When Japan released the news that it was forbidden to sell crayfish and released them, many China foodies felt very sorry and accused the Japanese of not knowing how to eat. They all belong to crayfish, and the difference between China and Japan can be said to be a world of difference. The Japanese people hate crayfish very much, because crayfish is an invasive species there, which has damaged Japanese farmland and made the local people miserable. However, because China's food culture is profound, I didn't expect crayfish, as an invasive species, to come to China, but instead, it became farmed, which was simply not enough to eat.

The crayfish we often see in the market are actually native to the United States, and later introduced by various countries in the world, and have been farmed in Japan and China. However, the difference between Japan and China is that Japanese people don't like crayfish very much, which is also related to the local food culture. Japanese people pay great attention to their own culture and think that their country's products are always the best quality, so they pursue domestic things when shopping.

Because some Japanese people are brainwashed by those marketers, all aspects of life, including the treatment of food, are blindly pursuing domestic production, so they don't like exotic species like crayfish. Japan introduced crayfish from the 1920s, when it was used as feed for bullfrogs. I didn't expect crayfish to have a strong vitality. After arriving in Japan, not only did it not become acclimatized, but it became better and better. Even some crayfish escaped and established their own population outside.

Crayfish have very strong reproductive ability. On average, a crayfish can conceive about 300 eggs, and these eggs will stay in the abdomen of crayfish for several months, so the survival rate is very high. When the population of crayfish gradually grew, there was a destructive scene. Because crayfish are omnivorous animals, I usually eat plant algae and insects, so I often grab food with local fish and shrimp. Moreover, crayfish are very good at digging holes to escape. When they are in the wild, they often destroy the ridges and even dig holes on the dams, which directly affects the safety of the lake. Therefore, the Japanese side felt that crayfish were not necessary to be protected, so it was forbidden to sell crayfish, which was also a means to fight against alien species.
