The habitat utilization and movements of largenouth bass (Micropterus salmoides), yellow perch (Perca flavescens), bluegill (Lepomis macrochirus) and pumpkinseed (Lepomis gibbosus) were studied via radio telemetry. Habitat utilization was calculated as the percentages of a tracking day each fish occurred in each habitat, weighted by the proportionate area of each habitat. The five habitats were heavy macrophyte (H), primarilyMyriophyllumsp.; light macrophyte (L), primarilyPotamogetonsp.; sand (S); open water (O), having an approximate minimum depth of 6 m and no macrophytes; ecotone (E), which was defined as 1.5 m on each side of a boundary between macrophyte beds and sand or open water. Movement speeds were determined by calculating the distance between two tracked locations at five minute intervals.
