Description:
Several concrete objectives will be met by capitalizing on the ground work achieved with previous Sea Grant funding. The two years of funding requested here will allow (1 ) estimation of recruitment distance distributions around focal reefs planted with disease-tolerant DEBY strain oysters, (2) quantification of rates of interbreeding between DEBY strain oysters and wild background oysters, informing an analysis of introgression of genetic factors contributing to disease tolerance, and (3) quantification of inbreeding in DEBY strain broodstock as well as an analysis of the inbreeding effects of standard hatchery amplification for supplementation.

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.
