FY2005 Task 9.21
Virginia Marine Resource Commission
Seaside Heritage Program - Oyster Reef Restoration
Project Description as Proposed:
Oyster reefs will be constructed in association with eelgrass restoration projects. Reef restoration and eelgrass planting efforts have been very encouraging for the past 5 years, especially, in the Cobb Island and South Bay areas of Northampton County. For FY 05 reefs will be constructed in South Bay, behind Wreck Island.
Reefs will be constructed from shells that have been harvested from local fossil shell deposits or from conch shells from shucking houses. Because of the shallow water of the Seaside Bays, small shell harvesting and reef construction equipment will be used. Reefs average 1,000 to 4,000 bushels each, vary from 200 to 800 square feet of footprint, and are approximately 1 to 1.5 feet tall. Shell costs vary from $1.00 to $1.50 per bushel to construct the reefs. At completion of this project, 12 to 25 new oyster reefs will have been constructed. All reef building activity will occur between May and July, 2006. Reefs will be monitored for spatset in the Fall of 2006.

Project Summary Provided by Grantee:
Oyster reefs were constructed in the Brockenberry area near Oyster, Northampton County, during April 2006. Reefs were constructed on Public Ground # 17 at approximately 37º 17' 35', 75º 45' 49'. Conch shells were loaded and transported from a processing plant to Oyster Harbor, then loaded onto small barges and transported to the construction site. A total of 29, 400 bushels of conch shells were deployed onto 3 areas for a total of 0.93 acres. The cost of the conch shells was $1.655/bushel for a total of $48,657.00. In May, an additional 1,200 bushels of dredged oyster shells were added to one area to complete the project ($1.20/bushels = $1,340.00). Spatset was monitored in late November. All 3 small reefs received a very high spatset. South Area - 3,308 spat/meter. North Area - 2,952 spat/meter. Marsh Area - 1,756 spat/meter
"No Harvest" signs were placed on the 3 newly constructed areas.
