Steelhead Trout (Oncorhynchus mykiss), Thompson River and Chilcotin River populations in Canada, 2018: COSEWIC Technical summaries and supporting information for emergency assessments
In British Columbia, Oncorhynchus mykiss occurs as two evolutionary lineages, commonly referred to as “coastal” and “interior” O. mykiss. Both lineages of O. mykiss are found in freshwater-resident and anadromous (sea run) populations or life-history types, known as Rainbow Trout and Steelhead Trout, respectively. Interior O. mykiss are found in the Thompson-Chilcotin rivers (part of the Fraser River drainage). There is some interbreeding between freshwater-resident and anadromous individuals and freshwater-resident individuals may produce anadromous offspring and vice versa.
