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.

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.

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.

Culture-based fisheries in village reservoirs of Sri Lanka is a communal activity involving agricultural farmers without prior experience in fisheries. Awareness programs have facilitated establishment of CBF in small village reservoirs. Dissemination of research findings through means such as production of a documentary film, publication of a monograph which was translated to several regional languages, and holding a series of regional workshops were instrumental for CBF development at the regional level.

Releasing of giant freshwater prawn (Macrobrachium rosenbergii) for the purposes of stock enhancement and to create a fishery has been conducted in Thailand since the 1980s. Average age at harvest is around 6 to 8 months, with an average total length of 20 cm. Overall, the success of stocking M. rosenbergii is poor since the recapture rate is generally less than 5 %. However, the economic return is high.
