Partnering for Mussel Restoration

Freshwater mussels and shad were once plentiful in the Delaware Estuary and its tributaries, providing a range of natural benefits to people and waterways. Today they face an uncertain future in local streams and rivers, creating a serious disadvantage when it comes to ecological health.
Now, the Academy of Natural Sciences, the College of Arts and Sciences of Drexel University, the Partnership for the Delaware Estuary, Philadelphia Water Department and Department of Parks and Recreation, Bartram’s Garden, and the Independence Seaport Museum have come together to develop the Aquatic Research and Restoration Center to coordinate large-scale restoration efforts that do not currently exist in the Philadelphia region.
The coalition will focus its efforts on continued development of programs with positive conservation impact, most notably the cultivation of freshwater mussels and shad, as part of an ecosystem restoration effort across the Delaware Estuary and its tributaries.
“This is an important step in potentially developing a wide range of research and educational opportunities throughout Pennsylvania, New Jersey and Delaware, particularly those that involve the use of freshwater mussels,” Academy President and CEO Scott Cooper said at the May 1 event where the parties signed a memorandum of understanding.
The Academy has a rich history studying freshwater mussels dating back to its founding in 1812. Today the collection contains 160,000 specimens with more than 250 named species, including some that are now extinct or highly endangered.
“These specimens “are a priceless resource for researchers working in conservation, restoration ecology and the reconstruction of historic environmental conditions in streams and rivers,” Cooper said.

Under the agreement, the coalition will:
- Propagate and raise freshwater mussels for restoration to area streams for improving water quality, habitat, and biodiversity, and for use as native “indicators” for measuring stream health and pollution. One freshwater mussel filters and cleans up to 10-20 gallons of water each day.
- Propagate and raise shad (and potentially, other fish species) for restoration to the Delaware River and area streams for improving habitat and biodiversity, as well as to provide recreational and economic opportunities.
- Provide experiential learning and laboratory research for students—from elementary through post-graduate level—that could potentially lead to careers in the sciences and engineering for students in under served communities.
