Tropical shrimp aquaculture is facing a disease crisis that may be propelled by an interaction between management practices that cause inbreeding, and the amplification by inbreeding of susceptibility to disease and other stresses. Broodstock accumulate inbreeding and lose genetic diversity when they experience bottlenecks or are chronically too small. The genetic lock is a practice that leads to inbreeding at farm level. Inbreeding may be amplifying the severity of diseases, including the major current threats.

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.

The twelfth meeting of NACA’s Technical Advisory Committee (TAC) was held in the coastal town of Cha-am, Thailand from 9-12 March. The TAC meets every two years to review NACA’s rolling work programme and propose amendments to realign it with the current needs of member governments and to account for new and emerging issues. In proposing changes, the TAC prioritises issues of common concern to member governments where there are prospects for regional collaboration.

The objectives of the Aquaculture for Food Security, Poverty Alleviation and Nutrition (AFSPAN) project were to strengthen the knowledge base and develop new and more rigorous methodologies of quantifying the contribution of aquaculture to combat hunger and poverty, thus providing the evidence upon which sound strategies, policies and research programs can be developed to support the sustainable expansion of aquaculture to maximise its impact on food and nutrition security and poverty alleviation.

The Gender and Aquaculture Seminar: Equity and Regional Empowerment in the Aquaculture Value Chain, a culminating activity for the NACA/USAID/MARKET Project’s Thematic Studies of Gender in Aquaculture, was held from 24 to 25 February 2015 in Bangkok. The project conducted research on womens’ roles and influence on selected aquaculture value chains in Cambodia, Lao PDR, Thailand and Vietnam. The goal of the research was to raise awareness and increase recognition of gender roles.

The emergence and spread of new or previously unknown infectious diseases has had very significant impacts on public health, food security and international trade. Disease emergence is the consequence of environmental and/or sociological changes that disrupt the ecological relationship between pathogens and their natural hosts. Understanding the drivers of disease emergence will help us develop policies and practices that will reduce opportunities for disease emergence in aquaculture and improve prospects of containment.

A new method for the detection of AHPND-bacteria (AP4) has been published and is available for download. The advantage of the AP4 method over the previously published AP3 method is that it has 100 times higher sensitivity. Because of its higher sensitivity, the bacterial culture enrichment step needed when using the AP3 with low levels of AHPND bacteria may be omitted. However, the AP4 method should not be considered as a replacement for AP3.

The USAID Maximizing Agricultural Revenue through Knowledge, Enterprise Development, and Trade (MARKET) Project and NACA are hosting a Gender and Aquaculture Seminar: Equity and Regional Empowerment in the Aquaculture Value Chain on February 24-25 in Bangkok, Thailand. The USAID MARKET Project and NACA have undertaken a year-long research project on women’s roles and influence on selected aquaculture value chains in four countries in Southeast Asia.

This report, the 67th in the series, contains information about the aquatic animal health status of fourteen states in the Asia-Pacific region. The foreword discusses the OIE Regional Workshop on Safe International Trade in Aquatic Animals and Aquatic Animal Products.
