The Australian pearling industry is based on the Pinctada maxima pearl oyster species. Since the mid-1950s the industry has focused on the production of cultured pearls. The first stage of culturing pearls requires fishing for wildstock pearl oysters, which are then used to manufacture cultured pearls through an aquaculture process.
