Greenback Cutthroat Trout
Oncorhynchus
clarki stomias
Endangered Status
The Greenback Cutthroat Trout,
a subspecies of the Cutthroat Trout, is on the U.S. Endangered
Species List. It is classified as threatened in Colorado. The
decline of this subspecies can be attributed to toxic runoff from
mines, irrigation practices, development, and other modifications of
the environment, which essentially robbed it of its habitat; as well
as overfishing and the introduction of non-native fishes that prey
upon, compete with, and hybridize with the natives.
