COSEWIC Assessment and Status Report on the Bull Trout Salvelinus confluentus in Canada
Bull Trout is a large char. This salmonid derives its name from its large head and jaws. Bull Trout are olive-green to blue-grey in colour and pale round spots on their flanks and back distinguish them from most other similar-looking salmonids. It is difficult to visually distinguish them from Dolly Varden char, however, and detailed measurements or genetic analyses are required for accurate identification where their ranges overlap. Because of its very specific habitat requirements, this sportfish is highly sensitive to habitat changes. Bull Trout are, therefore, viewed as an indicator species of general ecosystem health. Based on genetic analysis, range disjunction and distribution across National Freshwater Biogeographic Zones, five designatable units are recognized; Genetic Lineage 1 (Southcoast BC populations) and Genetic Lineage 2 (Western Arctic, Yukon, Saskatchewan-Nelson and Pacific populations).
