Problems solved by technology

[0004] For this reason, the embodiment of the present invention provides a method for breeding crayfish in paddy fields suitable for the northern region, so as to solve the transportation process caused by the lack of crayfish seedlings in the northern region because the seedlings need to be transported from the south in the existing crayfish farming technology. There are a large number of deaths in the plant, and the southern seedlings are not suitable for the northern environment, etc.

Abstract

An embodiment of the invention discloses a crayfish rice field breeding method suitable for Northern areas and relates to the technical field of aquaculture. The method includes following steps: selecting and planning a rice field, free-ranging aqua-plant cultivation parent crayfishes in the rice field, inducing mating and spawning of the parent crayfishes, performing shed buckling treatment through circular grooves, and culturing seeds. Technology of inducing mating and spawning of the parent crayfishes and technology of shed buckling treatment through the circular grooves is adopted in the process of crayfish breeding, the method plays a quite important role in crayfish rice field breeding in the Northern areas, crayfishes obtained by breeding are high in total yield and survival rate, the problem of deficiency of crayfish seeds in the Northern areas can be solved effectively, and the defect that non-local crayfishes are high in death rate and low in adaptability is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of aquaculture, and in particular to a paddy field breeding method suitable for crayfish in northern regions. Background technique [0002] In 2018, China's crayfish (Procambarus clarkii, Procambarus clarkii) industry accelerated its development. The aquaculture area exceeded 16 million mu, the output exceeded 1.6 million tons, and the total economic output value exceeded 360 billion yuan. Crayfish farming has become one of the main models for the development of ecological circular agriculture, and it is the most dynamic, potential and characteristic sunrise industry in the new era to accelerate the green development of fishery. [0003] At present, there is a huge gap in the crayfish market at home and abroad. Crayfish are mainly cultivated in the southern region, while the northern region has not been able to form large-scale farming. The seed can only be transported from the sout...
