Training is needed, for fish farmers, technicians & veterinarians in all Australian States, for increased vigilance with respect to early disease detection, diagnosis, control and eradication of newly emerging endemic and exotic fish diseases. Northern States of Australia (NT, Qld) are at greatest risk for disease incursions, via the vast expanse of the States & Territories, remoteness of farms, illegal trade of fish, fish products, shipping movements (over 13 ports in Qld), people movement and the proximity of northern Australia to Indonesia, PNG and Asia. Early fish disease detection and eradication is necessary to protect the Biosecurity of the Australian Fish Farming industry, and prevent disease spread within and between States.

The continued annual growth of the barramundi & freshwater fish industries in all Australian States precipitates the need for farmer training for disease detection at the grass-roots level for farm workers to detect, control and treat fish disease, and thereby reducing disease risk to aquaculture enterprises and fisheries resources.

A specific training workshop is needed to train fish farmers, technicians, fisheries officers, vets, with hands-on, practical, technical skills & knowledge by Aquatic Animal health Professionals, so skills can be practically applied on farms during disease epizootics, investigations, and disease emergencies. This is needed to support continued growth, productivity, & sustainability of the Australian Fish farming Industry, disease being a limiting factor. This Workshop is needed to support on-going disease reporting activities by all States to DAFF, OIE and NACA, allowing continuation of Australian trade in fish and disease-free status.

Australian prawn production at around 22 kilotonnes is valued in excess of $250 million. Clearly, the prawn fishery is an important natural resource for Australia that is also the basis for a significant export industry. In addition, prawn aquaculture is a significant industry in northern Australia and accounts for around 14% of the total volume of Australian prawn production. Infectious myonecrosis is a viral disease that has caused significant disease outbreaks and mortalities in farmed Penaeus vannamei in Brazil and South-East Asia, including Indonesia. While P. vannamei is considered the principal host, experimental infection of P. stylirostris (Pacific blue shrimp) and P. monodon (black tiger shrimp) has been reported. The susceptibility of other shrimp/prawn species is unknown. Information on the susceptibility of prawn species important to Australia, including banana prawns (Fenneropenaeus merguiensis), brown tiger prawns (P. esculentus) is lacking. This project would provide information on the susceptibility of two important species of Australian prawns to exotic IMNV. Such information is important to policy-makers, regulators and primary producers with respect to relevant biosecurity issues at all levels of government.
