Susan Marcquenski

Fish Health Specialist | WDNR Retired

While an undergrad at the University of Illinois-Urbana, Sue discovered the fascinating ecology of parasites.
She pursued this learning adventure at UW-Stevens Point where she studied the Wisconsin distribution and
prevalence of a parasite of ruffed grouse which was partially funded by the WI DNR. Opportunities to work
with the fish and wildlife health specialists at DNR opened up, and several years later, Sue was offered the fish health specialist position in Fisheries Management. This was a dream job where she learned a “metric ton” from colleagues in Wisconsin, the USA and beyond, and was able to contribute new knowledge to the field of aquatic animal health before retiring after 30+ years of service. In retirement, Sue still holds service as a high priority and continues to assist fish farmers with health inspections, improving rearing conditions that promote fish health and finding solutions to fish farming challenges. She is honored to be part of FLOW’s Science Team, which keeps her in contact with the Riverway, its people and challenges, and offers the chance to influence the River’s future through science.
