Fishing is not allowed during the fishing ban in the Yangtze River, will the fish flood? How big will the biggest fish be in ten years?

Many people say that the species in the Yangtze River was particularly rich in the past, and the fish in the Yangtze River can also allow people to rely on the Yangtze River to survive.

But now human beings have become more and more " capable ", directly exterminating the offspring of fish, not only adult fish are caught, but even some smaller fish are directly caught , and many fish are directly cut off offspring.

In order to avoid the problem of fish dying off offspring, a fishing ban has been established since 2003 , although there are several months of fishing every year .

However, when fishing starts, the fish will be allowed to return to before liberation overnight . During the few months of the fishing ban in the Yangtze River, it is not easy to directly reproduce the population .

In the past, the Yangtze River was the cradle of freshwater fish , but I never thought that there is no better fish cradle in the Yangtze River now .

In the past, the Yangtze River was rich in species resources, but now there are more and more wild animals in the Yangtze River. It is because people are too "capable" that they are directly caught and disappeared. The most important thing is that some fish are directly caught and announced. Extinction.

The previous Chinese sturgeon and Yangtze finless porpoise were relatively easy to see fish , but it is impossible to see them now. In order to avoid the problem from becoming more serious, there is now a fishing ban period in the Yangtze River .

And this fishing ban is not a few months, but a 10-year fishing ban , which is to allow the creatures in the Yangtze River to have a longer time to complete the restoration .

Many people want to know why the Yangtze River needs to restore species . Some experts say that if the species in the Yangtze River becomes less and less, there may be no fish to eat .

Many people want to know that most of the fish today are not caught in the wild , but are artificially farmed. Why do they say that there are no fish to eat?

It is because the genes of the fish will be degraded when the fish is artificially raised. The wild fish is a gene pool. If all the wild fish disappear, it is impossible to artificially raise them.

In the process of artificial breeding, the genes of the fish will become worse and worse . If in the process of artificial breeding, coupled with fewer and fewer fish in the wild, in the long run, it is indeed possible to achieve zero The fish is edible .

From the perspective of the general environment, if too many fish are caught , it will also affect biodiversity. Although for us, it feels like 10 years is a long time, but for fish, it is also necessary to repair the problem of breaking the food chain. Not very easy.

For the fishes in the Yangtze River, it is very likely that they can reproduce only two or at most three generations when they reproduce . For some fishes that reproduce for a long time, it is very likely that they will only reproduce one generation in 10 years. .

After the Yangtze River fishing ban was introduced, it has been implemented for more than a year. Although it has been implemented for more than a year , many people say that what kind of problems will arise in these 8 years.

Fishing is not allowed during the fishing ban period , which shows how much effort has been made to change the ecological environment of the Yangtze River this time .

Although the fishing ban period has begun, it is not easy to increase the number of species rapidly . After all, there is a food chain in fish, and high-level fish will eat low-level fish. It can only be said that species in a certain link There will be no explosive growth.

If you want to know whether the Yangtze River can be restored to the state of a hundred years ago after the fishing ban period, but now, even 10 years later, it is not .

Although it has been implemented for more than a year, it has shown a relatively good situation , but after 10 years, there will be relatively novel results, and I don't know what the final results will be .
