The Waterfront Partnership and Chesapeake Bay Foundation on Wednesday announced an expanded oyster program for Baltimore’s harbor. The program, which now will be called The Great Baltimore Oyster Partnership after launching last year as the Healthy Harbor Oyster Partnership, plans to grow 165,000 baby oysters in the harbor. That’s more than triple the approximately 50,000 grown in the first year and planted on the reef at Fort Carroll. Brown Advisory, BGE/Constellation, Legg Mason and T.Rowe Price will return as sponsors and provide volunteers, joined by engineering, architectural and planning firm Whitman, Requardt & Associates. Volunteers will tend to oyster gardens around the harbor starting later this month, to be planted near Fort Carroll in the spring. The program also will ask the public to sponsor and tend to oyster cages with the help of the Downtown Sailing Center and Baltimore Marine Centers.
