It is a freshwater shark that can't get enough to eat 30 years ago, but it bothers Americans.

No matter which species lives in the world, there will be a few particularly strange species. For example, among the fish, there is such a kind of fish, which does not look handsome, is not huge, has no teeth and claws, and does not discharge or poison, but it is such a fish that can eat all the fish in the water wherever they go. You heard right, it is the fish in the whole lake, their appetite is unusually big, and they are ferocious. They are "black fish", and they have a terrible reputation as "freshwater sharks" among the fish.

It also has a special skill, that is, it can wriggle and glide on the ground in order to find new rivers. After all, they are so edible that a lake can't feed them for long. And they can also be "amphibious", leaving the water can survive for three days, the vitality is inconceivable. Black fish is a very common fish in China, its individual is large, the growth rate is fast, it can grow 15 centimeters long every year, the average weight is about 2 kilograms, as an aquaculture economy is huge, there are many farmers in our country to raise black fish as the main business.

The body of the black fish has snake-like spots, which is unique in the fish and is easy to distinguish. About 30 years ago, aquaculture was underdeveloped, and most of the fish on the market were wild fish, of which blackfish were the most common in rural rivers. In the dry season of autumn and winter every year, you can get a lot of fish in the river. When you were a child, you ate a lot of black fish roe. Earlier also said that black fish eat all kinds of fish, is extremely ferocious carnivorous fish, so its taste is delicious, nutritious, the previous rural women milk is to eat black fish, drink black fish soup.

Blackfish is distributed in all major river systems in China, followed by Japan and North Korea. Americans have also introduced blackfish. After it took root in the United States, it once became a nightmare for Americans. First of all, there are two points: their appetite is too big, so once they enter the fish pond, the fry basically become their midday meal, and the speed of reproduction is fast, so it is very difficult to expel the black fish. Secondly, the black fish will eat everything, and the same kind will also eat. It is even called the dirtiest fish in the world. Americans are used to eating marine fish, but they will not eat this kind of freshwater fish. In order to get rid of the blackfish, the Americans racked their brains and mobilized the public to kill the blackfish as soon as they saw it, but it still did not change the fact that the blackfish was rampant.

In the eyes of Americans, blackfish is not only a "freshwater shark", but also a monster. It is said that it can not only eat other fish, but also eat pets and even humans (of course, this must be false). The Americans also made a movie, in which the monster is the black fish, which deepens Americans' aversion to the black fish. In fact, black fish is not so scary, it is extremely delicious in our country, the price is 20 yuan a kilogram, if Americans come to taste our country's braised black fish and boiled black fish, then maybe the black fish will be eaten by them!
