TSGA IPA: The Australian Aquatic Animal Health and Vaccine Centre: First Phase to Establish Atlantic Salmon Biosecure Fish Facility Capabilities and Develop Strategy for an Australian Centre of Excellence
TSGA IPA: Establishing viral diagnostics for salmonid aquaculture in Tasmania: characterisation and identification of Salmon Orthomyxo-like virus (SOMV) and associated pathology in Atlantic Salmon
Atlantic Salmon Aquaculture Subprogram: assessment of Orthomyxo-like virus pathogenicity in Atlantic salmon
Key Stakeholder Relevance
Since the inception of marine salmonid aquaculture in Tasmania during the 1980’s, a number of pathogens have emerged. The industry and DPIPWE have collaborated in developing/commercialising vaccines for several of these pathogens. This successful, ongoing strategy is used to mitigate disease in a practical, cost-effective and sustainable manner. These vaccines are effective however for known pathogens; the emergence of new pathogens presents the industry with an entirely new set of challenges. Viral pathogens, such as the Orthomyxo-like virus, are of particular concern to industry as there are no therapeutic agents available to treat virally-infected fish. This project was instigated on behalf of the Tasmanian salmon growers and the project aims to inform the salmonid aquaculture industry and government as to the potential for the virus to cause disease in Atlantic salmon.
Emerging Diseases: Data Provides Context
Little is known about the Orthomyxo-like virus associated with farmed Atlantic salmon. Investigation/analysis is hampered by a lack of information about the pathogenic capability of the Orthomyxo-like virus and limited histopathology description Orthomyxo-like virus infected fish. The proposed pathogenicity trial will determine if the Orthomyxo-like virus can act as a primary pathogen of Atlantic salmon in the absence of confounding external stressors. If the virus is shown to be pathogenic it will provide context for industry & government stakeholders to develop management, control and surveillance strategies.
