Abstract :The effects of different daily feeding rates on the specific growth rate and food conversion ratio of Siberian sturgeon insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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.
