While concentration shifts of each Vibrio species were apparent post-storm, statistical tests indicated no significant change in concentration change for either Vibrio species by location (surface or near bottom oysters) or date sampled (oyster tissue, surface water and sediment concentrations). and associated virulence genes were measured in oysters with a combination of real-time PCR and most probable number enrichment methods, and in sediment and surface water with real-time PCR. Aquacultured oysters were sampled from two levels in the water column: surface 0.3 m and near-bottom just above the sediment. To determine if a storm event (i.e., high winds, large volumes of precipitation) could alter concentrations of Vibrio vulnificus and Vibrio parahaemolyticus in aquacultured oysters (Crassostrea virginica) and associated surface water and sediment, this study followed a sampling timeline before and after Hurricane Irene impacted the Chesapeake Bay estuary in late August 2011. To ensure the successful proliferation of C. ![]() Despite the expansion, further development of designated reef area is necessary To the state of health in which they once were. Is the hope of many Delaware residents that the reintegration of oysters into the Inland Bays will help to return their bays ![]() Although the oyster gardening program in Delaware is relatively new, its popularity has grown tremendously. Gardening’ to help restore the oyster population, while instilling within the community a strong sense of stewardship for Many conservation organizations in the area have developed community-involvement programs commonly referred to as ‘oyster Has plummeted as a result of overharvesting, extreme eutrophication, and disease. However, with the ever-increasing development along our coastlines, the oyster population throughout the Mid-Atlantic region They clean the water by filtering out suspended particulates from the waterĬolumn, while their reefs serve as valuable habitat for many ecologically and economically important macrofaunal species.

Funding support for the program has come from state funds, Virginia’s Center for Innovative Technology, NOAA’sNational Coastal Resources Research and Development Institute and the National Marine Fisheries Service. Armistead,Williams first pointed us in the right direction and Linwood Holton, former governor of Virginia and President of Virginia’s Center for Innovative Technology (CIT), provided not only the financial support of his agency, but needed encouragement,and enthusiasm for our program,over the years. Donelson Wright have allowed the program,to continue. Administrative support under the VIMS Dean and Director Frank O. Mike Castagna con- ceived of and initiated the program. Acknowledgments The ideas expressed here are the product of work conducted by the staff of the Virginia Institute of Marine Science Aquaculture Program, largely since 1989.
