Embodiment Construction
[0016] The present invention will be further described below in conjunction with embodiment.
[0017] The crayfish culture method of the present embodiment comprises:
[0018] 1) Pond preparation: set up drainage equipment for the pond, arrange anti-escape facilities around the pond with a height of 50 cm, desilt and expose the pond to the sun before filling the pond, and disinfect the pond with quicklime. Wild predators such as catfish, frogs, snakeheads, snakes, and rats; set a filter at the water injection port. Aquatic plants are planted around, and the coverage of aquatic plants is one-third of the water surface of the pond. The aquatic plants can use the shade of crayfish and the growth of aquatic organisms;
[0019] 2), stocking of seedlings: 25-30 kg of crayfish seedlings are stocked in ponds per mu, and 6-8 silver carp and 50-80 bighead carp are stocked in ponds per mu at the same time. Stocking silver carp and bighead carp can not only be used effectively Pond wate...

Abstract
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.
Description
technical field [0001] The invention relates to a cultivation method, in particular to a crayfish cultivation method. Background technique [0002] In the prior art, due to the lack of scientific breeding methods for crayfish, crayfish are vulnerable to diseases, natural enemies, etc. during the breeding process, with high mortality and low yield. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a crayfish culture method to solve the problems of high mortality and low yield in the existing crayfish culture method. [0004] The crayfish cultivation method of the present invention comprises: [0005] 1) Pond preparation: set up drainage equipment for the pond, arrange anti-escape facilities with a height of 50 cm around the pond, desilt and expose the pond to the sun before filling the pond, and disinfect the pond with quicklime, and set a filter at the water injection port The natural enemies enter the pond with the wa...
