High-density crayfish breeding method

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...

[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 become sick and die, the crayfish will eat each other, which will induce or aggravate the disease and cause a lot of economic losses for the farmers.
