Max length : 185 cm TL オス/雌雄の選別がない; (Ref. 44724); 156.0 cm TL (female); common length : 60.0 cm TL オス/雌雄の選別がない; (Ref. 9258); common length :100 cm TL (female); 最大公表体重: 25.0 kg (Ref. 11115)
Commonly found in lakes and rivers (Ref. 9258). Inhabits stony rivers (Ref. 9072). Migrates to the sea to breed. Oviparous (Ref. 205). Marketed fresh, smoked and frozen; eaten fried and broiled (Ref. 9988). Reports of reaching up to 2 meters and 50 kilograms are rare and more common historically; in recent times, only a few exceed 120 cm TL (Ref. 82796).

Estimates based on models
Preferred temperature (Ref.
123201): 10.6 - 18.3, mean 15.1 °C (based on 138 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00093 (0.00076 - 0.00115), b=3.20 (3.15 - 3.25), in cm total length, based on LWR estimates for this species (Ref.
93245).
栄養段階 (Ref.
69278): 4.5 ±0.5 se; based on diet studies.
回復力 (Ref.
120179): 非常に低い, １４年以上の倍増期間の最小個体群 (Tmax=60; tm=10-48 years based on age-length relationship.).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (90 of 100).
