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