      Abstract
      Mini purse seine merupakan alat tangkap ikan dominan yang berbasis di Pelabuhan Perikanan (PPN) Sungailiat. Penggunaan alat tangkap secara intensif berpotensi mempengaruhi ikan target dan keseimbangan rantai makanan. Penelitian ini bertujuan: (1) mendeskripsikan perikanan mini purse seine yang berbasis di PPN Sungailiat, Bangka; (2) menganalisis parameter biologi ikan target tangkapan mini purse seine; (3) dan mengevaluasi dampak perikanan mini purse seine terhadap ikan target berupa ukuran layak tangkap dan keseimbangan rantai makanan hasil tangkapan. Metode yang digunakan dalam penelitian ini adalah metode survei dan observasi. Hasil penelitian menunjukkan bahwa penggunaan alat tangkap mini purse seine di perairan sekitar PPN Sungailiat cenderung meningkat dan produksi hasil tangkapannya menurun. Ikan target tangkapan mini purse seine adalah ikan siro (Amblygaster sirm), ikan selar bentong (Selar crumenophthalmus) dan ikan selar kuning (Selaroides leptolepis). Ikan siro memiliki pola pertumbuhan allometrik positif dengan 96% tangkapan berukuran layak tangkap, sementara ikan selar bentong dan ikan selar kuning bersifat allometrik negatif dengan masing-masing sebesar 100% dan 89,39% tangkapan berukuran layak tangkap. Hasil tangkapan didominasi oleh kelompok predator tingkat rendah. Di samping itu kelompok ikan top predator juga tertangkap oleh mini purse seine sebanyak 24%, sehingga dalam jangka panjang berpotensi mengancam keseimbangan rantai makanan sumberdaya ikan di lokasi tersebut.
       
      Mini purse seine is the dominant fishing gear used by fishers based at the Sungailiat Nusantara Fishing Port (PPN). Intensive use of this fishing gear can potentially affect target fish and trophic levels of fish resources. This research aims to: (1) describe the mini purse seine fishery based at PPN Sungailiat, Bangka; (2) analyze the biologycal parameters target fish caught by mini purse seine; (3) evaluate the impact of mini purse seine fishery on allowable catch size of target fish and trophic levels of the catch. The methods employed in this study were survey and observation. The results of this study indicate that the number of mini purse seine used in the fishing grounds based at the PPN Sungailiat has shown an increasing trend while the catch has decreased. The target fish caught by mini purse seine are predominantly spotted sardinella (Amblygaster sirm), bigeye scad (Selar crumenophthalamus), and yellowstripe scad (Selaroides leptolepis). The growth pattern of spotted sardinella had positive allometric with 96% of the catch was higher than the allowable catch size. In comparison, bigeye scad and yellowstripe scad demonstrated negative allometric growth patterns with 100% and 89.39% of the catch being the allowable catch size, respectively. Low trophic levels of predator groups dominated the catch. Additionally, top predator fish groups were also caught by mini purse seine with 24%, potentially threatening the long-term balance of the marine food web in the location.
