What are Local Fish Eating?

By: Sammie Alexander

As a member of the ecology team for the Potomac Environmental Research and Education Center’s (PEREC) summer OSCAR team project, my research goal is to investigate the predator-prey dynamics between fish and macroinvertebrates in two freshwater tidal Potomac River tributaries, Gunston Cove and Hunting Creek. This means, I examine the stomach content of 15 fish species known to inhabit both embayments in order to construct a food web for each location.

You would never think that drinking 16 liters of soda would be key to being an ecologist. I didn’t either. As a George Mason University senior, finishing my degree in environmental science with a concentration in marine, estuarial, and freshwater ecology, I am participating in an OSCAR undergraduate summer research project.
