The article presents the results of research on the physiological and biochemical state of sturgeon juveniles using various functional loads at the early stages of post-embryonic development of sturgeon raised on an experimental diet in the presence of live food. The article analyzes the effectiveness of the application of functional load methods and feeding regimen to establish the physiological status of released juveniles to replenish natural populations. The article provides information about the stability of young sturgeon fish during the period of release from sturgeon hatcheries to replenish the natural population, further entry from fresh to sea water, and placement in places of natural feeding. The temperature and salinity of water for hydrobionts is a factor that has an integral effect on the activity of functionally important systems of the body at all stages of the life cycle. Juveniles obtained from artificial generations and grown in a combined way on various feeds retain high plasticity, adequate nutrition forms an osmoregulatory function and resistance to temperature conditions of the environment. It is proved experimentally that the feeding regime is an important factor affecting the fish-breeding and biological and physiological and biochemical parameters of young Russian sturgeon, stellate sturgeon and bester.
