Quantifying Differences In Habitat Use Between Anglers And Large Bluegills, Eric J. Weimer, Michael L. Brown, Brian G. Blackwell

The Prairie Naturalist

We compared the habitat use of large (>200 mm) bluegills (Lepomis macrochirus) to the locations of anglers targeting bluegills in a South Dakota glacial lake to determine whether habitat use was similar between anglers and bluegills. Eighty- five bluegills (mean total length = 213 mm) collected in September 2002 and May 2003 were affixed with external radio transmitters and subsequently relocated three to four times per week from October 2002 through October 2003. Bluegill angler locations were recorded during bluegill tracking sessions and roving creel surveys. Habitat variables (water depth, vegetation density and height, and substrate type) were measured …
