At each hauling, twenty fish from each species were taken randomly measured their fork lengths. Catches during the study consisted of six species; namely skipjack (Katsuwonus pelamis), yellow fin tuna (Thunnus albacores), little tuna (Auxis thazard), scad mackerel (Decapteru smacarellus), rainbow runner (Elagatis bipinnulata), oceanic trigger fish (Canthidermis maculata) and trevally (Selaroides leptolepis).

ABSTRAKAlat tangkap purse seine dianggap paling produktif untuk menangkap ikan pelagis, sehingga banyak kapal purse seine yang berpangkalan di Pelabuhan Perikanan Samudera Bitung beroperasi di Wilayah Pengelolaan Perikanan RI (WPP) 715 Laut Maluku. Beberapa issue menyebutkan bahwa hasil tangkapan purse seine terutama di sekitar rumpon tergolong ikan-ikan yang belum dewasa. Oleh karena itu, perlu mempelajari keragaman dan distribusi hasil tangkapan purse seine di wilaya tersebut. Pengumpulam data dilakukan dengan cara pengamatan langsung dan partisifasi aktif dilapangan, wawancara dengan anak buah kapal KM Grasia 04. Pada setiap kali hauling, diambil secara acak 20 ekor ikan sampel setiap jenis dan mengukur panjang bakunya. Hasil tangkapan selama penelitian adalah 6 jenis ikan; yaitu ikan cakalang (Katsuwonuspelamis), madidihang (Thunnusalbacores), tongkol (Auxis thazard), malalugis (Decapterus macarellus), sunglir (Elagatis bipinnulata), tato batang (Canthidermis maculata) dan selar (Selaroides leptolepis).Tetapi hasil tangkapan yang dominan pada setiap hauling adalah cakalang, madidihang, tongkol dan malalugis.
