Pendugaan Stok Ikan Tuna Mata Besar (Thunnus Obesus) Yang Didaratkan Di Pelabuhan Perikanan Samudera Bungus Provinsi Sumatera Barat

---

This study aims to estimate the stock of bigeye tuna at the Bungus Oceanic Fishing Port (PPS Bungus) over a six-year period (2018–2023) using surplus production models (Schaefer and Fox). The methods used include observation, primary data collection through interviews, and secondary data from logbooks and annual reports of PPS Bungus. The analysis results show that the Fox model is more suitable for estimating the stock of bigeye tuna, with a maximum sustainable yield (MSY) of 73,380.7 kg/year and an optimum fishing effort (F-opt) of 120 trips/year. The allowable catch (JTB) was 58,704 kg/year with a fishing effort (fJTB) of 96 trips/year. The average utilization rate of bigeye tuna was 74.85%, categorized as fully-exploited, indicating a balance where the catch has reached the sustainability threshold. The fishing effort rate for bigeye tuna was 40.9152%, still below the optimum fishing effort value of 49 trips out of 120 trips (F-opt). These findings highlight the importance of maintaining stable fishing efforts each year to support the sustainability of bigeye tuna resources at PPS Bungus.
