Everything You Wanted to Know about EMS/AHPNS*

(*Except What Causes it)

 

 

On August 9-10, 2012, in Bangkok, Thailand, the Network of Aquaculture Centers in Asia (NACA) and the Australian Department of Agriculture, Fisheries and Forestry convened an emergency consultation on an emerging shrimp disease called acute hepatopancreatic necrosis syndrome, (AHPNS), formerly referred to as early mortality syndrome (EMS).  At the consultation, 19 shrimp disease experts from around the world gave presentations on the occurrence, pathology and diagnosis of AHPNS, which has caused significant losses on shrimp farms in China and Vietnam (2010), Malaysia (2011) and Thailand (2012).  It affects Penaeus monodon and P. vannamei and is characterized by an abnormal hepatopancreas, corkscrew swimming, loose shells, pale coloration, slow growth and mass mortalities during the first 20-30 days of culture.  The cause is unknown.

 

You can listen to the 19 presentations from the consultation on the Internet.  When you click on one of the listings below, a page will open with the name of the presentation, but you must click on the green arrow () after the presentation’s title to start the audio.  If you want to download the audio presentation to your desktop, click on the music symbol (♫) after the presentation’s title.  In English and ranging in length from about ten minutes to a half hour, they are all good and informative.  I particularly enjoyed Dr. Matt Briggs presentation, “Is EMS a Management Problem”, because of his discussion on the differences between EMS and AHPNS.
