Pacific Oyster Mortality Syndrome (POMS), the disease caused by OsHV-1 microvariant, results in high and rapid mortality in Pacific Oysters (Crassostrea gigas) and has been responsible for significant economic loss to oyster industries in Australia and around the world. The diversification of commercial production into different oyster species (Native Oysters and Rock Oysters), that are not susceptible to POMS, has been proposed as a way to mitigate the risk of POMS in southern Australia. However, the Australia Native Oyster (Ostrea angasi) industry is still in its infancy, with knowledge gaps along the production chain. Additionally, there are no wild populations of Rock Oysters (Saccostrea sp.) in South Australia. Despite Rock Oyster aquaculture being well established in New South Wales and recently in Western Australia they have never been commercially produced in South er Australia and translocation policies to move them around the state are non-existent. This project aimed to improve on-farm production of Native Oysters and determine if Rock Oysters can be safely translocated to South Australia from Western Australia, to help Australian oyster growers to diversify into these species.
