Budi daya ikan kerapu sunu masih mengandalkan pasokan benih dari alam, padahal keberadaanya tergantung musim. meningkatnya kebutuhan benih untuk budidaya maka perlu dilakukan pembenihan secara buatan untuk mengantisipasi kebutuhan benih yang berkesinambungan

Abstract

The aim of this research was to find out the influence of the chronic hormone LHRH-a and 17α-MT on non-specific immune response of mangrove grouper, Epinephelus coioides broodstock. Female and male fish weight used in this experiment ranged 4.7-10.4 kg and 10.4-17.8 kg, respectively. The female fish were treated with hormone 17α-MT at a dosage of 50 µg/kg body weight, while the male fish treated with hormone LHRH-a at dosages of 50 and 100 µg/kg body weight. Fish were kept separately in two concrete tanks contained 100 m³ sea water, and 2 meters depth. The stocking density was 15 fishes/tank with male and female ratio 1 : 2. The blood samples were colected before treatment by hormone and every two months, subsequently. The non-specific immune response parameters evaluated were phagocytic activity (PA), phagocytic index (PI), and lysozyme activity (LA). Results indicated that chronic hormone could increase non-specific immune response especially phagocytic activity up to 17.3%.
