In addition to being the Director of the North Central Regional Aquaculture Center (NCRAC), my research addresses both aquaculture and fishery management issues. I also serve as the Aquaculture and Fisheries Specialist for Iowa State University Outreach and Extension program.
My research focus on two general fisheries topics, aquaculture and pond management. The aquaculture research focuses on the fish species appropriate for the Midwest. Fisheries research focuses on fisheries management, aquatic vegetation management, water quality issues as well as general aquatic ecology questions. A unique aspect of my integrated extension/outreach and research program is my role as Director of the North Central Regional Aquaculture Center (NCRAC) where I manage and lead various research and extension/outreach programming activities from this important federally supported entity. NCRAC's mission is to enhance aquaculture through education, research, and technology transfer to support a sustainable profitable industry.
