What bait is good for fishing in rural rivers?

Fishing in rural rivers is good for earthworms.

Earthworms, also known as earthworms, are terrestrial invertebrates of Oligochaeta in annelids. Earthworms are one of annelids. There are more than 3,000 kinds of earthworms in the world, and there are more than 200 kinds in China. There are earthworms, Eisenia foetida, earthworm with different lips, earthworm with dura mater, etc. Widely distributed in China.

Earthworms are rich in nutrition, rapid in reproduction, miscellaneous in feeding habits and high in artificial breeding yield. Good economic benefits. Earthworms can be used as precious drugs to treat many diseases, and also as high-protein food and feed. Earthworms dig holes to loosen soil and decompose organic matter, which creates good conditions for the growth and reproduction of soil microorganisms and plays an important role in improving soil, eliminating public hazards and protecting ecological environment.

It plays a special role in material circulation and biodiversity. Many countries use earthworms to treat domestic garbage, organic waste and purify sewage. Earthworms contribute to material circulation and energy transfer in soil process by feeding, digesting, excreting (earthworm dung), secreting (mucus) and digging holes.

It is one of the soil invertebrates (mainly earthworms, mites and ants) that have an important influence on many processes that determine soil fertility, and is called "ecosystem engineer". The body is segmented without division, the wart foot degenerates, and the body surface has bristles. Androgyny, gonad 1-2 pairs, the reproductive duct originated from the body cavity, and a reproductive belt appeared on the body surface during sexual maturity.

When mating, they can inseminate each other, and the eggs are produced in the ring belt, and after shedding, they form egg cocoons and develop directly. The setae are solitary, 8, sometimes many, arranged in a ring shape, with 1-2 pairs of testis, usually at10-1node, and a pair of male reproductive pores, which are located on two or more somites behind the posterior testis, namely/kloc-0. A pair of ovaries, located at 13, have thick bands and few yolk.

Earthworms have been identified by karyotype analysis in China. Chromosome 2n=22 of Eisenia foetida is exactly the same as that of artificially raised earthworms "Taiping II" and "Beixing II". The body wall structure consists of cuticle, epidermal cells, annular muscle and longitudinal muscle, and the muscle layer is the body cavity membrane. There are well-developed glandular cells in epidermal cells, which can secrete mucus to moisten the skin and facilitate movement in the soil.
