We sampled fishes from eight creeks within the Bull and Upatoi creeks watershed in the summer months of June 2001 and August 2002 to provide a checklist of common fishes. This sample and its data support a more comprehensive study by the authors documenting an urbanization gradient among creeks and their associated differences in fish assemblage structure within this aquatic system. However, here we provide a simple, but useful, checklist of common Cyprinid and Centrarchid fishes to enhance future species-monitoring efforts within this watershed. We collected a total 2407 individuals representing 34 species from Lindsey, Cooper, Flatrock, Bull, Dozier, Randall, Kendall, and Baker Creeks by seining. Leponns macrochirus (Bluegill), Cyprinella venusta (Blacktail Shiner), and Notropis buccatus (Silverjaw Minnow) were the most abundant species within the Bull and Upatoi creeks watershed. Conversely, Pimephales promelas (Fathead Minnow) and Pimephates vigi lax (Bullhead Minnow) were the rarest. We calculated and present species richness (S), total abundance (TA), Shannon-Weiner diversity index (H'), maximum species diversity (H'max), and species evenness (J') for all eight creeks within the watershed. Additionally, we discuss stream characteristics, related microhabitat use by fishes within the watershed, and the potential influences of an urbanization gradient on fish assemblage structure.
