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

Embodiment Construction
[0022] A kind of cultivation method of crayfish of the present invention, its step is as follows:
[0023] 1) Site construction: including aquatic plant reserve pond, ecological pond and adult shrimp pond;
[0024] Spare pool for aquatic plants: occupying 2-5% of the site area, common earthen pools or paddy fields are acceptable, and the water depth is 0.8-1 meter;
[0025] Ecological pool: earthen pool, occupying 70-75% of the site area, the height of the ridge is 1.2-1.5 meters, the width of the bottom is 2.5-3.5 meters, and the width of the ridge is 1.5 meters. Zizania can be planted to cover 1 / 3 to 1 / 2 of the area of the ecological pool; water peanuts and / or cowgrass can be planted on the edge of the pool, the rhizomes and leaves of Zizania survive longer than ordinary aquatic plants, and can survive the winter; in summer, the leaves can Cool the crayfish, and protect the crayfish from the cold in winter;
[0026] Shrimp Pond: Occupies 20-25% of the site area, with an ...

The invention discloses a culture method of crayfish. The culture method of the crayfish comprises the following steps: 1) carrying out site construction, comprising an aquatic plant standby pool, an ecological pool and an adult shrimp pool; 2) cultivating young shrimps; 3) rearing the young shrimps; 4) separating the young shrimps; 5) breeding adult shrimps; and 6) carrying out crayfish management, comprising: 1, disease prevention and water diversion; and 2, oxygenation. The culture method of the crayfish has the advantages that the aquatic plant standby pool, the ecological pool, the adult shrimp pool, a temporary culture pool and a shelling and dust removing pool are arranged, the crayfishes are intensively concentrated and cultivated, and the problems that yield is low, the crayfishes can escape easily, quality is poor and no crayfish is sold in winter are solved; and acre yield of the crayfish is improved, so that the acre yield of the adult shrimp pool is about 600kg.
Description
technical field [0001] The invention belongs to the technical field of cultivation of fish, mussels, clams, lobsters, sponges, pearls, etc., and in particular relates to a method for cultivating crayfish.
