How to match wild shrimp with bait?

River shrimps rarely move on the shore during the day, but at night, there will be a large number of shrimps foraging on the rocks on the aquatic plants on the shore. Shrimp cages can be used to catch river shrimp, but fishermen don't specialize in catching shrimp, and there are few shrimp cages. What shall we do? We can catch shrimps with nets. We can make some fishy bait with fine mesh, make it hard and sticky, put it in the net, and immerse the net in the water with many shrimps on the shore. It won't be long before the river shrimp will be eaten in the net. All you have to do is pick it up quickly.
