Abstract: A total of 18,361 specimens belonging to 34 species and 6 families was examined for external morphological anomalies. Forty-seven defective fishes (0.26%) were found. The most widespread abnormality was spinal curvature, occurring 16 times in 5 species. Deformed or missing fins were found in 10 specimens of 4 species. Two deformed mouths were recorded from 2 species, and one specimen had an incomplete operculum. There were 18 cases of pugheadedness in Pimephales notatus. The frequency of anomalies in this undisturbed community agrees well with figures in the literature for other areas. This information is intended to serve as base line data for future studies of Cedar Fork Creek.
