Mussel Survey

In late September, Academy staff scientists and collaborators conducted a mussel survey on the Schuylkill River upstream from Boathouse Row.

Their goal was to document the presence or absence of mussels and, in particular, whether there were any Tidewater Mucket (Leptodea ochracea) in this stretch of the river. This survey was the last in a series that was conducted throughout the lower Delaware River watershed.

Searching the shallow regions by hand, the scientists were able to find several dozen mussels of 2-3 species, but alas, no Tidewater Mucket.

This information will be added to the data collected at the earlier sites to provide more detailed information on the numbers and density of Tidewater Mucket, and other mussel species, within the mainstem lower Delaware and Schuylkill rivers.
