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.
