The effect of feed with probiotics B-1895 and Subtilis-C on the growth and physiological condition of sterlet producers in the RCD was studied. It was found that the weight gain in the first experimental group was higher by 13.3 % and in the second group by 53.3 % in comparison with the control. A positive effect of the probiotics studied on the stabilization of the physiological state of the fish that experienced little stress at the beginning of the experiment has been revealed. As a result, the normalization of physiological and biochemical parameters with a decrease in blood levels of haemoglobin, cholesterol, triglycerides and beta-lipoproteids is noted. No significant effect of the probiotics studied on the generative function was found. Besides a positive effect of the probiotic «Subtilis-C» on the prevention of oocyte resorption was shown.
