Fish ecology in the Potomac watershed

by Dr. Kim de Mutsert


Every week from March to September, you can find my crew out on the water. Armed with fishnets, we’re out sampling fish in tidal embayments of the Potomac River, or tracking spawning runs of river herring in local creeks. The collections serve to document the health status of these ecosystems and populations every year, and form the basis of foodweb studies, fish community analyses, ecotoxicology research, and population models.






PTDC0209a Undergraduate students can gain similar field experience by taking the ‘Freshwater Ecosystems’ lecture course, while graduate students interested in field experience can take the ‘Estuarine and Coastal Ecology lab’ lab course.
