Description:
The overall project objective is to determine the transmission dynamics of P. marinus in low salinity areas in order to develop disease avoidance strategies and to promote wise and effective restoration of oyster populations in low salinity regions of Chesapeake Bay. Specifically we propose to: ( 1) optimize highly sensitive and quantitative PCR diagnostic techniques for the detection and enumeration of water-borne stages of P. marinus from water column samples (2) determine the abundance of water-borne P. marinus cells at four sites located in low salinity areas (9-14 ppt) of three Chesapeake Bay tributaries, the Choptank, Patuxent, and James Rivers, using highly sensitive, specific, and quantitative PCR techniques and (3) determine relative P. marinus infection rates at the same four low salinity sites by monitoring infection acquisition in uninfected sentinel oysters deployed at each site.

Exploring the Use of Benthic Microbial Fuel Cells to Remove Sulfide While Harvesting Energy from Oyster Aquaculture Biodeposits
Oyster aquaculture is a rapidly growing industry in Maryland’s Chesapeake waters which stimulates economic activity and may provide a host of ecosystem benefits. A potential concern associated with the intensification of the oyster aquaculture is the local production and accumulation of oyster biodeposits, which can lead to a porewater sulfide accumulation and declining bioturbation, symptoms of declining ecosystem function. Sulfide is naturally removed from the seafloor by the interactions between bioturbating infauna and sulfide oxidizing bacteria.
