Local fishermen are building oyster reefs in Pamlico Sound

Several local commercial fishermen began distributing 3,000 bushels of oyster shells in Pamlico Sound behind Ocracoke on Tuesday, Aug. 3, to build habitat and supplement their income.

The N.C. Division of Marine Fisheries will pay the fishermen $2 a bushel to distribute the shells as part of the N.C. Coastal Federation’s $5 million federal economic recovery grant. The grant also included building two large oyster reefs covering 48 acres in Pamlico Sound. That work was completed in May. The project has so far created about 135 jobs.

During the summer, oyster shells and rock, called cultch, can be put into the water, to provide habitat for oyster larvae. For the first two weeks of their lives, oysters are carried about by currents. Then, oysters sink to the bottom and attach to clean, hard surfaces in order to survive. That’s why oysters are found growing attached to one another in reefs, on bridge pilings, or on other hard underwater surfaces.

The cultch isn’t beneficial only to oysters. It also provides habitat and protection for juvenile fish, crabs, small marine organisms, and many important commercial and recreational species. As the oyster reefs develop, larger fish tend to congregate around them, feeding on the smaller fish and marine life. The reefs are important nurseries and feeding grounds that help support North Carolina’s billion dollar commercial and recreational fishing industries.

The fisheries division typically uses large barges to transport the cultch to planting sites. With this project, the fisherman, using smaller boats, can distribute the shells in water too shallow for the barges.

Through an application process, the division selected 72 fishermen statewide to participate in the cultch-planting project.

They will distribute 41,000 bushels of oyster shells between May and August in different coastal waters of the state. The sites in Hyde, Carteret, Onslow and New Hanover counties combine for more than 10 acres of created oyster habitat.

To date 30,000 bushels of shell have been deployed. The sites will be closed to harvest for four years in order for the oysters to grow and provide habitat, but hook-and-line fishing will be allowed.

The division will monitor the oyster restoration sites in Pamlico Sound to evaluate the development of the reefs. Then the sites will be opened to harvest and future plantings, providing additional income for fishermen.
The N.C. Center for the Advancement of Teaching and the National Park Service are supporting the project by stockpiling the shells at their Ocracoke facilities, and James Barrie Gaskill, an Ocracoke commercial fisherman and federation board member, is providing a loading area for the fishermen.
