South Australians are being encouraged to consume local oysters, mussels, and scallops as part of an environmental project that uses discarded shells to rebuild coastal reefs lost over a century ago. The collected shells are sunbaked, placed in wire crates, and deployed on the sea floor to provide a substrate for new reef growth, helping filter water and control algae.

This initiative comes as the state faces a toxic algal bloom, with thousands of shells needed to construct 25 community reefs. Collection bins have been set up statewide, and a new volunteer portal has been launched to involve the community in shellfish restoration and other environmental programs.

South Australians urged to eat shellfish to help reef restoration

Music to the ears of seafood lovers. We're asking people to eat South Australian oysters and mussels and scallops. South Australians shucking shells by the seashore is part of an environmental project with the shells used to rebuild reefs which historically lined the coast. They were lost about a century ago and they haven't been able to come back naturally because we removed all the hard shell substrate that little baby oysters need to settle on to regrow reefs. After sunbaking for a year the shells are transferred into wire crates and placed on the sea floor where Mother Nature takes over. They are like the kidneys of the ocean so they filter the water, they create cleaner water, they also eat various types of algaes. A timely initiative as the state grapples a toxic algal bloom. Thousands of shells needed to construct 25 community reefs with collection bins now dotted around the state, benefiting both the environment and hospitality industry. Alone this weekend in our restaurant we've done over 60 dozen so hopefully we can fill up half of that bin. A new volunteer portal has also been set up for South Australians looking to go the extra mile with a number of programs including shellfish restorations open to the community. It's a great way for people to come together, get down to the beach, make memories, and support your local community and the local environment. Brianna Boylan, 10 News.
