Problems solved by technology

[0005] In order to solve the above-mentioned shortcomings, the present invention provides a method for temporarily raising Chinese mitten crab commercial crabs in winter, which solves the problems of the existing Chinese mitten crab commercial crabs, such as the short edible period, centralized listing, etc., which cause sales difficulties and low sales prices, and the temporary cultivation in traditional ponds. The method causes problems such as high mortality rate, small amount of temporary breeding, and difficult fishing. Through this breeding method, the survival rate of temporary breeding in winter can be improved, the number of temporary breeding per unit can be increased, and the difficulty of fishing can be reduced, so as to achieve off-season sales and improve the farming economy of farmers. benefit purpose
