Abstract

This study elucidated the origin of the alligator gar (Atractosteus spatula) by investigating the traces of the alligator gars in various waters in different provinces and cities of China. Alligator gars originally entered China through ornamental fish trade (illegal smuggling). They are abandoned by people probably because it is difficult to raise them, or released by people out of "goodwill". Therefore, the invasion sites of alligator gars are mainly concentrated in the waters of the residential districts and the lakes of the parks. The invasion of alligator gars has brought potential threats to the aquatic ecosystem in China. Through reading the literature and regulations, this study found that alligator gars are not included in the list of alien invasive species at present. However, according to the overwintering ability and damage degree of alligator gars, some experts have suggested that it should be included in the list of alien invasive species. This study also put forward its own views on the proper treatment of the alien species alligator gars.
