Developing akoya pearl culture on the Australian east coast, challenges and constraints.
Abstract Developing aquaculture in increasingly urbanized societies poses significant challenges. An example has been the recent attempt to establish a pearl industry in the sub-tropical waters of New South Wales (NSW) on the Australian east coast. NSW is Australia's most populous state with the vast majority of the population and development occurring along its coast. This development has led to conflict over land and water use. In 1993, interest began in developing a marine pearl industry using the native pearl oyster Pinctada imbricata. The NSW Government was approached and research was undertaken to establish the status of the P. imbricata population in NSW, its amenity to culture, its capacity to produce high quality pearls and the likely impacts that a pearl industry might have. In 2001 the first application to establish a 92 ha commercial farm was made, which met with considerable local public opposition. Concerns regarding the social, economic and environmental impact were raised and the government responded by establishing an independent Commission of Inquiry. While the Commission recommended that, with certain constraints, the farm could proceed, the government ultimately overturned the decision citing environmental concerns and refused the development application. A subsequent, significantly altered application was lodged in late 2003, but this application also met with local opposition and was similarly refused in mid-2004. Despite research confirming the environmentally benign nature of the proposal and the confirmation of economic viability, the failure to initially effectively allay public concerns ultimately prevented the acceptance these two applications. The future of a pearl industry in NSW is now unclear.
