The effects of different daily feeding rates on the specific growth rate and food conversion ratio of Siberian sturgeon (Acipenser baeri) were investigated in order to determine the optimum daily feeding rate for fish with an initial mean weight of 1736 ± 37 g. To this end, a Latin Square experimental set-up was designed consisting of four groups of 25 fish fed a rainbow trout diet at four different daily feeding rates (0.75, 1.00, 1.25 and 1.50% body weight/day) for four 2-week periods. Water temperature varied between 19 and 22 °C throughout the experiment. Mean specific growth rate and food conversion ratio values were found to be significantly different (P < 0.05) between the four treatments. The means of specific growth rate and food conversion ratio for fish fed at 0.75%, 1.00%, 1.25% and 1.50% body weight/day were computed as 0.47, 0.88, 0.89 and 0.64% day-1 and 1.71, 1.25, 1.40 and 2.43, respectively. At 19-22 °C the optimum daily feeding rate for Siberian sturgeon of 1736 g was determined to be 1.00% body weight/day.
Abstract

Mean specific growth rate and food conversion ratio values were found to be significantly different (P < 0.05) between the four treatments. The means of specific growth rate and food conversion ratio for fish fed at 0.75%, 1.00%, 1.25% and 1.50% body weight/day were computed as 0.47, 0.88, 0.89 and 0.64% day-1 and 1.71, 1.25, 1.40 and 2.43, respectively.
