What is the reason for the crucian carp caught in an abandoned pond with particularly long tails?

As a fisherman who loves wild fishing, he usually either looks for wild fishing spots or investigates wild fishing spots. Friends who often go wild fishing should know the sadness involved. They may find ten to eight fishing spots.

Only one or two fishing spots will produce good results. Therefore, wild fishing is basically ten fishing and nine empty fishing spots. Yesterday went to develop a new fishing spot, an abandoned wild pond on the outskirts, which is cheaper.

There should be fish visually, but no one knows if I can catch a fish before I fish. After paying the price of sweat, I opened up a fishing spot. After spilling rice wine, I started fishing.

It's not that I don't want to make a nest. The main reason is that I'm not very sure about the fish and it's not easy to target the nest. Earthworm.

It is used as bait.

When you're unsure about the fish, earthworms are definitely the best bait. Ten minutes later, there was a mouth and a small crucian carp was placed on the rod. At that time, I noticed that this small crucian carp was a little different from the crucian carp I usually caught.

The tail is relatively long, similar to the tail of a goldfish I usually see. However, it's normal to occasionally encounter strange-looking fish, so I didn't pay much attention to the first one. Later, I found out that the crucian carp caught in this wild pond are all like this, I don't know why?

First of all, before choosing a fishing location, it is best to observe the nearby water surface to see if there are any ripples, waves and flips. If there is, then we need to look in more detail to see if it is caused by wind. If not, once, go fishing in an unfamiliar reservoir.

I arrived around 10 am in the summer. At first, I noticed ripples on the water from a distance, but there was no wind at that time. Then I quietly approached. As a result, a closer look revealed more than a dozen bighead carp.

Deflated on the water. The mouth is estimated to be able to stuff a human head into it, and it is estimated that it is more than 230 catties. It's a pity that there was no suitable fishing gear at the time, otherwise I would have to follow this.

The big fish fought. If the target fish for this trip is not pelagic species, then we can use other methods to determine if there are fish at the bottom of the water and continue to look down.

It seems that the scales of these crucian carp are not much different from ordinary wild crucian carp, except that their tails and fins are different, and they are all very long. Could it be that someone has spared the goldfish here before, and these crucian carp caught are the common offspring of goldfish and wild crucian carp? I don't know if this crucian carp can be eaten!

Some of them are quite large. The largest ones have about three or two. In the end, they caught about 30 fish.

It's not explosion-proof protection, but for wild fishing, the harvest is good.

Thin. There was no food to eat in the pond. The same is true for raising goldfish, the goldfish that are fed are butterfly tails, and the goldfish that are not fed have longer tails, which are called skirt tails.

Or is it because the environment inside the pond is suitable for their growth, and there are many aquatic plants in it, so their tails are particularly long, which is a normal development.

This is because these crucian carp are affected by pollutants in this abandoned fish pond, so their bodies have undergone particularly serious mutations.

It may have a lot to do with the environment in which these fish grow, so their appearance has changed, so this fish should not be eaten again.

It's because it's a species of crucian carp, and there are very few people who breed it, because the income of this crucian carp is very low, so no one breeds it.
