The Americans have no way to escape? Black tiger prawns, larger than the arms of adult men in fitness, have completely surrounded them!
In 2015, a fisherman accidentally caught a very strong shrimp during fishing, which was larger than an adult man's arm, and the US government was pleasantly surprised to learn about it and immediately ordered vigorous farming, but what they did not expect was that these tiger shrimp became their fatal enemies.
So, what is the arrogant Asian tiger prawn, and why is it flooding in the United States?
♦♦ "Black tiger shrimp in the United States" ♦♦
Some time ago, the editor just saw on the Internet that the "Big Mac" rats that were raging in British towns and cities with a length of half a meter were long, but I didn't expect that there were shrimp larger than an adult man's arm.
Some time ago, a fisherman caught a large shrimp up to 30 cm long while fishing, and the fisherman was shocked to see this behemoth, although he has been fishing in this watershed for so many years and has seen such a large lobster, but he has never seen this big shrimp that does not know what kind of shrimp.
He immediately put this strong shrimp on the deck to compare his arm with it, and actually found that the size between the two was comparable, which was simply a rare thing, and immediately took out his mobile phone to take a group photo, after all, this fisherman usually has the habit of fitness, and his arms are thicker than ordinary people.
After filming, I looked at this prawn but was worried: how to deal with this shrimp, will it be highly toxic in its body if it looks so different? After thinking about it, he decided to take him to the Trot River Fishing Company.
The first reaction of the staff of the Trot River Fishing Company when they received this shrimp was that this shrimp had mutated, it must be a new species, and they could not be careless, and they had to quickly find relevant experts to come and test it.
Experts rushed to find that it was an ordinary Asian tiger prawn.
Asian tiger shrimp, its appearance is relatively outstanding, because its whole body color is darker, mostly black or dark gray, the back and tail part of the interlaced black and orange stripes, and tiger body is very similar, so it is also commonly known as black tiger shrimp.
After the confirmation of experts, finally know what this thing is, although there is no harm, but its size is really scary, never seen before, the Americans thought for a few days and nights or decided to ask experts to study and analyze the composition of this shrimp in detail.
This analysis simply made all Americans applaud, because this shrimp is rich in astaxanthin, although most shrimp and crab contain astaxanthin, but it is a full 20% higher than other ordinary shrimp.
As soon as they knew that it had such a high value, everyone knew that Americans were close to money, and the government departments were simply like seeing money, and they went up to grab it, and immediately forced the breeding companies in the coastal areas to carry out large-scale aquaculture.
Originally, everything was calculated, and major companies began to invest in farming, but people were not as good as heavenly calculations, and a sudden Atlantic hurricane in 1988 shattered the American dream.
♦♦ "Why is black tiger shrimp flooding in the United States" ♦♦
According to the recollections of the parties, the scene of the disaster at that time was very terrifying, some people were sleeping soundly at home, some people were leisurely enjoying life in cafes, and some people were leisurely walking with their other half on the street, but in an instant everyone had not figured out what happened, and even people with rooms were swept into the huge waves.
In an instant, hundreds of thousands of people on the South Coast of the United States became homeless, and if you think about it, the shrimp that spend a lot of money on farming have little place to stay.
The next Americans are simply busy, the government seized the time to start arranging financial resources and manpower to start disaster relief, busy rebuilding their homes, and there is no time to care about the tens of thousands of black tiger shrimp that have invested a lot of money on the beach.
When everything was almost busy, they almost forgot about the fact that they had raised shrimp, and then something happened that they could not have dreamed of.
Because don't look at the many creatures in the American waters, but so many creatures can not restrain the existence of black tiger shrimp, so that the invasion of black tiger shrimp is more smooth, they seem to be happy, wantonly destroying the biological chain of the United States.
Later, when some fishermen went out fishing, they found that a net went down, and it was basically all this strange shrimp, which was too different from the previous harvest.
And those of them who depend on fishing for a living, it is very difficult to go out to sea once, if they can't catch some valuable fish to bring back, then where can the rice at home be boiled, so the fishermen immediately took out their mobile phones to take pictures, wanting to take them to experts to see if they could find an answer.
Who knew that as soon as the relevant experts saw these photos, they finally remembered the tiger prawns that they had forgotten before, but at this time, they found that it was too late, because it must be particularly troublesome to deal with it at this time.
Because these monster shrimp took advantage of the favorable opportunity to develop wantonly, not only silently occupying the Gulf of Mexico and the eastern coastal area under the noses of the Americans, but then they did not seem to be satisfied, and directly spread to the surrounding areas at an unimaginable speed.
Because they are usually very good to feed, as long as there are other shrimp and some plankton in the river, they can survive, because of this, this does not leave room for other shrimp, as long as there are tiger prawns in the river, then other their living space will be encroached upon, and over time, they will face extinction.
What makes Americans more troubled is that the black tiger shrimp reproduces very fast, it has two spawning periods every year, and can produce about 50-1 million egg babies at a time, and these eggs are also very easy to feed, as long as the water temperature is between 13 degrees and 32 degrees, tiger shrimp can grow.
And the water temperature of the rivers on the east coast of the United States happens to be in the middle, so this is simply the right time and place for the tiger prawns, so they turn the entire area into their territory in a short time.
♦♦ "Count the dangers of black tiger shrimp" ♦♦
Then some people say, shrimp has always been a delicacy on the human table, how many people drool after seeing it, why don't the Americans salvage it up and eat it after processing, but let them dominate the same as the king of the mountain in their own rivers, what is the harm they have?
Because black tiger shrimp are typical carnivorous marine life, they are different from other shrimp, which are generally called "river cleaners" and eat many rotten creatures in the river every day to maintain the ecological hygiene of the river.
But the arrival of tiger shrimp is undoubtedly their disaster, gradually tiger shrimp after other shrimp are killed, no organisms continue to maintain river hygiene, the water quality of American rivers began to slowly decline, which is more unsuitable for the growth of other organisms.
What's more, tiger shrimp and other organisms live together for a long time, and the bacteria it carries will infect other organisms.
This series of phenomena means that action must be taken immediately, otherwise these black tiger shrimp have not grown in moderation, and the consequences will be unimaginable if they grow larger and larger.
Controlling the reproduction and spread of black tiger shrimp is imminent for the United States, and the first way they think of is to eliminate it with drugs, after all, this trick is the fastest, so the government began to buy a large number of chemical drugs to sprinkle into the river.
This method is very familiar, just like extinguishing fires, where there is a fire, it is extinguished with water, but this method is simply a palliative but not a cure, because these drugs temporarily contain the flooding of black tiger prawns, but the water quality of the same river water is also destroyed, and other organisms have no chance to survive.
What's more, the river here is surrounded by mangroves, and the destruction of river water quality has directly reduced the number of mangroves and is on the verge of extinction.
The vitality of black tiger shrimp is extremely strong, may not be able to accept the baptism of medicine at first, the number is reduced, but slowly they seem to adapt to this environment, begin to integrate with this drug, and become "poisonous shrimp".
Such a creature full of toxic substances, Americans are afraid that it is too late, let alone eat, and since the inland rivers of the United States have been seriously polluted, although the relevant departments have been in the treatment over the years, but it has no big effect, and most Americans such as locally grown fish and shrimp do not consider it at all.
♦♦ "Whether such an incident will happen on the mainland?" ♦♦
Since the flooding of tiger shrimp has such unimaginable harm to the ecology and the environment, I believe many people will wonder whether the mainland will also be affected?
For now, the mainland is not suffering from the same troubles, but these things that are very terrible in the eyes of Americans have become a delicacy on the table of ordinary people at home.
On the one hand, it is mainly because the mainland has a particularly rigorous attitude and policy to prevent biological invasion, so there is a very scientific and reasonable plan for this relatively special creature, so the chance of flooding is minimal.
On the other hand, the mainland has always attached great importance to the construction of the ecological environment, and at the same time severely cracked down on the destruction of green waters and green mountains while the society continues to develop, so under our careful protection, the river sanitation meets the standards.
Therefore, black tiger shrimp carries very little virus in such an environment, and has reached the standard of eating, so it can become a delicacy in everyone's mouth.
In contrast, the rivers of the United States have been polluted by heavy metals for many years, and after the black tiger shrimp goes there, it absorbs harmful substances every moment, how can the body not accumulate various germs?
The most important thing is that the farms on the mainland are strictly in accordance with the national standards, are very formal, and the composition of the water is also strictly tested, which has largely ensured the safety of tiger prawns, under the blessing of five thousand years of gourmet cooking technology on the mainland, these tiger prawns usually become delicious, and there is no opportunity to go crazy.
Therefore, although tiger shrimp is an alien species, the mainland can treat it with a very correct concept, first strictly control the quality of aquaculture water, and then send them to the table in the right amount at the right time, so at present, there is really no need to worry about the crazy growth of tiger prawns, uncontrolled and other problems.
However, even so, if you buy shrimp like this, you can't release them arbitrarily, because after all, their reproductive ability is very strong, and in case of rapid reproduction, it will bring certain threats to the ecology of local waters.
Therefore, in order to solve the problems caused by the invasion of alien species, we must not be careless, nor can we use some extreme methods, we should learn to take a long-term view, enhance our ability to predict and solve the problem from the root!
