Abstract The appearance of new preparations with antioxidant properties allows us to improve the technology of fish feeding and increase the pro-oxidant-antioxidant balance. Due to the fact that an important criterion for choosing a feed additive is environmental safety, natural bioantiooxidants of flavonoid nature, in particular dihydroquercetin, isolated from larch wood, are of interest. It is known that dihydroquercetin has capillaroprotective, lymphokinetic and other properties, but it has a low solubility in water (about 1 g/l), which probably limits its pharmacological activity. In a recent study, it was found that the use of dihydroquercetin (DHA) in a composition with plant polysaccharides increases its pharmacological effect, which is associated with an increase in solubility. One of these commonly used polysaccharides is arabinogalactan, also isolated from larch. The scientific and practical significance of the work consists in testing the effectiveness of bioflavonoids in the composition of production feeds for sturgeon fish as sources of antioxidants, immunostimulants and prebiotics.
