ANNAPOLIS, MD, October 10, 2023 — Governor Wes Moore today announced that more than 1.7 billion new juvenile oysters have been planted on sanctuary and public oyster fishery sites in Maryland’s Chesapeake Bay this year, surpassing an ambitious 2023 planting goal and setting a new annual record. The milestone means that the state has planted almost 7 billion oysters since launching its large-scale oyster restoration strategy in 2014 with the help of numerous partners.
“Planting 1.7 billion oysters this year shows the success of the broad partnership of watermen, scientists, academics, nonprofits, and state and federal government officials dedicated to this vital natural resource and economic driver for Maryland,” said Gov. Moore. “I’d like to thank the partner organizations and our dedicated Department of Natural Resources staff who enabled the state to achieve this significant accomplishment.”

In 2014, Maryland committed to restoring oyster populations in five Bay tributaries, as part of the interstate Chesapeake Bay Watershed Agreement. The state embraced oyster plantings as a key component of its Chesapeake Bay restoration and replenishment strategy by deploying hundreds of millions of juvenile oysters on both sanctuary reefs and public oyster reefs annually. Oysters are beneficial because they filter excess nutrient pollutants from the bay, provide valuable habitat for other marine species, and boost the state’s commercial seafood industry through annual harvests and oyster aquaculture.
“In recent years, we’ve seen several good natural spat sets for oysters, which have boosted the bivalves’ overall population as well as economic returns for harvesters and growers,” said Maryland Department of Natural Resources Secretary Josh Kurtz. “Oyster planting efforts have enabled us to work toward a broader goal to increase the species’ population in Maryland for their ecological benefits.”
“It took three decades to plant 10 billion oysters in Maryland, and half of that was completed in the last decade,” said Oyster Recovery Partnership Executive Director Ward Slacum. “To achieve meaningful results for the Chesapeake Bay, we must be unyielding and this year’s planting rate is a positive sign that Maryland is committed to Bay restoration.”
Oysters for the five-large scale restoration tributaries are grown primarily at the University of Maryland Center for Environmental Science’s Horn Point Laboratory in Cambridge. Large-scale restoration projects are completed in partnership with the Maryland Department of Natural Resources, National Oceanic and Atmospheric Administration, Oyster Recovery Partnership, and the U.S. Army Corps of Engineers.
In 2023, the state also worked with several other partners to raise oysters for planting in sanctuaries, private leases, and on public oyster harvest grounds. These include the public participants in Marylanders Grow Oysters and Oyster Gardening initiatives, Chesapeake Bay Foundation, County Oyster Committees, Severn River Association, ShoreRivers, numerous other river associations, the St. Mary’s County Watermen’s Association, and several private spat producers.
Of the 1.7 billion oysters planted so far this year, 1.03 billion were planted in oyster sanctuaries targeted by the state for large-scale restoration; 112.61 million were planted in smaller sanctuaries in Anne Arundel and Queen Anne’s County; 212.4 million were planted in the Eastern Bay region sanctuaries for the Department of Natural Resource’s Eastern Bay Project; and 455.25 million have been planted on public oyster grounds throughout the state.
“Our scientists have been working hard to optimize the production of oysters at our Horn Point hatchery, and it’s paying off. Working with our partners in this effort, combined with good weather and good water quality, this record level of oyster production is being realized,” said University of Maryland Center for Environmental Science Interim President Bill Dennison. “We continue to use good science to understand oyster biology and ecology to support restoration of this key species in the Chesapeake Bay.”
