Port Stephens once boasted an abundance of oyster reefs, which played a vital role in the health of the marine ecosystem.
But, sadly, that isn’t a fact anymore.
More than 99% of the oyster reefs are considered “functionally extinct” because of a combination of overfishing, habitat destruction, catchment clearing and water-quality degradation, land reclamation and disease.
However, there’s some good news on the horizon.
Thanks to a landmark project by the NSW Department of Primary Industries, restoration of the reefs is underway.
And, to acknowledge the ground-breaking initiative, the Tomaree Museum Association (TMA) – in conjunction with the Australian Maritime Museum – will host a special month-long exhibition at the Port Stephens Visitor Information Centre in Nelson Bay from Wednesday 7 February.
Bidhiinja invites audiences to learn about the past, present and future of oyster reefs in Australia and the benefits they provide to communities and the environment.
“Oyster reefs are a complex ecosystem and home to more than 300 marine animals such as shrimp, crabs, clams, snails and worms, as well as many fish species,” TMA president Doug Cross said.
“Without them, the water is dirtier, fish and crustaceans suffer, and shorelines are less stable.
“Reef restoration, which began in 2019, has resulted in the creation of a Sydney Rock Oyster (Saccostrea glomerata) reef equivalent in size to 11 soccer pitches, on which 34 million oysters have been established.
“The project is showing signs of success.
“It’s filtered nine million litres, or three-and-a-half Olympic-sized swimming pools of water an hour and supporting increased numbers of fish and invertebrates.”
Bidhiinja shares the story of the oyster reefs’ rich history, important cultural value and significant advantages to local and estuaries.
The exhibition, on display until 8 March, is funded by the NSW Government through the Marine Estate Management Strategy, which aims to deliver a healthy coast and sea.
