Note: Data in the table are represented as means ± SD (n = 9). BW, body weight; WGR, weight gain rate; SGR, specific growth rate; SR, survival rate. HSI, hepatopancreas index; HSI (%) = 100 × hepatopancreas wet weight/body wet weight; GSI, gonadosomatic index; GSI (%) = 100 × gonad wet weight/body wet weight; Tukey test of statistical analysis is used to compare the means, values in each row with different superscripts are significantly different ().
