» Life History

Habitat Requirements

Relatively low-silt substrates in good flows; forages commonly on bedrock, boulders, cobble. Generally schools with white-tailed shiners and other mid-water species, but generally remains close to the bottom. Sub-adult chubs appear more commonly on smaller substrates like sand and small gravel than do adults.

Food Habits

Small insect larvae, predominantly chironomid; some mayflies. Unlike most other cyprinids (shiners), feeds benthically on relatively silt-free substrates, using a head-oriented-down poster and a sewing-machine-like motion to pick larvae.

Movement / Home Range

In fall and winter, primarily young individuals will move up small trib streams from source mainstem populations (e.g., Little Tennessee R., NC). Spawning probably does not occur in small tribs.

Reproductive Strategy

A crevice spawner, depositing eggs in relatively silt-free crevices in bedrock or between larger rocks. Nuptial males highly territorial, defending prime spawning sites from rival males.

Other

Population size appears to fluctuate fairly significantly based on multi-year sampling in Little Tennessee R., NC. Interrelationships between the seasonality of flows and temperature probably dictate recruitment and ultimately overall population size year to year. Year 9 of a 10-year population monitoring study in the Little Tennessee R. has been completed (August 2015).
