In China, there is a saying that "carp jumps the dragon gate", but the Asian carp in the United States is going to jump over another thing, do you know what it is? The answer is that the U.S. government spends a lot of money to place a "power grid" in the river channel, and the Asian carp that can "jump the grid" once became a nightmare for Americans.
"Carp Leaping Dragon Gate"
Today's talk is another invasive species that is more "fierce" than the Asian carp, which is the blackfish, and was even once called "mutated monster fish" by locals. So, what exactly is the blackfish that invaded the United States? Why has it become a nightmare for Americans? How did the Americans deal with it? What is the status of this terrifying blackfish on the mainland?
American blackfish invasion
If the Asian carp has given the United States enough headaches, then the blackfish today is even more terrifying, it has grown to a meter long in the United States, and it looks like a huge "water snake" in the distance. Why do the blackfish here look so "fat and strong"? Why don't Americans grab such a fine ingredient to cook? It turns out that the American people need a Chinese stomach.
"Terror" blackfish invaded the United States
When it comes to the flooding of blackfish, many "blackfish meat lovers" must not be able to sit still, how do you feel that any delicious ingredients can be flooded abroad? In fact, the blackfish is indeed "running amok" in the waters of the United States with its own tough physique and temperament. So, first of all, let's talk about what kind of "fish" blackfish is.
A few big blackfish
Blackfish are freshwater benthic fish that prefer to live in aquatic grass or silt-heavy waters, and like the Asian carp, the excellent quality of the blackfish is "strong", as long as the pollution of the waters is not too serious, it can live in place. The scientific name of the blackfish is actually called "snakehead", I believe that many places still call it this way, so it is called mainly because of its shape.

The overall color of this type of fish is gray-black, and only the abdomen is light white. And its head is relatively flat, far from the head shape looks somewhat similar to the "triangle", because of this, the United States will also call the blackfish snakehead fish. Imagine a fish with a head like a snake's head and a body length of up to 1 meter "charging" at you, and presumably people who are not familiar with this type of fish will subconsciously choose to escape.

Don't think that "fast charge" is an exaggerated description of blackfish, in fact this fish is really very fierce. We can see from the description of blackfish in the US media that they believe that this fish's mouth is full of "sharp teeth" and jumps very high, and it can be described as merciless when it "mouths" other fish.
Asian carp army
In this way, the United States classified "snakehead fish", that is, blackfish, as harmful invasive species in the United States under the 1981 Amendment Act of the Lacey Act. If there is still a little "gratitude" for the Asian carp, after all, the Asian carp made a great contribution to cleaning up the river water and grass, then the Americans should not have the slightest good feeling for the blackfish, which is a terrible-looking fish.
Structure of the fish
But no matter what kind of "criminal" the United States has characterized itself, Blackfish still flaunts its might in the waters of the United States. Not only will the living space of local fish be squeezed wildly, but also from time to time to come out to scare the American people who have never seen the "world", which makes everyone very distressed.
"Fat Blackfish"
Therefore, in order to solve the situation of blackfish invasion and flooding, the United States began to "return to the old business" and wanted to "cure fish scientifically." Needless to say, this method has been used in Asian carp in the past, and the effect is very general. However, the United States obviously does not believe in evil and feels that it can still use technology to defeat the "blackfish". So they not only put chemicals such as fish vine ketones and herbicides in the waters where blackfish are everywhere, but also built a power grid to prepare to catch the blackfish who are also good at jumping.

The ending is also not optimistic, although the population of blackfish has decreased a lot under this blow, but "wildfires cannot be exhausted, and the spring wind blows and grows again", and it did not take long for blackfish to recover their vitality. Seeing this, many Chinese foodies "hate iron not steel" and do not understand why Americans do not salvage blackfish to make spicy fish, sauerkraut fish, boiled fish, air-dried fish, grilled fish...
Delicious sauerkraut fish
So why don't the Americans eat blackfish? Is it really just because of the lack of a Chinese stomach?
The reason why the American people refuse to eat blackfish
First of all, in terms of the dietary preferences of Americans and Chinese, it is indeed normal that they do not like blackfish. After all, compared with the domestic "steaming, frying, frying and stewing", the American cooking method is indeed relatively simple, so the delicious blackfish in their hands can not become a delicious dish.
A variety of cooking methods
In addition, freshwater fish have more fish bones, which must be known to everyone. Therefore, eating fish in China is a "technical work", you must be very careful to pick the fish bones, otherwise you will accidentally "stuck" the fish bones in the throat eyes, which may be a lifetime of shadows. Therefore, Americans prefer to eat marine fish with fewer spines, and it is normal not to be interested in this kind of fish that requires careful cooking and patience to pick thorns.
Marine fish species
Secondly, the blackfish in the United States and the blackfish in China are not exactly the same, although if you "ask the ancestors", they are indeed the same kind of fish. But after growing in different water quality environments for so many years, they have long been different from each other, which is indeed "one side of the water and soil to raise the other side of the fish".
"One side raises fish in the soil and water"
Blackfish in the United States are very large, and there are not a few people who grow up to 1 meter long like this. However, it is not that "the bigger the better", these huge blackfish tend to be very thick flesh. Not tender at all. And because most of the rivers in the United States in the last century were heavily polluted by heavy industry, the blackfish living in them faced the same embarrassing thing as the Asian carp, that is, the "heavy metals in the body" exceeded the standard.
Blackfish are also known as snakehead fish
Therefore, for the sake of their own "life safety", even if they have the Chinese stomach, they should not have the slightest desire to eat these blackfish. To give a simple example, even if you really like to eat turtles and think it is very good to stew and braised in soup, if you travel to India and fish a Ganges turtle from the Ganges to make you a dish, would you be willing to eat it?
Flood of blackfish
I believe that most people are rejecting, after all, what the water quality of the Ganges River is, everyone knows it, "appetite" and "life safety" in comparison, life safety still has the upper hand. In summary, the reason why the American people do not eat the flood of blackfish, in addition to the lack of "Chinese stomach", also need Chinese cooking technology, cooking spices, and most importantly, the "blackfish" that needs to grow up in clean water.
Chinese cooking: stir-fried
Of course, the blackfish in the rivers of the United States did not expect that they would become a species with "no natural enemies" here. You must know that in China, the people are still very fond of blackfish, not to mention the exaggeration of eating it to extinction, anyway, it is impossible to let it flood in China's waters.
It is no wonder that when everyone hears the flood of Australian crayfish and the flood of hairy crabs on the Banks of the River Thames in the United Kingdom, they will be very "resentful", and these foreigners are indeed too reluctant to "eat"!
Crayfish flooding
Chinese have long discovered the value of blackfish
We often say that "China on the tip of the tongue" is by no means an exaggeration, which can be traced back many years. In the case of blackfish, the people of the mainland have a very long history of eating blackfish, because this fish appeared in the Shennong Materia Medica as early as 2,000 years ago and was listed as "superior".
The Shennong Materia Medica describes the blackfish as follows: "The taste is sweet and cold, the main wet paralysis, the face is puffy, and the water vapor is sewage." ”
Blackfish fillets
This is actually very normal, because China has had a tradition of "food supplements" since ancient times, and many of us now believe in "what to eat and what to supplement". The blackfish is listed as the top product, which means that its own edible value is very high, of course, in addition to its own rich nutrition, the taste of the blackfish is also very delicious and silky, it is no wonder that so many people like to eat it. What kind of "dry kun" is there in the body of the blackfish?
Four large freshwater fish
In terms of composition, the crude protein contained in the meat of the blackfish is higher than 17.63%, which is an advantage compared with the four major freshwater fish on the mainland. In addition to crude protein, there are many amino acids in the fish meat of blackfish, of which 7 are essential amino acids.
Data show that each 100g of blackfish meat contains 19.8g of protein, 1.4g of fat, and 384.6kJ of calories. Calcium 57 mg, phosphorus 163 mg, iron 0.5 mg, thiamine 0.03 mg. The tail muscle contains 18 kinds of free amino acids such as citrulline, proline, and silk helium acid, etc., and it is good to eat and drink medicine.
Sour soup blackfish
Of course, Chinese there are many ways to cook blackfish. For example, take the soup or directly "steam", in short, the conditions of the blackfish itself are already very superior. So it only takes a little processing to become a delicious dish.
Blackfish found in the United States
This is probably the pain of "the honey of the other, the arsenic of the Ru", which is a popular ingredient in China, but in the United States, it has become a representative of "terror".
