Salah satu masalah yang dihadapi dalam pemanfaatan sumberdaya ikan adalah kurang selektifnya berbagai jenis alat tangkap yang digunakan oleh para nelayan. Akibatnya adalah tertangkapnya ikan-ikan yang bukan menjadi tujuan penangkapan (bycatch) yang dalam prakteknya sebagian besar ikan-ikan tersebut dibuang ke laut (discarded catch). Penelitian ini bertujuan untuk mengidentifikasi dan menginventarisasi komposisi jenis dan ukuran ikan hasil tangkapandari alat tangkap bagan perahu dan bagan tancap.Lokasi penelitian di Kelurahan Oesapa sebagai sentra pemukiman nelayan bagan perahu danbagan tancap di Kota Kupang dan di Perairan Teluk Kupang.Penelitian ini dilakukan menggunakan metode survei dengan obyek penelitian yaitu: fakta, proses, histori, persepsi tentang perikanan bagan perahu, komposisi jenis dan ukuran ikan tangkapan yang meliputi identifikasi hasil tangkapan, berat (kilogram), jumlah (ekor), panjang cagak (fork length), keliling maksimum (maximum girth), dan lebar badan ikan. Cara mengukur panjang baku pada penelitian ini yaitu jarak garis lurus antara ujung bagian kepala yang paling depan (biasanya ujung salah satu dari rahang yang terdepan) sampai ke pelipatan pangkal sirip ekor.Hasil menunjukkan bahwa jenis ikan yang dominan tertangkap pada bagan perahu adalah ikan teri, peperek dan kembung, sedangkan pada bagan tancap ikan peperek, teri dan tembang. One of the problems faced in using fish resources is the lack of selectivity of various types of fishing gear used by fishermen. The result is the catch of fish which is not the purpose of arrest(bycatch) which in practice most of the fish are discarded catch. This study aims to identify and inventory the type and size offish catches (boat lift net and fix lift net). Research location in Oesapa village in Kupang City in Kupang Bay. This research was conducted by survey method with research object that is: fact, process, history, perception of fishery boat lift net, species composition and size of fish catch including identification of catch, weight (kilogram), number (tail), length of fork length, maximum girth, and fish body width, mesh size.

Milkfish is an important commodity with high economical value, delicious meat, relatively reachable price, disease attack resistance, and non-cannibalistic, which can live in high stocking density and can be cultured in polyculture system with other animals and plants, therefore encourages many fish farmers to perform this culture system. This study was performed in experimental method with three treatments and three replications of different water exchange systems, namely, once in 2 days (Tank A), everyday (Tank B), and everyday water circulation (Tank C). Milkfish seeds with average initial weight of 11.37 ± 0.97 g and average initial length of 6.08 ± 0.78 cm were maintained for 45 days at different water exchange systems and fed with Megami pellet feed. The results showed that Tank C with water circulation performed everyday was the best treatment to improve the milkfish seed production with 100% survival rate, 1.77±0.01%.day-1 specific growth rate, 4370.37 ±1.28μm.day-1 absolute length growth, and 31.91 ±2.82% feed efficiency.
