The terrible thing about biological invasion is that it will seriously damage the local species diversity and cause economic losses in agriculture, forestry, fisheries and many other fields. These alien species often lack natural predators and reproduce extremely quickly, leaving the local people miserable. When these arrogant invasive species came to China, the situation seemed to have changed dramatically.
This issue of the science and technology concept will take everyone to take stock of the eight invasive species that have been eaten "scarce".
1. Crayfish, everyone is familiar with it, in the summer roadside stalls, crayfish and beer have become a classic fixture. At first, the crayfish in the United States were very arrogant, relying on their super reproductive ability and adaptability to go around.
After coming to China as feed for bullfrogs, they still did not change their bad temper, causing serious damage to the ecology of the mainland. But how could a strong Chinese in his life ignore such a bully as him, and bring him to the table with three or two clicks.
2. African bullfrog, people generally referred to as bullfrog, native to North America, the mainland was introduced from Cuba in 1959, just introduced bullfrog soon China flooded, to the evening is "listen to the sound of frogs a piece", the noisy Sleepy Chinese foodies are not idle, they found that bullfrog meat is tender, delicious taste, and bullfrog is not only rich in nutrients, its skin also has a certain medicinal value.
Within a few years, bullfrogs went from rampant to in short supply, and people immediately began to breed bullfrogs artificially. At present, bullfrogs are already one of the important aquatic products of mainland aquaculture, which has a great role in promoting the economic development of aquaculture.
3. Crabs, crabs are also one of the notorious invasive species, Brazil is harassed by them every year, these guys climb all over the road in groups, let the Brazilian cars strike at every turn. But these crabs do not dare to "walk sideways" after coming to China, a small rope is tied, either braised or steamed, chinese foodies are still very enthusiastic about crabs.
4. Oysters, did not expect it, oysters are also exotic species, originated in Denmark, Danes feel that oysters are ugly, do not dare to mouth, so they can only let this guy bully. But Chinese foodies are not so exquisite, these wading oysters are neatly arranged on the barbecue grill, and now the oysters have long become the top of the barbecue industry, known as men's gas stations, women's beauty salons.
5. White jade snails, their hometown in Africa, the largest can grow to twenty centimeters, in the snail family is also a "big Mac", mainly feed on fruit trees and crops, is a world-wide reputation is very poor.
After the white jade snail came to China, it was soon discovered that its delicious side, and they were rich in amino acids and high protein to achieve low fat content, so that it quickly became the perfect food in the eyes of foodies.
6. Starfish, starfish is not as honest as The Star of SpongeBob SquarePants, it is said that starfish will torture it for up to eight hours in order to eat clams, which also makes starfish sit on the title of "undersea locust". In 2021, starfish flooded Qingdao, leaving local fishermen with two big heads, but fortunately, everyone quickly thought of a solution.
In line with the consistent logic of solving the problem and solving the problem, the starfish soon fell into the hands of Chinese chefs, and after the chefs' work, the starfish became extremely delicious, and even the foodies ate the price increase, and the chefs could only be blamed for the delicious food.
7. Asian carp, at first the United States in order to solve the problem of algae flooding in the Great Lakes, chose to introduce Asian carp, Asian carp did solve the problem of algae after the introduction of Asian carp, but Asian carp began to flood again, making Americans overwhelmed.
In the end, the United States, which really had no way, decided to sell these big carp to China, solve the problem and get an income at the same time.
8. Tilapia, the origin is also in Africa, the viability is extremely strong, in the harsh environment of Africa can be at ease, to change to other good conditions of life is even more mixed. What it did not expect was that after coming to China, its most frequent place turned out to be a wet market.
Tilapia has a delicious meat and excellent taste, steamed and braised can make a rare delicacy, and is praised by many diners as "white meat salmon". In the end, the vigorous tilapia not only did not flood, but also had to rely on artificial breeding to supply. Although these invasive species have been eaten to the point of captivity, not every invasive species can be perfectly resolved.
The mainland is still strengthening its protection against alien species. If an individual introduces an alien species from abroad, it will be punished by the relevant departments, and the person handling the case will bear a fine of 50,000 yuan to 250,000 yuan, so everyone should pay more attention.
