ABSTRACT Bluegill ( Lepotmis macrochirus ), largemouth bass ( Micropterus salmoides ), white catfish ( Ictalurus catus ), and channel catfish ( Ictalurus punctatus ), collected from an electric power plant cooling reservoir and a municipal water supply reservoir near Roxboro, North Carolina, were analyzed for selenium concentrations in axial muscle, reproductive and liver tissues. Fishes from the municipal water reservoir had lower selenium concentrations (≤0.2‐2.1 μg/g ‐ wet weight) than found in the cooling reservoir fishes (1.6‐70.0 μg/g ‐ wet weight) but similar distributions of concentrations among the tissues was evident. Selenium was differentially accumulated, with higher concentrations in liver tissues (0.7‐70.0 μg/g ‐ wet weight), followed by female reproductive tissues (0.7‐25.0 μg/g ‐ wet weight), axial muscle tissues (≤0.2‐23.0 μg/g ‐ wet weight) and male reproductive tissues (0.2‐7.2 μg/g ‐ wet weight).
