Ohio Dominican University's Ichthyology Class (ENV330)

Blake Mathys, Ph.D.

Summer 2021

Ohio Dominican's fourth Ichthyology class was held during the summer of 2021 (click here for pictures from the first class, here for the second, and here for the third). I would especially like to thank Brian Zimmerman and his crew for helping to make this class a success. We were able to observe 61 fish species in the wild, a new record for the course. It will be offered again in the summer of 2023.
