Influence of fine sediment on Arctic grayling ( Thymallus arcticus ) egg survival and spawning habitat suitability
The Arctic grayling (Thymallus arcticus) is a freshwater salmonid that is found in clear, cold waters throughout the northern regions of North America. Arctic grayling are still widespread in Alaska and Canada but have declined substantially in their two historic, disjunct southern populations in th...

The Arctic grayling (Thymallus arcticus) is a freshwater salmonid that is found in clear, cold waters throughout the northern regions of North America. Arctic grayling are still widespread in Alaska and Canada but have declined substantially in their two historic, disjunct southern populations in the contiguous United States. One of these populations was found in the AuSable River in Michigan and went extinct in the mid-1900s (Vincent 1962) while the other, found in the Upper Missouri River drainage in Montana, now inhabits a small portion of its historical range (Nelson 1954). Currently, only two native populations of Arctic grayling remain in Montana: a fluvial (stream-dwelling) population in the Big Hole River and an adfluvial (reside at least partly in lakes) population in the Red Rock Lakes drainage (Nelson 1954; Vincent 1962). These two populations are the last remaining native fluvial and adfluvial grayling populations in the contiguous United States, and are of great conservation concern (Mogen 1996; Levine 2007). |
