FIELD: fish breeding.
SUBSTANCE: invention relates to the field of fish breeding, in particular to the method for adapting pilengas mullet to dry granulated mixed fodder. The method includes catching fish, primary quarantine, joint maintenance of different age groups, feeding fish 2-3 times a day. Adaptation is carried out in conditions of closed water supply with an oxygen content in the water not lower than 6.5 mg/l, water temperature of 19-21°C, and pH of 6.7-8.1 in stages, wherein at the first stage, lasting 5 days, the share of minced fish is gradually reduced to 85% with a simultaneous increase in the share of mixed fodder to 15%, at the second stage, lasting 3 days, the share of minced fish is reduced to 70%, while increasing the amount of granulated mixed fodder to 30%, at the third stage, lasting 7 days, the share of minced fish is 50%, and the share of mixed fodder is 50%, at the fourth stage, lasting 5 days, the share of mixed fodder is 85%, and the share of minced fish is 15%, after which the minced fish is completely withdrawn within three days and the fish are transferred to dry granulated mixed fodder.
EFFECT: use of the invention will increase the survival rate of pilengas producers.
