This book is the proceedings of the “Regional Consultation on Culture-Based Fisheries Development in Asia”, held in Siem Reap, Cambodia, 21-23rd of October 2014, under the auspices of the Australian Centre for International Agricultural Research (ACIAR), the Mekong River Commission (MRC) and the Network of Aquaculture Centres in Asia-Pacific (NACA). The consultation was jointly organised by NACA and the Fisheries Administration of the Royal Government of Cambodia.

The workshop, organised by FAO and NACA, was intended to enhance the capacity of national focal Points on Aquatic Genetic Resources within Asia-Pacific Region regarding the preparation of national reports on the current status of aquatic genetic resources for food and agriculture. These will be used as the major source of information for the first State of the World’s Aquatic Genetic Resources for Food and Agriculture report.

FAO and NACA convened a stakeholder consultation in Bangkok 25-27 March 2015 to discuss development of an environmental monitoring system for the lower Mekong Basin. The objective of the system is to strengthen the resilience of fisheries and aquaculture and to improve early warning for fishers and farmers. The workshop was preceded by baseline assessments of existing environmental monitoring and early warning systems relevant to fisheries and aquaculture in the target area.

This report, the 68th in the series, contains information about the aquatic animal health status of thirteen states in the Asia-Pacific region. The foreword discusses harmonisation in ASEAN aquaculture certification.

Transboundary aquatic animal diseases are one of the major concerns for strengthening of aquatic animal health management capacity in the region. The spread of these diseases demonstrates the vulnerability of the aquaculture industry, as well as the wild fish populations, to disease emergence where impacts have been exacerbated by the lack of preparedness. NACA's Aquatic Animal Health Programme, established in 1998, provides a mechanism for regional governments to coordinate disease preparedness, surveillance and response.

Domestication in livestock industries is the process in which animal populations change in response to the artificial environments of farming production systems. Significant and widespread economic gains have been achieved through genetic improvements made through domestication and selective breeding of commercially farmed shrimp species, particularly Litopenaeus vannamei. Different policies on the translocation of shrimp genetic resources have influenced the approaches to shrimp domestication in different countries. The present paper examines the different approaches.

In early 2013, Vibrio parahaemolyticus was discovered as the causative agent of acute hepatopancreatic necrosis disease (AHPND). Subjecting 4 arbitrarily selected V. parahaemolyticus isolates obtained from a single farm in November 2012 to the previously reported immersion challenge protocol, we confirmed that 3 caused high mortality at different rates accompanied by characteristic lesions of AHPND while 1 caused high mortality without such lesions. Virulence may be determined by mobile genetic elements such as plasmids or bacteriophages.
