Values are mean of triplicate groups and presented as mean ± SD.
Values with different superscripts in the same column are significantly different (p < 0.05).
Final body weight (FBW, g/fish).
Weight gain (WG, %) = 100 × [Final body weight (g) – Initial body weight (g)] / Initial body weight(g).
Specific growth rate (SGR, % day–1) = 100 × (ln final body weight − ln initial body weight) / Days.
Feed conversion ratio (FCR) = Dry feed intake (g) / [Final body weight (g) – Initial body weight (g)].
Protein efficiency ratio (PER) = [Final body weight (g) – Initial body weight (g)] / Protein intake (g).
Conditional factor (CF, g/cm3) = 100 × Fish weight (g) / Fish length (cm)3.
Hepatosomatic index (HIS, %) = 100 × Liver weight (g)/ Fish weight (g).
