Comment period winding down on USNPS proposals to control invasive fishes in Grand Canyon NP

Rising numbers of invasive brown trout and green sunfish in the Colorado River downstream of Glen Canyon Dam have spurred the National Park Service to propose a range of new actions to control those and other non-native aquatic species in Glen Canyon and Grand Canyon.


But a few of the ideas, including long-term electrofishing and the introduction of more non-native fish to the river, are drawing concern from fishing and environmental organizations as well as the Arizona Game and Fish Department.
