Ukuran pertama kali ikan matang gonad untuk jantan 41,5 cm dan betina 40,1 cm. Ukuran ikan yang tertangkap sebagian besar belum layak untuk ditangkap karena 1/2 L∞ > L 50% < Lm. Nilai IKG jantan berkisar 0,08 – 3,58 dan betina 0,13 – 4,35. KM 30 – 50 GT memiliki nilai CPUE tertinggi yaitu sebesar 2.702,17 kg/trip. Usaha penangkapan PMT lebih menguntungkan karena pendapatan harian nelayan PMT lebih besar dibandingkan dengan nelayan KM. Rencana Pengelolaan yang disarankan yaitu pengaturan ukuran ikan layak tangkap, pengaturan mata jaring mini purse seine (> 6 cm), gill net (>10 cm) dan ukuran mata pancing (<5), pengendalian dan pemantauan jumlah armada penangkapan dan alat tangkap yang beroperasi, serta pengaturan musim dan daerah penangkapan.
