The Asian carp, also known as the "Asian carp", is a very widely distributed fish, but in the United States, the Asian carp is said to be a lot, because they refer to the related species of blue carp, grass carp, bighead carp, silver carp, crucian carp and carp as "Asian carp", and this fish has been flooded in the United States, and the Americans want to eliminate this fish.
And we want to add value, because our demand is too large, occasionally out of stock can not eat, here is worth explaining that in fact, the United States said that most of the more species of "Asian carp" are the silver carp and silver carp.
When it comes to silver carp and silver carp, everyone understands why Americans are reluctant to eat "carp", "fishy smell and thorny" is the main feature of this fish, so it is completely normal, let's take a look at the situation of this fish.
<h1 class="pgc-h-arrow-right" > Why did Asian carp flood in the United States? </h1>
The Asian carp is known as the "most dangerous exotic fish species" in the United States, and the reason why this fish came to the United States is because in the 1960s, the United States urgently needed a safer and more effective way to reduce the growth of local aquatic plants such as algae.
So at this time, the U.S. Fish and Wildlife Service "had a flash of inspiration" and thought of biological methods to control it, so that not only is there no pollution, but it may also bring certain economic value. After that, the United States formulated the "Fish Introduction Plan".
Isn't that? Asian carp "took a special plane" to the United States, and finally contributed to the ecological environment of the United States, because Asian carp is very fond of eating microorganisms and phytoplankton. In the beginning, Asian carp honestly stayed in the fish pond.
But we know that the ecological environment in the United States is also a relatively extreme model, under the model of global warming, the extreme climate phenomenon is more and more, and finally the United States has a heavy rainfall - rain surge, at this time, the opportunity for Asian carp comes, and the food in small ponds is completely insufficient.
So when the Water rose in the United States, they fled these fish ponds, and along the Mississippi River all the way north, the habitat could not be expanded, at the beginning, there were many fish farms have followed suit, the introduction of "Asian carp" as a natural pond cleaner, the range of its own habitat is very large, the result of heavy rain, and eventually the habitat expanded even larger, so it was out of control.
By the 1980s, Asian carp had been found in rivers and lakes in more than a dozen states in the United States, so it had a devastating impact on the ecology, which was the reason why Asian carp flooded in the United States, initially liked, and later hated.
< h1 class = "pgc-h-arrow-right" > huge amount of money, and the poison cannot deal with the Asian carp</h1>
Seeing this flooding, the large-scale Asian carp has no way to control it, and eating can not solve the problem, and the United States must take an economic approach to control it, allocating more than $18 billion to intercept Asian carp after the 1980s.
In 2012, it was even more expensive to continue to spend $51.5 million to prevent the Great Lakes of the United States from being invaded by Asian carp, and as a result, the invasion of Asian carp was still difficult to control, and finally the United States came to China to ask for a way to control it, and there was no news for the time being.
And above we also said that the United States also uses high poison to control Asian carp, it is indeed true, the United States poisoned in the waters where carp is dense, but the result is that Asian carp is not poisonous, but the Native Fish in the United States is poisoned a lot, so this measure has failed again, and then the United States tried to set up a defensive fish grid in the water, but they did not expect the carp to jump.
At the same time, some bows and arrows were used to catch Asian carp, but the interesting thing is that the carp that jumped out of the water is aggressive, and a female archer was once "slapped" hard, which is really true.
So the Asian carp is like a mutation in the United States, completely out of control. Of course, one of the main reasons we also know is that the introduction of Asian carp, the United States may not have thought of at first, the species has no natural enemies, so the final flood of the species, there is an uncontrollable situation, there is no natural enemy to grow at will, and Americans do not like to eat, that is not to mention the economic value, but may lead to huge costs leading to economic regression.
< h1 class="pgc-h-arrow-right" > Asian carp breed so strongly? </h1>
Indeed, judging from the degree of flooding, it can also be known that the adaptability of Asian carp is very strong in the United States, and according to the report, they also eat a large amount of food, eating food equivalent to about half of their own weight every day, and can easily grow to more than a meter long, weigh 100 pounds, and no one eats.
In addition, each female Asian carp can lay 3 million eggs, which is completely overloaded, so the entry of such creatures into the United States is entirely leading to serious damage to the ecosystem in the region.
There is such a data shows that in Hanoi, Illinois, there are tens of thousands of large and small Asian carp living on average every mile, and it is estimated that Americans have no appetite at all, people are no longer their opponents, and the United States can only ask the American people to "catch Asian carp" to alleviate the ecology.
This is the consequence of the introduction of Asian carp in the United States, of course, Asian carp is not a protected species in the United States, it is a species that hopes to be completely eliminated soon, this is the general situation.
So in general, there are so many Asian carp, eating is definitely not OK, many people have a big brain, may say that China is not enough to eat, but also "value-added", why not transport back to China? It did happen.
In 2011, the Chinese market appeared in the United States imported Asian carp, but because Chinese prefer fresh fish, imported Asian carp is frozen, and the price is expensive, so the sales have not been good, then it can not be sold, no one buys, so the Asian carp in the United States is not eaten.
