      Ikan kembung lelaki merupakan salah satu ikan pelagis kecil yang memiliki nilai ekonomis penting di Teluk Banten dan merupakan ikan tangkapan dominan yang didaratkan di PPN Karangantu. Dikhawatirkan populasi ikan ini akan menurun akibat kegiatan penangkapan berlebihan yang dilakukan terus menerus. Oleh sebab itu dilakukan penelitian untuk mengkaji stok ikan kembung lelaki di Teluk Banten guna menentukan alternatif pengelolaan ikan tersebut yang lebih tepat dan berkelanjutan. Penelitian ini dilakukan dari bulan Mei-Agustus 2012 dengan interval waktu pengambilan contoh setiap ± 13 hari. Data primer yang dikumpulkan adalah panjang total, bobot basah, TKG, jenis kelamin, dan bobot gonad melalui pembedahan ikan. Ikan kembung lelaki yang banyak tertangkap memiliki TKG I dan TKG II. Pola pertumbuhan nya bersifat allometrik negatif dan ukuran pertama kali ikan kembung lelaki matang gonad mencapai 216 mm.
