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

Principal Investigator: 

Matthew P. Hare

Start/End Year: 

2003 to 2007

Institution: 

University of Maryland, College Park, Department of Biology

Co-Principal investigator:

Topic(s): 

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.
