The purpose of the Pumicestone Passage Shellfish Reef Restoration project is to restore shellfish reef populations for the benefit of the Moreton Bay ecosystem and the community.

Not only are shellfish a vital part of Indigenous cultural heritage, but they are also an incredibly important cog in marine ecosystems. Shellfish are fondly known as the “kidneys of the coast” due to their natural filtration properties and for their ability to improve water clarity by drawing in particles and distributing them to the seafloor.

Once grown, each shellfish can filter up to 100 litres of water a day, helping to create an environment that allows many other plant and animal species in estuaries and coastal bays to thrive.

If the method used in the Pumicestone Passage restoration project proves to be successful, and self-sustaining subtidal oyster reefs are established, the data and outcomes can be used to justify and inform larger-scale restoration efforts in other areas of Moreton Bay.
