Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a method for breeding crawfishes. The method comprises the following steps of S01, separately feeding male crawfishes and female crawfishes until sexual maturity; S02, conducting mixed feeding on sexually mature male crawfishes and sexually mature female crawfishes until the insemination of the female crawfishes is completed; S03, separately feeding the inseminated female crawfishes until young crawfishes are incubated; S04, fishing out the female crawfishes, separately feeding the incubated young crawfishes, regularly sorting the young crawfishes according to the sizes, and feeding the young crawfishes until the mature period. The young crawfishes are regularly sorted according to the sizes, the youngcrawfishes are fed until the mature period, and feed, water temperature and water quality are adjusted according to the sizes of the young crawfishes to ensure the high survival rate and growth rateof the crawfishes. In this way, on one hand, the survival rate of the crawfishes can be improved; on the other hand, the crawfishes in the same size can be fished out simultaneously, so that the crawfishes produced in the same batch are pretty much the same in quality.

Description

technical field [0001] The invention belongs to the technical field of aquatic product cultivation, and in particular relates 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. Crayfish The demand is very strong. Due to overfishing and severe shortage of wild resources, the quality of commercial crayfish is uneven. Therefore, how to solve the uneven quality of crayfish sold in batches is a technical problem that needs to be solved urgently in the industry. Con...
