Distribution
North America and Asia: Arctic drainages from Anderson River in Northwest Territories, Canada to Kuskokwim River (Bering Sea tributary) in Alaska. Upstream in Mackenzie River and Yukon River drainages to British Columbia, Canada. Isolated population occurs in northern Caspian Sea and inflowing rivers. Populations from Kazakhstan, Russia and probably Azerbaijan are endangered. Hybridization with Coregonus nelsoni, Coregonus autumnalis and Coregonus muksun are due more to the broadcasting of eggs and sperm rather than pairing between species or genera.
