Every country faces the challenge of species invasion. If an invasive species lacks natural enemies in the area, the species will reproduce frequently, eventually causing the ecological environment of the area to be affected by invasive species. As we all know, there are many varieties of Fish in Asia, and a variety of fish make up the fish culture on the Asian table. Almost every family will stew fish or use fish as an accessory to other foods, not to mention that fish symbolizes more than one year, which is one of the indispensable parts of China's table culture.
In addition to our country's great love of eating fish, Asian countries have different fish cultures. Japanese people like to eat salmon and sashimi, Koreans prefer to eat sauerkraut fish, and people in Southeast Asia prefer to eat large pot stewed fish. All in all, fish has become an indispensable dish on the table of the Asian people.
There is a saying in Asian folklore: Asian carp living in Asia do not live to adulthood. That's because Asian carp doesn't have the best taste before adulthood, the meat is tender, and the fish soup and fish meat made can meet everyone's preferences. Popularize here: "Asian carp" is the American general name for 8 kinds of fish such as blue carp, grass carp, bighead carp, carp, silver carp and so on.
In contrast, with the Asian carp in Europe and the United States, they can live a free life, and even the Asian fish living in the United States have expanded by dozens of times. In fact, the fact that Asian carp live very comfortably in the United States can show that European and American countries lack natural enemies of Asian carp. At the same time, there will be no uncertainties in the basin where Asian carp live, so Asian carp lives very moist in the United States. In our opinion: Asian carp is just a food dish, don't Americans like to eat fish meat? Why do you still raise Asian carp like pigs?
The Asian carp in the Asian market is very poor, and even though the market is full of many artificially farmed Asian carps, the lifespan of these fish is extremely short. Most farmers raise fish until they are about two years old, when the meat is so delicious that they are widely acclaimed in the market. Scientific studies have shown that the Asian carp is large, but the number of Asian carps eaten by humans is too large, so it is difficult for Asian carps to appear in Asia.
In the last century, American industry has developed particularly fast. As a result, the water quality of the Mississippi River Basin has been severely damaged, and the plankton and aquatic plants in the Mississippi River have become the conditions that restrict the growth of freshwater fish in the Mississippi River. Therefore, the United States deliberately introduced grass carp. Grass carp in the Mississippi River have found the most suitable environment for their survival, the Mississippi River does not have natural enemies of grass carp, and aquatic grasses and plankton in the basin provide a food source for grass carp growth. Thus, grass carp can grow to thirty pounds in the Mississippi River.
Grass carp occupy the resources of the Mississippi River, and local freshwater fish have lost their habitat, however, the Mississippi River has no natural enemies of grass carp, Asian carp is flooded in the United States, and Americans do not like to eat grass carp. As a result, the relevant departments in the United States have adopted measures such as power grids and encouraging the development of fisheries. However, these policies did not meet expectations. To this day, residents near the Mississippi River are worried about the rate at which grass carp can reproduce.
Facts have proved that every country must be prepared for species invasion, and there were no crayfish in the market of our country before. Since the introduction of crayfish into China, crayfish have appeared in various rivers, but the demand for crayfish by Chinese residents is particularly large.
As a result, crayfish in rivers have maintained steady growth. Other countries, however, are helpless in the face of species invasions. In general, the Asian carp in China does not live to adulthood because of the environment and the Chinese "foodie". The "Asian carp" that has invaded the world has become fat pigs in European and American countries, but it is difficult to survive in China.
