Catfish are omnivorous fish, small fish and shrimp, small creatures in the water, silt and so on, so some people who catch catfish use sea silkworms, and some simply use dough to catch them. In order to lure catfish together, many people make a nest before fishing, that is, throw rice, steamed bread and dough into shallow water to lure the fish to the bait, and then bait them. In this way, they can catch fish easily.
