Farmers in rural areas usually use idle water tanks to plant lotus roots or breed some small crucian carp they catch themselves.

As we all know, crucian carp is an omnivorous fish. Its diet includes: earthworms, maggots, mosquito larvae, small insects, stems, leaves and roots of aquatic plants, flower petals falling into the water, rice, rice, and wheat. Wait, wait, whatever is edible, it can eat.

Farmers living in the countryside and friends who love fishing all know that in spring and summer, when walking along the ditches and rivers in the countryside, you will always hear the sounds of "bagu, bah" coming from the aquatic plants on the water surface. The sound of gurgling means that crucian carp is floating on the surface of the water and eating the tender stems and leaves of aquatic plants.

As for the vitality of crucian carp, not many people know how tenacious it is!

It can be said that crucian carp cannot survive except in water containing highly toxic chemicals! As long as there is water, there will almost always be crucian carp!

Why do you say that?

Beside the Longmian Avenue subway station in Jiangning District, Nanjing City, there is a small smelly river. Once after the subway arrived at the station, when I went to the smelly ditch for convenience, I found that there was a small smelly river. In that little smelly ditch, there was actually a large group of small crucian carp floating with their heads sucking oxygen!

Also, in front of my home, in the 2000s, a small pond with only about two acres of land was picked out to build the embankment of the Qinhuai River. It was also raised for several years at that time. Fish, but later it was completely covered by bad weeds, water peanuts, and the longer it grew, the thicker it became. Even if a person stood on it, it would not sink! It also emits a strong stench. Logically speaking, except for some eels, there will be no fish inside!

But one day when I was under the wild rose bushes, I actually saw some small crucian carps floating on their heads! At that time, I really sighed that in this kind of smelly waters with no food and no oxygen, it could still survive. This shows that the vitality of crucian carp is extremely tenacious!

So regarding the question asked by the questioner, in rural water tanks, we often see farmed crucian carp, but they are never fed, but the fish will not starve to death?

The scene of swimming in the fish, and crucian carp is an omnivorous fish, so mosquito larvae just become their snack.

Second, every summer in rural areas, there are a lot of various insects. Such as: fireflies, seven-star ladybugs, flying ants, moths, etc., as long as they fall into the water in the tank, they will become the delicacies of crucian carp.

Third, when the water in the tank is stored for a long time, because it is a pool of stagnant water, bathing species, such as moss, will slowly grow. Crucian carp can eat moss to satisfy its hunger without starving to death. .

Fourth, when farmers take water from natural waters to raise crucian carp, there are many microorganisms and microorganisms in the natural waters, so they also fill the belly of the crucian carp. Even if they are not fed, the crucian carp will not Starved to death!
