A technical presentation on selection of appropriate species in culture-based fisheries.

A presentation on the current state of culture-based fisheries practices in China.

The first ever Regional Training Course on Culture-based Fisheries in Inland Waters was held at Nha Trang University from 30 October to 8 November. The objective of the course was to provide participants with the skills to assist local communities to plan and manage culture-based fisheries. These practices are an example of a relatively simple and low cost technology that can deliver nutritional and economic benefits to rural communities, which often have few livelihood options.

Since 2009, tilapia aquaculture has been threatened by mass die-offs in Israel and Ecuador, which have been caused by a novel Orthomyxo-like (RNA) virus named Tilapia lake virus. This has been reported as a newly emerging virus that causes syncytial hepatitis of tilapia. An emergency regional consultation was held in Guangzhou, China from 27-28 September 2017 to discuss and plan actions on the overall prevention and management of this disease.

A regional consultation on aquaculture feed production and use in Asia-Pacific was held from 7-9 March 2017. The consultation reviewed the current situation of aquaculture feed production and use, sourcing of ingredients, policy and research needs. This collection contains audio recordings of the technical presentations made by experts, international organisations, the private sector and governments in the region. The report of the consultation is in press and will be made available for download in due course.

The China Aquatic Products Processing and Marketing Alliance will convene Asia Pacific Aquaculture Expo (June 30-July 2, 2017) and Global Aquaculture Summit (June 29-July 1, 2017) in Fuzhou City, China. The Asia Pacific Aquaculture Expo is the only aquaculture themed exhibition in China, covering the whole industry chain from feed, seed, to machinery and products, while the Global Aquaculture Summit is China's top aquaculture conference and enjoys a high level of international participation.

Recently, we released a warning of TiLV in Thailand and an improved RT-PCR detection methodology. The Fish Health Platform in Centex, BIOTEC/Mahidol University has also obtained positive test results for TiLV in other Asian countries where it has not yet been reported. Many countries have been translocating tilapia fry/fingerlings prior to and even after the description of TiLV. We have prepared a map listing countries with confirmed reports of TiLV infections and 43 other countries that we believe have imported infected fish.

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.

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.

China is the world's largest producer of aquaculture feeds. With the development of aquaculture, the feed industry has inevitably faced some challenges in promoting update of commercial feeds, pollution, use of trash fish, fish meal and fish oil issues, provision of accurate nutrition and feeding, antibiotic residues, food safety, and so on. In order to balance economic and environmental issues the Chinese Government released its 13th Five-year Plan last year. Trends and policy changes relevant to aquaculture are discussed.
