Earthworms don't live underwater, so why use them as bait? Does the fish really like to eat it?

The earthworms we usually catch don't live in water. Actually, earthworms don't like water. You see it lying on the ground in a rainstorm because the earthworm can't breathe because the soil is soaked in rain, so it ventures out to breathe. Usually underground.

Looking around, it is difficult for fish and earthworms to meet in any surrounding lake. It is really difficult for two kinds of creatures to mix together except for two special cases: rainstorm scouring and artificial introduction. But people like to use earthworms as bait. Do fish really like to eat this once-in-a-lifetime biological earthworm? Or is there any scientific truth in this?

Summarize the following three points: appearance, economy and sports.

(1) Appearance: Through a lot of observation and research, although fish can't contact earthworms without interference in water, similar creatures will also encounter them. Besides, most fish are not picky eaters. Like catfish, it will choose dead insects, insect larvae lipid things, which looks like earthworms.

So there is a certain chance that the fish may be mistaken, thinking that it is not an earthworm, but a delicious worm.

(2) Economy: Generally speaking, the fish in the water are always tired of eating food, so it is necessary to change a good amount of bait. So earthworms were discovered by people, because there are many on the earth. And it is economical. When the fish suddenly see this creature with great freshness, they can't wait to swim over, and those who are willing will take the bait.

(3) Exercise: I agree with this. Earthworms are a good choice, or it may be because they struggled hard before drowning, which made the smell of blood spread rapidly and attracted fish. Studies show that fish like moving objects. If there are two choices: dead worms and live worms, most fish will choose the object they have chosen. So earthworms are capable.

Speaking of which, you may think that fish don't necessarily prefer earthworms. Indeed, there are many factors that affect the use of earthworms as bait. Either one makes sense, or I hope everyone will look at three points comprehensively. Perhaps, fish have a natural preference for the smell of earthworms, but it is difficult to meet them at ordinary times.
