Education, Research and Technical Assistance for Managing Our Natural Resources

Understanding demographic and population structure is important for informing management, but little research has been conducted on this topic in the Mississippi River. This project will use three techniques, genetics, otolith microchemistry, and age/growth estimation to understand structure in multiple species within the Upper Mississippi River. The project is a collaboration between USGS, the Wisconsin Department of Natural Resources, and multiple universities including Southern Illinois. The data from this will be vital for developing new management strategies for this in this region.
