Abstract: The utilization status of crimson snapper stock in the Northern Java Sea (FMA 712) has reached optimum, tending to be over-exploited. This study aims to evaluate the stock status of crimson snapper (Lutjanus erythropterus) in FMA 712, especially in the northern waters of East Java. This research utilized catch data from the Brondong fishing port. The stratified random sampling method was utilized to collect samples at the research site. The findings indicate that the growth pattern of L. erythropterus exhibits a tendency towards negative allometry, with fishing mortality (F = 1.55) exceeding natural mortality (M = 0.89). The exploitation rate has reached a status of ‘fully exploited’ (E = 0.6). The Gonad Maturity Level (GML) of the catch is predominantly composed of GML I and GML II, suggesting that the majority of the captured fish have not yet spawned. It relates to the predominance of cantrang and jaring tarik berkantong, which capture fish of juvenile size. Thus, the Spawning Potential Ratio (SPR) parameter indicates it is ‘fully exploited’ (SPR = 0.22), i.e., the utilization rate has exceeded the limit of natural capacity for recruitment. This SPR value confirms: the utilization rate parameter (E), the fact that catch sizes tend to get smaller, and the results of previous studies in FMA 712. It is imperative to regulate the fishing efforts targeting the crimson snapper, as well as the deployment of cantrang and jaring tarik berkantong, which pose potential threats to the sustainability of this fishery.
