The Arctic grayling is a cold-water fish belonging to the trout and salmon family with a distinctive, sail-like dorsal fin. Found in Montana, they depend on cold water to complete much of their life cycle and serve as an indicator species of healthy rivers. This video tells the story of a team of biologists searching for signs of the elusive grayling on a national wildlife refuge in Montana.
Don’t grayling and cutthroat coexist successfully? I found the large harvest of cutthroat in Red Rock shocking – I didn’t know they were (are?) doing that.
A current project on the upper Gibbon River and headwater lakes in Yellowstone National Park has the goal of creating populations of both grayling and westslope cutthroat trout.
