FIELD: agriculture.
SUBSTANCE: invention relates to the fish-culture sphere and can be used in such spheres as eurythermic fish's breeding and reproduction. The method is realised by changing incubation temperature. Thus while changing the speed of water temperature 1-1.5°C/hour twice a day variable thermo-mode is formed determined from the condition: Tu=To+1.5 Tl=To-1.5 where: Tu and Tl - the upper and lower borders of thermo-mode; To - constant optimal temperature.
EFFECT: invention makes it possible to increase larva survival and improve physiological condition of eurythermic fish in early stage growth.
