According to the given situation, the Gila trouts being the native species has been affected by the non-native Rainbow trout. This may be because of the fact that non-native species can be invasive for the native species. As the species is used as mate by the non-native species and they may become the prey of non-native species. This has resulted in the extinction of the species of Gila trouts.
