STOCK STUDY OF RED SNAPPER (LUTJANUS MALABARICUS) FOR SUSTAINABLE MANAGEMENT AT TPI TASIK AGUNG II OF REMBANG REGENCY, INDONESIA

Abstract

Red snapper (Lutjanus spp.) is one of the leading commodities in FMA 712. According to the Fisheries and Marine Service of Rembang Regency in 2020, the trend of Red Snapper production has always increased over the last 5 years (2016-2020). The existing trend of Red Snapper fishery production is inversely proportional to the state of potential demersal fish resources in WPP 712 which are already fully exploited. Fish resources that are open access must always be monitored and their utilization regulated. The purpose of this study was to examine the condition of the red snapper stock in the waters of WPP 712 which landed in Rembang. This research was conducted in June 2022. The data analysis consisted of: the relationship between length and weight, condition factors, exploitation rate, and surplus production model. The results showed that red snapper had a negative allometric growth pattern. The natural mortality value (M) is 1.43, the fishing mortality value (F) is 0.74. The exploitation rate of red snapper has exceeded the optimum exploitation rate so that the red snapper in FMA 712 is thought to have overfished. Management that can be suggested is through limitation of fishing units and selectivity of fishing gear.
