Stakes, were deployed at three sites in Melville Water in the Swan-Canning Estuary Habitats, each comprising translocated M. Similar suite of ecosystem services to oysters. Mediterranean Mussel Mytilus galloprovincialis is gaining popularity and provides a While oysters have traditionally been used as a candidate species, the There has recently been a concerted effort to restore shellfish reefs, particularly inĪustralia. Due to the ecosystem services provided by these biogenic habitats, Result of anthropogenic activities to the point where such reefs are functionally extinct Large extents of shellfish reefs have become degraded around the world as a Analogous information should underlie restoration planning for other biogenic habitats like seagrass meadows and coral reefs. Although our results may not apply to areas with less natural oyster recruitment, our study highlights the need to quantify basic ecological processes on appropriate spatiotemporal scales to optimize restoration actions. Financial resources used for oyster seed would be better used to increase the amount of substrate for oyster settlement. Our findings, in combination with information from 3 additional sanctuaries seeded in 20, indicate that seeding does not enhance oyster reef restoration efforts in Pamlico Sound. Although oyster settlement varied spatially, natural recruitment swamped any measurable effect of seeding. We experimentally manipulated marl mounds at 3 sanctuaries differing abiotically and biotically during summer 2010 and varied recycled shell and seed presence, seed size, and shell and seed deployment date. ![]() North Carolina, USA, has established subtidal oyster sanctuaries in Pamlico Sound using marl mounds and hatchery-raised juvenile oysters set on recycled shell. These costly setting efforts are carried out despite limited information on whether seed oysters accelerate reef development and, if so, how oyster size and time of deployment maximize oyster survival. If oyster recruitment is thought to be limited, hatchery-raised juvenile oysters are set on the hard substrate. Restoration primarily consists of deploying hard substrate. To reverse the current oyster reef declines, governmental and private organizations have invested substantial resources into oyster restoration. Oyster reefs are one of the most depleted and degraded marine habitats worldwide.
