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

North America: St. Lawrence-Great Lakes, Hudson Bay, and Mississippi River basins from Quebec to Alberta in Canada, and south to northern Alabama and Louisiana in the USA. Introduced into Atlantic, Gulf and southern Mississippi River drainages.

Biology     Glossary (e.g. epibenthic)

Inhabit sand and gravel runs, sandy and muddy pools and backwaters, of small to large rivers; less often in lakes and impoundments (Ref. 10294, 11003). Larvae feed on cladocera, copepods, and midge larvae, while juveniles consume fishes (Ref. 10294). Spawn between March and June (Ref. 10999) in pairs or small aggregations (Ref. 11003).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00332 - 0.01144), b=3.14 (2.96 - 3.32), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.1   ±0.68 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.23; tmax=7).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100) .
