Maryland partners plant more than one billion oysters in the Bay

Restoration partners across Maryland have set a national record: for the first time, an oyster hatchery has produced more than one billion spat in a single season.

The Horn Point Laboratory Oyster Hatchery is the largest hatchery on the East Coast and raises spat, or oyster larvae, for use in research, restoration, education and aquaculture. The lab produced 634 million spat last year, but a boost in spat production is a critical step in Maryland’s plan to expand oyster populations in the Chesapeake Bay.

Habitat loss, disease and historic over-harvesting have contributed to a dramatic decline in native oyster populations. But the bivalves play a critical role in the Bay’s environment and the region’s economy, filtering water, forming aquatic reef habitat and feeding countless watershed residents.

According to a media release from the Maryland Department of Natural Resources (DNR), 60 percent of the spat produced this season went into Harris Creek. The Choptank River tributary was declared an oyster sanctuary in 2010, and is the first target of the tributary-based oyster restoration strategy set forth by Chesapeake Bay Program partners. As of this month, half of the reef construction and seed planting in the creek is complete.

The rest of the season’s spat went toward local conservation efforts, a citizen oyster growing program and aquaculture businesses and training programs.
