The 73rd edition of the Quarterly Aquatic Animal Disease Report contains information from 14 governments. The foreword provides information about the implementation of a National Surveillance Programme for Aquatic Animal Diseases (NSPAAD) in India.

Tilapia lake virus (TiLV) is an emerging disease of cultured tilapia in the Asia-Pacific region. Originally observed and reported in Israel, Ecuador, Colombia and Egypt, TiLV is now confirmed in cultured tilapia in Thailand causing mass mortalities. At risk is here is the US$7.5 billion global industry per annum, especially among the top tilapia-producing countries in the region including China, the Philippines, Thailand, Indonesia, Lao PDR and Bangladesh. This advisory describes signs of the disease and PCR detection methods.

In this issue:

The 15th meeting of the Asia Regional Advisory Group on Aquatic Animal Health; a regional consultation on responsible production and use of feed in aquaculture; a report on the Giant Prawn 2017 conference; a preview of the new NACA website; and new initiatives on a very serious emerging issue - reducing the human and animal health risks from development of anti-microbial resistance in the aquaculture industry.

Tilapia lake virus (TiLV) is an emerging virus that causes syncytial hepatitis of tilapia with mortalities of up to 90%. Recent disease outbreaks in Thai tilapia farms have been associated with high cumulative mortalities and histopathological features typical of SHT. Infection has now been confirmed. The semi-nested RT-PCR protocol described here may be used freely for non-commercial applications to detect TiLV. The authors urge laboratories in Asia to test for TiLV when abnormal tilapia mortality occurs.

The development of resistant strains of disease-causing microorganisms is an important health issue of global concern. When microbes such as bacteria, fungi, parasites, and viruses become resistant to antimicrobial substances, the diseases they may cause become more difficult or impossible to treat. Resistance is developed by the indiscriminate use of antimicrobials and places human health at risk. The discovery of antibiotics revolutionised medicine, creating a belief that a 'magic bullet' had finally been found to control bacterial diseases. Antibiotics, a class of antimicrobial agents, kill or inhibit the growth of bacteria, but they have no significant effect on other types of microorganisms such as viruses.

The fourth major international event on giant freshwater prawns was organised by the Asian Institute of Technology from 20-24 March 2007. The conference, organised by Salin Krishna and Michael New, built on a series of highly successful events that trace back to the very beginnings of the industry. The first conference, Giant Prawn 1980 brought together all those involved in freshwater prawn research and farming for the first time and set many priorities for future research and development.

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.

We invite you to join us for the 10th Symposium on Diseases in Asian Aquaculture (DAA10), the popular triennial event of the Fish Health Section of the Asian Fisheries Society (FHS-AFS), to be held from 28 August to 1 September 2017 at the Anvaya Beach Resort, Kuta, Bali, Indonesia.

With the chosen theme of “Enhancing Aquatic Animal Health Research and Services through Public-Private Sector Partnerships” we anticipate to cover topics from classic parasitic, bacterial and viral diseases to emerging trends and cutting-edge research in aquatic animal health.

Three satellite workshops: FAO’s Inter-regional Workshop, NACA’s Meeting of the Asia Regional Advisory Group on Aquatic Animal Health, and a Bioinformatics Workshop are being organised back-to-back with DAA10.

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.
