Aquaculture is the fastest growing food production industry. The priority direction of freshwater aquaculture is sturgeon breeding. One of the significant stages of the technological cycle of industrial rearing of sturgeons is the maintenance of juveniles during the transition to exogenous nutrition. In industrial fish farming, based on keeping fish under fully controlled aquatic conditions, the use of natural feed is becoming increasingly limited.Despite the use of artificial compound feed, balanced in terms of the main nutrients, only live food serves as a supplier of all biologically active substances, contains proteins that include all essential amino acids, unsaturated fatty acids, vitamins, enzymes and other vital substances, and also helps to increase the activity of all digestive enzymes, causing the overall activity of the body. The article describes the experience of growing beluga (Huso huso L.) in the pools installed in the RAS “Educational and Scientific Complex of Pilot Aquaculture Production” LLP (Uralsk, Kazakhstan).The results of an experiment to determine the optimal feeding schemes for the sturgeon in the early stages of ontogenesis are presented. It has been established that feeding only аrtemia nauplii and decapsulated аrtemia cysts leads to a mass departure of larvae, and analysis of their stomach contents showed that there was no food in them. To facilitate the transition from feeding live food to artificial food, it is optimal to combine different types of live food with pelleted food. The addition of brine shrimp and bloodworms to the diet of dry granulated food contributes to the greatest increase in the growth rate and survival of larvae and juvenile beluga.
