preface
There is such a film "Frankenstein Fish" in American movies, the content is very scary, you can see some not very good memories of the invasive species black fish in the United States.
In the past, Asian carp dominated American rivers, followed by tiger prawns, who flew across the ocean to see the American people.
The American people said that you should not come over, but the tiger shrimp was unmoved, and the white fat eating was thicker than a human arm.
Chinese netizens are hungry and crying when they see the photos of the US invasion of tiger prawns, and they want to cook them into one delicacy after another with exquisite cooking skills.
Tiger prawn invasion
Asian tiger prawn alias black tiger shrimp, the whole body is black brown, and there are yellow stripes, what is more amazing is the size of the black tiger shrimp, 33 cm in length and human arms.
Such a big man, of course, domestic foodies will not miss it, so they put it on the table, and after eating, it is very delicious and fragrant, which is unforgettable.
Soon, as more and more Chinese people want to try it, the price of black tiger shrimp is also rising, and the expensive price of 100 yuan per pound has cooled down the hearts of many foodies.
After all, China is a large land, there are still a lot of high-quality civilian food, which can make people feast, there is no need to pamper this "black tiger shrimp girl".
Nowadays, the Internet is developed, and Americans see through the Internet that Chinese eat such a large black tiger shrimp, and eat so fragrantly, of course, swallowing spit and wanting to try it.
The Americans introduced a batch of Asian tiger prawns back to China, and the Americans were very vigilant this time, and first tied Asian tiger prawns to the Carolina laboratory, first observed for a period of time and then saw if they could be farmed to earn some money.
Asian tiger prawns are leisurely in the laboratory, and the head of the laboratory is also imagining bringing Asian tiger prawns to the American table, expanding not so rich recipes, making some money "by the way", and has begun to imagine the cramps of his banknote counting hands.
But what the head of the laboratory did not expect was that the Atlantic hurricane in 1988 caused floods, God wanted to give this group of Asian tiger prawns in a foreign country freedom, the laboratory farm was destroyed, and the Asian tiger shrimp took the opportunity to sneak away to regain their freedom.
At that time, the Americans also searched, but the sea area is so large, the Asian tiger shrimp entering it is only a drop in the ocean, where can the Americans find out.
The Americans did not find it, but they mistakenly thought that the Asian tiger shrimp was extinct, and if they couldn't see it, they would go back to the business as if they didn't exist, so is the Asian tiger shrimp really dead as the Americans guessed?
Asian tiger shrimp also knows that this temporary lack of strength will have to endure and wait for the day when Americans will be amazed.
Thirty years east of the river, thirty years of the west of the river, Asian tiger shrimp silently grows in the dark, and by the time Americans are surprised to find out how so many there are, the local shrimp are almost dead, and many waters in the United States are full of Asian tiger prawns.
How did the Americans do it, take out the power of science and technology "not talk about martial virtue", and catch the Asian tiger shrimp, because the number is too large, the Americans are afraid of this behemoth, so they will make the Asian tiger shrimp into feed to vent the hatred of the Americans.
It's really sad to kill things like this, but who says Americans won't handle this kind of food?
Of course, there is one reason why Americans will not eat, and another more important reason is that Americans are afraid to eat.
Tiger shrimp are poisonous
A full Asian tiger shrimp is actually very adaptable, no matter what kind of sea, offshore or far sea Asian tiger shrimp is not a word, as well as the salinity and temperature in the sea Asian tiger shrimp are not particularly concerned, a little come to the meaning of refusal.
The diet of the Asian tiger shrimp is also inclusive and omnivorous, with algae, organic detritus and small invertebrates among its favorites.
The fertility of Asian tiger shrimp is the most important, with 800,000 eggs laid in a single row, and it can quickly pull up a family.
Can you eat, live and feed, can Asian tiger shrimp not occupy American waters?
Asian tiger shrimp have become the "big brother" of the sea in the East Coast Gulf and Mexican waters, and they are not here to fight them, and they cannot eat here.
In this way, the aquatic ecosystem in the United States has suffered tremendous damage.
The first is that other small shrimp are not its opponents at all, and the food, including itself, has become a snack for Asian tiger shrimp.
The second is that there are many American mangroves in the East Bay of the United States, and Asian tiger shrimp are particularly fond of it, and the growth of trees has been affected to a certain extent after breeding.
It is of certain significance to know that the United States planted mangroves next to the water, and the roots of mangroves are relatively dense and can effectively maintain soil fertility.
Locals regard it as a protector of water and soil, but the number of Asian tiger shrimp increases, and when they start eating everything, they gnaw at the roots of mangroves, and the role of mangroves is greatly reduced, and they can't even grow.
Finally, the most critical Asian tiger shrimp has a lot of viruses, for Asian tiger shrimp has long adapted to the virus, the virus will not affect the survival of Asian tiger shrimp, but other species and eating Asian tiger shrimp can suffer, or to a considerable extent affect health.
Asian tiger shrimp has grown too large in American waters, and the meat quality has exceeded the optimal body size for eating, Americans still have a certain rejection of this prickly seafood, coupled with the fact of the virus, so the Asian tiger shrimp is killed as feed to feed other animals.
Tiger shrimp farming
Here's how Asian tiger prawns are farmed in captivity, you can see the difference between them and wild ones, and why wild ones carry more viruses.
The first thing to do in Asian tiger shrimp breeding is to establish a pond, which should be established in a place where the water quality is clear and the water source is sufficient, and the soil at the bottom of the pond also has certain requirements for sandy soil, and the area and water depth have certain requirements, so that the Asian tiger shrimp can grow healthy.
The second and most critical is disinfection, after all, it is to the mouth of the thing, if this pass is really difficult to make people rest assured, in the shrimp fry more than 20 days ago, to throw quicklime and bleaching powder into it, some harmful bacteria and parasites are eliminated, from the root of the risk of Asian tiger shrimp infection, block the source of transmission.
After that, plant some aquatic plants in the pond to make it easier for Asian tiger prawns to frolic and rest, and to use them as food on weekdays.
The third is the time of feeding and the specific content of food, two or three times a day, food including but not limited to tofu residue, sake lees, wheat flour made of feed, so that Asian tiger shrimp eat well, at night the tiger prawn leftover feed out to avoid bad effects.
The fourth is to check often, walk along the edge of the pond every day to see the growth of Asian tiger prawns, some necessary equipment can not be saved, such as shade nets and aerators, oxygen content and temperature should be controlled within a certain range.
It is obvious that domestic Asian tiger prawns are much more "delicate" than wild ones and have a lot to pay attention to.
After all, food safety is the first priority, so that Asian tiger shrimp can be exposed to as little virus as possible, and after cooking, they can be safely picked up with chopsticks and sent into the stomach.
Chinese foodies help the United States
Americans actually turned to Chinese foodies to help solve similar problems, and Chinese foodies have become their saviors.
There is an island called cranberries in Maine, USA, and one of the island's specialties is lobster, which far exceeds the consumption of lobsters.
The local leaders, however, were surprised and brought in Chinese to help solve the problem.
There are just over 70 people on the island, but every family depends on lobsters for their livelihood, and around 2012, a record amount of fish was caught, but the price hit rock bottom, and the hard work paid huge losses.
Who can accept this? Local leaders approached our country and brought a sincere trade mission to Hong Kong, hoping to reach a deal with our country to solve their problems.
At that time, our country was also developing relatively well, and in addition, lobster was indeed a rare delicacy, so it was logical to start trade.
In 2015, Maine earned about $20 million because of lobsters, and of course, the orders signed by Maine leaders also had huge concessions.
To reach such a transaction amount on a cheap basis shows that our country's foodie power is huge, helping the small island of the United States solve the problem that has been troubled for a long time.
Compared with lobsters, Asian tiger shrimp is also a similar species, if it does not carry the virus, some Chinese have not been enough to eat in the past.
Of course, in the face of invasive alien species, the necessary vigilance is still necessary, some species want to come to the table is also difficult to eat, in addition, health is a particularly important thing, with the body there is a future containing various possibilities.
epilogue
The invasion of alien species is actually worth taking seriously, after all, once the invasion wants to drive this "outsider" away, the price to pay is very heavy, and in many cases the most important thing is to prevent problems before they happen.
The price of the United States is worth warning, you cannot bring alien creatures back to your country because of a momentary desire, after all, there is no natural enemy, alien species spread wantonly, it is a more terrifying thing.
Of course, Chinese people don't have to panic, this kind of thing still happens relatively rarely, and the chopsticks of the other Chinese are about to move, thinking of a good meal.
Another thing to pay attention to is to protect the green water and green mountains, industrialization must not sacrifice the environment, the food on the table into a health hazard.
