Teleostei (teleosts) > Salmoniformes (Salmons) > Salmonidae (Salmonids) > Salmoninae
Etymology: Salvelinus: Old name for char; it is the same root of german "saibling" = little salmon (Ref. 45335).

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; brackish; benthopelagic. Temperate; 61°N - 39°N

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Coastal and mountain streams of Arctic, Pacific, and Missouri River drainages from extreme southern Yukon in Canada to headwaters of Columbia River drainage in northern Nevada, USA, and McCloud River drainage in northern California, USA.

Length at first maturity / Size / Weight / Age

Maturity: Lm 72.0, range 58 - 86 cm
Max length : 103 cm TL male/unsexed; (Ref. 40637); common length : 62.5 cm TL male/unsexed; (Ref. 12193); max. published weight: 14.5 kg (Ref. 4699)

Biology     Glossary (e.g. epibenthic)

Occurs in deep pools of large cold rivers and lakes (Ref. 5723). Most common in high mountainous areas where snowfields and glaciers are present (Ref. 5723). Rarely anadromous (Ref. 5723, Ref. 51243). Lacustrine form matures in lakes and spawns in tributaries, where young reside for one to three years (Ref. 10367).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00473 - 0.02021), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.7   ±0.57 se; based on food items.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (62 of 100).
Price category (Ref. 80766):   Very high.
