METHOD FOR INCREASING VITALITY OF FISH SPAWN, LARVAE AND YOUNG FISHES Russian patent published in 2007 - IPC A01K61/00 

FIELD: fishery, in particular, fish rearing for producing of physiologically full-value young fishes such as salmons.

SUBSTANCE: method involves processing spawn and larvae during period of transfer to exogenous feeding using biologically active preparation, with mineral water being used as biologically active preparation having general mineralization extent of 2-4 g/dm³ and content of calcium cations of 30-150 mg/dm³, magnesium cations of 390-450 mg/dm³, potassium cations of 50-70 mg/dm³, sodium cations of 10200-5320 mg/dm³, iron cations of 11-57 mg/dm³, selenium cations <1 mg/dm³, copper cations of 1-3 mg/dm³, anion-sulfates <50 mg/dm³; processing spawn during impregnation and during the entire incubation period; processing larvae immediately after pecking out and 2-3 times during transfer to exogenous feeding. Mineral water is used in an amount of 0.1-5 ml/l. Young fishes are fed with feed enriched in biologically active preparation used in an amount of 5-50 mg/kg of feed.

EFFECT: increased survival rate at early stages of development of fishes due to increased resistance to stress effects of different character.
