The main method of river shrimp fishing is to use the ground cage, and the mesh size of the ground cage should be about 1cm to ensure that only the adult shrimp are caught and the young shrimp can swim out through the mesh.

Method of catching shrimp: With the help of the principle of lighting, shrimps are caught together, just like flying insects at night. On a hot summer night, when a flashlight is used to illuminate the water, shrimps jump to the light and come together soon.
