The invention discloses a method for culturing crayfishes. The method includes the steps of 1, preparing a pond; 2, breeding young crayfishes, wherein 25 kilograms to 30 kilograms of young crayfishes are bred in per mu of the pond; 3, throwing feed, wherein animal feed is mainly thrown in April and May, vegetable feed is mainly thrown in June, July and August, and animal feed is mainly thrown in the period from the late September to the catching period; 4, controlling the water quality, wherein 15 cm to 20 cm of water is added per week; 5, preventing and treating diseases, wherein pond water is sterilized through quick lime at regular intervals, and the use amount for one-meter-depth water is 15 kilograms per mu; 6, carrying out catching at the right moment, wherein after the crayfishes lay eggs, when young crayfishes grow to have the weight ranging from 40 g to 50 g, the adult crayfishes are caught. According to the method for culturing the crayfishes, as the links such as the pond, the young crayfish breeding number, the feeding amount, the feeding time, the water quality, disease preventing and treatment and catching are reasonably controlled, injuries of natural enemies, diseases and the like to the crayfishes can be greatly reduced, the survival rate of the crayfishes is high, the growth speed is high, and the yield is high.
