Aquatic Animal Health Subprogram: Strategic approaches to identifying pathogens of quarantine concern associated with the importation of ornamental fish

Funded Activity Summary

Nearly 18 million ornamental fish are imported annually under a policy based on an Import Risk Analysis published in 1999. Despite the biosecurity measures in place since 2000, there have been several incidents of exotic pathogens from ornamental fish affecting wild and farmed fish populations. These include atypical Aeromonas salmonicida, cyprinid herpesvirus 2 (CyHV2) and dwarf gourami iridovirues (DGIV). There is a need to acquire new knowledge to support policy reform as the ornamental fish industry advances and new pathogens emerge.
Project FRDC 2009/044: AAH: surveys of ornamental fish for pathogens of quarantine significance determined that ornamental fish with subclinical infections of exotic viruses were passing through quarantine undetected. This project provided scientific evidence that led Biosecurity Australia to relax the import conditions for goldfish as CyHV2 is now considered endemic. Also, DGIV was detected in all consignments of imported gouramis at an average prevalence of 19%. DGIV was detected in domestic fish populations at wholesale and retail premises and at one ornamental aquaculture facility. The project outcomes indicated that pre-export biosecurity measures (and associated health certification provided by exporting country authorities) and post-arrival quarantining of fish in Australia were insufficient to detect and prevent fish with subclinical infections of exotic pathogens from entering Australia.

There is little information available on other viral, bacterial and parasitic disease agents carried by imported ornamental fish. Specifically, there is a paucity of information available on parasites of imported fish and their potential risk to Australian industries and ecosystems. There is a need to determine whether pathogens of biosecurity significance associated with ornamental fish are entering Australia despite the import conditions.

Objectives:
1. Determine if pathogens of potential biosecurity concern on the national list are entering QAPs in Australia through the trade in ornamental fish
2. Determine if current import conditions for goldfish requiring freedom from specific pathogens are being met
3. Document parasites of potential biosecurity concern that are associated with imported ornamental fish
4. Develop efficient pooled sample strategies for testing imported fish
