The increase in the production of aquaculture products confirms the relevance of the development of feed production in order to provide the industry with high-quality compound feeds and feed additives that meet modern requirements and biological needs of cultivated fish. Therefore, the development of aquaculture requires special attention to the feeding process and the use of full-fledged and environmentally safe feeds for all types of aquacultures. Antioxidants of natural origin are increasingly used in feed production. In the course of the work, the positive properties of antioxidant complexes containing the bioflavonoid dihydroquercetin in combination with vitamin E were studied when enriching the diet of a tilapia hybrid (Oreochromis mossambicus × Oreochromis niloticus). As a result of the research, it was found that the inclusion of dihydroquercetin in the composition of production feeds significantly improved productivity indicators and the main criteria for the formation of muscle mass in fish. The use of bioflavonoid dihydroquercetin allowed to increase productivity by 30.0%. The positive effect of the feed additive on morphological and biochemical parameters of blood was noted, which indicates an increase in natural resistance. The study of feed quality indicators confirmed the inhibition of oxidation processes in feed with the addition of dihydroquercetin. During the period of storage of feed in the experimental batch of feed, the level of peroxide number decreased by 3 times, and the acid number decreased by 28.4%. Taking into account the positive properties of bioflavonoid, it is recommended to further study the effectiveness of this biologically active additive in order to introduce it more widely into the practice of feed production.
