METHOD FOR REPRODUCTION AND GROWING OF STURGEON FISH Russian patent published in 2007 - IPC A01K61/00 

FIELD: fishery.

SUBSTANCE: method involves keeping mature fish sires in ponds with optimal hydrochemical, oxygen and temperature modes in habitat; feeding; providing pre-spawning keeping of sires; obtaining spawn and larvae; during prep-spawning keeping period, adding active preparation into pond populated with sires, said active preparation being added in an amount of 0.05-5 ml/l; holding during 1-4 hours under oxygenation conditions; setting water exchange at the rate of 10-30 l/min; before separating reproductive products, treating 3-5 times; providing degumming of impregnated spawn by single adding of the same biologically active preparation at concentration of 0.01-0.1% during 1 hour; treating larva during the first day beginning from pecking out time and before beginning of active feeding period; before time of delivery into nursery ponds, feeding young fishes by adding into feed of biologically active preparation in an amount of 10-20 ml/kg, mineral water being used as biologically active preparation and having general mineralization of 2-4 g/dm³ and content of calcium cations of 30-150 mg/dm³, magnesium cations of 390-450 mg/dm³, sodium cations of 10200-5320 mg/dm³, iron cations 11-57 mg/dm³, selenium cations of <1 mg/dm³, copper cations of 1-3 mg/dm³, anion-sulfates of <50 mg/dm³.

EFFECT: provision for producing of vital progeny, retention of mother herd and increased efficiency in reproduction of valuable fish breed such as sturgeons.
