Populations of Perca flavescens (yellow perch) and Lepomis macrochirus (bluegill) in Crooked Lake of Noble County, Indiana have been found to have had substantial variations in abundance over the past 17 years. While yellow perch has drastically decreased in abundance, bluegill abundance has increased during the same period of time. A comprehensive literature research was done to see if other lakes had seen similar trends. It was found that parts of the Great Lakes also saw declines in yellow perch.
