Crayfish breeding method

Abstract

The invention provides a crayfish breeding method. The method comprises the following steps of S1, site construction; S2, disinfection and fertilization; S2, crayfish specie breeding; S3, seedling raising; S4, rearing; S5, seedling dividing; S6, disease prevention and water transfer; an ecological pond and a grown crayfish pond are set up, and crayfishes are intensively concentration-cultured to solve the problems of low yield, easy escape, poor quality, no crayfish sale in winter and the like; the yield per mu of the crayfishes is improved, the method uses scientific breeding to improve the resilience and the yield per mu of the crayfishes, and improves the survival rate of the crayfishes, a feed is nutritious, which stimulates the growth and development of the crayfishes, the crayfishesare better in quality, and compared with a traditional culture method, the method enables the cultured crayfishes to have larger bodies, higher yield, firmer flesh and more delicious meat.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a method for cultivating crayfish. Background technique [0002] Freshwater crayfish is delicious and nutritious. It is a high-protein, low-fat and high-energy, nutritious health food. It is a worldwide edible shrimp and has become an important food source for European people in the 18th century. The history of eating freshwater crayfish in my country began in the 1960s. With consumers' awareness of freshwater crayfish and the extensive promotion of the media, freshwater crayfish food has generally entered restaurants, hotels, supermarkets and family dining tables.

The history of eating freshwater crayfish in my country began in the 1960s. With consumers' awareness of freshwater crayfish and the extensive promotion of the media, freshwater crayfish food has generally entered restaurants, hotels, supermarkets and family dining tables. Crayfish The demand is very strong, due to overfishing, wild resources are seriously lacking, and the quality of commercial shrimp is uneven; as far as the southwestern region is concerned, the supply of crayfish is insufficient, and there are basically no finished shrimps in winter; most of the crayfish farming methods are trench digging and extensive farming , paddy field co-cultivation, etc., the yield per mu is generally not high
