikanan Samudera Belawan Provinsi Sumatera Utara

Abstract

Mackerel (Rastrelliger sp.) is one of the fish that belongs to small pelagic fish. Mackerel is found in coastal and offshore waters and is generally widely distributed in the central part of Indonesia.The purpose of this study is to determine the sustainable potential and utilization rate of mackerel (Rastrelliger sp.) . This research was carried out in July – August 2024. This research method uses the surplus production method, namely Catch Per Effort (CPUE) and Estimation of Sustainable Potential (MSY). Sustainable Potential was analyzed using the Surplus Production Model with the Fox model. The results showed that the average catch value per unit effort was 0.14 tons/trip. The maximum sustainable potential of mackerel is 18200.22 tons/year with optimal fishing efforts (fopt) of 41011.84 trips. The average utilization rate of 1.5% of the MSY value is categorized as low (underfishing), while the value of the allowed catch is 14560.17 tons/year. Overall, mackerel fishing can still be improved to get more optimal results, but not exceeding the MSY limit that has been determined.
