Exotic Animal Newsflash:
It was reported last week that for the past 20 yrs, there has been an effort in Colorado to restore an endangered native
trout, the Greenback Cutthroat Trout, but studies show that in some of the waterways, the wrong trout was stocked.
The more common Colorado River cutthroat trout was used mistakenly, as they look similar.
The Greenback Cutthroat Trout is shown in the photo above. The more common Colorado River Cutthroat Trout is shown in the photo to the right.
The University of Colorado lead a 3yr study that shows this effort has been a failure in improving the status of the greenback cutthroat trout subspecies.
This trout is native to drainages of the South Platte and Arkansas rivers in Colorado, and a small part of Wyoming.
The greenback cutthroat trout was actually declared extinct
in 1937, due to pollution, competition from non-native species of fish and, of course, overfishing. However, some remnant populations were found in the 1950s in tributaries, and were then used in federal and state hatcheries in an effort to repopulate their native habitat. This subspecies was then added to the endangered species list in 1978.
This is a huge blemish on the face of the study, but let’s all hope that the government, nonetheless, moves ahead to help repopulate this threatened subspecies before it’s too late and it officially goes extinct.

Species: O. clarki
Subspecies: O. c. stomias
This subspecies of trout now occupies less than 1% of it’s historical range. This subspecies of the cutthroat trout has the largest spots, and has the most brilliant spawning coloration.
