The akoya pearl oyster, Pinctada imbricata has been fished for pearls for centuries and is amongst the widest spread of the pearl oyster species. Akoya oysters are found on areas of the eastern coastline of North and South America, the east coast of Africa, the Mediterranean, as well as throughout the Indo-Pacific. Most notably, the akoya oyster is found in Japan, where it has formed the basis of a billion-dollar pearling industry.
Recently a dramatic downturn in Japanese pearl production, resulting from a variety of factors including disease, has created an opportunity for NSW to enter the industry. The akoya oyster occurs naturally along much of the NSW coast including the Port Stephens area. In the early 1990’s, Barrier Pearls Pty. Ltd., in association with Japanese pearling interests, began investigating the possibility of establishing a temperate pearl oyster farming industry in NSW.
Barrier Pearls with the assistance of the Australian Museum located and surveyed populations of akoya oysters in NSW, which it believed could form the basis for a pearl farming industry. The Company approached NSW Fisheries to conduct the next phase of research, which was to evaluate survival, growth and nacre deposition in this species in NSW waters, primarily Port Stephens.
This research was considered consistent with the Department’s corporate vision to promote sustainable aquaculture industries and to develop commercial opportunities in aquaculture.
