Ecological and biological traits of non-native freshwater fish species differentiate them from native species in China

China’s freshwater ecosystems are gradually invaded by an increasing number of non-native fish species. However, to date, some controversy about the number of native and non-native freshwater fish species in wild habitats and very limited information on ecological or biological traits mediating fish...
