Two-purpose pond for breeding and cultivating procambarus clarkii

Abstract

The invention discloses a two-purpose pond for breeding and cultivating procambarus clarkii, and relates to the technical field of procambarus clarkii breeding. The two-purpose pond comprises a breeding pond, a culture pond and a round pipe; the depth of the breeding pond is smaller than that of the breeding pond, and the breeding pond is fixedly arranged and close to the culture pond; a slope isfixedly arranged at the bottom of the breeding pond, and the lower end of the round pipe is vertically and fixedly arranged on the slope; the upper end of the round pipe is provided with an opening, and the upper end surface of the round pipe is flush with the upper end surface of the culture pond; the lower part of the round pipe is provided with a through hole, and the breeding pond communicateswith the culture pond pass through the round pipe; therefore, the defects that existing procambarus clarkii mixed culture can cause disputes and cannibalism among procambarus clarkii at different growth stages, and thus, low yield of the procambarus clarkii is caused are overcome, and a breeding process and a culture process of the procambarus clarkii can be separated to increase the yield of theprocambarus clarkia, and the disease resistance of the procambarus clarkii is improved.

Description

technical field [0001] The invention relates to the technical field of Procambarus clarkii culture, in particular to a dual-purpose pond for breeding and cultivating Procambarus clarkii. Background technique [0002] The scientific name of crayfish is Procambarus clarkii. The distribution of crayfish farming in my country is extremely unbalanced. Only 18 of the country's 30 aquaculture areas breed Procambarus clarkii. The region with the largest aquaculture output has the total annual output of crayfish in 2017. It is 631,621 tons, which is 133,504 tons more than the total output of other Procambarus clarkii producing areas in the country, accounting for 56% of the national Procambarus clarkii production, followed by Hunan and Anhui Procambarus clarkii production accounting for 12% of the country. The production of Procambarus clarkii accounts for 10% of the national output, the output of Procambarus clarkii in Jiangxi accounts for 7% of the national output, and the output of ...

[0002] The scientific name of crayfish is Procambarus clarkii. The distribution of crayfish farming in my country is extremely unbalanced. Only 18 of the country's 30 aquaculture areas breed Procambarus clarkii. The region with the largest aquaculture output has the total annual output of crayfish in 2017. It is 631,621 tons, which is 133,504 tons more than the total output of other Procambarus clarkii producing areas in the country, accounting for 56% of the national Procambarus clarkii production, followed by Hunan and Anhui Procambarus clarkii production accounting for 12% of the country. The production of Procambarus clarkii accounts for 10% of the national output, the output of Procambarus clarkii in Jiangxi accounts for 7% of the national output, and the output of Procambarus clarkii in Shandong and Sichuan accounts for 1% of the national output. Procambarus clarkii in other production areas such as Guangxi, Guizhou, and Yunnan The output is close to 0% compared with the national total output, and the reason for the low crayfish output is that the seed technology is not yet fully mature, and the existing technologies for raising Procambarus clarkii are mainly rice shrimp comprehensive breeding, pond Shrimp and crab mixed culture, pond main culture, lotus root pond culture, beach land augmentation culture, etc. failed to realize large-scale culture

Especially the polyculture of crayfish in different growth stages will lead to easy fighting and cannibalism between crayfish, which will lead to a decline in crayfish production
