Ostrea angasi, also known as the Southern mud oyster or Australian flat oyster, is a species of oyster native to the southern coastlines of Australia. It is named after the British zoologist Arthur Angas, who first described the species in 1865.
Description[edit]
The Ostrea angasi is a bivalve mollusc with a shell that can reach up to 15 cm in length. The shell is flat and oval-shaped, with a rough, scaly surface. The colour varies from white to grey, with purple or blue hues. The interior of the shell is smooth and white, often with a purple or pink tint.
Habitat and Distribution[edit]
The Ostrea angasi is found along the southern coast of Australia, from Western Australia to New South Wales, and also in Tasmania. It inhabits intertidal zones and subtidal areas up to 50 meters deep. The species prefers muddy or sandy substrates and is often found in estuaries and bays.
Ecology[edit]
The Ostrea angasi is a filter feeder, consuming plankton and other small particles in the water. It plays a significant role in the ecosystem by improving water quality and providing habitat for other marine species. The species is also a food source for various predators, including birds, fish, and humans.
Commercial Use[edit]
The Ostrea angasi has been commercially harvested in Australia since the 19th century. It is considered a delicacy and is often served raw or cooked in various dishes. However, overfishing and disease have led to a decline in populations, prompting efforts to farm the species sustainably.
Conservation[edit]
Conservation efforts for the Ostrea angasi include habitat protection, regulation of harvest, and aquaculture. Several programs are in place to restore populations, including the use of artificial reefs and hatchery-reared juveniles.
