20 Yr Government Endangered Trout Restoration Project A Failure

Exotic Animal Newsflash:

greenbackcutthroattrout.JPGIt 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 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.

Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Salmoniformes
Family: Salmonidae
Genus: Oncorhynchus
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.

What Can You Do?
1. Be educated as to what this fish looks like if you fish in these river areas. If you catch one of these trout, release it immediately.
2. Help support local and worldwide animal conservation organizations.
