White spot disease (WSD) is an internationally notifiable disease of crustaceans caused by White Spot Syndrome Virus (WSSV). On 22nd November 2016 a WSSV incursion was first reported in Black Tiger Prawns (Penaeus monodon) cultured on a prawn farm (1IP) taking water from the Logan River, SE QLD.

In response to the WSD outbreak FRDC quickly implemented the follow

ing projects to support the prawn farming industry and provide clear direction towards planning for future recovery for affected farms and fisheries; and protecting the biosecurity of areas away from the Logan River control zone.

Current Research

Status – Completed.
Assessing compliance and efficacy of import conditions for green (raw) prawn in relation to White Spot Syndrome Virus (WSSV).
Status – Near completion. Awaiting finalisation.
Economic Impact of 2016 White Spot Disease Outbreak.
Status – Near completion. Near final data based upon information provided by affected farmers and fishers provided to Ridge Partners.
White Spot Syndrome Virus (WSSV) preparedness for biosecurity awareness and adoption of best practice by the NSW and QLD wild catch commercial fishers - understanding what extension pathways work best.
Status – Commenced.


Past Research

​2011-259 Seafood Incident Response Plan 2012
Aquatic Animal Health Subprogram: enhancement of emergency disease management through the education and training of the CCEAD participants on the CCEAD process
Aquatic Animal Health Subprogram: production of an AQUAVETPLAN disease strategy manual for white spot disease of all WSV-susceptible crustaceans
White spot in prawns


Future Research Needs 

It is likely that FRDC will need to support a range of WSD R&D projects in future as immediate, medium and longer term priorities are identified through current project activities and ongoing consultation between industry, national and international aquatic disease experts and government R&D and biosecurity agencies. 



White spot disease does not pose a threat to human health or food safety.



What is white spot disease?

White spot disease (WSD) is a highly contagious viral disease of decapod crustaceans including prawns, crabs, yabbies and lobsters. White spot disease is caused by white spot syndrome virus (WSSV).

Where is white spot disease found?

WSD is widespread throughout prawn farming regions in Asia and has become established in prawns farmed in the Americas where it has caused severe losses.

How is white spot disease spread?

The disease is primarily spread through the movement of infected animals or water. Birds feeding on infected animals can contribute to the spread of the disease.

Can fish spread the virus?

No. Fish are not carriers of the virus that causes WSD.

What does white spot disease look like?

Prawns with WSD may have a loose shell with numerous white spots (0.5-2.0mm in diameter) on the inside surface of the shell and a pink to red discolouration.

How to report white spot disease

It is crucial that all aquaculture operators, commercial and recreational fishers and other waterway users report unusual signs in prawns (including bait) and other crustaceans.

Early detection provides a better chance of being able to contain and eradicate this serious disease.

If you see crustaceans that you suspect have the disease it is important to take note of the location and time and report this information immediately to Biosecurity Queensland on 13 25 23.

Alternatively phone the Emergency Animal Disease Watch Hotline on 1800 675 888 from anywhere in Australia.
