Effects of Environmental Factors and Sport Fisheries Management Practices on Largemouth Bass (Micropterus Salmoides) Fluctuations in Abundance in Illinois Inland Lakes

Linear regression was used to analyze predictors' effects on the response variables. Each anthropogenic predictor was analyzed for main effects and first-order interactions with the environmental predictors. Multiple-lake (for broad-based treatment effects) and lake-specific analyses of the anthropogenic component were performed. Anthropogenic factors accounted for more variability in response variables than environmental factors. The age-1 response variable decreased the first year and increased the second year following lake rehabilitation. The adult response variable increased following the imposition of all length limits. None of the predictors analyzed accounted for differences in lake productivity. Recruitment at age-2 correlated only with age-1 abundance.
