Infectious myonecrosis is a viral disease caused by infectious myonecrosis virus. It affects Pacific white shrimp Penaeus vannamei, tiger shrimp P. monodon and blue shrimp P. stylirostris. IMN is associated with heavy losses in farmed shrimp of 40-70%. Originally reported from Brazil, outbreaks were first reported in Indonesia in May 2006. With the current spread of the disease there is a high threat of the disease spreading to neighbouring P. vannamei-producing countries.

This report, the 50th in the series, contains information about the aquatic animal health status of thirteen states in the Asia-Pacific region. The foreword discusses food safety and biosecurity.

Species movement for farming can be one of the many sources of biological threats to the well-being of farmed aquatic animals, humans and ecosystems. Transboundary aquatic animal diseases may occur due to illegal introductions and transfers of live animals. This session will discuss aspects of biosecurity as possible and will identify successes and failures, issues of importance and the role of biosecurity in the sustainable increase in aquaculture production. 

The Phuket Consensus is a declaration on aquaculture development endorsed by participants of the Global Conference on Aquaculture 2010, held in Phuket, Thailand, 22-25 September. The consensus builds on the Bangkok Declaration, which was formulated at the International Conference on Aquaculture in the Third Millennium, held in Bangkok, 20-25 February 2000. The consensus and declaration provide strategic guidance on sustainable development of aquaculture considering social, environmental, technical and economic issues.

On 9-10 August 2012, an emergency regional consultation on Early Mortality Syndrome of shrimp and associated pathology described as acute hepatopancreatic necrosis syndrome  was held in Bangkok, Thailand. The consultation shared information on this emerging disease, its occurrence, pathology and diagnosis, and to develop a coordinated regional response to the issue. Audio recordings of 19 technical presentations made at the regional Consultation meeting are available on NACA website, and the presentation slides are also available.

This report, the 49th in the series, contains information about the aquatic animal health status of fifteen states in the Asia-Pacific region. The foreword discusses the outcomes of the ninth meeting of the Asia Regional Advisory Group on Aquatic Animal Health.

This report, the 48th in the series, contains information about the aquatic animal health status of fifteen states in the Asia-Pacific region. The foreword discusses current fish health concerns.

In this issue:

The Dedanaw Project, Myanmar. The changing face of women for small-scale aquaculture in Bangladesh. Strengthening capacity of small holders in ASEAN. Carp seed production in Orissa, India. Sustainable mountain paddy-fish farming of the Apatani tribes. The economic impacts of whitespot virus on shrimp production in Iran. Current practices of marine finfish cage culture in China, Indonesia, Thailand and Vietnam. Effects of trash fish on growth and body composition of cobia.

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 2009, 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.

Inland fisheries resource enhancement has been considered a major component of reservoir fisheries management since 1962. Multipurpose reservoir construction commenced about the 1960s for irrigation, hydropower generation and flood control. Reservoir fisheries are always a secondary or tertiary activity and are given low priority; however stocking has been considered a major component of reservoir fisheries management. This presentation reviews the history of and changes to stock enhancement practices in Vietnamese reservoirs since the 1960s.
