2004 Chesapeake Bay Oyster Management Plan
Available: Yes Publication Date: 12/05/2005 Data Type: report
The Oyster Management Plan includes both a general framework and specific guidance for managing and rebuilding the native oyster stock in Chesapeake Bay. The development of the plan was a multi-partner endeavor by representatives from state and federal agencies, academia, environmental organizations, and the oyster industry. The strategies include evaluating the use of sanctuaries and harvest reserves to obtain optimum ecological and economic benefits; rebounding habitat; increasing hatchery production; breeding disease-resistant oysters; evaluating impediments to aquaculture; managing harvest; improving coordination among the oyster partners; and developing a database to track oyster restoration projects and monitor results.

Assessing a Ten-Fold Increase in the Chesapeake Bay Native Oyster Population (2 MB)
Available: Yes Publication Date: 04/01/2005 Data Type: report
AVAILABLE ELECTRONICALLY ONLY. The Chesapeake Bay Environmental Model Package (CBEMP) was used to assess the environmental benefits of a ten-fold increase in native oysters in Chesapeake Bay. The CBEMP consists of a coupled system of models including a three-dimensional hydrodynamic model, a three-dimensional eutrophication model, and a sediment diagenesis model. The existing CBEMP benthos submodel was modified to specifically represent the Virginia oyster, Crassostrea virginica. The ten-fold oyster restoration is computed to increase summer-average, bottom, dissolved oxygen in the deep waters of the bay (depth > 12.9 m) by 0.25 g m-3. Summer-average system-wide surface chlorophyll declines by 1 mg m-3. Filtration of phytoplankton from the water column produces net removal of 30,000 kg d-1 nitrogen through sediment denitrification and sediment retention. A significant benefit of oyster restoration is enhancement of submerged aquatic vegetation. Calculated summer-average biomass improves by 25% for a ten-fold increase in oyster biomass. Oyster restoration is most beneficial in shallow regions with limited exchange rather than in regions of great depth, large volume and spatial extent.

Ecosystem Effects of Oyster Restoration in Virginia Habitat and Lease Areas (1 MB)
Available: Yes Publication Date: 06/01/2006 Data Type: report
This report is the third in a series in which the Chesapeake Bay Environment Model Package was used to assess the environmental benefits of oyster restoration in the Chesapeake Bay. Here, the effects of oyster restoration to all potential Virginia oyster habitat were investigated.

Non-native Oysters and the Chesapeake Bay (204 KB)
Available: Yes Publication Date: 08/14/2003 Data Type: fact sheet
While Chesapeake Bay Program partners continue their work to restore native oysters, efforts are also underway to better understand the risks and benefits surrounding the possible introduction of non-native oysters into the Bay. This backgrounder provides a brief history of the study of non-native oysters in the Chesapeake Bay watershed and the debate surrounding the issue.

Statement on the Release of the National Research Council Report on Non-native Oysters and the Chesapeake Bay
Available: Yes Publication Date: 08/14/2003 Data Type: press release
In this statement, the Chesapeake Bay Program addresses the National Research Council’s study “Non-Native Oysters in the Chesapeake Bay.” The Bay Program announces that it will set up an ad-hoc committee to thoroughly review the study’s findings and recommendations. According to Bay Program scientists, the study will serve as the basis for both near- and long-term management strategies affecting the future of non-native oysters in Chesapeake Bay. Its findings will guide new research, establish risk assessment needs and form a significant component of a planned Environmental Impact Statement regarding the possible introduction of the Suminoe oyster.

Recommendations on Suminoe Oyster (Crassostrea Ariakensis) Aquaculture in Chesapeake Bay (183 KB)
Available: Yes Publication Date: 04/23/2002 Data Type: fact sheet
The purpose of this document is to communicate the findings and recommendations of the Federal Agencies Committee of the Chesapeake Bay Program with respect to an anticipated proposal to introduce the Suminoe oyster into the waters of the Chesapeake Bay for aquaculture production. The Federal agencies of the Chesapeake Bay Program (acting through the Administrator of the Environmental Protection Agency) are signatories to the Chesapeake 2000 agreement and expect that the other Chesapeake Bay Program partners will consider these recommendations in their review of any such proposal.
