Recreational harvest of various types of shellfish is an activity enjoyed by many New Hampshire residents. State licenses are required to harvest softshell clam and oysters; other shellfish may have certain restrictions on taking, but require no license. Softshell clams are dug from flats at or near low tide. For advice on proper clam digging techniques, see below. Oysters are brought up from their shallow beds using tongs or simply picked up by hand. For season, limit and take requirements for shellfish, see Shellfish.
Shellfish Maps Online
Shellfish harvesters have a great tool making it easier to find out what areas are open for harvest. You can now get updates on the status of the clam flats and other coastal areas, including red tide alerts, on your mobile phone or computer via an interactive website hosted by the N.H. Department of Environmental Services. Interactive maps show areas open for harvest. Use a personal computer to sign up for free text or email alerts at xml2.des.state.nh.us/CoastalAtlas/Atlas.html. The information matches the weekly Clam Hotline message, but comes to you on the devices you use.
