A Look at Chesapeake Bay Oyster Restoration

November 01, 2021

It has been a busy year for oyster restoration around the Chesapeake Bay. Here are some snapshots of the restoration process.

Spat on shell—juvenile oysters—are grown at the University of Maryland Center for Environmental Science’s Horn Point Hatchery. Spat are the small shells in this photo that are attached to the bigger shells. There are a handful of spat on each larger shell in this picture. They are created when oyster larvae settle on hard substrate, like these recycled oyster shells. They then grow into oysters, including growing their own shells that are still attached to the original larger shell. This process is how oyster reefs grow. Photo: Horn Point Lab Hatchery
