<![CDATA[Ikan sembilang (Plotosus canius) merupakan salah satu sumber daya ikan di perairan estuaria, Kabupaten Banyuasin, Sumatera Selatan. Penelitian beberapa aspek biologi ikan sembilang dilakukan pada bulanApril sampai Juli 2007. Contoh ikan diperoleh dari nelayan yang menangkap dengan alat tangkap belad dan rawai dasar. Hasil penelitian ini menunjukan ratio kelamin jantan terhadap betina yaitu 1:2. Organisme yang ditemukan dalamsaluran pencernaan terdiri atas lima jenis yaitu potongan kepiting, udang, ikan, cacing, dan keong, sehingga ikan sembilang dapat digolongkan sebagai ikan karnivora. Pola pertumbuhan ikan sembilang bersifat isometrik (b=3), berartipertumbuhan panjang seiring dengan pertumbuhan bobot. Kelompok ukuran panjang ikan sembilang tertangkapdidominansi oleh ukuran panjang antara 25,1-30,1 cm. Eeltailed catfish (Plotasus canius) is one of the fish resources in the estuarine waters of Banyuasin South Sumatera. Research on some biological aspect of Plotosus canius was conducted from April to July 2007. Fishes were caught by fishermen using barrier traps and bottom long line. The results show that the sex ratio of male to female was 1:2. Organisms found in the digestive tract consists of five types crabs, shrimp, fish, worms, and snails. Thus eeltailed catfish can be classified as a carnivorous fish. The constant (=b) of length weight relationship of Plotosus canius was 3 (t-test) suggesting this species was length increment as fast as weight increment. Based on total length size group measured, fish dominontly caught in length of 25.1-30.1 cm.]]>
