Outcomes of emergency consultation on shrimp early mortality syndrome / AHPNS

Audio recordings of the technical presentations from the consultation are available for download and streaming. A disease card is in preparation to assist with field level diagnosis and will be made available shortly, followed by the full report of the consultation – Ed.

An emergency regional consultation on "Early Mortality Syndrome" of shrimp, or Acute Hepatopancreatic Necrosis Syndrome, concluded on Friday 10 August 2012 in Bangkok, Thailand. The consultation brought together over 87 participants including international shrimp health experts, regional governments and industry to share information on this emerging disease, its occurrence, pathology and diagnosis, and to develop a coordinated regional response to the issue. The consultation was jointly organised by NACA and the Australian Department of Agriculture, Fisheries and Forestry.

Early mortality syndrome or AHPNS?

Heavy mortalities during the early stages of a shrimp crop are not unusual and there are a variety of management and pathogen related factors that can cause such losses, which are often described by the catch-all term "early mortality syndrome". However, in 2010 a new and distinctive pattern of mortalities began to be noticed, affecting both Penaeus vannamei and P. monodon.
