Japan has passed the latest version of the Alien Biology Law, which specifically mentions Mississippi crayfish and prohibits their sale and release. Of course, there are no special restrictions on keeping individuals as pets.

although it is called? Crawfish? , but it has little to do with lobster. The real name crayfish, as far as the biological classification of subspecies exists, is a member of the decapod-crayfish-crayfish genus. Lobster generally refers to 46 species of animals belonging to 11 genera under the family Decapoda. It can be clearly seen that crayfish and lobster are far related and belong to two families. Crayfish has now become a delicacy on the table. Of course, eating crayfish is mainly in the night market, and it has also become a dietary trend. The reason why the sale of crayfish is banned in Japan is that after being brought to Japan from the United States about 1 years ago, crayfish proliferated in ponds and other fresh water areas all over Japan, resulting in a sharp decline in native species, which led to discussions on designating them as alien invasive species.

In fact, the reproduction ability of crayfish is still relatively strong. She can lay eggs in two months and then lay 3 eggs every 2 days. Therefore, once crayfish begin to flood, local life will be seriously affected and the ecosystem of the whole area will be destroyed. In this way, it is understandable that the Japanese prohibit the sale of crayfish, because they don't eat or cook crayfish themselves. In the past, there were a lot of crayfish in China, and their reproduction speed was also very fast, but after they became delicious food, they were consumed very quickly. As an alien invasive species, it has all the characteristics of alien invasive species. It has a strong ability to survive and adapt, and it can survive without high waters, destroying the local ecosystem, which is one of the reasons why some people criticize crayfish.

Secondly, there are many kinds of crayfish recipes. They eat small fish and shrimp, and also eat some animal carcasses. In short, living in a new environment is pleasant without any trouble. The third point is that it has a strong reproductive ability at maturity. It takes only 9 months for crayfish to mature and enter the breeding period. Each female crayfish can lay hundreds of eggs in each breeding season.

As the crayfish season approaches, you must remember to pay attention to a healthy diet. This is a place where freshwater species need special vigilance. Eat it after cooking to avoid being hurt by parasites. In addition, the taste of crayfish lies in the strong smell of oil. It's not as tasteless as sea shrimp when cooked. Strong taste is delicious, but it is harmful to health. People should pay attention to eating in moderation when eating.

if you especially like eating crayfish, especially if you make it yourself, try to wash and soak it as well as make it well. Try to eat as little crayfish as possible that can't guarantee the source or freshness on the street.
