Oysters as Nitrogen Bioextractors
Oysters filter particles that contain nitrogen (and carbon) from the water. Wild oysters cycle small amounts of that nitrogen back into the environment, however farmed oysters, once harvested from the estuary, directly remove the nitrogen from the aquatic ecosystem. A recent paper, which NHAES scientists contributed to, states that a combination of oyster aquaculture and reef restoration will complement land-based efforts to reduce nitrogen flowing into the Great Bay estuary.
