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
Ikan ekor kuning (Caesio cuning) merupakan hasil tangkapan yang dominan ditangkap oleh nelayan Karimunjawa. Tingkat pemanfaatan ikan ekor kuning cukup tinggi sehingga perlu adanya pengaturan dalam pengelolaan agar sumberdaya ikan ekor kuning tetap terjaga. Penelitian ini bertujuan untuk mengevaluasi status sumberdaya ikan ekor kuning pada musim peralihan bulan Maret-April 2018. Metode yang digunakan adalah teknik Length-Based Spawning Potential Ratio (LB-SPR). Hasil penelitian memperlihatkan bahwa kondisi stok sumberdaya ikan ekor kuning pada bulan Maret–April 2018 (musim peralihan I) under exploited dengan nilai kematian diakibatkan penangkapan (F/M) sebesar 1,44, Spawning Potential Ratio (SPR) 0,50 dan rata-rata ukuran ikan yang tertangkap lebih besar dari nilai panjang pertama kali matang gonad (SL50>Lm) sehingga penambahan upaya sebesar 10% pada musim peralihan masih memungkinkan. Pada penelitian sebelumnya pada bulan Januari–Februari 2017 (musim barat) kondisinya telah tereksploitasi secara berlebih dengan nilai kematian diakibatkan penangkapan (F/M) 2,75, Spawning Potential Ratio (SPR) 0,18 dan rata-rata ukuran ikan yang tertangkap lebih kecil dari nilai panjang pertama kali matang gonad SL50<Lm. Oleh karena itu, pengaturan terkait jumlah penangkapan perlu diatur sesuai musim penangkapan agar terciptanya perikanan ekor kuning yang berkelanjutan. Kata kunci: alat tangkap, Karimunjawa dan spawning potential ratio
