The article discusses the prospects for using probiotics in aquaculture. The effect of probiotics on the physiological processes in the body of African catfish grown under artificial breeding is discussed. The effectiveness of using probiotics to increase productivity, improve the gastrointestinal tract of fish, increase non-specific resistance and stress resistance is analyzed. The results of our own research on the use of the probiotic Subtilis, which is currently used in many industries, including fish farming, are presented. The aim of the work was to study the effect of the probiotic subtilis on the erythron system and on the structure of the leukocyte formula of African catfish. Against the background of the probiotic subtilis, the total number of red blood cells in the bloodstream was increasing, and the proportion of immature forms was progressively decreasing. The seasonal dynamics and sexual characteristics of the catfish peripheral blood system were studied with the use of a probiotic. In general, the stimulating effect of the probiotic subtilis on erythropoiesis and the white blood system was found. Analysis of the leukogram of African catfish indicated the activation of the cellular component of the immune system when using a probiotic in feeding. Our results allow us to recommend the use of the probiotic subtilis for the cultivation of African catfish in industrial aquaculture. This work was supported by the Russian Foundation for Basic Research with the grant 18-016-00127.
