The Asia Regional Advisory Group on Aquatic Animal Health meets annually to discuss regional health issues including emerging disease threats. This report includes a review of regional disease status circa 2016, global and regional disease reporting arrangements, global issues and standards, progress in implementation of the the Regional Technical Guidelines on Health management for the Responsible Movement of Live Aquatic Animals, identification and designation of regional aquatic animal health resources and regional and international cooperation.

The 15th meeting was held from 21-23 November 2016, in Bangkok, Thailand. A special session was held on addressing the use of anti-microbial substances in aquaculture and the development of anti-microbial resistance. This is an issue of global concern for both human and animal health, and it had been addressed by a resolution at FAO’s Thirty-ninth Conference in June 2015. The meeting reviewed in detail the status of aquatic animal disease in the region.

Culture-based fisheries (CBF) are a useful development strategy for improving the income and food security of rural communities. CBF requires minimal capital outlay, mobilising farming communities to make use of existing small dams and reservoirs for the secondary purpose of foodfish production. The objective of this project is to introduce community-based CBF to Cambodia, and to consolidate the gains of communities that have adopted CBF in Lao PDR.

The objective of this project was to develop an agreed code of practice for the transboundary movement of aquatic organisms that feeds into the fisheries management strategy for the lower Mekong basin. The code of practice provides guidance on risk management and mitigation measures be taken into account for live aquatic animal imports or other transfers that are part of the established commercial practice, or those related to scientific study at research facilities.

Hepatopancreatic microsporidiosis (HPM) caused by Enterocytozoon hepatopenaei (EHP) is a newly emerging disease of cultivated shrimp in Asia. Current evidence indicates that it can be associated with severe growth retardation that may not be clearly evident until the second month of culture and may cause low continuous mortality in the case of very severe infections. We present a new method for detecting EHP that has superior specificity to the first generation SSU-PCR developed in 2009.

The Second International Technical Seminar/Workshop on AHPND: There is a way Forward! will be held from 23-25 June 2016 in Thailand. The purpose of the meeting is to update knowledge and exchange experiences in dealing with AHPND, to validate current concepts and models under different systems and environmental conditions and to put into action the responsibilities of the different sectors (i.e. government, producer and academe) as a way forward to deal with AHPND.

This publication is the major output of a regional programme jointly implemented by FAO and NACA in 2015 to document and disseminate successful practices that contribute to the sustainable intensification of aquaculture in the Asia-Pacific region. Twelve practices are described that contribute to at least one of the following: Improved production and resource use efficiency (land, water, feed, energy); improved environmental benefits; strengthened economic viability and farmers' resilience; and improved social acceptance and equity.

This disease card describes the diagnosis and range of a microsporidian shrimp pathogen, Enterocytozoon hepatopenaei (EHP), first discovered in Penaeus monodon in Thailand in 2004. It infects only the tubule epithelial cells of the hepatopancreatic tissue of shrimp. EHP was later found to also infect P. vannamei cultivated in Thailand and is suspected to have been reported from P. japonicus in Australia in 2001. EHP has been reported from Vietnam and is associated with white faeces syndrome.

A Regional Proficiency Testing Program for Aquatic Animal Disease Diagnostic Laboratories in Asia-Pacific was developed to strengthen diagnostic capability across Asia. This capability was identified as a requirement to facilitate the sanitary safety of trade in aquatic animal products. The program provided 41 laboratories across the Asia-Pacific with the opportunity to assess their diagnostic performance for 10 regionally significant aquatic animal pathogens, and to adapt or modify practices where necessary to improve.

In early 2013, Vibrio parahaemolyticus was discovered as the causative agent of acute hepatopancreatic necrosis disease (AHPND). Subjecting 4 arbitrarily selected V. parahaemolyticus isolates obtained from a single farm in November 2012 to the previously reported immersion challenge protocol, we confirmed that 3 caused high mortality at different rates accompanied by characteristic lesions of AHPND while 1 caused high mortality without such lesions. Virulence may be determined by mobile genetic elements such as plasmids or bacteriophages.

A special session on Regional Cooperation for Improved Biosecurity was held at the World Aquaculture Adelaide 2014 conference, from 7-11 June. The session discussed i) regional cooperation in biosecurity, ii) dealing with emerging diseases, focussing on acute hepatopancreatic necrosis disease, and iii) domestication programmes and their implications for genetic diversity, disease susceptibility and resistance.
