• Understanding our wild oyster populations (Alphin, Finelli, Kamel, Leonard, Loh, Mallin, Posey, Varney, Volety, Wilbur)• Oyster distribution, growth, survival, and
recruitment• Role of disease • Interactions with other plants and animals,
including predation• Key factors that determine the resilience of
our wild oyster populations

Shellfish Research• Understanding the ecosystem impacts
of oysters and oyster restoration (Alphin, Eulie, Jarvis, Leonard, Mallin, Posey, Wilbur)
• Critical ecosystems services important to our local economies• Fisheries
• Habitat for commercially important species such as blue crabs
• Improve water quality
• Shoreline protection

Shellfish Research• Shellfish Mariculture (Alphin, Darrow, Jarvis,
Posey, Varney, Volety, Wilbur)
• Oyster lease siting tool• GIS based tool that compiles numerous existing data sets
to allow potential growers to virtually examine areas that may be appropriate for new mariculture operations http://uncw.edu/benthic/sitingtool/

• Impacts in the field• NERR Science Collaborative Project
• Examining impacts of commercial oyster farming on water quality and on adjacent fauna, including wild shellfish populations resources
• Evaluating maximum farm capacity in an area
• Seagrass communities
