Description:
The objectives of this project wiIl be to deploy hatchery produced seed on a 5 to7 acre portion of a newly constructed shell bar in three Oyster Recovery Areas (ORAS) and monitor those seed to determine how well they survive and how quickly they become infected with P. marinus and die. The specific objectives are as follows: Deploy seed produced from remote setting sites (see other, related proposal by Meritt) on bars in oyster recovery areas (Chester, Choptank and Nanticoke Rivers), Deploy natural seed on a bar in the Nanticoke River to compare it to hatchery plantings, Monitor seed at all sites for growth, mortality, density and disease monthly except during January and February, Monitor changes in the benthic faunal communities on both seeded grounds and shell-only grounds to determine the impact of oysters on the bottom habitat as compared to shell only bottom.

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.
