VIMS researchers will evaluate the health of triploid C. ariakensis and triploid, P. marinus and H. nelsoni- tolerant C. virginica at the time of deployment and then again seasonally through the end of the Virginia Seafood Council (VSC) trial. Relative disease pressure in these species will be obtained by determining the prevalence and intensity of Perkinsus marinus (Dermo disease), Haplosporidium nelsoni, (MSX disease), and Bonamia infections, and of shell infestation by the boring worm Polydora. Additionally, on the chance that a minor native oyster parasite may emerge as a major pathogen in C. ariakensis, the researchers will monitor both species for the numerous other diseases that occur in C. virginica in our region. These minor diseases normally have no serious impact on the health of C. virginica and pose no threat whatsoever to consumers. Thirty oysters will be collected from each of the grow-out sites during each of the sampling periods.
Partnership with the Oyster Disease Research Program (ODRP)
ODRP has funded a project called "Shell disease of C. virginica and C. ariakensis: A Marketing issue" by R. Fisher, J. Shields and H. Kator of VIMS. The goal of the project is to evaluate the potential impact of shell disease on aquaculture of non-native and native oysters. The overall objectives are to identify the causitive agents of shell disease discovered in both C. virginica and C. ariakensis during the VSC field trials, assess the impact of the syndrome on oyster health, determine the possible affects on the market, and identify disease transmission and possible methods of control. Twenty five oysters will be collected from each of the grow-out sites during the sampling periods.
