Max length : 58.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 40637); common length : 25.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 12193); 最大体重: 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.
栖息于清澈寒冷的山河源上游与小溪 (通常在上面 2500 公尺海拔), 与高山湖泊中。 95%(水流公里) 分布范围的缩减用来自 美洲红点鲑［溪红点鲑］［Salvelinus fontinalis］ 与 斑鳟属 trutta 的 Oncorhynchus mykiss 与竞争起因于杂交.
