» Life History

Habitat Requirements

Relatively silt-free substrates of sand, gravel, and cobble in good flows of smaller streams. Occurs in shallow shoals as well as deeper runs in Clinch R.

Food Habits

Suspension feeder on plankton; deposit feeder on bacteria and organic matter in substrate.

Movement / Home Range

Sedentary.

Reproductive Strategy

Separate sexes, males releasing sperm to water column, where females uptake while filter-feeding/respiring. A short-term brooder, meaning spawning season lasts a few weeks typically in late spring to summer. Specialized larvae termed glochidia brooded in females gills; glochidia require host fish for several week parasitic stage on gills. Cyprinids serve as fishes, which females attract by releasong conglutinates, aggregates of glochidia packaged in a mucilagenous matrix, that typically resemble fish prey.
