Oysters & Clams

Brought to you by:

Maryland residents may harvest oysters and clams for recreational purposes. No license is required.

Refer to maps of Maryland Shellfish Harvesting Areas for information on areas of restricted waters, closures, and coordinates of sanctuaries online via the DNR Shellfish Program webpage under related links: dnr.maryland.gov/fisheries/oysters.

You may also call the Maryland Department of the Environment hotline 800-541-1210 to obtain information on conditional closures due to water quality or other environmental issues.

Recreational shellfish regulations for the Potomac River can be found at prfc.us.

Rangia Clams

The Rangia clam is often found in Maryland in low salinity water. Many of these areas, especially those within 200 feet of shore, have not been tested or approved by the Maryland Department of the Environment for shellfish harvest, and the consumption of these clams is not recommended.

Rangia clams should not be confused with the better-known hard clam found primarily in the Coastal Bays.
