At the beginning of the trial, four sub-samples of 3 fish each were randomly collected from the remaining acclimated fish for the determination of initial body composition. At the conclusion of the 12-week period, the fish were feed deprived for 1 day prior to sampling, then counted and batch weighed to determine survival, final body weight (FBW), feeding rate (FR), specific growth rate (SGR), feed efficiency ratio (FER) and the condition factor (CF). Eight fish from each tank were randomly collected, killed for the determination of the hepatosomatic index (HSI), viscerasomatic index (VSI), and carcass (without viscera) composition analysis
