Ohio Dominican University's Ichthyology Class (ENV330)

Blake Mathys, Ph.D.

Summer 2023

Ohio Dominican's fifth Ichthyology class was held during the summer of 2023 (reports from the first, second, third, and fourth classes). I would like to once again thank Brian Zimmerman and his crew for helping to make this class a success. We were able to observe 60 fish species in the wild, the second highest for the history of the class. It will be offered again in the summer of 2025.
