Abstract

The invention relates to the technical field of breeding of fishes, mussels, clams, lobsters, sponge, pearls and the like, in particular to a crayfish breeding method. The method includes the steps ofS1, site construction, S2, separation of young crayfishes and S3, storage of the young crayfishes. The site construction includes constructing constant-temperature environment-friendly warm sheds, avisible water breeding pond and a three-dimensional yield-increasing brooding pond. The storage of the young crayfishes includes that one cold shed for storing the young crayfishes with the standard size of 1cm is provided for every two constant-temperature environment-friendly warm sheds. The crayfish breeding method has the advantages that the survival rate of the young crayfishes can be remarkably increased to approximately 50% through reasonable layout of the ponds and the separate breeding in the three-dimensional pond, and the yield can be increased from 100,000 per mu to 150,000 per mu;the water area is increased, the breeding density is reduced, and the yield per mu of the young crayfishes can be increased; the method is applicable to cold regions in winter.

Description

technical field [0001] The invention relates to the technical field of cultivating fish, mussels, squids, lobsters, sponges, pearls, etc., and specifically relates to a method for cultivating crayfish seedlings. Background technique [0002] In 2018, the total output of crayfish in the country was 1.77 million tons. Although some farmers in Liaoning area tried to raise them, they were all small-scale trial breeding, and the output was almost negligible to zero. Therefore, the prospect of breeding promotion in Liaoning area is broad. Crayfish sales are booming in the catering service industry. There are various chain lobster shops in Liaoning. However, the crayfish purchased are long-distance purchases in the south, and the transportation costs are expensive. Local farming can save high transportation costs, and the price in the northern market is more advantageous. The crayfish production in the south is concentrated from March to July. Once the water temperature is higher t...
