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

Preliminary results on growth and feeding of wild‐caught young goldblotch grouper, Epinephelus... Summary Growth, food intake, feed conversion, survival, and behaviour of wild‐caught goldblotch grouper, Epinephelus costae Steindachner, (initial weight=103.04 ± 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 ± 0.08% bw/day). Daily rate of feeding was estimated to be between 0.299 and 0.418% bw day−1 (overall 0.365 ± 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Applied Ichthyology Wiley

Abstract

Summary Growth, food intake, feed conversion, survival, and behaviour of wild‐caught goldblotch grouper, Epinephelus costae Steindachner, (initial weight=103.04 ± 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 ± 0.08% bw/day). Daily rate of feeding was estimated to be between 0.299 and 0.418% bw day−1 (overall 0.365 ± 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.
