The World Organisation for Animal Health (WOAH) Aquatic Animal Health Code describes surveillance as “a systematic series of investigations of a given population of aquatic animals to detect the occurrence of disease for control purposes, which may involve testing samples of a population”.
Surveillance for aquatic animal disease is important for:
- early detection of disease
- demonstration of Australia’s disease status
- market access.
It also underpins many aquatic animal health management decisions on issues such as regional biosecurity, translocation, and assessing on-farm disease risks.
Types of surveillance
Types of surveillance according to the WOAH Aquatic Animal Health Code.
Passive surveillance (or general surveillance) is defined as observer-initiated animal health surveillance. It relies on observations of clinical or behavioural signs of disease, reporting those signs and investigation of an event.
Active surveillance activities are initiated by an investigator using a defined protocol and are generally conducted on a sector-specific basis with specific goals in mind.
Targeted surveillance is a sub-set of active surveillance where sampling and testing for a specific pathogen is planned and implemented.
National aquatic animal health surveillance strategy
Through AQUAPLAN 2022–2027, industry and governments identified a need for industry and government stakeholders in aquatic animal health to collaboratively develop a national surveillance strategy.
The national aquatic animal health surveillance strategy will:
- provide clarity on roles and responsibilities for national aquatic animal health surveillance
- articulate agreed principles for investment in the national surveillance system
- recognise the strengths of the existing surveillance system and provide a base from which improvements can be made
- provide a framework against which interested aquatic animal industry sectors can develop sector-specific surveillance plans, through AQUAPLAN 2022-2027 activity 3.2.
The final strategy is expected to be complete in early 2024. Progress on the strategy is available on the AQUAPLAN webpage.
Australia’s aquatic animal health reporting system
State and territory governments are responsible for managing aquatic animal diseases within their jurisdictions. They each have their own lists of reportable diseases of aquatic animals and legislative requirements in place for reporting the presence or suspicion of aquatic animal diseases.
State and territory lists are updated regularly to reflect the national list of reportable diseases of aquatic animals and the reporting requirements of the Australian Government Department of Agriculture, Fisheries and Forestry.
Visit your relevant state or territory government website for further information.
Australia’s national list of reportable diseases of aquatic animals provides a nationally agreed list of significant aquatic animal diseases that are reported on by state and territory governments to the Australian Government. The information is used to meet Australia’s international reporting requirements (e.g., to the World Organisation for Animal Health, WOAH) and to provide evidence of our disease-free status for many WOAH-listed diseases and other significant diseases.
For further information on Australia’s international reporting requirements and activities, see the International activities webpage.
To report concerns of potential aquatic emergency animal disease (EAD) events contact the Emergency Animal Disease Hotline on 1800 675 888.
Active and passive surveillance programs
The department coordinates activities to manage aquatic animal health nationally. This includes activities to enhance Australia’s aquatic animal health surveillance system. It does this in collaboration with industry and state and territory governments.

Abalone viral ganglioneuritis (AVG) caused by Haliotid herpesvirus-1 (HaHV-1) was first detected and reported in Australia on land-based abalone farms in Victoria in 2005 and later in live abalone in processing facilities in Tasmania in 2008.
To promote safe translocation of abalone between jurisdictions, the abalone health accreditation program (AHAP) was established in 2014 to enable the abalone aquaculture industry to demonstrate compartment freedom from infection with HaHV-1. The AHAP ensures that surveillance, biosecurity, auditing, and accreditation requirements are nationally consistent and transparent. The AHAP is also consistent with the compartmentalisation standards for infection with HaHV-1 described in the World Organisation for Animal Health Aquatic Animal Health Code.

Similar to the surveillance program for the abalone sectors, a structured surveillance program for Australian barramundi hatcheries was agreed by the barramundi aquaculture industry. The surveillance plan included two exotic disease agents (infectious spleen and kidney necrosis virus group of megalocytiviruses and scale drop disease virus) and an endemic disease of trade significance (nervous necrosis virus). The inter-laboratory comparison program has also been successfully completed.

This project aimed to improve Australia’s active surveillance capability for exotic and endemic diseases of market access importance. Australia’s wild and farmed abalone sectors agreed to participate in this nationally coordinated active surveillance project.
Haliotid herpesvirus-1 (HaHV-1; present in Australia) and Perkinsus species (some species are present in Australia but P. marinus is exotic to Australia) were tested for in abalone from participating farms and wild abalone fisheries, and Xenohaliotis californiensis (exotic to Australia) was tested for in abalone from participating farms. HaHV-1 and X. californiensis were not detected in any farmed and wild samples. P. marinus was not detected, however some endemic species of Perkinsus were detected in animals from known infected areas.
The project has significantly improved national surveillance and diagnostic capabilities through designing nationally consistent sampling strategies and implementing inter-laboratory comparison programs among participating national and state government laboratories for 2 pathogens that are present in some areas of Australia.

The structured surveillance program for the Australian tropical freshwater ornamental fish production sector tested a group of exotic disease agents, megalocytiviruses, in the susceptible species (cichlids, gourami and poecillid fish) that were produced at licensed facilities in Australia. It was concluded that domestic farmed fish populations of either cichlid, gourami and poecillid fish families from four Australian jurisdictions (n=546) were free from megalocytiviruses.

White spot disease was first detected in Australia in farmed prawns on the Logan River, Southeast Queensland in 2016. It was later detected in wild populations of crustaceans, such as prawns and crabs, in the northern part of Moreton Bay in 2017. In response to the outbreak, a nationally coordinated surveillance program for white spot syndrome virus (WSSV) was commenced in November 2017. The objective of the national surveillance program was to demonstrate national freedom, or alternatively, zone freedom from WSSV based on the criteria set by the international standards. This surveillance demonstrated WSSV freedom for all areas of Australia, apart from a small zone in southeast Queensland.
For further information on the white spot disease outbreak visit the Disease incidents webpage and outbreak.gov.au.
