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

Sea cage farming of warm water finfish is expanding worldwide, with potential for lucrative aquaculture industries. These, however, are threatened by monogenean (flatworm) parasites that weaken and can kill sea-caged fishes. Current control methods provide only short-term solutions and increase production costs. Monogeneans jeopardize the fledgling kingfish industry in South Australia and remain pests in Japanese yellowtail aquaculture (value, AUS$2.4 billion/year). With Australian and Japanese industry partners, our innovative field and laboratory approach will revolutionize management of fish parasites with direct life-cycles. Outcomes include: integrated long-term strategies to manage parasites; lower production costs; ability for new finfish industries to thrive.Read moreRead less

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
Reducing skeletal malformations in cultured marine fish using gene expression, improved nutrition and advanced system operation. Reducing malformations in farmed fish will benefit the Australian economy and society by providing greater quantities of cheaper, higher quality fish. Increased farmed fish production, currently worth ~$300 million p.a., will increase exports and decrease imports (currently ~50% of all Australian consumed fish). To benefit are the important regional farming operations ....Reducing skeletal malformations in cultured marine fish using gene expression, improved nutrition and advanced system operation. Reducing malformations in farmed fish will benefit the Australian economy and society by providing greater quantities of cheaper, higher quality fish. Increased farmed fish production, currently worth ~$300 million p.a., will increase exports and decrease imports (currently ~50% of all Australian consumed fish). To benefit are the important regional farming operations in QLD, NSW, SA, NT, TAS and WA. In particular, the largest industry in Tasmania will profit by having a viable new species to farm (striped trumpeter) reducing risk due to climate change and global oversupply of salmon. Another important benefactor will be the rapidly expanding yellowtail kingfish industry. 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
