摘要：The study of Purple-spotted bigeye resources management especially in Batang waters is still minimal, therefore intensive attention and proper management is needed. The objective of this study is to determine the utilization of Purple-spotted bigeye resources in Batang waters. The research was conducted in March – July 2020. Bioeconomic analysis was carried out using the Gordon-Schaefer formula to analyze the fishery production trends in the form of time series. The result shows that the sustainable yield (EMSY) of Purple-spotted bigeye is 2473.16 tons year-1 with optimum effort (FMSY) 2075 trips year-1. The maximum production at maximum economic yield (EMEY) level is 2225.94 tons year-1 with effort (FMEY) 1366 trips year-1. Open access condition of Purple-spotted bigeye will be achieved when the number of fishing effort (EOA) reaches 2732 units with production (EOA) of 2184.03 tons year-1. The production and fishing effort in actual condition showed that the utilization of Purple-spotted bigeye can still be optimized, but it should be done carefully and wisely without exceeding the optimum catch limit to prevent overfishing.
