Analisis Produksi Penangkapan Ikan Tuna Mata Besar (Thunnus Obsesus) di WPPNRI 572 yang Didaratkan di Pelabuhan Perikanan Samudera (PPS) Nizam Zachman Jakarta

Indonesia's marine fisheries face sustainability challenges, particularly for bigeye tuna (Thunnus obesus) from WPPNRI 572 landed at PPS Nizam Zachman Jakarta, where increasing capture trends risk overexploitation. This study aims to analyze catch production, CPUE, MSY, exploitation rate, and allowable catch (JTB) using the Schaefer model. Employing descriptive quantitative methods, the population comprised all production data (2014-2023), with total sampling of 81,375.22 tons from 12,006 standardized trips. Instruments included statistical reports and Excel for Fishing Power Index standardization and linear regression (). Results showed purse seine dominating catches (55.32%), MSY at 145.88 tons, Emsy 152 trips, JTB 116.70 tons, and exploitation rate 79% indicating fully-exploited status with declining CPUE trends. In conclusion, immediate quota implementation through PIT is essential to prevent overfishing while maintaining economic benefits.
