Crayfish breeding method

Abstract

The invention relates to the technical field of crayfish culture, and discloses a crayfish breeding method. The crayfish breeding method comprises the following steps of thoroughly cleaning a pond toachieve no grass and no trash fish. According to the crayfish breeding method, a mode of one cage and one crayfish is arranged, the product is designed according to the living habit of the crayfish, the crayfish is prevented from death due to mutual attack, the problem that grass exists in a pond and water culture is difficult is solved, fertilizer and water are mixed with feed for breeding in thewhole process, and the crayfish breeding cage does not need to be fixed, so that the breeding cage is always located on the water body, and less bacteria and high oxygen are achieved, so that the problem that the mortality rate of bacterial infection of the crayfish in the shelling period is high can be solved, the growth speed is high in the resting environment, the growth speed and survival rate of the crayfish can be visually observed, the problem that the crayfish cannot be manually controlled in the breeding and fry raising process is comprehensively solved, and the crayfish can be caught all the year round; and the problem that the crayfish can only be fished seasonally is solved, the survival rate and the living environment of the crayfish can be improved, and breeding of the crayfish is facilitated.

Description

technical field [0001] The invention relates to the technical field of crayfish cultivation, in particular to a crayfish cultivation method. Background technique [0002] Crayfish, also known as Procambarus clarkii, is a very favorite table food for Chinese people. Previously, crayfish belonged to the United States, and then it was introduced to China through Japan. Since it was introduced to China, it has been loved by many people. Because of the production of crayfish Strong ability, high nutritional value and delicious taste are loved by the market, so many people gradually start farming. Crayfish have strong adaptability to the environment and can grow in various water bodies such as lakes, ponds, river ditches and rice fields. Water sources To be sufficient, the water depth is about 1 meter, the pond must have sufficient water source, good water quality, and convenient water intake and drainage. [0003] The existing traditional crayfish breeding is prone to disease an...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a crayfish breeding method, which has the advantages of avoiding soil erosion, etc., and solves the problem of the existing traditional crayfish farming, which is prone to disease and death, has low yield and no guarantee, and has strong seasonality in starting and laying. It is time-consuming and labor-intensive, and the habit of attacking each other during the shelling period cannot be artificially controlled. Due to the habit of crayfish digging holes, it is highly destructive to the embankment. The reason for the habit makes the crayfish need to plant grass in the shelling period, but the grass absorbs fertilizers at the same time. It also caused the imbalance of microorganisms in the water body ecology
