The Oyster Chronicle

Along the serene coast of South Australia, Franklin Harbour is a testament to the region’s commitment to sustainable aquaculture, particularly oyster farming.

Haslea ostrearia, a specific phytoplankton found in the ocean currents of South Australia, creates the green colouration of the oysters’ gills. This blue diatom produces a blue-green pigment called marennine, named after the Marennes-Oléron region in France, where it was first identified.

One of the critical regions for Pacific oyster cultivation in South Australia is Franklin Harbour. The mangrove sheltered waters of Franklin Harbour create a haven for oyster farming. The oysters here benefit from the abundance of phytoplankton, algae, shallow and warm waters, which imparts a unique flavour profile to the final product.
