Description:
We propose to examine how dissolved oxygen concentrations and the spatial patterning of dissolved oxygen, water temperature and predation and prey abundances interact to affect the consumption, growth, production and recruitment of important fishes in the Chesapeake Bay. Research will focus on key piscivores (striped bass, bluefish, weakfish) and planktivores (Atlantic menhaden, bay anchovy). Spatially-explicit models will be used to compare patterns of growth and consumption relative to changes in habitat structure, prey abundances and spatial heterogeneity in the environment. Model simulations will address specific management questions dealing with the interrelationships of fish production and water quality.

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.
