HUBUNGAN PANJANG-BERAT, KEBIASAAN MAKANAN, DAN REPRODUKSI IKAN KAKAP MERAH (Lutjanus gibbus: Famli LUTJANIDAE) DI PERAIRAN SELATAN BANTEN
Abstract
Ikan kakap merah (L. gibbus) adalah jenis ikan demersal dari famili Lutjanidae yang bernilai ekonomis penting dan banyak tertangkap di Indonesia. Informasi tentang kebiasaan makan dan aspek reproduksi ikan kakap merah di Indonesia masih relatif sedikit. Selain itu, telah terjadi penurunan stok ikan kakap merah di Selatan Banten selama 6 tahun terakhir (2008-2013). Penelitian ini bertujuan untuk mengkaji hubungan panjang-berat, kebiasaan makan dan reproduksi ikan kakap merah.. Penelitian dilakukan selama 3 tahun (2013, 2015 dan 2016). Ikan contoh diambil dari hasil penangkapan ikan oleh para nelayan dengan alat tangkap pancing rawai dasar dan pancing ulur dengan mata pancing no 7-10 yang didaratkan di Binuangeun-Banten. Analisis fekunditas dilakukan di Laboratorium dengan metode gravimetrik. Hasil penelitian menunjukkan bahwa ikan kakap merah jantan memiliki ukuran lebih panjang dibandingkan ikan betina, pola pertumbuhannya bersifat isometrik. Kebiasaan makan ikan kakap merah tergolong ikan karnivora dimana makanan utamanya adalah ikan dan kepiting (Portunidae). Nisbah kelamin jantan dan betina tidak seimbang yaitu 1: 1.53. Fekunditas berkisar 14.050–596.243 butir dengan rata-rata 170 869 butir, diameter telur berkisar 0,03–1,02 mm dan pola pemijahannya bersifat salin sebagian (partial spawner).
The humpback red snapper (Lutjanus gibbus) is the family of lutjanidae which has important economic value in Indonesian capture fisheries. In addition, there has been a sharp decline on the population of humpback red snapper in the Southern part of Banten during the last 6 years (2008-2013). This study aims to examine the growth function, food habits and reproductive biology of L. gibbus in the Southern part of Banten Waters. Fish samples were collected for 3 years (2013, 2015 and 2016) both from fishing ground and landing places in Binuangeun-Banten, caught by handline and bottom longline. The fecundity analysis was performed in Laboratory by gravimetric method. The results showed that the average size of males of humpback red snapper was longer than females with the growth pattern was isometric. The food habits of humpback red snapper was classified as carnivorous fish in which the main food item consist of fish and crab (Portunidae). Sex ratio of males and females were unbalance by 1: 1.53. The fecundity ranges from 14.050-596.243 eggs with an average of 170.869 eggs. The humpback red snapper found as partial spawner which eggs diameter ranged from 0,03 to 1,02 mm.
