Bioflavonoids, also known as flavonoids, are substances with low molecular weight that are found in vascular plants. They are found in all parts of plants, but especially in photosynthetic cells and have a wide spectrum of action as antioxidants, enzymatic inhibitors, precursors of toxic substances, protection against ultraviolet radiation, and also participate in energy conversion. The article discusses the experience of using a new generation antioxidant – dihydroquercetin and an immunostimulator – arabinogalactan in feeding sturgeon fish. The objects of research in the work were: two-year-olds of Russian sturgeon, as well as dihydroquercetin, arabinogalactan and feed formulations for sturgeon fish species. In the process of work, the formulation of a full-fledged compound feed for sturgeon fish species was adjusted using the bioflavonoid dihydroquercin, an arabinogalactant immunostimulator, and the productive effect of feed on fish was evaluated according to fish-biological and physiological indicators. The obtained results complement the existing ideas about the fields of application of antioxidants, and also prove the prospects of using herbal remedies as antioxidant feed additives. The results obtained in the course of research can serve as a basis for improving technologies for the production of compound feeds when growing fish on an intensive basis.
