This project was conducted to measure the response of the warmwater fish populations in Shagawa Lake, Minnesota, to altered trophic conditions brought about by phosphate removal from sewage discharges entering the lake. The project also served to provide basic information on the mechanisms through which a lake's trophic status controls its fish species complex. Abundance, distribution, growth, and feeding interrelationships of walleye (Stizostedion vitreum), northern pike (Esox lucius), yellow perch (Perca flavenscens), and lake herring (Coregonus artedii) were described in relation to changes in prey density and other environmental factors.
