Zusammenfassung: | As the member of Commission for The Conservation of Southern Bluefin Tuna (CCSBT), Indonesia shall follow the quota measure of SBT fishing that has determined Therefore, good management and rules were needed for SBT exploitation in Indonesia in order to align with measures and international regulation that has agreed by Indonesia as part of CCSBT. The objectives of this research were to determine catch composition, productivity of Indonesia tuna longline fisheries especially that doing SBT fishing activity; to estimates fishing season; and to determine mean size at capture of SBT in Indonesia. The result showed that catch composition of tuna longline has the smallest percentage value for the type of SBT. Trend of SBT production percentage was increase every year in 19 years period. Fishing season of SBT in Indonesia was in August to March that assumed same with nursery season of SBT. Mean size at capture of SBT (L sub(50%))was 145 cm FL This size that assumed has feasible to be caught or has beyond spawning period.Original Abstract: Sebagai anggota Commission for the Conseroation of Southern Bluifin Tuna (CCSBT), Indonesia hams mengikuti aturan kuota penangkapan tuna sirip biru selatan (southern bluifin tuna/SBT) yang telah ditetapkan. Untuk itu diperlukan pengaturan dan tata kelola yang baik dalam pemanfaatan SBT di Indonesia agar selaras dengan kaidah dan aturan-aturan intemasional yang telah disepakati Indonesia sebagai bagian dari CCSBT. Penelitian ini bertujuan untuk menghitung komposisi hasil tangkapan dan tingkat produktivitas armada tuna long line Indonesia khususnya yang melakukan aktivitas penangkapan SBT menduga bulan musim penangkapan dan menghitung ukuran rata-rata tertangkap SBT hasil tangkapan tuna long line Indonesia. Hasil penelitian menunjukkan jenis SBT memiliki nilai persentase terkecil dari komposisi hasil tangkapan tuna long line di Indonesia. Namun demikian, tren persentase produksi SBT memiliki keeenderungan meningkat dari tahun ke tahun seiring dengan meningkatnya tren produktivitas tuna long line. Musim penangkapan SBT di Indonesia terjadi pada bulan Agustus-Maret, yang diduga juga merupakan musim pemijahan tuna sirip bim selatan. Ukuran rata-rata tertangkap SBT (L sub(50%)) adalah berukuran 145 cm FL sehingga bisa dikategorikan sudah layak tangkap karena telah melalui fase ikan melakukan pemijahan atau recrutment. |
