Preliminary results on growth and feeding of wild-caught young goldblotch grouper, Epinephelus costae, in captivity

Growth, food intake, feed conversion, survival and behaviour of wild-caught goldblotch grouper, Epinephelus costae, (initial weight=103.04 ą ; 8.27g) were evaluated when reared in captivity. Average weight gains ranged between 0.106 and 0.278 g day-1, while corresponding gains in length ranged between 0.005 and 0.018 cm day-1. Average daily growth rate was between 0.075 and 0.232% body weight day-1 (overall 0.141 ą ; 0.08 bw/day). Daily rate of feeding was estimated to be between 0.299 and 0.418% bw day-1 (overall 0.365 ą ; 0.09% bw day-1). Food conversion ratio (FCR) ranged between 0.21 and 0.77 (overall FCR=0.423). Food intake was dependent on water temperature.
