Australia's seafood industry (valued at A$2 billion/annum) imports and exports a wide variety of fish and shellfish products. This industry is open to exploitation, specifically in respect of product labelling. A rapid and reliable method for identifying commercial and endangered fish species in seafood products is urgently needed for effective management and regulation of the industry. New genetic biochip technology enables any species or strains of an organism to be rapidly, and accurately, identified by non-experts. In collaboration with GeneScan Australia, this project applies this new technology to develop a diagnostic tool for checking the labelling of Australian seafood products.Read moreRead less

The project will also establish Australia at the forefront of biotechnological research and its applications to aquaculture.Read moreRead less
Towards selective breeding of pearl oysters - quantitative and population genetics of the silver-lipped pearl oyster Pinctada maxima. Successful selective breeding programs rely on two critical factors; i) an understanding of the genetic processes underpinning phenotypic expression of commercially important traits and ii) a reliable method to retain pedigrees so that the rate of inbreeding can be controlled. This project will utilise modern quantitative and molecular genetic approaches to genera ....Towards selective breeding of pearl oysters - quantitative and population genetics of the silver-lipped pearl oyster Pinctada maxima. Successful selective breeding programs rely on two critical factors; i) an understanding of the genetic processes underpinning phenotypic expression of commercially important traits and ii) a reliable method to retain pedigrees so that the rate of inbreeding can be controlled. This project will utilise modern quantitative and molecular genetic approaches to generate for the first time fundamental information on the role genetics has on growth and pearl quality traits in the silver-lipped pearl oyster Pinctada maxima. Outcomes from this project when integrated into a selective breeding program for this species will dramatically transform the international competitiveness of this valuable industry.Read moreRead less
Linking genes with the phenotype - creation of a genetic linkage map for the silver-lipped pearl oyster Pinctada maxima. R&D undertaken in this project will increase our fundamental understanding of the role genetics plays in production of a premium quality cultured South Sea pearl. When utilised in future selective breeding programs aimed at improving pearl quality traits the information generated will allow Australian pearling companies to be more productive and to maintain a competitive advan ....Linking genes with the phenotype - creation of a genetic linkage map for the silver-lipped pearl oyster Pinctada maxima. R&D undertaken in this project will increase our fundamental understanding of the role genetics plays in production of a premium quality cultured South Sea pearl. When utilised in future selective breeding programs aimed at improving pearl quality traits the information generated will allow Australian pearling companies to be more productive and to maintain a competitive advantage over their rivals. Many rural communities are dependent on pearling companies for their economic prosperity and community identity. Consequently, positive growth of the pearl industry as a result of the proposed R&D will greatly benefit the economic and social wealth of these rural populations.Read moreRead less
QX DISEASE RESISTANCE IN SYDNEY ROCK OYSTERS. QX is a fatal disease of Sydney rock oysters. The protozoan parasite that causes QX has been identified in more than one third of oyster farming areas on the east coast of Australia. Disease outbreaks have already destroyed the oyster industry in some of those areas. This project tests whether a novel form of defensive protein that has been identified in some oysters can be used as a genetic marker of QX disease resistance. The selective breeding of ....QX DISEASE RESISTANCE IN SYDNEY ROCK OYSTERS. QX is a fatal disease of Sydney rock oysters. The protozoan parasite that causes QX has been identified in more than one third of oyster farming areas on the east coast of Australia. Disease outbreaks have already destroyed the oyster industry in some of those areas. This project tests whether a novel form of defensive protein that has been identified in some oysters can be used as a genetic marker of QX disease resistance. The selective breeding of disease resistant oysters based on such a genetic marker would help to control QX and secure the future of Australia's rock oyster industry.Read moreRead less
Natriuretic peptide hormones and the stress response of fish. There are two main benefits of our research to Australia. Firstly, the team that we have assembled have international reputations, and include scientists from overseas. This team will be led by Australian Institutions and will put Australian science in the forefront of a competitive field, internationally. Secondly, our research examines questions that are critical in our understanding of how animals respond to stressful events. T ....Natriuretic peptide hormones and the stress response of fish. There are two main benefits of our research to Australia. Firstly, the team that we have assembled have international reputations, and include scientists from overseas. This team will be led by Australian Institutions and will put Australian science in the forefront of a competitive field, internationally. Secondly, our research examines questions that are critical in our understanding of how animals respond to stressful events. The response to stress, if excessive, leads to ill-health in both humans and other animals. Our research examines new connections between stress and fish biology, which could lead to discoveries that are valuable in managing stress and health in wild and farmed fishes.Read moreRead less

Capture stress and post-capture survival of sharks and other chondrichthyans in fisheries bycatch. Australia is adopting ecosystem approaches to fisheries management. However, to embrace such an approach there is an urgent need for better information on the biology, ecology and population dynamics of sharks, rays and chimaeras (class Chondrichthyes). Chondrichthyan species are among the most sensitive in their response to the effects of fishing. Results from the present proposal will contribute ....Capture stress and post-capture survival of sharks and other chondrichthyans in fisheries bycatch. Australia is adopting ecosystem approaches to fisheries management. However, to embrace such an approach there is an urgent need for better information on the biology, ecology and population dynamics of sharks, rays and chimaeras (class Chondrichthyes). Chondrichthyan species are among the most sensitive in their response to the effects of fishing. Results from the present proposal will contribute to determining mortality of chondrichthyan bycatch species in response to the effects of capture in fishing gear, handling by fishers and discarding at sea. The work will contribute to biodiversity conservation and maintenance of ecosystem structure and function for present and future generations.Read moreRead less
