^aIntial body weight (IBW, g) = initial total body weight/initial number of fish; ^bFinal body weight (FBW, g) = final total body weight/final number of fish; ^cSurvival rate (SR, %) = 100 × final number of fish/initial number of fish; ^dFeed intake (FI, g fish⁻¹) = 100 × total feed intake/final number of fish; ^eWeight gain rate (WG, %) = 100 × (final body weight–initial body weight)/initial body weight; ^fSpecific growth rate (SGR, % day⁻¹) = 100 × (ln (final body weight)–ln (initial body weight))/feeding days; ^gFeed conversion ratio (FCR) = weight of feed consumed/weight gain; ^hProtein efficiency rate (PER) = 100 × (final total body weight–initial total body weight)/(total feed intake × protein proportion in feed); ⁱCondition factor (CF, g cm⁻³) = 100 × body weight/body length³; ^jViscerosomatic index (VSI, %) = 100 × viscera weight/whole body weight; ^kHepatosomatic index (HSI, %) = 100 × liver weight/whole body weight. Values are means ± SEM of three replications. Means in the same row with different superscripts are significantly different (P < 0.05).
