ABSTRAK

Alat 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. Hasil analisis menunjukan bahwa sebagian besar hasil tangkapan kapal purse seine Grasia 04 di perairan Laut Maluku belum layak tangkap.
