Explore Colorado River’s Diverse Aquatic Life at Grand Canyon

Running through Grand Canyon, the Colorado River traditionally held a very large group of diverse species, possibly one of the most unique groups in North America. However, the river posed numerous challenges to the aquatic life ranging from a heavy slit load to almost freezing temperatures.
Due to these less than ideal conditions, there were only eight native fish species in the Grand Canyon. Six of these species are endemic, most of which have unique physical traits ranging from their tiny skulls and eyes to coarse skin.

See the Surviving Fish

When you visit the Grand Canyon, you can see first-hand the fish present today, which face considerable threats. Preserving the native species and their natural ecosystems is a top priority for the National Park Service Management. As you see these unique fish at Grand Canyon, you will surely appreciate the serious efforts being made by the National Park Service and its associates to protect the fish in the area.

Protecting the Native Fish

A comprehensive program has been initiated by the National Park Service with the aim of restoring native fish in Grand Canyon. These fish represent an integral part of the canyon’s unique natural ecosystems. A strong population of native fish indicates the overall health of an aquatic system; as would any healthy population indicate its habitat’s quality.
During your visit to the Park you can ask questions about the work of wildlife experts and other National Park Service professionals who are working hard to maintain and improve Grand Canyon National Park’s ecological integrity.
