Assistant Extension Professor, University of Minnesota Sea Grant


Dr. Amy Schrank is a fish ecologist studying how hybrid cattail affects fish communities in lake ecosystems. Her research also focuses on how human effects such as dams and increased water temperature affect movement patterns of stream fishes. In addition to research, she also collaborates with fisheries and aquaculture researchers and stakeholders around Minnesota to provide research support and a bridge to communicate technical information to stakeholders, managers, and the public.
