American Oysters

The American or Eastern oyster, Crassostrea virginica, is fished both recreationally and commercially in a number of the region's towns.  The culture of oysters can be traced back to the times of the Romans, and more recently the American oyster has been the more popular species for aquaculture in the area. In the wild, these shellfish are found on the surface of the sand, usually attached to some form of hard substrate.
Often considered a delicacy, oysters are very popular eaten raw, fried, or in a variety of other dishes.  Oysters are also high in protein, vitamins (A,B,C, and D) and minerals (zinc, potassium, iron, copper, calcium, and magnesium), and a great source cholesterol reducing fatty acid Omega-3.  So, not only are they delicious, but nutritious too!
The natural or wild populations of oysters in most towns in Southeastern Massachusetts are markedly lower than historical populations.  This is of concern as oysters can be a vital component of near shore ecosystems filtering large volumes of water for the algae they consume, while large groups of this species can form banks of hard structure helping to secure soft sediment shorelines from wave action and providing protective habitat to juvenile fish, lobsters, and other species.  We have worked to restore or enhance oyster populations in the area for a number of years and recent efforts have focused on the technique of remote setting of oysters to create oyster banks and rejuvenate local fisheries.
For more information on remote setting of oysters see our habitat restoration page and Marine Extension Bulletin.

  1. Oyster is very good for those people who are experiencing zinc deficiency since research are showing that oyster is a good source of zinc but some are giving us a warning that we should not eat too much oyster or our stomach cannot digest too much of this seafood that may cause diarrhea and stomach ache.
