Analysis of Growth Parameters
After 35 days, all fish were measured individually for weight and length. Growth parameters such as specific growth rate (SGR) and weight gain (WG) were calculated as follows (Pechsiri and Yakupitiyage, 2005):
SGR (%body weight gain/day) = [(ln final weight–ln initial weight) / time (days)] × 100
WG (g) = mean final weight (g) – mean initial weight (g)
The total weight of liver was taken to measure the hepatosomatic index (HSI) according to the following formula (Sadekarpawar and Parikh, 2013):
HSI = [Liver weight (g) / Fish weight (g)] X 100
