New Hampshire has oysters, clams and mussels accessible for recreational harvest. License may be required.

Mollusks (clams, oysters, mussels, etc.) may only be taken from approved areas. (See maps of Shellfish Areas).
Motor vehicles are prohibited on clam flats (any tidal area, exposed at low tide, that is capable of growing clams).
Call 1-800-43-CLAMS for current open/closed status of NH shellfish areas. Temporary closures during open seasons may occur due to high bacteria levels, red tide or other issues.
Sale prohibited. Softshell clams and oysters of N.H. origin, and quahogs, littlenecks and cherrystones (Mercenaria mercenaria) less than 1 inch in shell thickness cannot be sold.
