Values expressed as means ± SE (n = 3). Different superscript letters indicate significant differences for each pairwise comparison between treatments. Weight gain (WG) = (FBW–IBW) × 100/IBW, specific growth rate (SGR) (BW/day) = 100 ((LnFBW–LnIBW)/T), feed efficiency ratio (FER) = WG/FI, feed conversion ratio (FCR) = FI/WG, survival = (final number of fish/initial number) × 100, condition factor (CF) = weigh of fish (g)/(length of fish)3 (cm)3 × 100, FBW, final body weight; IBW, initial body weight; T, trial duration in days; WG, weight gain; and FI, feed intake.
