Max length : 58.0 cm TL mâle / non sexé; (Ref. 40637); common length : 25.0 cm TL mâle / non sexé; (Ref. 12193); poids max. publié: 2.4 kg (Ref. 40637)
Inhabits clear, cool mountain headwaters and creeks (generally above 2500 m elevation), and mountain lakes. A 95% (stream km) reduction in range has resulted due to hybridization with Oncorhynchus mykiss and competition from Salvelinus fontinalis and Salmo trutta.
