Maturity: Lm ? range ? - ? cm
Max length : 120 cm TL オス/雌雄の選別がない; (Ref. 56527); 最大公表体重: 15.0 kg (Ref. 56527); 最大記録サイズ: 9 年 (Ref. 56527)
The land-locked form prefers low temperature streams, below 15°C. Young of the sea-run form enter the sea at 2 years of age and return to the rivers for spawning when they are 4 years or older. Found in summertime water temperature of 13-15° C (Ref. 12218). Carnivore, feeding on insects and plankton (Ref. 12218). Utilized fresh, smoked and frozen; can be broiled, microwaved and baked (Ref. 9988). Two forms: the land-locked form which reaches 35 cm, and the ocean form of 70 cm (Ref. 9137).
Distinct pairing (Ref. 205).
