A raw-bar trailer under the tent at Nomans in Oak Bluffs, island oysters shucked to order. The oysters on the ice were in the water that morning or the one before.
Where Martha's Vineyard's oysters, bay scallops and quahogs come from: the public solar hatchery on Lagoon Pond that turned fifty in 2026, the dozen oyster farms in Katama Bay, Menemsha Pond and Vineyard Sound, the wild beds in the great ponds, the autumn scallop season and its limits, visitor shellfish permits by town, why rain closes a pond, and where to eat them.
The oyster on the ice in front of you at an Edgartown raw bar has a short, local biography. It was very likely spawned in a solar-heated hatchery on the shore of Lagoon Pond, set out as seed in a town pond or a bag in Katama Bay, tended for two or three years by one of about a dozen island farmers, and shucked within a day of coming out of the water. This guide is the whole chain: the fifty-year-old public hatchery that made the island's shellfish possible, the ponds where oysters, quahogs and bay scallops grow, the farms and their tours, what the seasons and the permits are if you want to dig your own, why a summer rainstorm closes a pond, and where to eat the result.

Almost every shellfish story on the island runs through the Martha's Vineyard Shellfish Group, a public non-profit that turned fifty in 2026. It was founded in 1976 when the six towns hired a young biologist, Rick Karney, to help their shellfish constables rebuild stocks that fishing and disease had thinned; he built the first pilot hatchery on Lagoon Pond the following year out of materials salvaged from the dump, and in 1980 the group opened the solar hatchery that still stands on the Tisbury shore of the Lagoon, the first public solar shellfish hatchery in the United States. It spawns bay scallops, quahogs and oysters and sets the seed out in the towns' ponds, on the order of twenty to thirty million animals a year and more than half a billion over its life. Two side projects changed the island's food: a selective-breeding programme that produced orange-shelled and striped scallops as living tags, and, in the 1990s, a federally funded training course that taught island fishermen to farm oysters and launched the industry the raw bars now depend on. The group is run today by a director who came up through it, funded by the towns and by donations, and it will teach your children to shuck at its touch tank if you ask. Our Lagoon Pond walk passes the hatchery.
The shore path to Sengekontacket, the pond that gives Oak Bluffs and Edgartown their scallops. Closed to shellfishing in summer, open with a town permit from autumn.

Oyster farming is the crop every aquaculture start-up in the Northeast chose, and by the mid-2020s there were more oysters than buyers. The hard winter of 2025 to 2026 changed that in the island's favour, the Vineyard Gazette reported in April 2026: the ice that froze the great ponds and damaged farms on the mainland mostly spared the island's cages, killed off the barnacles and mussels that foul the gear, and sent the oysters into a plumping spring while off-island distributors rang the farmers looking for supply. Chilmark extended its wild season to May 9 to let harvesters catch up. None of that is visible on the ice at the raw bar, which is the point of the raw bar.
The bay scallop is the island's most loved shellfish and the one visitors miss, because its season begins the month the visitors leave. It lives one to two years in the eelgrass of the ponds, and the town rules allow only adults with a raised growth ring to be taken, by hand, dip net or push rake, never by dragging in the recreational season. In the 2025 season Edgartown's family season opened on October 1 with a limit of one ten-gallon basket a week, shells included; Oak Bluffs opened Sengekontacket to recreational scallopers on October 14 and the Lagoon on November 2; Chilmark opened on October 14; and Edgartown's commercial season ran from October 21 to the end of March at three baskets a day. The harvest swings wildly with the eelgrass and the weather: Edgartown landed about 3,000 bushels in the 2025 to 2026 season against more than 10,000 the year before. The towns post each autumn's dates in September; our fall guide carries them. A bay scallop eaten the day it is opened, seared for a minute in butter, is the best thing the island produces, and it is on the year-round restaurants' menus from late October.
Every town sells shellfish permits to visitors, at prices that say something about the town. Tisbury, as reported for 2026, sells a non-resident permit for $25 a week, $75 a month or $400 a year; Aquinnah a weekly family permit at $45, mostly for Menemsha Pond; Chilmark a non-resident permit at $150, dip-net only; Edgartown through its shellfish department at 135 Meetinghouse Way (508-627-7570), whose fees are not posted online; Oak Bluffs an annual non-resident permit. A permit comes with a map of open and closed areas, the weekly limits, and the state minimum sizes (an oyster must be three inches, a quahog an inch thick across the hinge, a bay scallop must carry its growth ring), and the constables check baskets on the landings. Quahogs are the visitor's shellfish: year-round, in the sound-side ponds and harbours, by rake from a beach you can walk to. Ask the department which flats are open that week and read our rules and etiquette guide for the manners on a flat where the person next to you is filling the family freezer.
A restaurant on the Lagoon shore at Beach Road, the hatchery a short way along the same water. The Lagoon is the island’s working shellfish pond: seed goes in from the hatchery, scallops come out in November.
Shellfish filter the water they sit in, which is the argument for them and the risk of them. After heavy rain, runoff pushes bacteria counts in the sheltered ponds past the state's limits, and the Division of Marine Fisheries closes the affected growing areas to harvest until tests come back clean; Sengekontacket was closed from early July to late August 2026 after the summer's storms, and the down-island ponds close on a schedule every summer for the same reason. A closed pond is closed for eating, not for swimming or paddling, though the same bacteria drive the beach advisories our beach safety guide explains. The oysters at the raw bar in July come from the open waters, the Sound, Katama Bay and the farms, which is one more reason the island's growers moved there. The ponds themselves, the cuts and the blooms, have their own guide.

The Shellfish Group’s history and programmes are from the Vineyard Gazette’s fiftieth-anniversary report of June 11, 2026 and the group’s own history; the seed numbers from the group’s reporting over the years and our Lagoon Pond walk. The farms, the 2026 winter and the Chilmark wild-oyster limits are from the Gazette of April 26, 2026; Cottage City’s certification and sales from the farm’s site. Scallop season dates and limits are the towns’ 2025 season notices as reported by the Gazette and the Martha’s Vineyard Times, and the 2025 to 2026 landings from the Times of June 18, 2026; the towns set new dates each September. Permit fees are as reported for 2026 and change with town votes; the shellfish department is the only reliable source on the day. State size limits are the Massachusetts minimums. The photographs are ours.
Island tip of the daySeasonalNo. 77 of 86
The first two weeks of June are genuinely quiet. Most businesses are open but visitor numbers are low. Perfect for couples. Downside: water is cold (55–60°F) and fog is common.
Martha's Vineyard's ponds explained: the great ponds sealed behind the south-shore beach and cut open to the sea by hand, the salt ponds with tides and scallops, the freshwater kettle ponds, why cyanobacteria blooms turn some of them green in August and what MV Cyano's colours mean, the nitrogen under the houses, and where a visitor can swim, paddle and watch the cut.
Lobster on Martha's Vineyard from trap to paper plate: how the small Menemsha fleet fishes, the Massachusetts rules on size, egg-bearing females and whale-safe gear, where to buy lobster off the boat (Larsen's, Menemsha Fish Market, The Net Result), how to eat it on the dock with your own bottle, and how a visitor can get a permit and catch a few.
