A Quantitative Analysis of Prawn Harvesting Strategies. Prawn fisheries in NSW are undergoing major changes in their management. This unusual PhD project will design and test new decision-rules and strategies for fishery managers that are based upon pragmatic quantities of catch-per-unit-effort, prawn size, and river temperature and discharge. The performance of rules and strategies will be measured to ensure that they generate satisfactory outcomes for the prawn resources and the people that de ....A Quantitative Analysis of Prawn Harvesting Strategies. Prawn fisheries in NSW are undergoing major changes in their management. This unusual PhD project will design and test new decision-rules and strategies for fishery managers that are based upon pragmatic quantities of catch-per-unit-effort, prawn size, and river temperature and discharge. The performance of rules and strategies will be measured to ensure that they generate satisfactory outcomes for the prawn resources and the people that depend upon them. A major outcome will be precautionary or risk-averse decision-rules and strategies that are robust to the uncertainties that exist in prawn fisheries.Read moreRead less
Design and Development of DNA Oligonucleotide Microarrays (Biochips) for Fish Species Identification From Processed Food Products. Australia's seafood industry (valued at A$2 billion/annum) imports and exports a wide variety of fish and shellfish products.

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 research program will enable Australia to sustainably use key marine resources by modelling and developing management strategies for tuna and billfish of the Pacific and Indian Oceans. The interdisciplinary research program will (1) develop a set of hypotheses about the critical variables and positive and negative feedbacks of highly migratory fish stocks, (2) model the ecological and economic systems of tuna and billfish in the Pacific and Indian Oceans and (3), link the models to a framework to adaptively manage the resources in a multilateral context while ensuring their long-term sustainability.Read moreRead less
Native fish stocking of rivers: discriminating between hatchery-reared and wild fish. Stocking of fish is widely used in attempts to restore native fish populations. Little is known of the fate of stocked fish or the effects of stocking on resident populations. We will develop and evaluate protocols for chemical marking of otoliths of hatchery-reared fish so that their source can be determined. Experimental stocking of hatchery-reared fish will be undertaken and population structure and sourc ....Native fish stocking of rivers: discriminating between hatchery-reared and wild fish. Stocking of fish is widely used in attempts to restore native fish populations. Little is known of the fate of stocked fish or the effects of stocking on resident populations. We will develop and evaluate protocols for chemical marking of otoliths of hatchery-reared fish so that their source can be determined. Experimental stocking of hatchery-reared fish will be undertaken and population structure and source of stocked versus wild fish determined in stocked and unstocked rivers. Natural chemical signatures will also help determine important recruitment areas. The outcomes will allow fisheries managers to make informed decisions regarding stocking strategies.Read moreRead less
Establishing an ecological basis for stocking density of Australian bass in freshwaters: Experimental field tests of a general numerical model. Large numbers of the Australian public go fishing, particularly in rivers and impoundments. Angling in these waterways provides a strong source of income for rural and regional communities. The stocking of native fish to support inland angling also sustains much of the aquaculture industry in western NSW and Queensland. This study will develop an optimal ....Establishing an ecological basis for stocking density of Australian bass in freshwaters: Experimental field tests of a general numerical model. Large numbers of the Australian public go fishing, particularly in rivers and impoundments. Angling in these waterways provides a strong source of income for rural and regional communities. The stocking of native fish to support inland angling also sustains much of the aquaculture industry in western NSW and Queensland. This study will develop an optimal approach to stocking Australian bass which is relevant for other stocked freshwater species, and will allow stocking to be undertaken in an environmentally responsible manner. This will both enhance the outcome of investment of public funds in stocking, and enhance the recreational fishing experience that is so important to rural regional communities.Read moreRead less

An innovative technique of micro-emulsion of vegetable oils and water has been developed to create a new generation, low-toxicity drilling fluids for use by the petroleum exploration industry. The project aims at investigating the chronic toxicity of new generation drilling fluids to fish, and re-formulate the drilling fluids to minimize the toxic ingredients. Biomarkers of exposure and effects such as, but not limited to, EROD induction, DNA damage and stress proteins will be explored in fish exposed chronically to drilling fluids or their ingredients. Outcomes include environmentally acceptable drilling fluids, and will represent the start point for multi-million dollars agriculture and manufacturing industry in Australia.Read moreRead less

A genetic and experimental assessment of the frequency and importance of hybridisation of Black and Yellow Fin Bream. Bream (Acanthopagrus spp.) species underpin several valuable and heavily exploited fisheries in eastern Australia, but the two principal species, yellowfin (A. australis) and black (A, butcheri), interbreed significantly. This hybridisation is poorly documented and, with increasing harvests, could lead to long-term economic impacts and severe repercussions on biodiversity. It cou ....A genetic and experimental assessment of the frequency and importance of hybridisation of Black and Yellow Fin Bream. Bream (Acanthopagrus spp.) species underpin several valuable and heavily exploited fisheries in eastern Australia, but the two principal species, yellowfin (A. australis) and black (A, butcheri), interbreed significantly. This hybridisation is poorly documented and, with increasing harvests, could lead to long-term economic impacts and severe repercussions on biodiversity. It could, for example, increase the risk of localised extinctions and impact on genetic diversity of both species. We will use an innovative combination of molecular genetics and breeding experiments to: (i) determine frequency and direction of hybridisation; (ii) infer strength of genetic connections among estuaries; and, (iii) explore implications for sustainable fisheries management.Read moreRead less
Stocking of fish and prawns at ecologically determined densities into Australian estuaries. Increasing numbers of people like to go fishing, and to catch a fish, which translates into tourism income and aquaculture business. Restocking is a fisheries management option when the natural supply or survival of larvae is limited. This study will determine for the first time the ecologically appropriate abundance of small mulloway and prawns that an estuary can sustain. We will assess the extra eff ....Stocking of fish and prawns at ecologically determined densities into Australian estuaries. Increasing numbers of people like to go fishing, and to catch a fish, which translates into tourism income and aquaculture business. Restocking is a fisheries management option when the natural supply or survival of larvae is limited. This study will determine for the first time the ecologically appropriate abundance of small mulloway and prawns that an estuary can sustain. We will assess the extra effort needed to release larvae into particular key habitats, and develop new technologies to identify our larvae from the wild. Our findings will be relevant to restocking of Australia's inland rivers, which at present has little ecological basis.Read moreRead less
Influence of Marine Protected Areas on ecosystem resilience and ecological processes. Australia is implementing a national representative system of marine protected areas (MPAs). The aims of the MPAs include ensuring ecological viability, maintaining ecological processes, and protecting biodiversity. The ability of MPAs to achieve these aims, however, is based largely on theory rather than empirical evidence. Implementation of MPAs is often controversial as it may cause economic hardship to comm ....Influence of Marine Protected Areas on ecosystem resilience and ecological processes. Australia is implementing a national representative system of marine protected areas (MPAs). The aims of the MPAs include ensuring ecological viability, maintaining ecological processes, and protecting biodiversity. The ability of MPAs to achieve these aims, however, is based largely on theory rather than empirical evidence. Implementation of MPAs is often controversial as it may cause economic hardship to communities dependent on fishing. Our project will benefit environmental managers by determining if and how MPAs influence biodiversity, ecological processes, and ecosystem services and resilience. It will benefit the wider community by providing the rigorous scientific evidence in favour of MPAs that is demanded by stakeholders.Read moreRead less
