The Montana Arctic grayling (Thymallus arcticus montanus) is a North American freshwater fish in the salmon family Salmonidae.The Montana Arctic grayling, native to the upper Missouri River basin in Montana and Wyoming, is a disjunct population or subspecies of the more widespread Arctic grayling (Thymallus arcticus).

The original stocks came from Georgetown Lake near Anaconda, Montana. The fluvial form of Arctic Grayling was native to the Madison and Gibbon Rivers below Gibbon Falls. In an effort to re-establish grayling in western states, over 72 million grayling eggs were harvested from Grebe Lake between 1931 and 1956 and distributed to hatcheries.
The scientific name of the Arctic grayling is Thymallus arcticus.It was named in 1776 by German zoologist Peter Simon Pallas from specimens collected in Russia. The name of the genus Thymallus first given to grayling (T. thymallus) described in the 1758 edition of Systema Naturae by Swedish zoologist Carl Linnaeus originates from the faint smell of the herb thyme, which emanates from the flesh.
The Arctic Grayling (Thymallus arcticus montanus) was originally distributed throughout the Madison River drainage below Firehole Falls and Gibbon Falls and the Gallatin River drainage. Introductions of brown and rainbow trout into the Madison River drainage caused the extirpation of the grayling from these rivers.
The two populations are commonly called Montana Arctic grayling. [4] The Big Hole River Watershed Committee (BHWC) was formed in 1995 by several Big Hole ranchers and some factions of the conservation community who opposed an ESA listing for fluvial Arctic grayling.
The forest is also home to grizzly bear, cougar, Canadian lynx, bald eagle, bull trout, Arctic grayling, and gray wolf, the latter being a migrant from northern Montana and the Yellowstone wolf reintroduction program in Wyoming. Elk, mule deer, moose, bighorn sheep, pronghorn, coyote, and black bear are more commonly seen.
The two subranges are quite different from each other in appearance. The East Pioneers have rugged, heavily glaciated peaks. About 145,000 acres (59,000 ha) of the East Pioneers are roadless, and the range holds more than 30 high lakes, including Grayling Lake, which contains Arctic grayling. [2]
Thymallus, commonly known as graylings, is a genus of freshwater ray-finned fish and the only genus within the subfamily Thymallinae of the family Salmonidae.Although all Thymallus species can be generically called graylings, without specific qualification the term "grayling" typically refers to the type species Thymallus thymallus, the European grayling.
