  1. Survival rate = (the number of survived fries/the number of hatched fries) × 100. Survival rate was measured at 10 days after hatched
  2. Each value is mean and standard deviation percentage of triplicate experiments (n = 30). Means in columns having different superscript letter are significantly different (P < 0.05)
