摘要

萨利赫湾是西努沙登加拉的一个海湾，被用作石斑鱼渔场。然而，在以往的产卵潜力比研究中，一些石斑鱼种类在萨利赫湾被过度捕捞。利用单位努力渔获量法(CPUE)估算了沙雷湾渔场石斑鱼利用状况及时空捕捞强度。利用鱼类上岸数据和萨利赫湾渔场石斑鱼的地理参考资料收集数据。本研究采用了描述性分析、单位努力渔获量和时空分析等方法。结果表明:单位渔获量对产量有正向影响，沙雷湾海域石斑鱼捕捞量呈增加趋势;2016年CPUE值为2.82 kg/趟，2020年增至3.99 kg/趟。在空间和时间上，渔民在梁岛、登浦岛、利班岛、塔卡努沙普渡岛和拉吉岛等小岛附近捕捞石斑鱼。石斑鱼捕捞强度最高的海域是拉吉岛、梁岛和恩加利岛。关键词:单位努力渔获量，渔场，石斑鱼，萨利赫湾

PEMETAAN SPASIAL DAN TEMPORAL STATUS PEMANFAATAN IKAN KERAPU DI PERAIRAN TELUK SALEH, NUSA TENGGARA BARAT

The Saleh Bay is one of the bays in West Nusa Tenggara utilized as the grouper fishing ground. However, in the previous spawning potential ratio study, some grouper species have been overexploited in Saleh Bay. This study aimed to estimate the status of grouper utilization with a catch per unit effort (CPUE) approach and the spatio-temporal fishing intensity of grouper in fishing grounds in Saleh Bay. Data were gathered using the fish landing data and geo-reference of fishing ground grouper in Saleh Bay. This study used several methods: descriptive analysis, catch per unit effort, and spatial-temporal analysis. The result showed that the catch unit effort positively impacts production, with the increasing trend of grouper fishing in Saleh Bay waters. The CPUE value in 2016 was 2.82 kg/trip, while in 2020, it increased to 3.99 kg/trip. Spatially and temporally, fishers caught grouper around small islands such as Liang Island, Dempu Island, Lipan Island, Takat Nusa Pudu, and Rakit Island. The highest intensity of grouper fishing around the marine protected area, namely Rakit Island, Liang Island, and Ngali Island. Keywords: catch per unit effort, fishing ground, grouper, Saleh Bay
