Research Review 2020
Description

The Lake Erie and Inland Waters Annual Research Review took place virtually Thursday and Friday, December 17-18.

Dr. Stu Ludsin hosted the meeting with minimal technical difficulties, and we all learned about the great research taking place in Ohio. Folks from The Ohio State University, Ohio Division of Wildlife, University of Toledo, and CIGLR all presented. The presentations were supported by a variety of other schools and agencies including USGS Great Lakes Science Center, Fisheries Canada, Queen's University, Great Lakes Fishery Commission, Michigan DNR, and NOAA-GLERL. See below for the list of talks.

We extend our gratitude to all who presented!
