Cement pit breeding method of langoustine

Abstract

The invention discloses a cement pit breeding method of langoustine, comprising the steps of seed selection, mating, hatching, juvenile langoustine breeding and langoustine seed catching. According to the invention, the seed selection standard of the parent langoustine is strict, and the old, weak, sick and disable parent langoustine are sifted out, thereby laying foundation for breeding health juvenile langoustine with high quality; since the parent langoustine used for breeding is different in resource, inbreeding is avoided, and the quality of the juvenile langoustine is ensured; oogenesis parent langoustine refers to oogenesis parent langoustine laying egg in the same period, the yield is high and the langoustine seeds are kept consistent in size; the disease resistance of the langoustine seed is strong, the loss of langoustine workers is reduced, and the cultivation benefit is increased; furthermore, according to the invention, parent langoustine transfer is simple and convenient, the langoustine seed catching is simple and feasible, and the labor intensity is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of shrimp breeding, in particular to a crayfish breeding method in a cement pond. Background technique [0002] Crayfish, native to North America (that is, the southern United States and northern Mexico), belong to the phylum Arthropoda, and were introduced to my country from Japan in the late 1930s. Crayfish have the living habit of burrowing, destroying dams, threatening the survival of fry, and causing certain damage to agricultural production and fishery production. Therefore, early people have always eliminated them as harmful organisms. In recent years, crayfish has been sought after because of its delicious meat, and the market prospect is good. However, due to the lack of artificial breeding of crayfish, people catch a large number of wild crayfish, making their natural population less and less. The market is in short supply and the price has risen sharply. Therefore, artificial breeding is imperat...

Problems solved by technology

[0003] In addition, the predecessors have discussed the artificial breeding of crayfish, but it mainly involves reproduction, and does not involve the selection, mating and juvenile shrimp breeding of crayfish broodstock. Therefore, artificial breeding of crayfish tends to make individuals smaller and weaker in disease resistance Therefore, there is an urgent need to re-select healthy and good crayfish seedlings and put them on the market to reduce losses for shrimp farmers and increase breeding benefits
