- Values are mean of triplicate groups and presented as mean ± SE. Values with different superscript letters in the same row are significantly different (p < 0.05). The lack of superscript letter indicates no significant differences among treatments
- 1Weight gain (%) = [(final body weight − initial body weight)/initial body weight] × 100
- 2Specific growth rate (%/day) = [(ln final body weight − ln initial body weight)/days] × 100
- 3Daily feed intake (%) = (feed intake × 100)/[(initial body weight + final body weight + dead fish weight) × days/2]
- 4Protein efficiency ratio = wet weight gain/total protein given
- 5Feed conversion ratio = feed intake/wet weight gain
- 6Condition factor (%) = (weight of fish/(length of fish)3) × 100
- 7Hepatosomatic index (%) = (weight of liver/weight of fish) × 100
- 8Viscerosomatic index (%) = (weight of viscera/weight of fish) × 100
