Fish flukes (flatworm parasites) with direct lifecycles can weaken and kill captive fish and threaten lucrative industries like finfish aquaculture and public aquaria in Australia and globally. Traditional approaches and molecular techniques will identify monogenean flukes in a family containing known pathogenic species distributed worldwide. Knowledge of fish disease is paramount for quarantine, risk assessments for import/export and for managing pathogen outbreaks in aquaculture. Benefits include: economic/social improvements in regional/rural Australia where fish farms are expanding; international excellence and core research training in fish parasitology; profitable, exportable expertise; knowledge of endemic and shared pathogens.Read moreRead less

Ecological impacts of QX Oyster disease and its management strategies. QX disease is responsible for mass mortality of oysters, and, as a result, economic and job losses. QX disease also threatens ecosystem services provided by wild oysters, such as biodiversity enhancement and fish production. This project will provide estuarine managers with information about how proposed QX management solutions will impact wild oyster populations and vital ecosystem services. It will also contribute to traini ....Ecological impacts of QX Oyster disease and its management strategies. QX disease is responsible for mass mortality of oysters, and, as a result, economic and job losses. QX disease also threatens ecosystem services provided by wild oysters, such as biodiversity enhancement and fish production. This project will provide estuarine managers with information about how proposed QX management solutions will impact wild oyster populations and vital ecosystem services. It will also contribute to training of early career researchers in strategies to ensure the sustainable use of Australia's biodiversity. As QX outbreaks appear to be increasing, this research and training is urgently needed to underpin management to ensure long-term sustainability of valuable estuarine resources.Read moreRead less

This project will provide a first nationwide survey of commercially important crustacean stocks enabling the Australian fisheries authorities to assess the full scale ....Investigations of Australian Hematodinium species (sp.): a dinoflagellate parasite damaging major crustacean fisheries in Australia and worldwide. The dinoflagellate Hematodinium species (sp.) causes a deadly infection in crustaceans worldwide and a recent outbreak in Shark Bay, WA highlights its importance in Australian waters. This project will provide a first nationwide survey of commercially important crustacean stocks enabling the Australian fisheries authorities to assess the full scale of the problem. Also, we will develop a simple, easy-to-use tool for diagnosis and management of Hematodinium sp. This project will expand the diversity of parasites studied in Australia by including this relatively poorly studied but damaging group. This project will also foster interdisciplinary collaborations within Australia, and internationally.Read moreRead less
QX DISEASE RESISTANCE IN SYDNEY ROCK OYSTERS. QX is a fatal disease of Sydney rock oysters. The protozoan parasite that causes QX has been identified in more than one third of oyster farming areas on the east coast of Australia. Disease outbreaks have already destroyed the oyster industry in some of those areas. This project tests whether a novel form of defensive protein that has been identified in some oysters can be used as a genetic marker of QX disease resistance. The selective breeding of ....QX DISEASE RESISTANCE IN SYDNEY ROCK OYSTERS. QX is a fatal disease of Sydney rock oysters. The protozoan parasite that causes QX has been identified in more than one third of oyster farming areas on the east coast of Australia. Disease outbreaks have already destroyed the oyster industry in some of those areas. This project tests whether a novel form of defensive protein that has been identified in some oysters can be used as a genetic marker of QX disease resistance. The selective breeding of disease resistant oysters based on such a genetic marker would help to control QX and secure the future of Australia's rock oyster industry.Read moreRead less
