  1. Values are means ± SEM of four replicates, and values within the same row with totally different letters in superscript are significantly different (P < 0.05). IW (g), initial weight; FW (g), final weight; Weight gain (WG, %) = 100 × (final weight – initial weight) / initial weight; Specific growth ratio (SGR, %) = 100 × (ln FW – ln IW) / time (days); FI (g fish− 1), food intake; PR (%) = (fish protein gain) × 100 / (protein intake)
