Research

Dr. Summerfelt's has diverse research interests in fish biology (telemetry, age and growth, physiology, diet, reproductive biology, parasites), aquaculture, aquatic toxicology, water quality, aquacultural effluents, ecology and management of winterkill lakes, lake aeration, and fishery management. Before retirement he participated in the interdepartmental programs in Toxicology and Water Resources. His speciality is represented by more than 40 articles authored by he and his students on culture of walleye.

He has edited and authored several chapters in the Walleye Culture Manual, and written three reviews on culture of walleye:
