Preliminary study on the effect on growth and survival rate of stocking density of big fin squid, Sepioteuthis lessoniana raised in floating net cages

英语. The study was conducted in Labuange Bay, South Sulawesi for 30 days using cages of 2 x 2 x 2 m3, which were made of 3/4 inch mesh size polyethylene net. The objective of the experiment was to find out the effect of stocking density on growth and survival rate of bigfin squid cultured in floating net cages. The tested stocking densities were 10, 20, and 30 ind/cage. Each treatment was duplicated. The bigfin squid were fed trash fish at satiation. Completely randomized designed was applied. There were no significant differences (P0.05) on survival rate and growth among treatments. The percentages of capsule containing 1, 2, 3, 4, 5, 6, and 7 nucleus were 1.60; 8.20; 30.95; 39.60; 16.20; 3.40; and 0.05 percent respectively and they were not affected by treatments

未知. Penelitian dilakukan selama satu bulan di Teluk Labuange Kabupaten Barru, Sulawesi Selatan, menggunakan keramba ukuran 2 x 2 x 2 m3 yang terbuat dari jaring polietilen ukuran mata 3/4 inci. Penelitian ini bertujuan untuk mengetahui pengaruh kepadatan terhadap pertumbuhan dan tingkat sintasan induk sotong buluh dalam keramba jaring apung di laut. Perlakuan kepadatan induk sotong buluh yang dicobakan adalah 10, 20, dan 30 ekor/keramba. Semua induk diuji diberi pakan rucah secara satiasi. Masing-masing perlakuan terdiri atas dua ulangan dan dirancang dalam rancangan acak lengkap (RAL). Hasil analisis statistik menunjukkan bahwa perlakuan yang dicobakan tidak memperlihatkan perbedaan yang nyata (P0.05) baik terhadap pertumbuhan, maupun sintasan. Persentase jumlah polong yang mengandung 1, 2, 3, 4, 5, 6, dan 7 inti berturut-turut 1,60; 8,20; 30,95; 39,60; 16,20; 3,40; dan 0,05 persen, dan tidak dipengaruhi oleh perlakuan
