List of fishes native to Arizona

Arizona is known to have climate ranging from dry and hot at lower elevations to cold weather on the high mountains.

Habitat loss and alteration, and the introduction of non-native fish species have caused sharp declines in many native populations.

The state of Arizona first placed native fish on the endangered species list in 1988; however, detrimental human activities including aquifer pumping, reduction in stream flows, and predation from non-native green sunfish, have acted as major contributing factors to the decline of these native species.

The largest standing bodies of water in Arizona includes lakes Powell, Mead, Mohave, and Havasu, all are formed by impoundment of the Colorado River mainstream.

Small reservoirs are generally most common at intermediate and high elevations, and developed in many cases for recreational purposes.
