Problems solved by technology

[0004] 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

Abstract

The invention provides an anti-season breeding method of crawfish, comprising the following steps: (1) pond selection and construction, namely selecting a pond with sufficient water source and no sludge, wherein the pond comprises shallow water in the center and deep water in the periphery, and the shallow water and the deep water are in bevel transition; a water inlet / outlet is formed in the deepwater of the pond, a filter screen of 30-50 meshes is arranged at the water inlet / outlet, temperature sensors are arranged on the inner side wall and the shallow water of the pond; a greenhouse is erected above the pond, the greenhouse is packaged by a film, a cover layer is added on the outer layer of the film, and a warming apparatus is arranged in the greenhouse; (2) pond disinfection treatment; and (3) feeding, namely putting young crawfish with length of 0.8-1cm into the breeding pond prepared in step (2) and feeding with feed. The breeding method disclosed by the invention can cause breeding of the crawfish in winter or cold regions to be possible, and can reduce the morbidity and increase the yield.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for out-of-season cultivation of crayfish. Background technique [0002] Freshwater lobster, commonly known as crayfish, belongs to the lobster family of the order Crustacea Decapod Arthropoda. It has a thick head and chest, a hard shell, and delicious meat. It is a nutritional and nourishing food with low fat, low cholesterol and high protein. Freshwater lobster not only has a large body and plump meat, but also has the characteristics of short growth cycle, high yield, and strong adaptability to miscellaneous food, which is especially suitable for artificial commercial farming. [0003] At present, my country has a mature technology of growing shrimp in greenhouses. By artificially controlling natural conditions such as temperature, the winter farming of Penaeus vannamei and Macrobrachium rosenbergii has been realized, which not only improves economic benefits, b...
