Recovery Strategies

Recovery Strategy for the Alberta populations of Westslope Cutthroat Trout (Oncorhynchus clarkii lewisi) in Canada

Cutthroat Trout are widely distributed throughout much of western North America. There are four major subspecies that show considerable divergence from one other and they exhibit a great deal of phenotypic variation in terms of size, colouration, and life history characteristics. Westslope Cutthroat Trout (Oncorhynchus clarkii lewisi) are the only subspecies native to Alberta. Historically, Westslope Cutthroat Trout inhabited most streams in south-western Alberta from the alpine to the prairies. Currently, genetically pure Cutthroat Trout occupy only a small fraction of the original Westslope Cutthroat Trout distribution and occur as relatively small, disconnected populations. They are largely restricted to the Rocky Mountains and foothills in the uppermost reaches of mainstem rivers and the extreme headwaters of a few major tributaries.
