Anti-season culture method for crayfish

Abstract

The invention provides an anti-season culture method for crayfish. The method comprises the following steps: (1) pond construction: selecting a rectangular pond, and building a greenhouse above the pond; (2) aquatic plant growing: one week later after the pond is disinfected, growing alga plants in the pond, and injecting water having a depth of 0.9-1.0m into the pond; (3) young crayfish stocking: disinfecting young crayfish with a 3-5% saline solution, and uniformly putting the young crayfish on the aquatic plants in the pond; (4) crayfish feeding: from late October to March of the next year, regulating the temperature of the pond to 15-20 DEG C, and performing feeding once every day; and from March of the next year to the catching season, regulating the temperature of the pond to 22-26 DEG C, and performing feeding twice every day; and (5) catching: after the crayfish reach catchable sizes, catching the crayfish for sale. According to the anti-season culture method for crayfish, the crayfish can grow in a relatively stable environment, so that the stress is greatly reduced, the incidence rate is effectively lowered, and the yield is increased.

Description

Technical field [0001] The invention relates to the technical field of aquaculture, in particular to a crayfish off-season breeding method. Background technique [0002] At present, our country has mature technology of cultivating shrimp in greenhouses. Through artificial control of temperature and other natural conditions, the winter culture of Penaeus vannamei and Macrobrachium rosenbergii has been realized, which not only improves economic efficiency, but also greatly enriches people's dining tables. The suitable water temperature for crayfish is 9~40℃, and the optimum water temperature for growth is 22~30℃. In freshwater aquaculture, it is better to keep the water temperature above 25°C. [0003] Crayfish made foods are rich in nutrition, delicious and delicious, and are widely welcomed. However, the existing technology for crayfish farming still stays in the southern plains, and for crayfish farming in the north, there is still a winter The problem is that the winter causes ...

Problems solved by technology

[0003] The food made by crayfish has the characteristics of rich nutrition, delicious taste and is widely welcomed. However, in the existing technology, the culture of crayfish still stays in the southern plains. The problem is that winter causes a large number of diseases and deaths of crayfish, and the production of crayfish is difficult to meet market demand
