Abstract

The influence of salinities and diet on growth performance of tiger grouper (Epinephelus fuscoguttatus) × giant grouper (E. lanceolatus) (TG×GG hybrid), was investigated. TG×GG hybrid (10.0 ± 0.5 cm initial length and 50.5 ± 2.0 gram initial weight) were subjected to different salinities (10, 15, 20, 25 and 30 part per thousand (ppt)) and two diets, commercial pellet (42% protein, 9% ash, 11% lipid, 9% moisture) or trash fish, Sardinella fimbriata (70%protein, 15%ash, 4%lipid, 76% moisture) in triplicates with 15 fish per replication. At the end of the experiment (60 days), the final length, weight, feed consumption (FC), feed conversion ratio (FCR) and specific growth rate (SGR) were calculated. The highest mean SGR (1.05± 0.02% BM day-1, P<0.05) was observed in the 15 ppt + pellet group of fish, while the lowest SGR was observed in the 30 ppt + trash fish group (0.40 ± 0.05% BM day-1, P<0.05). The highest FC was significantly (P<0.05) observed at 15 ppt on both diets. The lowest FCR (1.21± 0.15, P<0.05) was observed in the 15 ppt on pellet diet. The results denotes that 15 ppt fed with commercial pellet is the optimum condition for growth performance of TG×GG hybrid grouper juveniles.
