![]() But even with a growing oyster aquaculture industry in Barnegat Bay, it still wouldn’t be enough to create our “forest.” For our work, we resort to a method called remote setting.Ĭages of shells in tanks at Parson’s Mariculture in Little Egg Harbor (C. ![]() For some places like Delaware Bay or the Gulf of Mexico, this strategy works. We could just dump a lot of shell into the bay and hope to catch any larvae that could settle onto them. To build an oyster reef, we need to provide substrate for the oyster larvae to adhere to. Random concrete blocks or pilings to settle onto. Huge abundance of oyster shells in the bay, oyster larvae are left to find Oyster, that means a hard surface or preferably another oyster shell. Into an adult, it first needs to find a suitable place to settle. That disperses with the currents for a few weeks. Oysters have a complex life cycle with a microscopic larval stage To really bring oysters back to the bay, we need to bring back the oyster reefs. It won’t provide any habitat or protection for other animals. It’s like having an evergreen forest with only a half dozen trees. This doesn’t mean they are extinct or even endangered, it just means that they don’t exist in the ecosystem role they were meant to play. In Barnegat Bay, the eastern oyster is functionally extinct. Christine Thompson, Assistant Professor of Marine Science, Stockton University Recipe for an oyster reefĪ lot of shell. Oyster spat growing on a recycled oyster shell (S. Educate volunteers and the general public about the ecology and value of a healthy population of Inland Bays oysters.By Karen Walzer, 07/26/19 Share Facebook Twitter. ![]() Create habitat for other marine species which are the base of the food chain for fish, crabs and other species.Protect young spat, giving them a chance to grow through better conditions.Improve water quality through various restoration efforts.Research on oysters and prove that oysters can grow great anywhere in our Inland Bays.Oyster Gardening oysters are not grown for food and are NOT SUITABLE for human consumption. Gardeners will be in possession of the oysters for one year, when the Center will remove them and place them in various restoration or research projects throughout the Bays. During early summer, trays of oyster shell with fingernail-sized spat are then distributed throughout the Inland Bays to the gardeners for grow-out in their baskets. In the hatchery, a million or more microscopic oyster larvae are exposed to spent oyster shell to imitate the natural “setting” process. Oyster larvae used in the program are hatchery-produced at the Rutgers University Haskin Shellfish Research Laboratory, using broodstock lines bred for resistance to MSX and Dermo disease. Each gardener is responsible for one site, and each site grows approximately one-hundred oysters, using spat stocks and gear provided by the Center. The Oyster Gardening program employs volunteer gardeners to care for small “spat,” growing them to adult size by practicing basic husbandry techniques. The program is a cooperative effort between the Center, the Sea Grant Marine Advisory Program, and volunteers throughout the Inland Bays watershed! The program brings together scientists and volunteers in an effort to restore the American Oyster ( Crassostrea virginica) to the waters of Delaware’s Inland Bays. ![]() The program began in 2003 through a generous grant from the National Fish & Wildlife Foundation’s Five-star Restoration Challenge Grant Program. The Center provides juvenile oysters and gear to raise them the “gardeners” provide basic husbandry and grow them for about one year, when they will then be used in restoration projects. The Center’s Oyster Gardening program is a restoration project that employs waterfront property owners to raise small amounts of oysters in the waters that surround their docks and bulkheads. ![]()
