preface
The Asian blackfish invasion of the United States was rampant, and the Americans were shocked by the fact that the government immediately took measures to eliminate them, and listed Asian blackfish as a harmful invasive species, so they tried to eliminate them.
But contrary to expectations, the superior water conditions of the United States happen to be a paradise for Asian blackfish, and they can only watch the blackfish grow larger and larger and flood in the United States.
Chinese netizens expressed curiosity about this matter, and after understanding, they found that it was actually delicious mullet on our table, so how can the high-quality rare ingredients that are well-deserved in China be treated as dangerous fish in the United States?
American "VIP" - Asian carp
When it comes to the example of species invasion in the United States, Asian carp must be on the list, after all, Asian carp has given them a headache for a long time, but in fact, in the beginning, Asian carp was invited by the Americans.
The reason why I say this is because in the 60s of the last century, algae and other aquatic plants in the United States were flooded, which made the domestic fishery and aquaculture merchants in the United States really bitter.
So they approached the relevant departments in the United States, hoping that the country could solve this problem, and the relevant departments originally planned to use some agents to kill these creatures, but this idea was opposed by the people.
Although it is true that putting chemicals into the river can kill these algae and other aquatic plants, it also greatly pollutes water resources, and it is difficult to guarantee that this will not affect the fish in the lake.
If fish are really affected by these agents, then these diseased fish are eaten by people, which is likely to affect people's health, so the consequences of using agents to kill algae are uncontrollable.
Therefore, the relevant departments invited biological experts to discuss the matter, and after discussion, these experts felt that the best way was to use biological control methods to solve the algae infestation.
After a lot of research, experts found that Asian carp is a good choice, because they found that Asian carp not only feed on aquatic plants such as algae, but also have a strong ability to adapt to the environment, so they firmly believe that these Asian carp will do a good job.
Asian carp, as the name suggests, is in Asia, and at this time, the United States in the Americas does not have this fish, so they can only travel thousands of miles to Asia to ask Asian carp to help.
But at this time, American experts and the Wildlife Service must not have thought that it is the Asian carp that has a strong ability to adapt to the environment, and it will become a great headache for them later...
They were also foolishly thinking they had found the best of both worlds, because they had learned that Asian carp was still a delicacy in China before they introduced it.
Therefore, they are still making their own calculations, thinking that when these Asian carp have completed their tasks well, they can then be turned into a delicacy and served on the table for the people to eat.
However, there is a saying that "the ideal is full, but the reality is very skinny", and from the beginning when they introduced their "guest", Asian carp, things have been going smoothly.
These Asian carp with "American green cards" worked hard in American lakes, nibbling on flooded algae day and night, and soon completed the task brilliantly, which made American fishermen and the government happy.
But because Asia is extremely adaptable to the environment, coupled with their strong reproductive ability, with the completion of the task, the algae in the lake disappeared, and all of them became Asian carp.
Then, with the seasonal rising water, Asian carp began their "adventure" with the river, and then with their excellent ability, they appeared in major lakes and rivers in the United States.
This can make the Americans sad again, just solved the algae flood, and as a result, the Asian carp flood, after which they learned this lesson, no longer dare to easily introduce species.
So if this is the case, how did the Asian blackfish run to the United States, and how did it replace the Asian carp and dominate the American rivers and lakes?
The "king of rivers" in the United States - Asian blackfish
To know that Asian carp is enough to give Americans a headache, but there is no worst can only be worse, the emergence of Asian blackfish, so that Americans really know that Asian carp in front of it, but it is really a small witch.
As soon as the Asian blackfish appeared, the Asian carp king in the American rivers has been declared over, the Asian blackfish is not only more than one meter fat like a pig, several times the Asian carp, the appearance and temper are also extremely fierce.
And the environmental adaptability of Asian blackfish is also very "fierce", compared to Asian carp, that is more than enough!
Asian blackfish has basically no requirements for water quality and environment, simply put, there is water, and it can swim around without pressure in minus 40 degrees Celsius, if it is too cold it will begin to hibernate.
However, the water temperature in the United States is simply a piece of cake for Asian blackfish, and it is not needed to hibernate and save life, because the water temperature is generally between 10~30 degrees, so Asian blackfish is also very comfortable for this, and it is not an exaggeration to say that it is paradise.
In addition to the superior living environment, Asian carp, as a raw carnivorous fish, is not a joke in the position of the food chain, and basically has no natural enemies.
Let's talk about the survival ability of these black fish, it can be said that without human intervention, it can be said that it is difficult for them to die.
This is because in our perception, once a fish leaves the water, it is equivalent to entering the countdown to death, but the Asian blackfish is beyond our understanding, it can leave the water thanks to its gills.
The gills of Asian blackfish are different from ordinary fish, so they can absorb oxygen like us humans when they leave the water, as long as they can hide in the mud and survive for a while without water.
So in this way, is it not surprising that the Asian blackfish has become the "king of rivers" in the United States, but why did the blackfish in the Asian river basin appear in the United States, it can't be swam by itself?
The United States surprised the Asian blackfish
In fact, when Asian blackfish first appeared in the United States, everyone thought that the country introduced new species in order to sanction Asian carp, until they found that Asian blackfish gave them more headaches than Asian carp, only to find that this was not the case.
So they began to look for why Asian blackfish appeared in the United States, and found that in fact, Asian carp did not swim over by themselves, nor were they deliberately "smuggled" by intentional people, they actually entered the United States in a legal capacity.
It turned out to be a fish farming enthusiast, and in 2000, he found Asian black fish abroad, because Asian black fish was still ugly and cute when they were young.
So the fish farmer got a few to bring back to the United States, and what he didn't expect was that the fish grew so fast that it didn't take long for the tank to fit down.
In addition, the Asian black fish that grows up is not good-looking, not only is it large and fat like a pig, but the fish spots on the body are as ugly and seeping as snakes.
At this time, he did not want to keep these Asian black fish at home, but he also developed feelings for these Asian black fish, and he could not kill them, so he released them into the river near his home.
But I didn't expect that it was such a decision that led to the crazy expansion of these Asian blackfish in the water, and finally became the king of rivers in the United States.
But at this time it is too late to say anything, the rivers in the United States have been occupied by Asian blackfish, and finally this matter reached the ears of Chinese netizens.
Chinese netizens also wanted to see what species it was, and actually made the Americans at a loss, and the result turned out to be our Sichuan cuisine "sauerkraut fish", which often uses the ingredients of mullet.
This can't help but make our Chinese netizens feel crying and laughing, bluntly saying that it is really a drought death, waterlogging death, you know, because mullet is delicious and highly nutritious, it is an excellent ingredient in our China, and the price is not cheap.
Therefore, Chinese netizens also said that the Americans are really destroying the heavenly things, and really do not understand how the United States can be helpless with Asian black fish, and directly turn it into a delicacy?
Although we have all thought of the method to the Americans, the Americans say that they have more than enough energy, because they have always been very bad at the cooking method of fish.
In addition, when they eat fish, it is different from us directly in the mouth to pluck out the thorns, they are used to removing the thorns of the fish before eating, because it is too cumbersome, so they say that eating crabs and lobsters is more enjoyable.
It is precisely because of this that Asian blackfish are not even interested in them when they are the biggest natural enemies in the United States, which makes them even more brazen in the United States.
Although the arrogance of Asian carp and Asian blackfish in the United States is indeed a matter of making us cry and laugh, we must also take the United States as a lesson and be vigilant against the invasion of alien organisms.
For example, the scavengers and water hyacinths that appeared in our country in the early years are invasive of alien species, but fortunately they are not as serious as the United States, but even this still has a great impact on the ecology of the mainland, and then it is difficult to extinguish and completely solve the problem.
epilogue
We must know that biological invasion is actually a very terrifying thing, so our country is also very, very strict about the import and export of biological things.
Even then, it will be difficult for us to completely avoid biological invasions, so if you find any alien species that you have not seen, you must report it in time.
Because only then will it be possible to extinguish it before it has a huge impact!
