Distribution: North America: Probably restricted to northern Northwest Territories, Yukon Territory in Canada and Alaska in Yukon River, Paxson Lake, Copper River system, Anderson River and Mackenzie River delta. Hybridizes with Stenodus leucichthys , probably a result of simultaneous broadcasting of reproductive products in the same area; occasionally hybridizes with Coregonus sardinella (Ref. 27547 ). Belongs to the Coregonus clupeaformis complex (Ref. 27547 ).
