The so-called invasive species means that alien species enter the local independent biosphere, which destroys the balance between local biospheres. Because there are no natural enemies, the number has increased greatly, which has caused great damage to the local ecological environment. Crayfish, for example, is an invasive species, but because of China's eating goods, crayfish are now eaten by artificial breeding to survive, which is also a failure. In addition to crayfish, bullfrogs, tilapia and oysters have failed to invade.

among the invasive species, oysters are the worst, and crayfish are worse than themselves. Although oysters are rampant in foreign countries, it is the food that foreigners dislike the most. However, because of its delicious meat, high nutritional value and health-care effect, it can also be used as a medicinal material, which is deeply loved by China foodies. It can be seen everywhere in restaurants in China, but what we eat is not wild, but farmed. Because the wild ones are almost eaten in short supply.

Bullfrog is another species that failed to invade. Bullfrog is produced in North China, and foreigners are afraid to eat it because of its ugly appearance. However, with us in, there is no dish that can beat chef China. Chef China has invented various ways to eat it, such as pickled pepper, charcoal roast, hot pot, etc. You can make it into any flavor you like, but bullfrog is really delicious, chewy and particularly delicious. It was originally flooded, and the result was that it had to be eaten by artificial breeding.

Tilapia is also a species that failed to invade. Tilapia has a particularly strong reproductive ability and a short growth cycle, but no matter how fast it grows, it is not as fast as China's mouth. Tilapia is fresh and tender, tastes good, especially when it is made into barbecue, which is especially delicious, and the price is a little expensive. It can be regarded as an invasive species, and it has no dignity to live.
