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...

The feasibility of enhancing and rehabilitating abalone stocks by larval re-seeding

The decline of many of the world's fisheries has stimulated interest in the enhancement of stocks by using cultured animals. Enhancement of abalone stocks with cultured Juveniles has been practiced for some time (in Japan in particular), but the high cost of rearing juveniles or the high mortality...
