It is shown that increasing the efficiency of the technology of obtaining fish breeding material of aboriginal fish species, in particular freshwater sterlet, for further reintroduction into natural reservoirs is achieved by applying the developed technologies for increasing the biomass of biomass producers of BAS with the subsequent creation of functional feeds and feed additives on their basis. The methods of bioencapsulation of probiotics, carotenogenic yeasts and microalgae as producers of essential nutrients in live feeds have been developed, which provided acceleration of growth rates and reduction of mortality rates of early juvenile fish. The effectiveness of correction of the nutritional value of algocultures and carotenogenic yeast by the preparation of nanosized cerium has been shown. The possibility of reducing the effective concentration of biocidal preparations based on ethylthiosulfonylates by their combined use with biosurfactants has been proved. According to the results of the work, the volume of stocking was calculated and fish stocking material of freshwater sterlet with increased adaptive properties for effective reintroduction into natural hydroecosystems was obtained.
