Recycled Oyster Shells and ‘Oyster Castles’ Create Living Shoreline Protection Along Delaware Bay

Read the full story from Rutgers University.

Using recycled oyster and clam shells, a Rutgers University team partnered with The Nature Conservancy, The Partnership for the Delaware Estuary and the U.S. Fish and Wildlife Service to create a living artificial reef along Delaware Bay to protect the shoreline from storm damage.

These oyster castles – essentially modified concrete blocks that become living reefs as oyster larvae attach to them and grow – can reduce the impacts of future storms, provide habitat for wildlife and improve water quality.

Creating a living shoreline with wetland plants, natural structures and shellfish breakwaters to absorb wave energy and reduce erosion can help protect coastal areas from regular flooding and storm damage.
