Oysters are remarkable. They are a popular seafood. At NOAA, we support research and policy development to grow sustainable aquaculture in the United States.
Oysters also provide many benefits to the ecosystem the live in. They are filter feeders—they clean the water as they eat. And they grow in reefs, which provide great habitat for many other species. But in many places, their population has plummeted. So we also work to restore oyster reefs.
Let's learn more about oysters!
Some oyster species are native to the United States, while others have been introduced to support shellfish farming.
- The Eastern oyster is the only native oyster on the East Coast of North America. It is found from the Gulf of St. Lawrence around to the Gulf of Mexico, including the Chesapeake Bay.
- The Pacific oyster, introduced from Japan, is a popular West Coast aquaculture species.
