Chesapeake Bay oyster industry focuses on hatchery research and shell recycling

Efforts to support oyster aquaculture and restoration in the Chesapeake Bay are focusing on both biological research and community-led recycling initiatives.

A research project led by the University of Maryland Center for Environmental Science and Morgan State University aims to investigate the causes of oyster hatchery crashes. These unpredictable larval mortality events impact both commercial aquaculture and restoration efforts. Researchers will use DNA sequencing and water quality monitoring at the Horn Point Oyster Hatchery and the Patuxent Environmental & Aquatic Research Laboratory to identify chemical, microbial, or viral triggers, such as Vibrio bacteria or specific dinoflagellates.

Simultaneously, the Oyster Recovery Partnership is managing a large-scale shell recycling network to provide the hard surfaces necessary for young oysters to grow. While the state requires approximately 2 million bushels of shell annually to replenish fishery grounds and support aquaculture, the program recovered 25,618 bushels in 2023. Residents in Anne Arundel County can contribute to these restoration efforts by dropping off shells at various public collection sites and recycling centers.
