There’s a reason why Washburn Island Oysters are being grown on the oldest aquaculture grant in the state. As early as 1877, shell fishermen have known that these waters hold magical properties.

Washburn Island Oysters spend their lives in the warm, nutrient-rich waters of Waquoit Bay, which is buffered by an estuarine research reserve on one side and Washburn Island (which is part of a state park) on the other. The result is a superior, fresh-tasting briny oyster with a super clean finish.

Since 2011, Washburn Island Oysters has been proud to uphold a strong tradition of environmental stewardship. We recognize that our business is also part of the local ecosystem, contributing year-round food and jobs to the local economy. As biologists, nature lovers and small business advocates, we proudly participate in studies that will lead to better understanding of aquaculture and its benefits for the environment. Washburn Island Oysters is a HACCP-approved shellfish wholesaler, dealer and seed propagator and is on the Interstate Shellfish Shippers List.

  • Unlike some fin-fish operations, oyster aquaculture requires no fertilizer, feed, herbicides, chemicals or antibiotics.
  • Oysters filter feed on algae in the water column, drastically reducing the incidence of unsightly algal blooms.
  • A single shellfish can filter over 50 gallons a day of water, removing nitrogen and other nutrients that throw estuaries out of balance.
  • Oysters provide and improve habitat for other aquatic species, leading to greater biodiversity.


  • Eastern oysters are a low-calorie, low fat source of protein: a serving size of six oysters adds up to 57 calories, 2 grams of fat, and 6 grams of protein.
  • Do you know that an oyster contains essential minerals that you won’t find in most seafood? A serving size of oysters provides you with 500% of your daily value of zinc, 187% of copper, 76% of selenium and 30% of iron.
  • Zinc supports your immune system, helps wounds heal faster and is especially important for child development.
  • Oysters are high in Omega-3 fatty acids, which  help lower your blood pressure and lower your risk for heart disease and stroke.
