Examining the Ecological Physiology of Oysters on a Reef Habitat: Interactions of Dissolved Oxygen and Disease Dynamics

Description:
Construct 24 mound oyster shell reefs planted with hatchery-produced spat on or near the Flag Pond oyster bar. Monitor water quality in and around the reef habitats, characterize differences between water qualities at the different depths. Sample oysters to determine relationships between anoxia, P. marinus prevalence and weighted prevalence (intensity), and physiological state of the oysters. Measure the physiological response of oysters to hypoxia in the benthos using real-time water quality measurement and diver sampling during the episode(s). Correlate physiological changes in the oysters with position on the reef habitat, depth, and disease acquisition and progression.

Developing a habitat model for mysids, an important link in Chesapeake Bay food webs
Mysids are important mesozooplankton prey for many species of fish in Chesapeake Bay and are an important link in transferring energy from lower to upper trophic levels. Mysids also serve as biological vectors for benthic-pelagic coupling due to their diel vertical migration and omnivorous prey-switching behavior, which makes mysids important regulators of food web architecture. Despite their central role in coastal food webs, surprisingly little is known about mysid ecology and dynamics in Chesapeake Bay.
