Now about 8 years underway there is a community effort to restore the oyster population. During the 1980s a deadly disease was introduced to the region that destroyed most of the oyster beds. The oysters were key to the health of the estuary. Great Bay had a long tradition of large populations of oysters that helped filter and clean the waters. Curious what an oyster spat is? Well, it's a baby oyster and UNH has teamed up the The Nature Conservancy and volunteer Oyster Conservationist to help repopulate this body of water with oysters. Given the varied trajectories of these environmental disturbances to marine resources, how is the collection of natural oyster spat (ten’nen saibyo) carried outIn Higashi-Matsushima, spat collection in the wild requires skilled knowledge: putting strings of flat scallop shells in the water for larvae, so that the oyster has the opportunity to settle on at the right time. He coordinates the Mobile Bay.Although a majority of our projects are completed in the Lakes Region, this past July we were able to spend a morning at the UNH Jackson Estuarine Laboratory on the shores of the Great Bay in Durham to help count oyster spats.

This positive trend is likely a result of heavy spat set, accomplished by the Auburn University Shellfish Laboratory and higher survival rate of the oysters owed to the diligent efforts of the Gardeners. 2014 saw that average rise in excess of 60 percent to 1,648. Shellfish growers will be required to use an alternative method of sourcing seed, if required. Each gardening site historically will produce 1,000 oysters for restoration. Oyster spat collection is permitted within licensed facilities, as outlined the Shellfish Aquaculture Licence under the authority of the Pacific Aquaculture Regulations. This has been determined to be the acreage needed to sustain a healthy oyster population in the Lynnhaven. Our next milestone is 152 acres of restored oyster reef. These oysters represent enough to restock nearly 12,000 m 2, or ~ 2.9 acres. About 66 acres is subtidal restored reef constructed over the past fteen years and the remaining 36 acres are constructed over natural shoreline or intertidal reef. In total, gardeners cared for 59,330 oysters which have since made their way to restoration reef sites in Mobile Bay and the Mississippi Sound. The oysters spent this time filtering hundreds of thousands gallons of water for food as they grew from an initial size of 5 mm (~ 0.2 inches) to an average of 46.1 mm (~ 1.8 inches) in 135 days. 10 caring for thousands of baby oysters (spat) in suspended gardens throughout Mobile Bay.
