The two current FRDC supported projects investigating the WA dhufish conducted at the Fremantle Maritime Center and the School of Biological Sciences at Murdoch University have identified various fish health issues for the species. In some cases these fish health issues will have implications for wild stocks of the WA dhufish and in others they may compromise the ability to commercialise the culture of the species.
Whilst health problems identified so far have been controlled to some extent in the hatchery, the ability to control these in a commercial grow-out operation will be very difficult unless a thorough understanding of the life history of the infesting organisms and the relationship to their host is known. Similarly, improved knowledge of the causal mechanisms of exophthalmia syndrome are required to permit prevention and treatment measures.
Staff at the Fremantle Maritime Centre, the Fisheries Department of WA, or the School of Biological Sciences at Murdoch University do not have the resources to quantify disease causal agents and preventative measures for the WA dhufish.
A recent report of the National Task Force on Imported Fish and Fish products (the Fish Task Force report) noted that there is a serious shortage of aquatic animal health specialists in Australia. The report identified a need to provide a continuum of expertise in this field to support developing aquaculture industries. A recent response to this issue from the Office of the Australian Chief Veterinary Officer (OCVO) emphasises that there is a considerable need for more veterinary training in fish health. This includes the development of standard diagnostic techniques for diseases of aquatic animals and the development of contingency plans for the management of aquatic disease and pest outbreaks. The proposed project addresses these issues.
