Disease, habitat loss, overharvesting, and poor water quality have left the Chesapeake Bay’s iconic wild oysters in a dismal state, at just 0.3 percent of their teeming population in the early 1800s, according to a 2011 research study by the University of Maryland Center for Environmental Studies.

Increasing the Chesapeake’s oyster populations is a high priority in Maryland. That is because of the creatures’ ability to filter vast amounts of water, improving its quality. And oyster reefs provide habitats for a variety of other fish, benefitting the entire ecosystem.

However, restoring self-sustaining populations of wild oysters to a significant level may prove difficult because of a host of ecological, economic, and cultural hurdles. For example, generations of Chesapeake watermen have harvested wild oysters from grounds scattered around the Bay. Encouraging the remaining watermen to embrace aquaculture — oyster farming at fixed locations — is a challenging proposition because this business requires a different set of skills and substantial start-up costs.

There are no easy fixes to these challenges. Maryland Sea Grant Extension plays an important role in promoting progress in collaboration with federal and state agencies, other university programs, and non-governmental organizations. Our key efforts are listed below. Oyster Hatchery

Donald Meritt, a Maryland Sea Grant Extension aquaculture specialist, works in cooperation with many partners to operate the Horn Point Oyster Hatchery, which cultivates young oysters for aquaculture and restoration projects. In 2012, the hatchery produced more than 880 million oyster spat (young oysters that are attached to a larger oyster shell), a record. The hatchery works with its partners to distribute oysters for commercial aquaculture and to build up oyster reefs in the Bay.

Maryland Sea Grant Extension helps individuals and companies obtain financing and technical know-how to start aquaculture businesses in the Bay. An Extension specialist helps entrepreneurs to apply for low-interest loans from the state of Maryland. This program is targeted for watermen who want to transition from harvesting wild oysters to growing them through aquaculture; the money helps them to buy equipment.

Maryland Sea Grant Extension also offers oyster hatchery short courses for those interested in working in a hatchery or in starting their own hatchery. Here’s a photo gallery of a recent short course. In addition, Extension sponsors day-long shellfish conferences with other partners to provide detailed up-to-date information about starting and running an aquaculture business. Brochures and highlights from past conferences are included below. To find out about future courses and conferences, contact Eastern Shore Agent Don Webster. Advising Policy Makers about Aquaculture

Maryland Sea Grant Extension Eastern Shore Agent Don Webster has played a vital role in working to promote major changes in state policies that allowed significant expansion of shellfish aquaculture throughout the Chesapeake Bay. The legislation expanded the area of the Chesapeake Bay that can be leased for oyster harvesting and the categories of eligible lease holders. Learn more. Oyster Gardening

Read about local programs in oyster gardening. That’s where volunteers grow young oysters in cages suspended off docks and later donate them for use in oyster-reef restoration. Jackie Takacs, an Extension watershed specialist, assists with oyster gardening projects in Southern Maryland. For More Information

• Shellfish Aquaculture Development in Maryland and Virginia: Economy, Employment, Environment. This 2009 report produced by the Sea Grant programs of Maryland and Virginia and commissioned by the NOAA Chesapeake Bay Office details the history of shellfish aquaculture in the Bay and sets out current opportunities and challenges.

• Maryland Oyster Aquaculture History & Policy: Background Documents Prepared for the Maryland Oyster Advisory Commission. These are a series of documents prepared by Extension agent Don Webster for the Maryland Oyster Advisory Commission about the past and future of oyster aquaculture in Maryland. The reports identify problems facing the industry during the past three decades as well as potential solutions for rebuilding a profitable and ecologically beneficial oyster industry.

• Native Oyster Restoration in Maryland and Virginia: An Evaluation of Lessons Learned 1990-2007 — A Preliminary Report. Insufficient data exist to show whether oyster-restoration efforts in the Bay have resulted in increasing numbers of oysters, according to a review by a scientific panel and summarized in this report. Their summary recommends improvements in data collection and the coordination of restoration efforts.

• Oyster Restoration Workgroup. This group studies how to promote and measure the success of shellfish restoration projects. How to measure success or failure is a key question about which little consensus exists among experts. The group’s website promotes a forum for these discussions, professional networking, and a repository of links to the latest literature, including suggested approaches for measuring restoration success based on a suite of agreed upon goals and associated metrics. The workgroup’s focus includes intertidal and subtidal oyster reefs. Sponsors include several academic and nonprofit organizations.

• Who Killed Crassostrea virginica — The Fall & Rise of Chesapeake Bay Oysters. (One-hour documentary.) The Chesapeake was once home to the richest oyster grounds in the world. Who killed the Bay’s native oysters? This award-winning, hour-long documentary sets out to answer that question. The film details both the poignant destruction of a fabled fishery and the prolonged scientific inquiry into the origins of a killer parasite. Purchase the DVD from our Bookstore.
