Research Areas

Most of my research projects deal with aquaculture, aquaponics and fisheries ecology in the Midwest. I examine the practice of fish culture and physiological behavior of cultured WI fishes. Current projects include topics such as recirculating aquaculture production of Midwest fish, fish-pond trophic dynamics, development of new cultured fish strains, new aquaculture technologies, and aquatic diseases. As Director of the Northern Aquaculture Demonstration Facility (NADF) I oversee research, education, and outreach projects where we strive to get applied research results directly to fish farmers and into the hands of future aquaculturists. This includes projects involving online education, beginning aquaculture workshops, technology transfer, and biosecurity. Full project listings can be found here:
