Currently, the general trend of the global fishing industry is to increase the production of fish food products not only due to the development of aquaculture, but also the biological characteristics of the body of sturgeon. The aim of the study was the theoretical justification and practical implementation of the assessment of the growth and development of beluga juveniles and their hybrids with sterlet aged 0+ to 2+ (three-year-olds) in industrial of the Krasnodar Territory. The determined: fish mass, live weight gain, linear growth. By the end of the control cultivation, the weight of fish in the control and experimental groups was 1728.3 and 2236.4 g, respectively. In the experimental group, the absolute increase in live weight of fish was 2198.2 g, while in the control group it was 1692.2 g. The difference in average daily gains was 0.71 g in favour of hybrids. The body length of the fish in the control and experimental groups was 32.7 and 37.3 cm. The positive effect of heterosis had a positive effect on the first- generation crossbreeds obtained from beluga and sterlet.
