FIELD: fishing industry.
SUBSTANCE: method includes fishing out producers of different varieties and stages of maturity. Brood stock reserve in seawater with salinity 3.07÷8.00 ‰ before puberty of producers. From producers of naturally matured in salinity of sea water up to 3.06 ‰ mature gametes are obtained and fertilised eggs are produced. Fertilised eggs are delivered to incubation shop of hatchery where they are incubated in river water until hatching, resorption of yolk sac and transition to active feeding larvae live food outside. At onset of signs of readiness to migrate to feeding grounds juveniles are placed in sea water and grown in salinity range of 2.5÷7.00 ‰ to viable stages.
EFFECT: invention provides reproduction of stellate sturgeon populations and Baltic salmon.
