Hepatopancreatitis Reported on Australian Prawn Farm

08 February 2016

AUSTRALIA - Two outbreaks of hepatopancreatitis have been reported on prawn farms in Queensland.

The affected tiger prawns were farmed in a semi-closed systems in Bundaberg and Cardwell, which are both located on Queensland's coast.

Morbidity and mortality on both farms were recorded at 3 on a scale of 0 to 5.

Affected animals ranged from 35 to 95 days post stocking.

The histopathology of the hepatopancreas in affected animals is consistent with that described for acute hepatopancreatic necrosis disease (AHPND). However, the disease does not meet the case definition for AHPND provided in the draft OIE Aquatic Code chapter.
