Range and Identity
Percina roanoka occurs naturally in the Roanoke, Neuse and Tar drainages of Virginia and North Carolina. Records in parts of the upper James and New systems have been considered likely introductions. That uncertainty should remain visible rather than presenting every locality as unquestionably native.
Habitat and Behavior
Adults inhabit fast gravel and rubble riffles in small to medium rivers. Young are recorded in gravel-bottomed pools and runs close to riffles. These adjoining habitats can support different stages, so a survey’s location within the channel affects which fish it encounters.
Food and Life History
The maximum reference is 7.8 centimeters total length, with 4.3 centimeters given as a common size. The available account does not establish an independent maximum weight or a detailed diet. A breeding schedule from another regional darter is not substituted.
Field Note
Keep life stage with the channel description. A small fish beside a riffle and an adult in faster water can represent complementary parts of the species’ habitat use.
