In Aug 1994, 18% of the total plant biomass in Fish Lake, Dane County, Wisconsin, was removed in a radial pattern of 2-m-wide channels. Largemouth bass and bluegill abundance, survival, growth, and length frequency were compared between pretreatment (1992–1993) and posttreatment (1995–1996) years. Following vegetation removal, mean abundance of largemouth bass and bluegill did not change significantly, but growth increased for age-2–4 largemouth bass and declined for age-5 largemouth bass and age-4–5 bluegills. Survival increased for age-2, −3, and −5 largemouth bass and age-4–6 bluegills. Population size structure increased for both species. We conclude that removal of Eurasian watermilfoil may increase growth and survival of some age-groups of centrarchid populations without altering the abundance of either species. However, this study lacked replication and control that is needed to separate effects of plant harvesting from effects of other biotic and abiotic factors. References T. D. Beard, 1982.
