The fishes of Champaign County : final report

Stream fishes in the six drainage basins of Champaign County, Illinois were quantitatively sampled from June 1987 through October, 1988. Species richness and composition were compared to three historical fish surveys that also sampled the same locations between the late 1890's through 1960 at approximately a thirty year interval. Data on land use, water quality, physical habitat, benthic macroinvertebrate abundance, crayfish distribution and abundance and prey utilization of several sportfish were also assessed and related to the abundance and distribution of sport fish populations in an attempt to identify limiting factors. The land use/cover conditions in Champaign County during the 1950's were quantified and compared to those that existed during the present survey in an attempt to identify potential land use changes that may be associated with the distribution and abundance of sportfish populations.University of Illinois Urbana-Champaignunpublishednot peer reviewedOpe
