Abstract

Cantrang merupakan alat tangkap yang berkembang dengan pesat sebagai teknologi penangkapan ikan pengganti trawl, dimana trawl telah dilarang beroperasi di wilayah Indonesia sejak diterbitkannya Keppres No. 39 tahun 1980. Cantrang merupakan jenis alat tangkap yang dominan digunakan oleh nelayan yang berbasis di Pelabuhan Perikanan Nusantara (PPN) Brondong, Kabupaten Lamongan, Jawa Timur. Penelitian ini bertujuan untuk mengidentifikasi spesifikasi alat tangkap cantrang, konstruksi dan hasil tangkapan cantrang. Berdasarkan hasil penelitian cantrang mendominasi sebesar 75% alat penangkapan ikan di PPN Brondong, ukuran rata-rata kapal cantrang di PPN Brondong dengan panjang (Ldek), lebar (B) dan dalam (D) adalah 14,08 m, 6,03 m, dan 2,24 m. Selain itu, jenis hasil tangkapan ikan dengan menggunakan alat penangkap ikan cantrang didominasi oleh jenis-jenis ikan demersal. Kata kunci: spesifikasi cantrang, ukuran cantrang, hasil tangkapan

Abstract

Bullet tuna (A. rochei) is a species of pelagic fish that holds significant economic importance and serves as a source of livelihood for fisherman. The purpose of this study was to determine length-weight relationship of bullet tuna (A. rochei) landed at Kendari Ocean Fishing Port. Sampling of bullet tuna (A. rochei) using random sampling method. The analysis used in this study is linear regression analysis. The results of the study indicate that 600 rochei tuna (A. rochei) caught ranged in length from 152 to 265 mm and weighed between 70 and 285 grams. The length and weight of bluefin tuna (A. rochei) were strongly correlated (r = 0.68) with a negative allometric growth pattern (b = 2.0175). These results suggest that the rate of length growth is more dominant than the rate of weight gain in fish. The growth patterns obtained from the results of the length-weight relationship research are crucial for sustainable fisheries management, such as regulating the selectivity of fishing gear.
