Our knowledge of the distribution of most Wisconsin nongame fishes is limited because they have not been frequently surveyed. Between 1974 and 1980, the Wisconsin Department of Natural Resources (WDNR) conducted the Fish Distribution Study. More recently, the WDNR began a new statewide fish survey in part to allow a rewrite of the landmark Fishes of Wisconsin book. This chapter compares the results of these two surveys to examine how nongame fishes have declined in selected small streams and lakes in the southernmost quarter of Wisconsin. This region is generally the most densely populated with a landscape dominated by intensive agriculture and urbanization. Although some high-quality aquatic ecosystems remain, findings suggest that, if current trends continue, the future of these ecosystems is precarious. A conservation strategy is proposed to help protect these ecosystems and their fish faunas.
