Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri
North America: throughout most of Canada to the Atlantic Coast, south through North Carolina to New Mexico in the USA, becoming less common in the southern High Plains.
Inhabits a wide range of habitats, from rocky pools and riffles of headwaters to large lakes. Usually occurs in small, clear, cool creeks and small to medium rivers. May be found at a depth greater than 45 m (Ref. 1998). Moves to shallower water near sunrise and sunset to feed. Fry (1.2 cm in length) feed on plankton and other small invertebrates; bottom feeding commences upon reaching a length of 1.6-1.8 cm. Preyed upon by birds, fishes, lamprey, and mammals (Ref. 1998). Flesh is white, flaky, and sweet (Ref. 1998).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01229 (-0.03401 - 0.05859), b=2.99 (2.96 - 3.02), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278): 2.8 ±0.4 se; Based on diet studies.
Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (tm=6; tmax=12).
Vulnerability (Ref. 59153): High vulnerability (57 of 100) .
