The news of the Asian carp flood in the United States has been going on for a long time, and the US government even wanted to introduce alligator eels to eliminate Asian carp, but the local fish suffered and the Asian carp survived better.
Dense-phobia don't look
The entry of Asian carp into the United States has to start from the last century, in the fifties and sixties of the 20th century, the United States economy developed rapidly, and a large number of factories were built around the Mississippi River. The ensuing large amount of sewage is discharged into the river, the heavy metals in the water body exceed the standard, and the water body is eutrophic. As algae bloom and native fish die in large numbers due to lack of oxygen, cleaning up the algae is a top priority.
As we all know, Asian carp in China is a filter-feeding fish and the nemesis of algae, so the United States began to introduce Asian carp in large quantities. At first, the water quality did have a noticeable effect, and the water quality was getting better and better, but because Asian carp had no natural predators in the area, it gradually became a flood.
Asian carp is not a type of fish, but a collective name for grassy silver carp and carp. With the flooding of Asian carp in the Mississippi River, the U.S. government, fearing that Asian carp would enter the Great Lakes, resorted to various methods to eliminate Asian carp, but to no avail.
These Asian carp are fat, like pigs, and when frightened, they will rush out of the water. Some local governments also organize professional hunters to hunt Asian carp, and the winner has a large cash prize. Even this did not stop the Asian carp from advancing.
At present, the Great Lakes region is in danger, and the presence of Asian carp has been found in the Illinois River, and once Asian carp enters the Great Lakes, the consequences are unimaginable.
Some people say that this is not in China, otherwise how many will be eaten up. It is true that Americans do not like Asian carp with many spines, and there is a fishy smell. Factories for feeding Asian carp have been established in many places, but not large enough to consume the current volume of Asian carp.
It's still a good thing that a small Asian carp can give the U.S. government such a headache. So don't underestimate a small thing, it may make your flesh ache for a lifetime.
