Oyster Habitat Restoration Projects
A key task in restoring the Chesapeake Bay's oyster population is finding appropriate locations to plant oyster spat and place materials on which spat will grow. Oyster will grow on almost any stationary hard surface (substrate) and in a variety of aquatic environments. However, a commercially sustainable oyster population requires optimal growing conditions, including appropriate growing surfaces, suitable water quality and low sedimentation rates.
Discovery of bay bottom conditions using traditional methods requires expensive and time-consuming sampling programs or visual inspection using divers or cameras. However, recent developments in remote-sensing technology have made mapping bay bottom characteristics more efficient and less costly. Onboard DNR's R/V Kerhin, Maryland Geological Survey has the capability to map the bay bottom and subsurface geology using acoustic remote sensing systems. These systems include:
and Estuarine Geology program participates in several oyster
restoration projects around the Chesapeake Bay, including the Poplar
Island Environmental Restoration Project and the Oyster
Bed Mapping Project. This
work will lead to a more thorough understanding of bay bottom
conditions and how they affect the
and health of oyster populations in tidewater Maryland.
