With the development of trade and personnel exchange, a large number of exotic creatures have entered China, and the arrival of these species will also have a very bad impact on the development of local agriculture, animal husbandry, ecological environment and fishery. This Chinese alligator eel in Henan is an exotic species, which is very aggressive and will eat a lot of fish and shrimp in the river, causing great damage to the ecology in the water and the cultivation of aquatic products. Therefore, in order to catch the sweeper ashore, the local area even drained the river. However, due to the complex underwater environment, the progress of subsidies for crocodiles and eels is relatively slow.
In addition, the reproductive ability and destructiveness of exotic creatures such as crayfish and scavengers are also very strong. But crayfish tastes very good when made into food, so this exotic creature has become a delicacy on the table in China. The street sweepers are just not delicious and troublesome to handle, so our country has been severely hit by street sweepers. Therefore, from this perspective, if alien species can be transformed into an economic benefit, then you can choose not to destroy eggs or you must eradicate them, otherwise the impact on the ecology will be very bad.
In a word, if alien creatures are not controlled from the source, once they are brought into China, the impact on farmland, forests and other environments will be enormous. In order to avoid this phenomenon, China has also promulgated some laws, regulations and policies, which prohibit individuals and units from bringing these alien species into China without any legal approval, and are not allowed to release them privately, otherwise it will cause great damage to the ecological environment and ecosystem.
