Example Embodiment

[0023] Example 1, such as figure 1 As shown, the invention provides a kind of high-density crayfish cultivation method, and concrete steps are as follows:

[0024] S1. Reserve shrimp seedlings: prepare healthy wild crayfish as shrimp seedlings, and disinfect them with iodine solution;

[0025] S2. Arranging the breeding site: use ponds, rice fields, barren beaches and pit ponds for breeding, with an area of ​​2400 square meters, and set up anti-escape boards to prevent lobsters from escaping. The height of the anti-escape boards is 0.5m, and the inner wall is smooth and flat. The width of the surrounding ridge is 1.5m, and the injection and drainage systems are built;

[0026] S3. Preparation for stocking: tidy up the pond, remove silt and level the bottom of the pond, increase the water retention performance of the bottom and wall of the pond, reduce water leakage, and use quicklime to clean the pond for disinfection. The amount of fresh quicklime is 125 kg / mu , the whole p...

[0039] Example 3, such as figure 1 As shown, the invention provides a kind of high-density crayfish cultivation method, and concrete steps are as follows:

[0040] S1. Reserve shrimp seedlings: prepare healthy wild crayfish as shrimp seedlings, and disinfect them with iodine solution;

[0041] S2. Arranging the breeding site: use ponds, rice fields, barren beaches and pit ponds for breeding, with an area of ​​3000 square meters, and set up anti-escape boards to prevent lobsters from escaping. The height of the anti-escape boards is 0.5m, and the inner wall is smooth and flat. The width of the surrounding ridge is 1.5m, and the injection and drainage systems are built;

Abstract

The invention provides a high-density crayfish breeding method, and relates to the field of crayfish breeding. The method comprises the following specific steps: S1, storing shrimp larvae; S2, arranging a breeding site; S3, performing stocking preparation; S4, stocking shrimp larvae; S5, feeding feeds; S6, performing water quality management; and S7, fishing and marketing finished products. Healthy wild crayfishes are prepared as crayfish larvae, the crayfish larvae are disinfected by using an iodine solution, a pond is arranged, then the pond is cleaned and disinfected, besides, during water quality management, the aeration intensity is increased, the dissolved oxygen of the pond is kept to be more than 5mg/L, water is changed once every 15-20 days, 1/2 of the water is changed every time, quick lime water is splashed once every 20 days, and about 10 kg of quick lime water is used for adjusting the water quality per mu every time. According to the high-density crayfish breeding method, the occurrence of a phenomenon that a large number of crayfishes fall ill and are dead is avoided, and the occurrence of huge economic losses of farmers due to the death of a large number of the crayfishes is prevented.

Description

technical field [0001] The invention relates to the field of crayfish cultivation, in particular to a high-density crayfish cultivation method. Background technique [0002] Crayfish is a kind of freshwater economical shrimp. It is widely welcomed by people because of its delicious meat. It has an absolute competitive advantage in the local ecological environment because of its omnivorous nature, fast growth speed and strong adaptability. Crayfish has become an important food in China in recent years. economically farmed species. [0003] In the traditional crayfish farming, due to improper breeding methods, the oxygen content in the ponds in the breeding waters decreased, which caused the phenomenon of crayfish grazing and beating in many ponds. At the same time, the overall death rate of crayfish was large. After the crayfish are sick and dead, the crayfish will eat each other, which will induce or aggravate the disease, and cause a large amount of economic losses for the...
