When we used to do physics experiments, we used to use weights to contribute to a balance being in equilibrium. As long as both sides of the balance have equal mass, then it will remain in balance, and if one side is slightly different, then the balance will be broken. In fact, there are many areas that are just like a balance, if the balance is disturbed, then it will have a very bad effect, such as the ecological balance of the biological world.

In the 21st century, there are 10 "invasive species" in the world, including the snakehead fish. Speaking of snakeheads may not be very familiar with the guys, but if you talk about blackfish, snakeheads, perhaps people will not feel strange. 21st century, today, snakeheads in our country's market everywhere, the very best-selling it belongs to the 1 kind of mainstream fish, but also for a lot of people to bring a lot of economic benefits, half of them are not more than three pounds or so.

As for the origin of the snakehead fish seems to have no evidence, but in many parts of the country are widely distributed. But what's more interesting is that it has also made its way to the United States, where it has even become ubiquitous, giving the U.S. a headache.

Since 1945, the United States has become the world's No. 1 power. They are leading the world in economy, military, science and technology, plus the vast area of the U.S. mainland, so this country is also very rich in species. In many lakes in the US, at some point the snakehead fish settled there.

The snakehead is so strong that it can survive for up to three days without water. These are not enough, the snakehead fish itself is very fierce, few other fish can threaten its survival; on the contrary, they are mainly "meat", freshwater fish and shrimp have become its meal.

Data shows that since the snakeheads began to proliferate in U.S. lakes, the size of these guys has been growing like crazy, and 20 pounds of them are everywhere, and there are even bigger ones than that. As has already been said, if the ecological balance is disturbed, then it can have a nasty effect as well.

And this invasive species has made it so that the native fish and shrimp in the American lakes have become unviable, while snakeheads have begun to proliferate. Many people were forced to run into the lake periodically to clean it up, but it didn't seem to have much effect. By the time 2020 rolled around, the United States was really kind of burned out by snakeheads. It turns out that Americans don't like eating snakeheads as much as our residents do, and instead there's even an aversion to it.

This is why? It turns out that snakeheads are ugly, and they often appear in horror movies, so the U.S. residents are even more reluctant to eat it. But in China, snakeheads are basically everywhere, and they only weigh about 3 pounds. That's a pretty big difference in attitudes toward snakeheads between the U.S. and China!
