DESCRIPTION OF ECOLOGICAL PROCESS FOR EXPERT ASSESSMENT
The health management of finfish, crustaceans and molluscs is an essential element of maintaining aquaculture productivity, fisheries resources and biodiversity in Australia.
This assessment provides information on the status and trends of national aquatic animal health, with respect to viral diseases, parasitic infestations and mass die-offs in the marine environment.
Australia has a reporting system for aquatic animal diseases of national significance. All the diseases currently reportable to the World Organisation for Animal Health (OIE) and other aquatic animal diseases of national significance are included on Australia’s National List of Reportable Diseases of Aquatic Animals (www.agriculture.gov.au/animal-plant-health/aquatic/reporting).
