Length at first maturity / Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 70.0 cm TL male/unsexed; (Ref. 40637); 60.0 cm TL (female); common length : 55.0 cm SL male/unsexed; (Ref. 35840); max. published weight: 8.0 kg (Ref. 12218)

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). Feeds on larval and adult insects, amphipods, small fish, frogs, mice and salmon spawn (Ref. 593). During spawning the body turns to a dark red and the dorsal and pectoral fins change to a rainbow of colors (Ref. 12218).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00673 - 0.01706), b=3.06 (2.92 - 3.20), 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.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (tm=2-4).

Prior r = 0.3, 2 SD range = 0.11 - 0.78, log(r) = -1.2, SD log(r) = 0.48, Based on: 1 K, 6 tgen, 1 Fec records

Vulnerability (Ref. 59153): High to very high vulnerability (68 of 100) .

Price category (Ref. 80766): Very high.
