Background
Procambarus clarkia (C. clarkia)Procambarus clarkii) The crayfish is commonly called freshwater crayfish, belongs to Crustacea, decapetalous order, crayfish family, procambarus, is originally produced in North America, is introduced into the Chuzhou region of Jiangsu Nanjing and Anhui of China in 1929 from Japan, has strong adaptability, large fertility and wide eating habits, and becomes one of the important freshwater economic crayfish of China after dozens of years of natural propagation and artificial introduction and culture. At present, in the traditional technology for producing the Procambrus clarkii spawning shrimps, a field soil pond breeding method is mostly adopted, the method of gradually lowering water is adopted along with the temperature reduction from the beginning of 10 months to the beginning of 11 months every year, most of the Procambrus clarkii are gradually induced to enter a cave to spawn and spawn, most of the produced spawning shrimps inhabit the cave in a field soil pond, the recapture difficulty is large, the gonads of the Procambrus clarkii are unsynchronized in gonad development, so that the hatched shrimp larvae are irregular in specification, large and small shrimps and the same pond are formed, the small shrimps are easily eaten by residue, the seedling rate is low, and the problem of shortage of high-quality Procambrus clarkii seedlings in China is not solved so far in the field.
As an improvement, the procambarus clarkii oviposition shrimp is produced by adopting a cement pond to replace a field soil pond and adopting waterweeds, meshes, bricks, tiles, old tires, PVC pipes and the like as concealed objects. However, the technology has disadvantages in practical production: aquatic weeds are easy to eat by parent shrimps and die, and the dead aquatic weeds easily spoil the water quality, so that the death rate of parent shrimps in cultivation is high, fertilized eggs of egg-carrying shrimps easily mildew and the like; the shading effect and stability of the meshes and the PVC pipes are poor; hidden objects such as bricks, tiles, old tires and the like are arranged with strong randomness, and a certain stable and practical structure is not formed; the defects of the concealed objects cause the egg laying rate of the Procambrus clarkii produced by the cement pond to be low.
