Most newcomers assume a single "Cape Cod shellfish license" exists. It doesn't. Every one of the Cape's 15 towns runs its own recreational program, sets its own fee, picks its own permit year, and decides which flats are open on which days. Recreational diggers need a town permit from whichever town's waters they want to work. Get the wrong one and you'll get warned off (or fined) by a shellfish constable who has heard every excuse.
Below: what each town publishes for its recreational permit, how the permit years differ, how weekly limits work, and the flats worth knowing about. Every fee in the table links back to the town's own page, and anything we could not confirm is left out rather than guessed.
The rules every digger should know
There is no single Cape-wide weekly limit. Each town sets its own catch limits, and they differ more than people expect:
- Provincetown: one level 10-quart pail or a peck shellfish basket per week for any combination of quahogs, soft-shell clams, oysters and razor clams; no other containers allowed (provincetown-ma.gov)
- Harwich: one 10-quart pail per week in total, with oysters counted inside that limit when they're in season (Harwich recreational shellfish regulations)
- Wellfleet: 10 quarts per week combined for oysters, quahogs, soft-shell clams and razors, plus separate limits for mussels, scallops and surf clams (wellfleet-ma.gov regulations, updated 7-7-2026)
- Brewster: 10 quarts per week in any combination, with species caps inside that, such as 5 quarts of steamers and 5 quarts of oysters (Brewster 2026 non-commercial regulations)
- Chatham: a family permit allows up to 32 quarts per week total, no more than 12 quarts of any one species (Chatham Shellfish FAQ)
Read your own town's limit sheet before you go.
Size limits come from state regulation, and towns repeat them in their own rules. Under 322 CMR 6.20, quahogs must be at least 1 inch in shell thickness (hinge width), soft-shell clams at least 2 inches long, and oysters at least 3 inches long (322 CMR 6.20; repeated in Brewster's and Harwich's regulations). Scallops must show a well-defined raised growth ring or they count as seed and go back (Brewster 2026 regulations; Chatham Shellfish FAQ). Carry a measuring gauge. Sandwich, for one, requires you to have "a standardized shellfish measuring device" with you whenever you're shellfishing (sandwichmass.org).

Every row above was checked against that town's own published fee page or document on October 1, 2026. A few caveats, straight from those documents: Brewster's 2026 regulations still label the fee list "Fees for 2025 permits," while the town's 2026 mail-in form shows the same amounts. The fee sheet Sandwich links from its shellfish page is titled 2024-2025. The Harwich and Barnstable fee sheets carry no year. Towns can change fees mid-year, so call ahead if a dollar matters to your plans.
Permit years differ by town. Provincetown and Truro run from November 1, Chatham runs June 1 to May 30, Dennis runs on the calendar year, and Sandwich permits expire at the close of its season each fiscal year. A permit bought in one town may already be expiring in the next. Several towns also discount or waive the fee for seniors and veterans, at different ages, so ask about it when you buy.
Which towns are actually worth the permit
Buying a permit in every town isn't realistic at non-resident rates. Pick based on what you want, and check the town's open-area list before you go.
For quahogs: Barnstable and Chatham
Barnstable's Cotuit Bay and Three Bays systems are popular with beginners: shallow water and soft bottom in many spots. Chatham's Pleasant Bay side, including the Crows Pond area, is known for bigger quahogs (cherrystones and chowders) but takes more time to learn. Both towns post area closures, so confirm what's open before you drive.
For soft-shell clams (steamers): Wellfleet and Eastham
Wellfleet's Indian Neck is a noncommercial-only area. From June 1 through September 30 it's open on Sundays and Wednesdays, and from October 1 through May 31 it's open seven days a week. The rest of Wellfleet Harbor is closed to noncommercial shellfishing from June 1 to September 30 (wellfleet-ma.gov regulations). Eastham's bay-side flats are the other classic steamer ground, at a much lower non-resident fee. Bring a short-handled clam rake (not a quahog rake) and a peck basket.
For oysters: check the season town by town
Recreational oyster seasons are short and differ by town. Brewster's runs from October 1 into early March (Brewster 2026 regulations). Chatham's runs October 1 through April 30 (Chatham Shellfish FAQ). Harwich allows oysters September 1 through April 30, on open days only (Harwich regulations). Dennis lists December 1 through March 31 (town.dennis.ma.us FAQ). One important correction: in Brewster, the immediate areas of Paine's Creek, Quivett Creek, Freemans Pond and Namskaket Creek are closed to shellfishing due to contamination until further notice (Brewster 2026 regulations).
For bay scallops: lower your expectations
Wild bay scallops are scarce in most Cape waters, and seasons open only when the town says so. Chatham's FAQ lists a recreational scallop season of November 1 through March 31. Provincetown opens a season only "if bay scallops are abundant," by posted notice from the constable (provincetown-ma.gov). Finding a full limit takes serious local knowledge.
Seasons: when each species actually opens
People assume shellfishing is a summer activity. In many towns the opposite is closer to true: some of the best flats are closed or on limited days in summer.
| Example | What the town publishes | Source |
|---|---|---|
| Wellfleet, most of the harbor | Closed to noncommercial digging Jun 1 to Sep 30; open daily Oct 1 to May 31 | wellfleet-ma.gov |
| Brewster steamers | Oct 1 to May 1 | Brewster 2026 regulations |
| Dennis quahogs | Dec 1 to May 31 | town.dennis.ma.us FAQ |
| Harwich open days | Every day Jan 1 to Mar 31 (temperature dependent); Wed and Sat only Jun 1 to Sep 30 | Harwich regulations |
| Truro | Bay-side beaches open year-round, all days; Pamet Harbor and rivers Nov 1 to Apr 1, Sundays only, when posted open | truro-ma.gov FAQ |
Rainfall closures are the silent killer. Massachusetts classifies some growing areas as "conditionally approved," which means they close some of the time because of rainfall or seasonally poor water quality. The state's own advice is that "for the most current classification and closure information, harvesters should contact your local town shellfish constable" (mass.gov shellfish classification areas). Call or check your town's shellfish page before you drive. You can lose a Saturday morning to a Tuesday thunderstorm and not know it until a constable turns you back.
How to actually buy a permit
Many towns now sell online as well as in person. Brewster sells shellfish permits online year-round, and from April through September only by mail or online (brewster-ma.gov). Wellfleet and Truro both sell online (wellfleet-ma.gov, truro-ma.gov). Sandwich sells recreational permits at the Town Offices, 100 Route 6A (sandwichmass.org). Bring ID and proof of residency or a tax bill if you want the resident rate. Read the dates on the permit. Chatham's family permit runs June 1 to May 30, so one bought in July expires the following May, not the following July.
What to bring on your first dig
The gear separates people who go home with dinner from people who go home with backaches.
- Short-handled clam rake for steamers; a long-handled bull rake for quahogs in deeper water
- Measuring gauge for every species you plan to take
- Peck basket, 10-quart pail or mesh bag, whatever your town allows. Provincetown accepts only a level 10-quart pail or a peck basket; Harwich allows an open peck basket, mesh bag or calibrated bucket
- Tide chart for your specific flat, not just "Cape Cod"; low tide can arrive at different times on different flats
- Wading boots or barefoot tolerance: flat mud will own a pair of sneakers
- Your permit on your person. Sandwich requires it to be visibly displayed on your outer clothing; Brewster requires it to be worn in a visible location
Don't-miss tips
1. Time your tide, not your clock. The productive window is the stretch before and around dead low tide. A 6 a.m. low means you should be on the flat before it, with a headlamp. Showing up after the low means you're chasing rising water. Low tide arrives later each day, so plan the week, not the morning. Also check the town's legal hours: Harwich allows harvesting from a half hour before sunrise until sunset, and Brewster bans taking shellfish between sunset and sunrise.
2. Don't assume your permit covers the next town over. A Barnstable permit gets you nothing in Yarmouth or Mashpee, even where the line is invisible on the water. Constables from neighboring towns work the boundary flats because so many people get this wrong. If you're a non-resident who fishes both shores, add up both towns' fees from the table above before you commit.
Warning: closures are not advisory. When a flat is closed for red tide (PSP) or contamination, it is closed regardless of your permit, and eating shellfish from a closed area can make you seriously ill. The state notes that its growing-area classification maps "do not reflect the current open or closed status of an area" (mass.gov), so your town shellfish constable is the source to check before every trip.
The right permit, the right tide, and the right flat will put dinner on the table. The wrong combination will get you a ticket and a long drive home. Now you know which is which.

Frequently asked questions
Do I need a separate shellfish permit for each Cape Cod town?
Yes — there is no single Cape-wide license. Each of the 15 Cape Cod towns runs its own permit program, sets its own fee, and decides which flats are open. A permit from one town gives you no rights in any neighboring town's waters, even where the boundary is invisible on the water.
Is shellfishing on Cape Cod mainly a summer activity?
Not always — many towns restrict or close their best flats during the summer months, and some areas that are tightly limited in summer open daily through fall and winter. Check your specific town's published schedule before planning a trip, because the productive season can run opposite to what you'd expect.
What do I need to bring shellfishing for the first time?
Bring a rake suited to what you're harvesting, a measuring gauge for every species you plan to take, a container your town permits, a tide chart for your specific flat, and your permit on your person. Some towns require the permit to be visibly worn on outer clothing, so read your town's rules before you go.
Can a shellfish flat be closed even if I have a valid permit?
Yes — Massachusetts classifies some growing areas as conditionally approved, meaning they can close after rainfall or due to seasonal water quality regardless of your permit status. The state advises contacting your local shellfish constable for current closure information before every trip, since a storm earlier in the week can shut a flat without notice.
Do seniors or veterans get a discount on Cape Cod shellfish permits?
Most Cape Cod towns offer reduced fees or exemptions for seniors and veterans, but the qualifying age and benefit level vary considerably from town to town. Ask about it when you go to buy your permit, and confirm current rates directly with your town's shellfish office.
