Crayfish breeding method

Abstract

The invention discloses a crayfish breeding method. The crayfish breeding method comprises the following specific steps of 1, selection of a culture pond, wherein the depth of the pond is 0.8-1 meter,an escape-proof facility which is 50 centimeter high is arranged around the pond, the depth of water in the culture pond is 12-15 centimeter, and filter screens are arranged at a water inlet and a water outlet of the culture pond respectively; 2, disinfection of the culture pond, wherein before water injection for breeding, the pond is desilted, washed and exposed to the sun, the culture pond isdisinfected with calcium oxide every five days, aquatic plants grow on the circumference in the culture pond, and the aquatic plant covering area accounts for one third of the water surface of the culture pond; 3, control over the quality of the water, wherein the pH of the water in the culture pond is maintained to be within the range from 6.5 to 7.5, the temperature of the water in the culture pond is maintained to be 18-24 DEG C, and the transparency of the water is controlled to be 30-40 centimeters or above; 4, seed preparation before breeding, wherein 3500-4500 crayfishes are put in eachmu of culture pond, the weight of 150 crayfishes is about 500 g, 5-15 chubs are put in each mu of culture pond, and the young crayfish seeds which carry no pathogenic bacteria and have normal body color and complete appendages are selected to be put into the water.

Description

technical field [0001] The invention relates to the field of aquatic product culture design, in particular to a method for cultivating crayfish. Background technique [0002] Crayfish is fresh and tender, delicious and nutritious. It is a high-protein and low-fat aquatic food, so it is widely liked by people. At the same time, with the improvement of living standards, people's pursuit of delicious food is becoming more and more intense. The demand for lobsters is increasing, so the artificial culture of crayfish has become an imperative trend, but in the prior art, the methods for cultivating crayfish are limited, resulting in slower growth and poor quality of crayfish . [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] For the problem in the related art, the present invention proposes a kind of culture method of crayfish, to overcome the above-mentioned technical problem that exis...
