Range Extent20,000-200,000 square km (about 8000-80,000 square miles)
Number of Occurrences81 to >300
Rank Reasons
Widely distributed and abundant in the Ohio River basin, but pollution has caused disappearance from some areas.
Range Extent Comments
This species is widespread in the upper and middle Ohio River basin, exclusive of the New River drainage, southwestern New York, western Pennsylvania, and western Virginia (very rare) to southern Indiana and eastern Kentucky; it occurs only below Kanawha Falls in the Kanawha River system, West Virginia (Page and Burr 2011).
Occurrences Comments
This species is represented by a large number of occurrences (subpopulations).
Lee et al. (1980) mapped about 150 collection sites.
Threat Impact Comments
These darters have disappeared in areas of heavy domestic, industrial, or agricultural pollution (Lee et al. 1980). In some areas, threats include siltation and acidification of streams from coal mining wastes (Burkhead and Jenkins 1991).
Ecology & Habitat

Habitat

Habitat includes swift gravel and rubble riffles of small to medium rivers (Page and Burr 2011); typically this darter occurs in rubble-boulder-gravel riffles with some sand; individuals move downstream to deep riffles and pools for winter. Eggs are laid in sand and small gravel on the downstream side of large rocks near riffles.

Reproduction

Spawns April-May in Ohio, probably May and June in Pennsylvania. Eggs hatch in 13-14 days at 10-22 C. Sexually mature in 2 years, lives to maximum of 3+ years.
