Genetic rehabilitation and conservation of Chesapeake oysters using disease-resistant oyster strains: a study of their recruitment and introgression potential

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.

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.
