After the emergence of commercial baits, the use of earthworms has become increasingly rare. However, when fishing in some wild waters, the fishing effect of earthworms is even better than that of some commercial bait, especially for some elderly anglers who go out fishing and usually equip themselves with earthworms. Earthworms mainly fish for crucian carp, yellow catfish, catfish, etc. Of course, other freshwater fish such as carp and grass carp also eat earthworms. This column collects the basic techniques of using earthworms for fishing, including simple cultivation techniques for earthworms, illustrations of adjusting the float for earthworms fishing, and what to use for making nests when using earthworms for fishing.
