In 2025, the Crowes Pasture Aquaculture Area sold about 19,000 bushels of oysters. Recreational permit holders across all of Dennis took about 6 bushels of soft-shell clams and 2 bushels of bay scallops, and those totals cover every family permit in town, from every beach. The flats at the end of Crowes Pasture Road are some of the busiest working water in town. They are mostly commercial farm ground. Most of the family shellfishing in Dennis happens on the south side of town, along Bass River.

That changes how an East Dennis household might plan the next five months. Cape Cod Bay scallops open this Sunday, November 1, and north-side clam flats have been open since early October. December brings the biggest family harvest of the year, and the town runs it in coves about as far from Sesuit Harbor as you can get without leaving Dennis.

The 2025 numbers

These figures come from the Dennis Shellfish Committee's 2025 annual report, which was attached to the committee's February 18, 2026 minutes.

The town issued 334 recreational permits that year, and the committee calls recreational shellfishing "a popular winter activity in town." The two largest family totals, quahogs and oysters, both came from Bass River sites. The town's own FAQ points permit holders to West Dennis Beach for oysters and Cove Road for quahogs, and calls both town propagation sites.

The grant area at Crowes has a waitlist of 19 applicants, and two new grant holders started farming oysters in 2025. The Natural Resources team has spent its propagation money on the south side, and that's where the family harvest follows.

What's open on the north side right now

A town notice posted September 28, 2026 opened recreational soft-shell clams in Cape Cod Bay on Saturday, October 3, for Mondays and Saturdays. The town's recreational shellfish regulations list Chapin Beach and Crowes Pasture as the two north-side clam areas, open from October through May 31. For East Dennis, this is the one family harvest that happens close to home.

The rules for a clam day at Crowes are specific:

• Days: Mondays and Saturdays only, so the next two are Halloween and November 2.
• Limit: ten quarts per household permit per week, and the town's week starts on Sunday.
• Size: nothing under two inches the long way. The town suggests using a two-inch ring.
• Tools: a conventional clam digger or a hand plunger only. Shovels, hoes and rakes aren't allowed, and diggers have to cover seed and refill their holes.
• Marsh edge: no digging within two feet of marsh grass, marsh roots or peat.
• Daylight: no harvesting between sunset and sunrise.

One more rule starts to matter as the season turns. When the air temperature is 32°F or lower, shellfishing isn't allowed at all, except for quahogs, oysters and sea clams. So a frosty morning at Crowes cancels a clam outing. Quahogs and oysters can still be harvested in that weather, and both of those are Bass River seasons.

November 1 and the check-in at Sesuit Harbor

The September notice says bay scallops opened October 1 in Nantucket Sound, with West Dennis Beach as its example, and that "all other areas" open November 1, 2026. That includes Cape Cod Bay. Under the regulations, family scallop harvest is allowed every day, Sundays included, with a limit of one bushel per household permit per week. Only adult scallops with a well-defined growth line may be kept, and everything else goes back in the water alive right away.

Sesuit Harbor plays a small official role here. Recreational permit holders who scallop Cape Cod Bay by power dredge check in with the Shellfish Constable in Sesuit Harbor while landing. The harbor will feel quieter than it did in August. Sesuit Harbor Cafe has already posted "Thank you for another great season. See you next year!" on its homepage.

Keep expectations modest. Last year the whole town's recreational scallop harvest was about two bushels, two weeks' worth of limits for a single household. The town's scallop restoration work is on Bass River too. In 2025, about 100,000 bay scallop seed were grown in lantern nets at Packet Landing in Yarmouth and released into Bass River over the late summer and fall, in partnership with the Town of Yarmouth and Friends of Bass River. The Shellfish Constable's scallop project with those same partners came up again at the committee's April 2026 meeting.

December moves the action south

The two seasons that produce real family harvests open in December, and the regulations put both on Bass River. Oysters come from Main Bass River between the mouth and the landing at Old Fish House Road, including Grand Cove and Wilbur Cove, on Sundays only, with a limit of 48 per household permit per week. Quahogs come from an area the Shellfish Constable designates in Grand Cove, Wilbur Cove or Main Bass River north of Route 28, on Mondays and Saturdays, with a limit of ten quarts per week.

The town restocks those coves. The 2025 report describes:

1. About 100,000 quahog seed and 150,000 oyster seed grown in the town's upwellers over the summer and spread in Bass River for both family and commercial areas.
2. 160 bushels of quahogs relayed from Fall River and moved into the Grand Cove family area.
3. 150 bags of remote-set oysters added to the family harvest area at Old Field Bend.

Opening dates in December can shift. Last season, recreational quahogs opened Monday, December 1, 2025, and oysters opened Sunday, December 7, 2025, according to the town's December 2025 notice. The regulations say the Shellfish Constable can change opening and closing dates. So the notice the town posts this winter will set this year's December dates.

Last winter also showed how weather can rewrite the calendar. At the March 18, 2026 committee meeting, the Shellfish Constable said family harvesters had lost about four weeks of oystering at West Dennis to a thick ice sheet. He planned to ask the Select Board to extend the season from the usual last Sunday in March to the last Sunday in April. The same ice reached East Dennis. In February the constable reported the Crowes ORV route closed because the road was hard to get through. In March, a grant holder with twenty years on Crowes Pasture told the committee that the ice pack had severely impacted most of the infrastructure on his grant.

The permit runs out on December 31

Dennis recreational shellfish licenses run from January 1 to December 31. A license bought for this weekend's scallop opener covers about nine weeks: November, December, and the start of the Bass River quahog and oyster seasons. Last year, next year's licenses went on sale December 1, the same day quahogs opened. The town hasn't posted this year's on-sale date yet.

The practical details, from the town's notice, FAQ and department directory:

• Where: the Natural Resources Department in Dennis Town Hall, 685 Route 134, South Dennis.
• Hours: Monday through Friday, 8:30 a.m. to 4:30 p.m. Phone 508-760-6123.
• Cost: $40 for Dennis residents and $100 for non-residents. The town FAQ lists $12 for residents over 70, and veterans pay resident rates under the BRAVE Act.
• Payment: cash or check only. No credit or debit cards.
• Bring: a driver's license and one more document showing your Dennis address, such as a property tax bill or a utility bill. To renew, bring your current license and the office adds a new sticker for the year.
• Who can use it: the town's shellfish FAQ says anyone from a household may use a family permit. The regulations say the holder's spouse or unmarried children may use it if they carry the permit, so ask the office how that applies to your household.

Once you're on the flats, the regulations require the permit to be displayed where it can be plainly seen on your clothing. The Shellfish Constable is Jordan Halloran, and Erin Burnham directs the department. Their office is the place to ask about current closures. The state's shellfish classification maps include Quivett Creek and Sesuit Harbor, but the Division of Marine Fisheries says the maps don't show whether an area is open or closed today, and it sends harvesters to their local shellfish constable.

This post is general information, not legal advice. Shellfish rules, fees and dates are set by the Town of Dennis and the state, so confirm them with the Natural Resources Department before you head out.
