Embodiment Construction

[0020] Build 2000m 2 In the breeding ground, the water depth is 1m, the pond has a slope, the bottom of the pond is flat, and the bottom is sandy soil. In the center of the pond, there is a mud ridge that is 4 / 5 long by the side of the pond, 1 meter wide, and 5-10cm above the water surface. Connected; smooth anti-escape nets are installed around the pond, which is convenient for irrigation and drainage. The water sources used are all in line with fishery water standards, and aquatic plants are planted at the bottom of the pond. Disinfect the breeding ground and fertilize. In early April when the weather is fine, put 4% light salt water sterilized shrimp seedlings at noon. Special feed for lobster, protein ≥ 25%, put in once a day, the amount of feeding is 2% of the total weight of the shrimp body; It is 1.5% of the total weight of the shrimp body, and it is adjusted according to the actual situation. Fishing starts in July with ground cages. After 5 days of continuous opera...

Abstract

The invention relates to a pollution-free Africa crayfish artificial breeding method. The method includes the following steps that a local pond is used for arrangement and sterilization, water quality is adjusted with poultry manure after fresh water is injected, and waterweeds are cultured at the water bottom; 15 days later, juvenile crayfishes are put into the pond on sunny days in the early April; three months later, the crayfishes can be fished and sold on the market. The mode that large crayfishes are fished, small crayfishes are left and alternating fishing is achieved is used during fishing, and the yield of the crayfishes can be ensured. By means of the method, the yield and benefits of the crayfishes can be effectively improved, and the development of the crayfish aquaculture industry is promoted.

Description

technical field [0001] The invention relates to a pollution-free artificial breeding method for African crayfish, in particular to large-scale pollution-free breeding of crayfish, which can make full use of local pond resources, improve the quality and output of crayfish, and increase economic benefits. Background technique [0002] Crayfish breeds fast, has a short breeding cycle, and at the same time has delicious meat, rich nutrition, large market demand, broad development prospects, high economic benefits, and widely exists in freshwater ponds in my country. However, due to serious water pollution, the quality of wild crayfish has been seriously affected; at the same time, overfishing of wild resources and backward artificial breeding techniques have caused the degradation of germplasm resources and the decline in production. How to improve the germplasm resources, ensure its quality and yield, and improve economic benefits by improving the artificial breeding technology...
