If the crayfish is cleaned, it can live for 5- 10 days by directly pouring it into a pool or a glass jar for oxygenation and changing the water twice a day.

Generally speaking, crayfish can be cleaned with water, then put into a basin, poured with appropriate amount of cold water, completely immersed in crayfish, and then frozen in the freezer. It is also good to take out the basin after freezing, put it outside for a while, dump the frozen shrimp pieces, seal them with fresh-keeping bags or plastic food bags, and store them in the freezer.

Crayfish culture: crayfish can be caught and sold ashore in autumn. In the process of fishing, it is necessary to leave some healthy shrimps for natural mating in August-September. During the breeding period, the water level should be lowered and holes should be dug for crayfish to lay eggs.
