Technical Field

The invention relates to the field of crayfish breeding, in particular to a crayfish fishing device.

Background

The crayfish is named as procambarus clarkii in science, and most of crayfish on the market are artificially cultured in a pond with clean water in order to meet the market demand and ensure the quality of the crayfish. The existing method for catching crayfish is to sink a ground cage net into a pond so that the crayfish climbs into the pond from an inlet of the ground cage net, take the ground cage net out of the pond after waiting for a period of time, and pour the crayfish out of the ground cage net. In the process, the crayfish is easily accumulated at the bottom of the ground cage net, so that the crayfish is dead.
