  1. Data are mean ± standard deviation of three group of fish (n = 45). Values with different superscripts are significantly different (P < 0.05).
  2. ns not significant.
  3. 1 Initial mean body weight.
  4. 2 Final mean body weight.
  5. 3 Survival rate.
  6. 4 Weight gain: (final body weight - initial body weight/initial body weight) × 100.
  7. 5 Specific Growth rate (%): (final body weight - initial body weight)/the time interval in days × 100.
