In 2018 Wildlife biologists noticed something odd about cutthroat trout they were finding on private properties in Southwestern Colorado. The fish they were collecting didn’t look like the cutthroat subspecies they expected to find. Instead, they had rediscovered 8 small populations of subspecies in the Colorado Cutthroat Trout family. The fish were thought to have been extinct, but after DNA testing, the biologist’s hypotheses proved to be true, the fish were indeed the once-thought-lost subspecies.

To ensure the populations continue to grow unimpacted, CPW will not be releasing the locations where the fish were found.

From the Durango Herald:

“’Anyone who just looked at these fish would have a difficult time telling them apart from any other cutthroat; but this is a significant find,’ said Jim White, an aquatic biologist for CPW in Durango, in a prepared statement.

‘Now, we will work to determine if we can propagate these fish in our hatcheries and reintroduce them into the wild in their historic habitat. It’s a great conservation effort and a great conservation story,’ he said.”
