Distribution and Taxonomy of Fishes in the Mackenzie Drainage of British Columbia
New and previously published records are listed for 28 species of freshwater fishes in tributaries of the Mackenzie River in northern British Columbia. Distribution patterns are discussed for all species reaching the continental divide at the Peace River headwaters; some are restricted to one or oth...
