Duncan’s multiple range test was performed in all groups, and values within a row with a common superscript letter are not significantly different from the other dietary groups (; mean ± SEM; n = 3). Survival rate (SR, %) = final fish number/initial fish number × 100. Feed efficiency ratio (FER) = increased body weight/dry feed consumed. Weight gain rate (WGR, %) = (final body weight − initial body weight)/initial body weight × 100. Specific growth rate (SGR, %/d) = Ln (final body weight/initial body weight)/experimental days × 100. Hepatosomatic index (HSI, %) = liver weight/body weight × 100. Viscerosomatic index (VSI, %) = viscera weight/body weight × 100. Condition factor (CF) = final body weight (g)/length (cm)³ × 100.
