Species often confused with {name}
Bull Trout
Salvelinus confluentus
Key differences: Bull Trout typically have larger, more widely spaced pale spots, a larger head, and a more robust body. Their spots are often yellow to orange, rarely red. The range of Bull Trout is generally more southerly and inland in North America, though there is overlap. Genetic analysis is often required for definitive identification in areas of sympatry.
Arctic Char
Salvelinus alpinus
Key differences: Arctic Char generally have fewer, larger, and more intensely colored spots (often red or orange) than Dolly Varden. Their body shape can be more elongated. Arctic Char are typically found in more northerly, colder waters, often in landlocked populations or anadromous forms in Arctic and sub-Arctic regions. Overlap in appearance and range can occur, particularly in Alaska and northern Canada.
Brook Trout
Salvelinus fontinalis
Key differences: Brook Trout have distinctive worm-like markings (vermiculations) on their back and dorsal fin, which Dolly Varden lack. They also have red spots with blue halos (areolae) on their sides, a feature absent in Dolly Varden. Brook Trout are native to eastern North America but have been widely introduced.
