Abstract

The invention provides a method for breeding crayfishes in winter. The method for breeding the crayfishes in winter comprises the following steps of: (1) selecting and constructing a pond: the pond with a sufficient water source and no silt is selected, the selected pond includes a central shallow water area and a deep water area around the central shallow water area, and a slope is arranged between the two areas for transition; a water inlet and a water outlet are formed in the deep water area of the pond, filter screens of 30-50 meshes are arranged at the water inlet and water outlet, and temperature sensors are arranged on an inner side wall of the pond and the bottom of the shallow water area; a greenhouse is constructed above the pond and covered with thin film, a cover layer is addedonto the thin film, and a thermal insulation device is arranged in the greenhouse; (2) disinfecting the pond; and (3) performing feeding: crayfish seedlings with the length of 0.9-1.1 cm are put intothe cultivation pond prepared in the step (2), and feeding the crayfish seedlings with feed. According to the method for breeding the crayfishes in winter, it is made possible to breed the crayfishesin winter or in cold regions, the incidence is reduced, and the yield is improved.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for cultivating crayfish in winter. 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, but also...
