Research Review 2021

Lake Erie-Inland Waters Annual Research Review Title Slide

We were honored to once again host an in-person (and online) Lake Erie and Inland Waters Annual Research Review December 9 and 10 at the Nationwide & Ohio Farm Bureau 4-H Center. This event is an opportunity to bring together the researchers from Ohio Division of Wildlife and the university scientists and graduate students with whom they collaborate to study fisheries science and aquatic ecosystems across Ohio.

Welcoming remarks were delivered by Susan Olesik, Dean of the Division of Natural and Mathematical Sciences in the College of Arts and Sciences at The Ohio State University, and by Kendra Wecker, Chief of the Division of Wildlife in the Ohio Department of Natural Resources. Closing remarks were offered by Scott Hale, Executive Administrator of Fish Management and Research at the Division of Wildlife in the Ohio Department of Natural Resources.

Talks ranged from zooplankton, to catfish, to walleye, to sturgeon. See below for a list of talks and posters, and reach out to if you would like copies of the slides or posters. Most talks were given in person, with just a few given as pre-recorded talks with the authors available for questions on Zoom after. There were more than 50 individuals participating via Zoom, including asking questions to in-person presenters.
