They develop a deeper cup than beach cultured oysters. They also do not have to filter as much sand & mud in order to get nutrients, thus they grow faster. Oysters raised by the rack & bag method are protected from predators and do not become cramped for space as they grow. Rack & Bag cultured oysters (also called On Bottom Cages) are grown in mesh cages or bags which are generally staked about one to two feet off the bottom. Examples of beach cultured oysters include: Bald Point, Dosewallips, Fanny Bay, Marrowstone, and Totten Virginica. And their ability to close tightly, coupled with their hard shells, gives them a longer shelf life. They have hard, sturdy shells which shuckers like to work with. Because of this “tough” life, beach raised oysters are hearty. These oysters are accustomed to fighting the tides, clamping tightly shut during low tides to preserve their “liquor” and to protect themselves against predators. Bottom or Beach Cultured Oystersīeach/Bottom Cultured Oysters, also called Intertidal Cultured Oysters, are oysters which are raised on tidal beaches with sandy or rocky bottoms. Tumbling is a variation of Suspension Cultivation where suspended oysters are tumbled to increase shell strength and meat texture. Bag to Beach is a combination of Rack & Bag cultivation & Beach cultivation. Two additional variations are Bag to Beach and Tumbling. Each method imparts different qualities to the oyster flavor profile, texture, and shell characteristics. Beach or Bottom Cultured (or Intertidal Cultured), Rack & Bag Cultured, Longline Cultured, Suspended Tray or Suspended Lantern Cultured.
