Once the fish factories and ‘kidneys’ of colder seas, Australia’s decimated shellfish reefs are coming back

Australia once had vast oyster and mussel reefs, which anchored marine ecosystems and provided a key food source for coastal First Nations people. But after colonisation, Europeans harvested them for their meat and shells and pushed oyster and mussel reefs almost to extinction. Because the damage was done early – and largely underwater – the destruction of […]

World Ocean Day 2022: Restoring our Lost Reef Ecosystems

Today we celebrate World Ocean Day! Environment Institute marine researchers are using the natural relationships between bivalves and macroalgae to enhance the restoration of South Australia’s lost reef ecosystems. Over 150 years ago, oyster reefs, kelp forests, and seagrass meadows lined the South Australian coastline. These ecosystems provided a rich and productive marine environment but […]

Baby oysters follow the crackling sound of snapping shrimp

Though oysters may be brainless bivalves, they can “hear” and swim towards attractive sounds of the sea. We played the crackling sound of snapping shrimp, which indicates a healthy reef, to baby oysters using underwater speakers. We discovered the oysters swim towards the sound.  This opens the possibility of playing marine sounds to attract oysters […]

South Australia’s second large-scale oyster reef restoration will be constructed off the Adelaide metropolitan coast

A new shellfish reef is to be built at Glenelg, signalling a rapid transition from environmental amnesia to conservation action. In a stark contrast to the historical baseline of South Australian oyster reefs, University of Adelaide researchers’, Professor Sean Connell and Dr Heidi Alleway had discovered 1,500 km of Southern Australia coastline reefs had been lost […]

VIDEO: How South Australian Oyster Reefs Are Being Created

In a previous blog post here, it was shown that University of Adelaide Researchers Dr Dominic McAphee and Professor Sean O’Connell together with industry partners, have successfully begun the $4.2 million project of rejuvenating the Windara Reef, bringing back 1 million oysters to date, in the Spencer Gulf of South Australia. The question is, how can this be achieved on such […]

Massive Restored Reef Aims to bring South Australia’s Oysters Back

Researchers from the University of Adelaide have undertaken the largest oyster reef restoration project outside the United States in the coastal waters of Gulf St Vincent, near Ardrossan in South Australia. Construction began earlier this month with some 18,000 tonnes of limestone and 7 million baby oysters set to provide the initial foundations for a 20-hectare reef. […]

New artificial reef to be built to support local marine habitats

A new $600,000 artificial reef system is to be built south of Ardrossan, informed by research by the Environment Institute’s Professor Sean Connell and PIRSA’s Dr Heidi Alleway. The artificial reef, which is to be constructed from limestone, oyster shells and live native oysters, is part of a $3.52m State Government initiative to enhance the experience […]

Building blue infrastructure in South Australia through restoration of native shellfish reefs

The Natural Resource Management (NRM) Science Conference showcases the science underpinning environmental decision making, policy and management in South Australia, featuring some of our phenomenal Environment Institute researchers. Dr Heidi Alleway presents a seminar on the restoration of native shellfish reefs. South Australia was once home to an extensive oyster fishing industry, with oyster reefs hugging […]

Podcast: Recovering historic oyster reefs

Around 150 years ago oyster reefs lined our coastline, improving water quality, clarity and fish life. Unfortunately, due to the reefs being harvested to extinction we now have a much less healthy ecosystem. However, a collaborative venture between the University of Adelaide and SA Water is about to begin to restore the lost oyster reefs. […]

Media Release: Oyster ecosystems a huge loss for South Australia

Researchers at the University of Adelaide have discovered the loss of one of the State’s most significant marine ecosystems, which may have disappeared some 70 years ago. For her PhD in the University’s School of Biological Sciences, Heidi Alleway and supervisor Professor Sean Connell identified the loss of oyster reefs, formed by the native oyster Ostrea angasi, from […]
