FIELD: agriculture.
SUBSTANCE: method includes capturing of fertilised females in natural reservoirs or stock ponds upon achievement of water temperature of 13-15°C. The females are transported, sorted and contained in the incubatory pools with closed water supply cycle, in which the cassettes with individual shelters are preliminary fitted. The heating system is used, increasing the temperature of water in the pools by 1.0°C per day and when it is brought up to 25°C it is maintained at this level until hatching. The light day is regulated (14 hour day and 10 hour night). The process of feeding is carried out adequately to the stages of larvae embryogenesis.
EFFECT: increased efficiency of the method.
