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

North America: St. Lawrence-Great Lakes system, Hudson Bay and Mississippi River basins from southern Quebec in Canada to North Dakota and south to northern Alabama and eastern Oklahoma in the USA. Introduced into many countries for sport fishing. Several countries report adverse ecological impact after introduction.

Inhabit shallow rocky areas of lakes, clear and gravel-bottom runs and flowing pools of rivers, cool flowing streams and reservoirs fed by such streams (Ref. 1998). Young feed on plankton and immature aquatic insects while adults take in crayfish, fishes, and aquatic and terrestrial insects (Refs. 1998, 10294, 44091). Sometime cannibalistic (Ref. 30578). Preyed upon by fishes and turtles (Ref. 1998). Excellent food fish (Ref. 1998).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01080 (-0.03603 - 0.05763), b=3.06 (3.02 - 3.09), based on LWR estimates for this species (Ref. 93245).

Trophic Level (Ref. 69278): 3.2 ±0.4 se; Based on diet studies.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.10-0.28; tm=3-6; tmax=14; Fec=5,000).

Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100) .

Price category (Ref. 80766): Unknown.
