FIELD: fishing and fish farming.
SUBSTANCE: method involves production of posterity from producers, incubation of caviar, growing of larvas and fry. In adult fry - from young-of-the-year to one-year old fish - an index of content of chlorides or sodium in blood plasma is preliminary determined. Fish growing medium is smoothly salinated with culinary salt with a concentration gradient of 0.5-0.9 ‰ a day to the value of this value, but not exceeding 5 ‰. Fry is grown in this medium to the required body weight, after which the growing medium is desalinated with a concentration gradient of 1-2 ‰ per hour and contains young fish in fresh water for at least 5-7 days.
EFFECT: method provides higher survival rate and growth rate of juvenile fish.
