Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with specific embodiments.

[0017] A kind of crayfish breeding seedling raising method of the present invention comprises:

[0018] (1) Cultivation pond construction: The cultivation pond adopts an earthen pond, the depth of the pond is 0.5-1 meter, the width of the pond ridge is 1.5 meters, and the drainage system is built. The surrounding pond ridges are built with plastic films to prevent escape. The water source of the cultivation pond is sufficient and the water quality is fresh. No pollution; 15 days before broodstock stocking, spray 150-180 kg of quickliming water per mu for disinfection, and at the same time apply 500-800 kg of decomposed livestock and poultry manure to improve water quality, then inject new water, and place bamboo tubes and branches in the pool , and transplant aquatic plants. The area of ​​aquatic plants accounts for 1 / 3 of the area of ​​the cultivation pool. The aquatic p...

Description

technical field [0001] The invention relates to the technical field of shrimp breeding and seedling cultivation, in particular to a crayfish breeding and seedling raising method. Background technique [0002] Crayfish, native to North America, were introduced into my country through Japan. After decades of natural reproduction and artificial breeding, they have become one of the important freshwater economic shrimps in my country. Crayfish are delicious and nutritious. High-protein, low-fat, high-energy food is deeply loved by people. With the increase of people's demand, it has driven the rapid development of my country's crayfish farming industry and directly stimulated the demand for seedlings. The traditional crayfish seed breeding method has low survival rate, low yield and poor benefit, which greatly affects the enthusiasm of farmers. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a crayfish breeding and...
