Ohio Dominican University's Ichthyology Class (ENV330)

Blake Mathys, Ph.D.

Summer 2019

Ohio Dominican's third Ichthyology class was held during the summer of 2019 (click here for pictures from the first class and here for the second). I would especially like to thank Brian Zimmerman and his crew for helping to make this class a success. We were able to observe 55 fish species in the wild, a new record for the course. It will be offered again in the summer of 2021.

Our first vertebrates for the course weren't fish; two buck White-tailed Deer (Odocoileus virginianus) on ODU's campus, seen on the way to our first round of seining.

A beautiful day to be in Alum Creek

Streamline Chub (Erimystax dissimilis). This is a good species to see, we've been regularly catching them in Alum Creek over the last few years.

We were able to enjoy close views of a beaver (Castor canadensis) in Alum Creek

Beaver (Castor canadensis) swimming away; we found it again later further upstream, and it actually kept us from trying to catch fish under a submerged tree stump.

Bigeye Chub (Hybopsis amblops)

One of these is a Sand Shiner (Notropis stramineus), the other is a Mimic Shiner (Notropis volucellus). Mimic Shiners were named for a reason.

Tippecanoe Darters are the second smallest fish in Ohio. This cooler contains over 200 individuals. These were part of a relocation project and were released in the Kokosing River.

The Tippecanoe Darters are each marked prior to their release.

Leaving Mad River at the end of the field portion of the course. We were able to go outside on six days and visited seven locations, giving us the best species diversity in the course's history (despite missing a few common species). I'm looking forward to doing it again in two years (and hopefully we'll have our own electrofishing equipment next time...).
