The strong and growing worldwide demand for a range of lobster products cannot be fulfilled by existing wild fisheries. Only the sustainable production of lobsters using hatchery seedstock will satisfy the needs of aquaculture and the possibility of enhancing and reseeding the fishery. Lobster aquaculture will provide a new high-value industry for coastal rural Australia, especially in areas with existing fishing and aquaculture enterprises. This project will develop new technologies to address the challenging target of producing commercial quantities of juvenile lobsters for aquaculture and enhancement.Read moreRead less
Predictive ichthyotoxicity, diagnostics and risk assessment of harmful algal blooms impacting on the Tasmanian salmonid aquaculture industry. We aim to define through a combination of laboratory culture exposure and live cage bioassay experiments the minimum cell concentrations of harmful microalgae (Karenia, Heterosigma, Noctiluca, Chaetoceros) that can cause salmonid mortalities or are a factor in compromising fish health or reducing fish farm productivity.

We aim to define through a combination of laboratory culture exposure and live cage bioassay experiments the minimum cell concentrations of harmful microalgae (Karenia, Heterosigma, Noctiluca, Chaetoceros) that can cause salmonid mortalities or are a factor in compromising fish health or reducing fish farm productivity. The diagnostic pathology and fish behaviour caused by different harmful algal taxa will be carefully documented to assist fish health inspectors in the routine diagnosis of algal toxicosis ot compromised fish health. Ultimately, this information will be integrated into a risk assessment strategy for the Tasmanian salmonid industry to manage fish stocks during times of harmful algal bloom events.Read moreRead less

The network will facilitate inderdisciplinary and collaborative research into the limitations on microalgal growth leading to the development of new, commercial-scale microalgae culture systems, the production of fine chemicals, bioactive compounds and renewable fuels (hydrogen), as well as environmental applications such as monitoring the physiological state of phytoplankton in the environment, CO2 bioremediation and algal/bacterial systems for the bioremediation of contaminated soils. This will be achieved by applying research on photosynthetic light utilisation efficiency and carbon fixation, chlorophyll fluorescence, biochemistry of secondary metabolites, molecular biology and photobioreactor design and engineering, informed by an understanding of the ecology of these algae.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
Feeding and digestion in tropical rock lobster phyllosoma larvae and its applications for culture. Provision of larval culture diets that provide optimal nutrition in a suitable presentation format is the major challenge for developing a rock lobster aquaculture industry.

Provision of larval culture diets that provide optimal nutrition in a suitable presentation format is the major challenge for developing a rock lobster aquaculture industry. Tropical rock lobsters are likely contenders due to their faster growth rates and shorter larval phase than temperate species. This project will assess the ingestive and digestive capabilities of larvae during development, through an examination of mouthpart and gut structure and their types and concentration of digestive enzymes. Information will be used to formulate and test improved diets of appropriate size, texture and nutritional composition and will be the first comprehensive analysis of preferred larval diets on the basis of their biological and physiological characteristics.Read moreRead less

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
