Abstract

The invention discloses a method for breeding crayfish. The method comprises the following steps: 1) selection of a culture pond; 2) disinfection treatment; 3) water culture; 4) transplantation of aquatic plants; 5) release of shrimp seeds: In 1-3 d before the shrimp seeds are released, first pistia stratiotes is released at the rate of 20-30 kg / mu, and snails should be released at the rate of 50-100 kg / mu; then the shrimp seeds are released at the density of 100000 to 120000 / mu; 6) feed feeding: the crayfish feed is used as feed for feeding; the daily feed feeding amount was 10-20% the totalquantity of crayfish, and the feed is fed three times in the morning, noon and late nights; in the feeding process, a Chinese herb decoction is administered once a month, the dosage is 10-20 kg / mu, and the Chinese herb decoction is obtained by adding water and decocting radix astragali, radix codcnopsitis pilosulas, rhizoma Atractylodis, polyporus umbellatus and radix glycyrrhizae by specific ratio. The method can effectively improve the survival rate of crayfish.

Description

technical field [0001] The invention relates to an aquaculture method, 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 media promotion, freshwater crayfish food has generally entered restaurants, hotels, supermarkets and family dining tables. [0003] At present, crayfish farming is developing rapidly in my country, but during the growth process of crayfish, crayfish are susceptible to diseases, resulting in the inability to effectively increase the production of crayfish and reduce economic benefits. Contents of the invention [0004] The technical problem to be solved...
