Biology

Species Biology

Inhabits muddy pools of headwaters, creeks and small rivers (Ref. 1739). Also found in ponds and lakes (Ref. 10294). Tolerates unsuitable conditions (e.g., turbid, hot, poorly oxygenated, intermittent streams) (Ref. 1739). Feeds on detritus and algae (Ref. 10294). Introductions consequently caused the spread of the enteric red-mouth disease throughout northern Europe which infected wild and cultured trouts and eels (Ref. 1739). Maintained a relatively high metabolic rate and level of activity under hypoxic conditions (Ref. 77050). Individuals that survived the hypoxic conditions during winter had rapid growth rates after ice-off (Ref. 77048).

Distribution

BC Distribution and Notes

The first B.C. introduction of this Great Plains minnow was probably via a “bait bucket” into Two Island Lake near Tupper, B.C. Since the original introduction it has turned up in the Fraser Valley and elsewhere in the province. They are usually associated with heavy vegetation and low oxygen conditions.

North America: Over much of North America from Quebec to Northwest Territories, Canada and south to Alabama, Texas and New Mexico, USA. Also in Mexico. Several countries report adverse ecological impact after introduction. Asia: Iran (Ref. 39702).
