Description
Technical Field
The invention relates to the technical field of aquaculture, in particular to a crayfish efficient breeding method with coupled breeding and breeding.
Background
Crayfish, the academic name procambarus clarkia: (Procambarus clarkii) In the last 30 th century, Nanjing was introduced from Japan, and the Nanjing has spread throughout the great rivers, the south and the north of China at present, and becomes an important special aquaculture variety. At present, the comprehensive crayfish breeding mode is popularized in large scale in various places of China, but a plurality of problems still exist in production, and the yield, the quality and the benefit of the bred crayfish are seriously influenced.
The close breeding phenomenon of the breeding crayfishes of the bred crayfishes is serious. At present, the simple and laggard mode of 'grabbing big and leaving small' is still adopted for crayfish breeding in production, so that the crayfish 'in the three generations of the same hall' is commonly found in breeding ponds, and the probability of close reproduction is extremely high. Most of the cultured old pond mouths depend on the self-propagation and self-breeding of the shrimps in the original pond mouth, the germplasm degeneration is serious, the offspring seed yield is unstable, the survival rate is low, and the improvement of the quality and the culture benefit of the cultured commercial shrimps is seriously influenced.
The survival rate of crayfish fries bred at the mouth of a new pond is reduced due to transportation stress. At present, the artificial breeding technology of crayfish fries is not completely mastered by farmers, and particularly, the fries need to be conveyed from a production area by new farmers. However, from the view of the current transport apparatus and vehicles, the related facilities and equipment are not professional, and the transport distance is long, so that the stress response of the crayfish is frequent, and the survival rate of the crayfish after the crayfish is put into a new pond is low. Researches show that the fry transportation time is 3 hours, the survival rate is only about 60 percent, and the longer the transportation time is, the lower the survival rate is.
The specifications of the cultured shrimps have large difference. The crayfish is bred by self-reproduction and self-breeding and the crayfish is grabbed to be big and left small, so that the old crayfish, the young crayfish and the young crayfish exist in the same pond, and the phenomenon of the same cage for the third generation is caused during fishing. If manual sorting is not carried out, the selling price of the bulk goods is extremely low, and if manual sorting is carried out, the cost is increased, so that the benefit is influenced; if the captured weak shrimps or young shrimps are put back to the pond again for continuous culture, most of the weak shrimps or young shrimps die after long residence time and large stress reaction in catching tools such as ground cages and the like, even the diseases are caused and spread, and economic loss is brought to farmers.
In recent years, the crayfish industry develops rapidly, researches on modes such as rice shrimp co-culture, lotus root shrimp co-culture, pond main culture and fish and shrimp co-culture are carried out, and cultivation technical researches such as 'breeding separation' and 'stubble cleaning' of crayfish are also carried out gradually aiming at the problems of crayfish close-up breeding, germplasm degradation and the like. The achievements play a certain positive role in improving the quality of the crayfish germplasm, increasing the yield and the like, but the systematic breeding technology of the crayfish seedling-shrimp-seed is not reported yet. In the prior art, how to fully utilize different breeding modes and carry out organic linking, realize the deep combination of local-production seedlings and local breeding, and improve the yield and the quality of crayfish is a problem which needs to be solved at present.
