Do You Need a License to Dig for Clams on Cape Cod?

Yes, you need a permit—but it's free and easy to get. The Massachusetts Division of Marine Fisheries (DMF) requires a Recreational Shellfish Permit for anyone harvesting clams, oysters, mussels, or quahogs on Cape Cod.

How to Get It

• Online: Mass.gov shellfish permit page – instant PDF.
• In person: Any DMF office (New Bedford, Gloucester, Boston) or many town halls on the Cape.
• Cost: Free for Massachusetts residents; non-residents may pay a small fee (check current regs).

Critical Rules

• Check local town regulations: Each Cape town (Barnstable, Brewster, Chatham, etc.) sets its own open seasons, daily limits, size limits, and allowed areas. Many require a separate town permit (often free for residents, fee for non-residents).
• Red tide / contamination closures: Check DMF closure maps before digging.
• Tools: Hand tools only (rake, fork, hands); no mechanical harvest.
• Size limits: e.g., Quahogs ≥1" hinge width; Soft-shell clams ≥2".

Always verify current rules with the MA DMF and the specific town's shellfish constable.
