Land development
"Percina" are benthic and benthic-associated fishes. "Percina sciera" belongs to the family Percidae, which along with Etheostomatinae comprise approximately 20-percent of the recognized diversity in North American freshwater fish. Land development may threaten "P. sciera" habitat. "Percina" prefer low water velocity in riffle/pool transition areas primarily on top of woody debris in a sandy/boulder substrate.
