Values are mean of triplicate groups and presented as mean ± SD. Values in the same column having different letters are significantly different (LSD; P < 0.05)
¹FBW (g) = Final body weight
²Weight gain (%) = [(final body weight - initial body weight)/initial body weight] x 100
³Specific growth rate (%) = 100 x [ln(final body weight) – ln(initial body weight)]/days
⁴Feed conversion ratio = dry feed fed/wet weight gain
⁵Protein efficiency ratio = fish weight gain (g)/protein
⁶Feed intake (g/fish) = dry feed consumed (g)/fish
⁷Survival (%)
