This report is the proceedings of a workshop held under the FAO technical cooperation project Emergency assistance to control the spread of an unknown disease affecting shrimps held in Hanoi, Viet Nam from 25 to 27 June 2013. The workshop reviewed recent investigations into the cause of acute hepatopancreatic necrosis syndrome, believed to related to a strain of Vibrio parahaemolyticus and drew a number of recommendations on specific and generic actions and measures for reducing the risk of AHPND.

A new FAO Fisheries and Aquaculture Report, Early Mortality Syndrome (EMS) or Acute Hepatopancreatic Necrosis Syndrome (AHPNS) of Cultured Shrimp, focuses on this emerging disease that has devastated the shrimp industry of China, Malaysia, Thailand and Viet Nam over the last three years.

The Department of Animal Husbandry Dairying and Fisheries, Ministry of Agriculture, Government of India has approved a national project on aquatic animal disease surveillance for five years and funding of INR 320 million (about US$ 6 million) has been allocated through the National Fisheries Development Board (NFDB). A national consultation on aquatic animal disease surveillance held last April 2012, attended by NACA, made a strong recommendation for the need for a national program on surveillance.

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.

These are the proceedings of the FAO/AAHRI Expert Workshop on Improving Biosecurity through Prudent and Responsible Use of Veterinary Medicines in Aquatic Food Production, held in Bangkok, Thailand, from 15 to 18 December 2009. The workshop discussed the current status of antimicrobial usage in aquaculture and the impacts of their irresponsible use on human health, the aquatic environment and trade. The outcomes are relevant to the development of guiding principles on the responsible use of antimicrobials in aquaculture.

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.

This report, the 60th in the series, contains information about the aquatic animal health status of fifteen states in the Asia-Pacific region. The foreword discusses response to aquatic animal disease emergencies.
