- 1Values are means of triplicate groups of fish
- 2Weight gain (WG, %) = (final wt. − initial wt.) × 100/initial wt
- 3Specific growth rate (SGR, %) = (loge final wt. − loge initial wt.) × 100/days
- 4Condition factor (CF, %) = (wet weight/total length3) × 100
- 5Feed efficiency (FE, %) = (wet weight gain/dry feed intake) × 100
- 6Protein efficiency ratio (PER) = (wet weight gain/protein intake)
- 7Visceralsomatic index (VSI, %) = viscera wt. × 100/body wt.
- 8Hepatosomatic index (HSI, %) = liver wt. × 100/body wt.
- 9Survival (SUR, %) = 100 × (final fish number/initial fish number)
