Method for artificial indoor breeding of crawfishes

Abstract

The invention relates to the field of breeding crawfishes, in particular to a method for artificial indoor breeding of crawfishes. The method specifically includes the following steps of 1, selectinga site; 2, preparing a crawfish survival box rack; 3, conducting sterilization and placing soil; 4, placing grass and stone; 5, putting young crawfishes; 6, adjusting the pH value; 7, putting feed; 8,adjusting the temperature; 9, conducting sterilization and disinfection; 10, conducting fishing. By adopting a workshop-type crawfish breeding mode, compared with a traditional method of building a breeding pond for breeding, the method has the advantages that refined breeding is achieved, correspondingly the growth speed of the crawfishes is high, invasion of other external creatures is avoided,and therefore the crawfishes are safe and free of parasitism of harmful bacteria; meanwhile, the feed is abundant in nutrient, water is clean and fresh, the edible quality of the crawfishes can be improved, and the market share and profits of the crawfishes are increased.

[0002] The fishing time of crayfish is often determined by the amount of rain in early spring. The time when the parent shrimps emerge from the hole in the previous year is determined. Therefore, the early consumption market mainly supplies egg-bearing shrimps from the previous year. In order to purchase early, crayfish buyers generally enter the first-line breeding directly. region to ensure a stable supply of crayfish. With the improvement of living standards, the supply of early crayfish is in short supply. As first-line crayfish farmers, in order to stagger the mid-term shrimp production peak and seize the price advantage, some Farmers often purchase early high-priced shrimp seedlings in advance to start farming. In addition, farmers in some areas such as Jianli County try out-of-season crayfish farming. However, traditional farming is carried out in breeding ponds, which are greatly affected by the external climate. Rainwater delays the time for broodstock to emerge from the hole and affects the sale of farmers, while indoor farming has no such problems. The indoor profit margin of the early market is larger than that of breeding ponds
