Taura syndrome is a serious viral disease affecting giant tiger prawn (Penaeus monodon), northern white shrimp (Penaeus setiferus), blue shrimp (Penaeus stylirostris), and whiteleg shrimp (Penaeus vannamei). Outbreaks of the disease can cause up to 100% mortality in stocks.

More information on susceptible and vector species can be found here: GB Lists of susceptible and vector species.

Great Britain is free from Taura syndrome, and it is a listed (also referred to as notifiable) disease which you are legally obligated to report immediately to the Fish Health Inspectorate (FHI), Cefas. Fish Health Inspectorate - GOV.UK (www.gov.uk)

There has never been a recorded outbreak of Taura syndrome in the UK.

It does not affect humans.

How to spot Taura syndrome

Increased mortalities, especially in small juvenile shrimp.

Signs of the disease can include:

• shrimp moving towards the pond edge or surface
• pale reddish colouration
• tail fan red in colour
• soft shells
• an empty gut

How Taura syndrome is spread

Taura syndrome virus is spread through movements of and contact with infected shrimp, contaminated water or equipment.

Preventing and controlling Taura syndrome

There is no treatment for Taura syndrome.

Prevention is the best approach to disease control. You can protect your crustacea from serious diseases by being aware of the signs of Taura syndrome and other serious diseases and checking stock health regularly. Implement good husbandry and biosecurity practices.

Further information on biosecurity measures plans, guidance and templates can be found here: Biosecurity Measure Plans - Information and Templates - GOV.UK (www.gov.uk)

You must be sure any crustaceans introduced are Taura syndrome virus free. Do not buy crustacea of unknown origin. Follow the rules on moving aquatic animals: Aquatic animal health and movements guides - GOV.UK (www.gov.uk)

You must report it to the FHI immediately if you notice or become aware of crustaceans showing any of the signs of Taura syndrome. The FHI will investigate and apply disease control measures if required.
