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

North America: widely occurs from coast to coast of north-central North America: in the east along the mountains to Virginia; in the Mississippi drainage south to Iowa; in the western basin south to northern Mexico; reported from northeastern Nevada; in the inshore waters in all the Great Lakes (Ref. 1998).

Biology     Glossary (e.g. epibenthic)

Inhabit rubble and gravel riffles (sometimes runs and pools) of fast creeks and small to medium rivers; also in rocky shores of lakes (Ref. 5723). Young up to 4 months are pelagic (Ref. 1998). Form schools (Ref. 1998). Feed on mayflies, blackflies, and midges (Ref. 1998). Spawn over pits in loose gravel substrate (Ref. 51972). Widely used as bait in the USA (Ref. 1998). Artificially propagated in Minnesota, USA in long narrow ponds having weak water flow (Ref. 1998).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00267 - 0.01297), b=3.07 (2.88 - 3.26), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.40 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=2; tmax=5; Fec = 1,155).
Vulnerability (Ref. 59153):  Moderate vulnerability (36 of 100) .
Price category (Ref. 80766):   Unknown.
