It is understood that the Chinese alligator eel is fierce in nature, and the adult body length can reach 1-2 meters, which is aggressive to people. Even if people can protect themselves well, other fish in the waters will suffer because they will prey on other fish and eat well. The news reported that one or two alligator eels ate up all the fish ponds of fish farmers, and the fish farmers found it was too late, so they had to kill the fish to vent their anger.

Crocodile eel was found in Beijing a few weeks ago, but people still don't know much about it. Now Henan, Yunnan, Hunan, Guangxi, Shandong and Qingdao have all appeared, which fully shows the tenacity of this fish and shows that many people have actually released it secretly.

Speaking of crocodile eels, it is not illegal to sell and raise them, so there is no way to control their flow. When the reporter went to the market for an interview, some merchants said that the fish was still on sale. Since it's still on sale, there must be a customer base.

This kind of big fish must be kept in a big fish pond, which is very difficult to raise. When someone doesn't want to raise it, they will choose to release it. As we all know, an alien species has no natural enemies in the new environment. Nowadays, king crabs are flooding because there are no natural enemies in the Antarctic Sea, and the introduced scavengers are also known for their tenacious vitality. However, these breeders often don't consider the trouble of biological invasion. It is almost useless if oral propaganda tells everyone not to release them at will.

The city where I live once reported a news that a snake was found in the sports square of the community, which frightened the residents. Some people say, isn't the snake far from the city? Why is there a garden in the community? According to Brother Xiao Huo's judgment, this must be his "little pet".

Careful people will find that there are too many similar incidents. I found a strange fish today and a lizard tomorrow. We can't wait until things have happened. These remedies will cost more. I think practical actions should be taken to prevent such incidents from happening.

Although it is not illegal to raise these exotic species, wouldn't it be better to add some measures, such as whether you can leave the buyer's information when buying these exotic species, so that the animal protection association can trace back to the source or keep in touch with the breeder who bought these exotic species, and when he is not raising them, he can put these exotic species under control in time to avoid causing greater losses to the environment?

The above is my humble opinion. I hope that through continuous efforts, the situation of crocodiles and eels can be effectively controlled, and I hope more people will think twice for the environment!
