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).

Phylogenetic diversity index (Ref. 82804
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00647 - 0.01546), b=3.06 (2.93 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (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.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tm=2-4).
Fishing Vulnerability (Ref. 59153
): High vulnerability (57 of 100).
