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
Omega-3 fatty acids, appetite and growth in farmed fish. Australia has very limited wild fish supplies, and with the increasing realization of human health benefits of fish (i.e. omega-3 fatty acid) there is a need to increase availability through aquaculture. However, feeds used in aquaculture contain costly fish oil with limited global supplies. Attempts made to substitute fish oil with vegetable sources in aquaculture feeds have been mixed. This international, comparative and multidisciplinar ....Omega-3 fatty acids, appetite and growth in farmed fish. Australia has very limited wild fish supplies, and with the increasing realization of human health benefits of fish (i.e. omega-3 fatty acid) there is a need to increase availability through aquaculture. However, feeds used in aquaculture contain costly fish oil with limited global supplies. Attempts made to substitute fish oil with vegetable sources in aquaculture feeds have been mixed. This international, comparative and multidisciplinary project aims to reduce the dependence on fish oils through investigation of basic fatty acid metabolism and endocrinology on farmed fish to ensure that human health promoting characteristics in the final product are retained.Read moreRead less
C-type lectins and innate immunity in barramundi. The project aims to identify mannan binding lectins (MBL), key components of innate immunity, in barramundi and to develop quantitative assays for MBL. The project further aims to investigate the role of MBL in infectious processes of Streptococcus iniae, which causes disease in barramundi and humans. Quantitative assays will be used in conjunction with more traditional assays to evaluate the effect of supplemented feeds on the innate immune syst ....C-type lectins and innate immunity in barramundi.

Biodiversity loss on the Great Barrier Reef is a focus of public concern, with social cultural and economic ramifications. Adaptive and innovative management can reduce impacts on biodiversity. Reef HQ, the largest coral reef aquarium in the world, is a leader in coral reef education and conservation, but relies on wild-stock collections for exhibits. The key national benefit is the provision of critical information to facilitate the sustainable culture of marine invertebrates for use in public aquariums and the ornamental aquraium market thereby removing the reliance on wild collections. This is pivotal to reducing the overall pressure on coral reefs.Read moreRead less
The role of neurohormones in the regulation of appetite and successful sea water transfer in farmed Atlantic salmon. Cultured Atlantic salmon spend the first part of their life in freshwater and then following a physiological adaption phase called smoltification, the fish (now termed smolts) are transferred to sea cages for growout. A proportion of smolts fail to thrive after transfer, show slow or no growth and usually die some months later. This project will investigate the role that the neuro ....The role of neurohormones in the regulation of appetite and successful sea water transfer in farmed Atlantic salmon. Cultured Atlantic salmon spend the first part of their life in freshwater and then following a physiological adaption phase called smoltification, the fish (now termed smolts) are transferred to sea cages for growout. A proportion of smolts fail to thrive after transfer, show slow or no growth and usually die some months later. This project will investigate the role that the neurohomones that control both appetite and physiological stress in fish have in stimulating the resumption of feeding after sea water transfer.The basic knowledge generated will be used directly in development of strategies for minimising smolt failure in Atlantic salmon aquaculture.Read moreRead less

Barramundi fillet is one of the premier seafoods available in Australia and the decline of wild fisheries has increased the demand for the cultured product. Accordingly, there has been a rapid growth of the barramundi farming industry, but competition from cheaper overseas imports has cut the sale price and profit margins of local growers. By developing methods to increase growth rates, this research has the potential to substantially increase profit margins by reducing production costs and increasing turnover. Improvement of flesh quality will also increase the attractiveness of barramundi fillet. Increasing the viability of barramundi culture in Australia will attract more growers and increase employment opportunities.Read moreRead less
