Effective management of Minnesota’s fisheries relies on access to the best available science to inform decisions. The fisheries research unit consists of researchers and support staff who work in area fisheries offices statewide.
Staff conduct applied research that evaluates management practices; develops new management tools and sampling techniques; and anticipates responses of fisheries to new and existing stressors.
Big cats inhabit the Minnesota
A three-year study of Minnesota River flathead catfish between Mankato and Shakopee showed an abundant population of large fish topping 20 inches.
Are perch getting smaller?
A project designed to find out why the number of yellow perch are declining in fish population counts continues this summer in 25 Minnesota lakes.
Monitoring shows healthier, happier trout
Data collected as part of the DNR's ongoing long-term stream monitoring program help explain southeastern Minnesota's abundant brown trout.
Tracking change for the future
Since 2008, an intensive lake ecosystem monitoring program has detected and analyzed changes in key Minnesota lakes.
Investigational reports: Minnesota DNR fisheries section publications for research studies that have more local or regional management implications.
Special publications: DNR manuals, lake management plans, guidelines or reviews.
Peer-reviewed publications: Research studies that are published in scientific journals and have gone through a rigorous peer review process. Results of these studies influence fisheries management beyond Minnesota. Copies of these reports can usually be received by contacting the author.
Fisheries research unit staff have a broad range of skills and expertise including population and fish community dynamics; bioenergetics and food web dynamics; genetics; stock assessment; statistics; fish habitat; assessment methodologies and hydroacoustics; watershed and landscape ecology; and long term monitoring.
