Shellfish reefs were once abundant across South Australia, covering more than a third of our coastline.
They teemed with oysters, mussels, crabs, cuttlefish, prawns and fish; supported a significant oyster fishery; and were important to the diets of Aboriginal people.
Since European settlement, shellfish reefs have gradually disappeared. Dredging, overfishing and degradation caused by urban development has made these reefs some of the most endangered marine habitats on Earth.
Enter The Nature Conservancy (TNC). They’re on a mission to rebuild shellfish reefs across southern Australia.
