Abstract

The article presents the fish-breeding, biological and physiological justification while using the prebiotic "Ceobalyk" as part of production compound feeds for clary catfish grown in a hot spring. Experimental studies were conducted on the basis of the fisheries of "TENGRYFISH" LLP. A balanced compound feed was fed to the control group of fish, and in addition to the main diet, the prebiotic "Ceobalyk" in the amount of 5% and 10% was administered to the two experimental groups.The duration of the study was 61 days. It was proved that the introduction of prebiotic into the main feed had a positive effect on the growth rates of catfish and their physiological state. The absolute increase in the fish of the experimental groups during the growing period with the addition of a prebiotic in relation to the control was higher by 4.9% and 13.6%, respectively.The survival rate in the second variant was 96%. As a result of the research, the optimal dose of the prebiotic "Ceobalyk" in the amount of 5% in the composition of production compound feeds for clary catfish was established. The results obtained indicate the expediency of using the prebiotic "Ceobalyk" in fish farming and the prospect of further studying its effect on the physiological and biochemical parameters of the organism of clary catfish.
