Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 72.0, range 58 - 86 cm
Max length : 103 cm TL 雄魚/尚未辨別雌雄; (Ref. 40637); common length : 62.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 12193); 最大體重: 14.5 kg (Ref. 4699)
Occurs in deep pools of large cold rivers and lakes (Ref. 5723). Most common in high mountainous areas where snowfields and glaciers are present (Ref. 5723). Rarely anadromous (Ref. 5723, Ref. 51243). Lacustrine form matures in lakes and spawns in tributaries, where young reside for one to three years (Ref. 10367).
