Quarantine of aquatic animals in Australia.

Australia is free from many significant diseases of aquatic animals. Quarantine policies for aquatic animals and aquatic animal products are designed to meet the international trade obligations of Australia, while preventing the entry of pests and diseases. These policies are supported by measures to prevent the introduction of aquatic species which would have deleterious effects on the environment. The Australian approach to quarantine--utilising objective risk analysis, where possible--is more difficult to apply to aquatic species than to terrestrial animals, as it is hard to identify and quantify risks when much of the relevant disease and epidemiological information is unavailable. Other than ornamental fish, for which stringent quarantine restrictions apply, involving isolation in quarantine premises, there have been no commercial importations of live aquatic species into Australia over the past decade. The onerous requirements for detailed analysis of disease risks and environmental implications have tended to deter potential importers. For many years, specific controls--based on risk analysis--have also been placed on the importation of products such as oysters in the shell, salmonid products, and feeds and meals of aquatic animal origin. A major review of quarantine requirements has been commissioned.
