Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; demersal. Temperate; 55°N - 43°N
North America: Pacific Slope from Fraser River drainage in British Columbia, Canada south through Columbia River drainage in British Columbia and in Idaho, Washington, Oregon and Nevada, USA and Harney River basin in eastern Oregon, USA.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 5723); common length : 16.0 cm TL male/unsexed; (Ref. 12193)
Inhabits lake margins; backwaters, rocky riffles and sand or silt runs of creeks and small to medium rivers. Probably feeds on algae and bottom invertebrates (Ref. 1998). Preyed upon by birds and mammals; young may be preyed upon by some salmonids (Ref. 1998). Spawning in British Columbia probably occurs late spring (Ref. 1998). Edible but not currently eaten (Ref. 1998).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.

Trophic level (Ref.
69278): 2.8 ±0.29 se; based on food items.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
