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.

Since the Asia Pacific Emergency Regional Consultation on EMS/AHPNS held in August 2012 in Bangkok, Thailand, many news reports have been widely circulated that have led to various baseless speculations and conclusions on the true nature of AHPNS. This disease update/advisory has been issued to address the many circulating false and baseless speculations on the effects and spread of AHPNS in the region.
