Redefining the molecular mechanism underlying crustacean metamorphosis. This project uses the astonishing lifecycle of lobster larvae to better define the pathways and discover the key genes that regulate crustacean metamorphosis. Where, when, why and how metamorphosis occurs in crustaceans are important factors affecting fisheries recruitment and aquaculture production.

This project uses the astonishing lifecycle of lobster larvae to better define the pathways and discover the key genes that regulate crustacean metamorphosis. Where, when, why and how metamorphosis occurs in crustaceans are important factors affecting fisheries recruitment and aquaculture production. The project suggests that the current accepted paradigm for the molecular control of metamorphosis does not apply to lobsters and possibly other crustaceans where larval metamorphosis and the juvenile transformation are uncoupled. Using a unique supply of cultured lobsters and advanced molecular techniques, the project aims to develop tools to trigger and synchronise metamorphosis for use in aquaculture and invasive species management.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.

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
The link between environmental stress and disease onset in prawn aquaculture. The federal government has set a target for prawn aquaculture production to increase fourfold by 2010. A major barrier is disease: losses of 20% of production to viral diseases are not uncommon. To be internationally competitive, Australia needs to develop high health production systems. Most prawn stock carry chronic viral infections, but only exhibit disease symptoms following environmental stress. This project will ....The link between environmental stress and disease onset in prawn aquaculture. The federal government has set a target for prawn aquaculture production to increase fourfold by 2010. A major barrier is disease: losses of 20% of production to viral diseases are not uncommon. To be internationally competitive, Australia needs to develop high health production systems. Most prawn stock carry chronic viral infections, but only exhibit disease symptoms following environmental stress. This project will identify environmental stressors that activate viral disease in Penaeus monodon. Outcomes will be incorporated into on-farm managerial regimes to minimize risk of crop loss to disease. Development of biomarkers as indicators of stress related risks may be commercialized.Read moreRead less

Removing the impediment to large-scale selective breeding of Australian barramundi: deciphering and manipulating the genetic basis of sex change. This project will determine the genetic basis of sex control in barramundi and develop technologies to allow barramundi hatcheries to have increased control over reproduction leading to more efficient propagation and removing impediments to selective breeding.
Striking Gold - Determining the genetics of gold skin colour in barramundi. Barramundi is one of Australia’s finest eating table fish and the species is gaining global prominence. However, fillet flesh colour of Australian farmed barramundi exhibit greyish tones which lowers consumer acceptance compared to other white flesh fish and imported product. Barramundi with rare golden skin tones do not exhibit this flesh "greyness" and are therefore a valuable niche product to farm if they can be produ ....Striking Gold - Determining the genetics of gold skin colour in barramundi. Barramundi is one of Australia’s finest eating table fish and the species is gaining global prominence. However, fillet flesh colour of Australian farmed barramundi exhibit greyish tones which lowers consumer acceptance compared to other white flesh fish and imported product. Barramundi with rare golden skin tones do not exhibit this flesh "greyness" and are therefore a valuable niche product to farm if they can be produced in larger numbers. This project will elucidate the genetic basis and mechanism of expression behind the golden barramundi phenotype. In doing so, it will enable barramundi farmers to produce them at commercially relevant scales, providing them with a substantial competitive advantage in both domestic and global markets.Read moreRead less
