Eastern Oyster

Eastern oysters are harvested and cultured in shallow bays and estuaries around Prince Edward Island, although their natural range extends as far south as the Caribbean and the Yucatan Peninsula. This oyster prefers brackish water (a mix of salt and freshwater) between eight and 35 feet deep. They are found grouped together in oyster beds. They are slightly smaller and have a smoother shell than the Pacific oyster. These hardy shellfish prefer rocky bottoms but can live in a variety of subtidal and intertidal habitats.

The Eastern oyster has smooth edges and a cupped, oval shape. The shell’s interior is usually off-white to brownish in colour with occasional purple markings. It can grow up to eight inches (24 cm). It has creamy white meat with a firm texture and a mild, sweet flavour that can vary widely depending on cultivation methods and the marine environment.

Eastern Oyster

Eastern oysters grow quickly and reproduce rapidly. They first mature and reproduce as males, then later develop into females. Spawning is seasonal and depends on water temperature. Females are very fecund, producing 100 million eggs during the spawning season. Larvae (also known as spat) disperse into the water column and eventually settle on the seafloor. At this stage, the oyster has developed a foot that secretes a liquid cement to attach itself to a hard surface, preferably the shell of other oysters. They can grow three inches in three years. While most Eastern oysters are harvested in the wild, some are farmed. The oysters are grown using a variety of techniques: they can be placed on the seafloor, suspended in mesh bags or trays in the ocean or attached to rope and wooden frames in the intertidal zone. Different cultivating methods and the marine environment drastically affect the flavour, texture and appearance of Eastern oysters, allowing shellfish growers to create distinctive regional brands, whether farmed or wild.

TASTING NOTES

  • Colour: creamy white meat
  • Texture: firm texture
  • Flavour: A sweet, mild taste.
  • Perfect serve: Oysters are popular served raw on the half-shell, but are also served baked, steamed, grilled or in specialty dishes such as Oysters Rockefeller. The flavour, texture and look of raw oysters reflects cultivation methods and local ecological conditions. Shucked oysters can be sautéed, steamed, grilled, or used in soups or other dishes. Oysters require very little cooking time and should be heated slowly. Regardless of the cooking method used, cook only till the mantle begins to curl.

These crabs mate at the time of maturity, which is approximately 3 years of age. Females are smaller than males; this is because the development of reproductive tissues required more energy for females, leaving less energy available for continued body growth. They grow through a process known as molting—regularly shedding their shell and growing a new, larger one. They continue to molt and grow after they have reached sexual maturity. During the breeding season, the crabs leave their borrows in a phenomenon characterized by mass mate-searching events. Once mating/fertilization has occurred, females spawns in the water. The larvae released during the rainy season develop in offshore waters and return to coastal waters five to eight weeks after larval release.
Mangrove crabs are important fishery resources in all Brazilian coast, mainly in the north and northeast where many fishermen depend upon their catch. In addition to its social and economic importance, the mangrove crab is a “keystone” species in ecosystem, they playing an important role in the processes of nutrient cycling and energy transfer.

Fishing Methods

{'fisheries': [<License: Eastern Oyster by Tongs>], 'gear': <Gear: Oyster Tongs>}

Oyster Tongs

Fish harvesters use long, hand-held stainless-steel tongs to harvest oysters. The tongs look like a pair of rakes with long handles fastened together, scissor-fashion, about one-third the way up from the rakes.
