Growth of pearl oysters in the southern and northern areas of the pearl oyster fishery and examination of environmental influences on recruitment to the pearl oyster stock

The pearling industry is Australia’s most valuable aquaculture industry, generating approximately $187 million in 1997 (source: ABARE 1997). The oysters used to culture pearls are derived almost entirely from wild stock shell, rather than hatchery produced stock as occurs in other major...

Research and development of hatchery and nursery culture for the pearl oyster, Pinctada maxima

The Western Australian Pearling Industry is totally reliant on quotas of wild stock silver- or goldlip pearl oysters, Pinctada maxima. Any sustainable expansion of the Industry is unlikely to occur unless hatchery-propagated oysters become available as an alternative source to wild stock....
