Description
Technical Field
The invention relates to the technical field of crayfish breeding, in particular to an industrial crayfish breeding pond.
Background
At present, the main breeding mode of crayfishes is pond breeding or paddy field breeding, and the crayfishes have the advantages of large foundation area and low management intensity. But also has more problems, firstly, the size of the fries on the market is large, the shrimp fries with the weight of more than 4g can be caught by adopting a cage catching mode, the catching rate is not high, and the fries need to be repeatedly placed in cages for long-term catching; secondly, the breeding time is long, the adult shrimps grow seedlings intermittently from 6 months to 11 months, and then the seedlings grow continuously from 11 months to 3 months in the next year; thirdly, the survival rate of the seedlings is low, and the rate of emergence is lower than 30 percent in the growth process due to self-residual, predation of natural enemies, catching damage and the like. In the industrial breeding mode, the seedlings can be captured in batches and fished out of the pool after leaving the parent body for about 10 days, the specifications of the seedlings are regular, the rate of emergence can reach over 80 percent, the autumn seedlings can be cultivated in winter in subtropical regions, and the off-season marketing is realized, so that the method has a good industrial prospect. At present, the industrialized breeding research of crayfish has been carried out in Hubei province and Jiangsu province, the crayfish parents are subjected to intensive cultivation and concentrated egg-holding, the matched parent crayfish is placed in a parent cultivation pool 30 days before 9 months, the cultivation density of the parents is 40-50 per square meter, and the egg-holding rate of female crayfish can reach 60-70% after the crayfish is subjected to intensive cultivation for 30-40 days by adopting special feed. And putting the female shrimps with the eggs into a breeding pool for breeding. However, the above-mentioned industrial breeding method still has several problems: firstly, the gonad development stage of the crayfish is difficult to accurately judge, the mating breeding shrimps can be cultured in a workshop, the female shrimps with the eggs held in the belly are selected and placed in a seedling raising pool to obtain the synchronously hatched fries, but the accurate selection of the eggs-holding shrimps needs higher technical experience and labor intensity, otherwise, the egg-holding shrimps are missed to be selected or the egg falling phenomenon is caused; and secondly, the crayfish has low egg holding amount, a large amount of breeding shrimps are needed, the space occupied by breeding the breeding shrimps is more than half, and the breeding cost is doubled.
