The reproductive biology of the Roanoke bass is largely unknown, but is considered to be similar to that of the rock bass. During the spawning season, from mid-May to mid-June, the male builds a nest in unvegetated shallows over gravel substrates and guards it from intruders (10). Maturity occurs at approximately two years old, typically when the Roanoke bass has reached a total body length of 15 centimetres and a body weight of 75 grams (9). Populations appear to be dominated by large juveniles and adults, suggesting that reproductive rates, and/or survival rates of young juveniles, within this species may be low (3) (8) (9).
As with other species in the Centrarchid family, the Roanoke bass is a carnivorous fish, preying on small aquatic invertebrates when young and consuming an increasing amount of crayfish as it matures (9).
Throughout many parts of its range, the Roanoke bass occurs alongside the morphologically similar rock bass. Although each species has slightly different habitat requirements, the rock bass is considered a better competitor for prime habitat. These two species are also known to hybridise (2).
