Under the FAO technical cooperation project (TCP/VIE/3304 (E)) Emergency assistance to control the spread of an unknown disease affecting shrimp, this final technical consultation on “Early Mortality Syndrome (EMS) or Acute Hepatopancreatic Necrosis Syndrome (APHNS) of Cultured Shrimp” was jointly organised by FAO and Vietnam’s Ministry of Agriculture and Rural Development from 25-27 June 2013, Prestige Hotel, Hanoi, Viet Nam.

Artisanal shrimp aquaculture is in a disease-induced crisis of lost production. The immediate cause is biological: rising levels of inbreeding and a strong, positive relationship between inbreeding and disease. The root cause is social: a nexus of human behavior in which breeders protect their intellectual property by generating inbreeding, local hatcheries sell copied, inbred shrimp, and farmers suffer the consequences.

In a major breakthrough, researchers at the University of Arizona have identified the causative agent behind "shrimp early mortality syndrome" or EMS, more accurately known as acute hepatopancreatic necrosis syndrome. The causative agent is a strain of a bacteria commonly found in brackish water, Vibrio parahemolyticus, with possible involvement of a phage. Very encouraging news. Congratulations to Dr Lightner's team and all that have assisted with the search for the culprit - Ed.
