A slow-growing fish which inhabits rivers. A cold water fish and never goes to the ocean; finds deep cold waters during summer; can be found under the ice in late fall and winter (Ref. 12218).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00607 - 0.01371), b=3.07 (2.95 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Niveau trophique (Ref. 69278):  3.8   ±0.3 se; based on diet studies.
Generation time: 13.7 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Résilience (Ref. 120179):  Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (tm=2-4).
Fishing Vulnerability (Ref. 59153):  High vulnerability (57 of 100).
Catégorie de prix (Ref. 80766):   Very high.
