Abundance, growth and food of yellow perch (Perca
flavescens) were studied from 1974-1976 to evaluate the
effects of a tertiary wastewater treatment plant which
began operation in 1973 on eutrophic Shagawa Lake, Ely,
Minnesota. Trawl, seines and gill nets were used in
sampling. No conclusive results were obtained to relate
tertiary wastewater treatment to changes observed in
abundance, growth and food of yellow perch in Shagawa
Lake.
