Shellfish is a colloquial and fisheries term for exoskeleton-bearing aquatic invertebrates used as food, including various species of molluscs, crustaceans, and echinoderms. Although most kinds of shellfish are harvested from saltwater environments, some are found in freshwater. In addition, a few species of land crabs are eaten, for example Cardisoma guanhumi in the Caribbean. Shellfish are among the most common food allergens.
Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified, and many are somewhat irregular in shape. Many, but not all oysters, are in the superfamily Ostreoidea.
Port Phillip or Port Phillip Bay is a horsehead-shaped enclosed bay on the central coast of southern Victoria, Australia. The bay opens into the Bass Strait via a short, narrow channel known as The Rip, and is completely surrounded by localities of Victoria's two largest cities — metropolitan Greater Melbourne in the bay's main eastern portion north of the Mornington Peninsula, and the city of Greater Geelong in the much smaller western portion north of the Bellarine Peninsula. Geographically, the bay covers 1,930 km2 (750 sq mi) and the shore stretches roughly 264 km (164 mi), with the volume of water around 25 km3 (6.0 cu mi). Most of the bay is navigable, although it is extremely shallow for its size — the deepest portion is only 24 m (79 ft) and half the bay is shallower than 8 m (26 ft). Its waters and coast are home to seals, whales, dolphins, corals and many kinds of seabirds and migratory waders.
The Port River is part of a tidal estuary located north of the Adelaide city centre in the Australian state of South Australia. It has been used as a shipping channel since the beginning of European settlement of South Australia in 1836, when Colonel Light selected the site to use as a port. Before colonisation, the Port River region and the estuary area were known as Yerta Bulti by the Kaurna people, and used extensively as a source of food and plant materials to fashion artefacts used in daily life.
Ardrossan is a town in the Australian state of South Australia located on the eastern coast of the Yorke Peninsula, about 150 kilometres (93 mi) by road from the Adelaide city centre. It is notable for its deepwater shipping port and its towering coastal cliffs of red clay.
Oyster farming is an aquaculture practice in which oysters are bred and raised mainly for their pearls, shells and inner organ tissue, which is eaten. Oyster farming was practiced by the ancient Romans as early as the 1st century BC on the Italian peninsula and later in Britain for export to Rome. The French oyster industry has relied on aquacultured oysters since the late 18th century.
Saccostrea glomerata is an oyster species belonging to the family Ostreidae.
Yaquina Bay is a coastal estuarine community found in Newport, Oregon. Yaquina Bay is a semi-enclosed body of water, approximately 8 km² (3.2 mi²) in area, with free connection to the Pacific Ocean, but also diluted with freshwater from the Yaquina River land drainage. The Bay is traversed by the Yaquina Bay Bridge.
Ostrea edulis, commonly known as the European flat oyster, is a species of oyster native to Europe. In Britain and Ireland, regional names include Colchester native oyster, mud oyster, or edible oyster. In France, Ostrea edulis are known as huîtres plates except for those that come from the Belon River estuary in Brittany, France, which are known as Belons.
St Kilda is a coastal suburb in Adelaide, South Australia. Its seafront faces the Barker Inlet, which is part of the Port River estuarine area, the largest tidal estuary of Gulf St Vincent, and includes a large area of mangroves. St Kilda is an internationally recognised bird watching area with over 100 species of birds feeding in and around the mudflats, salt lagoons, mangroves and seagrass beds, which are part of the estuarine ecosystem.
O'Sullivan Beach is a seaside suburb in the southern Adelaide metropolitan area, within the City of Onkaparinga. O'Sullivan Beach has a unique postcode of 5166.
Netarts Bay is an estuarine bay on the northern Oregon Coast of the U.S. state of Oregon, located about 5 miles (8.0 km) southwest of Tillamook. The unincorporated community of Netarts is located on the north end of the bay and Netarts Bay Shellfish Preserve, managed by Oregon Department of Fish and Wildlife, is located on the south side of the bay. The sand spit on the west side of Netarts bay is part of Cape Lookout State Park.
Ostrea lurida, common name the Olympia oyster, after Olympia, Washington in the Puget Sound area, is a species of edible oyster, a marine bivalve mollusk in the family Ostreidae. This species occurs on the northern Pacific coast of North America. Over the years the role of this edible species of oyster has been partly displaced by the cultivation of non-native edible oyster species.
Aquaculture in Australia is the country's fastest-growing primary industry, accounting for 34% of the total gross value of production of seafood. 10 species of fish are farmed in Australia, and production is dominated by southern bluefin tuna, Atlantic salmon and barramundi. Mud crabs have also been cultivated in Australia for many years, sometimes leading to over-exploitation. Traditionally, this aquaculture was limited to pearls, but since the early 1970s, there has been significant research and commercial development of other forms of aquaculture, including finfish, crustaceans, and molluscs.
Marteilia is a protozoan genus of organisms that are parasites of bivalves. It causes QX disease in Sydney rock oysters and Aber disease in European flat oysters. After being infected by Marteilia, bivalves lose pigmentation in their visceral tissue, and become emaciated.
Oyster reef restoration refers to the reparation and reconstruction of degraded oyster reefs. Environmental changes, modern fishing practices, over harvesting, water pollution, and other factors, have resulted in damage, disease, and ultimately, a large decline in global population and prevalence of oyster habitats. Aside from ecological importance, oyster farming is an important industry in many regions around the world. Both natural and artificial materials have been used in efforts to increase population and regenerate reefs.
The term oyster reef refers to dense aggregations of oysters that form large colonial communities. Because oyster larvae need to settle on hard substrates, new oyster reefs may form on stone or other hard marine debris. Eventually the oyster reef will propagate by spat settling on the shells of older or nonliving oysters. The dense aggregations of oysters are often referred to as an oyster reef, oyster bed, oyster bank, oyster bottom, or oyster bar interchangeably. These terms are not well defined and often regionally restricted.
Rogues Point is a locality in the Australian state of South Australia located on the east coast of Yorke Peninsula immediately adjoining Gulf St Vincent, about 80 kilometres north-west of the Adelaide city centre and about 6.9 kilometres of the centre of Ardrossan.
The Whangateau Harbour is a natural harbour in New Zealand. It is a sandspit estuary, located on the north-eastern coast of the Auckland Region north-east of Matakana, and empties into the Hauraki Gulf. Due to the harbour's high quality water and dense shellfish beds, the harbour is a popular spot for shellfish gathering.
Theodore Cleveland Roughley (1888—1961) was an Australian zoologist, author, and public servant. He is best known for his work on the Sydney Rock Oyster and its commercial cultivation, and for his books and other publications, mainly on marine science, which he skillfully illustrated with his own artwork and photography. In the later part of his career, as Superintendent of Fisheries, he implemented measures for the scientific management of fisheries in New South Wales, including catch size limits and closures of certain waters to commercial fishing. He was a well-known and influential public figure in his time. He was also known informally as Ted Roughley and, as an author, T. C. Roughley.
