This report provides a quantitative assessment of the conservation of the Mekong giant catfish, Pangasianodon gigas, and an evaluation of the likely effectiveness of different conservation options. The report conisders the history of fisheries exploitation and environmental change, the estimated wild population size of P. gigas, the role of captive populations held by the Thailand Department of Fisheries and interactions with cultured fish. It makes a series of recommendations for conservation of this species.

This is a brief of a project to develop an overarching conservation strategy for the Mekong giant catfish integrating supportive breeding with harvest and habitat management. This will involve (1) quantitative assessment of population status based on existing information, (2) quantitative assessment of the likely effectiveness of different conservation measures (3) review and improvement of captive breeding procedures; (4) promotion of appropriate adaptive policies for the further development of the strategy; and (5) definition of an overall conservation strategy.

This is the report of the Second Mekong Giant Catfish Working Group Meeting, held in Phnom Penh 12-13 November 2005, under the project Development of a conservation strategy for the critically endangered Mekong giant catfish. The purpose of the workshop was to review existing knowledge on Mekong giant catfish, identify future conservation and research priority activities, and to continue the joint planning process aimed at developing an overarching conservation strategy.

This report describes a training course on marine finfish hatchery protocols, which was convened at the Karabi Coastal Fisheries Research and Development Center, Thailand at the request of the Secretariat of the Pacific Community. The main goal of the training was to carry out hands-on practical work in finfish hatchery techniques, with an emphasis on grouper. This work involved spawning induction, incubation and larval rearing until day 12.

This report, the 38th in the series, contains information about the aquatic animal health status of seventeen states in the Asia-Pacific region. The foreword discusses the OIE/NACA Regional Workshop on Aquatic Animal Health.

The 5th Regional Grouper Hatchery Training Course was another success with all participants is pleased with the overall training activities and field trips. A total of 17 participants from eight countries attended the training course which was hosted by the Brackishwater Aquaculture Development Centre, Situbondo, Indonesia. Participants were able to involve in the broodstock activities for giant grouper, in additional to the tiger and humpback groupers, and attended field trips to backyard hatcheries and export facilities.

This is the report of the project Application of PCR for improved shrimp health management in the Asian region. The training programme included two training workshops that were designed to provide a good understanding of PCR methodology, laboratory practices and trouble shooting in detection of both DNA and RNA viruses. The workshops were followed by by two rounds of an anonymous PCR inter-calibration or ring testing exercise to allow laboratories to gauge their own performance.

This training manual (in Thai language) provides guidance in marine finfish cage aquacutlure techniques. It is geared towards giving small-scale farmers a solid technical grounding that will enable them to improve their farm productivity and reduce losses through understanding of markets and economic factors, better farm siting. and improved feeding, handling and stock management practices. This knowledge will help the trainees and other fish farmers to improve their productivity and profitability while also reducing their risk profile.

This report, the 37th in the series, contains information about the aquatic animal health status of fourteen states in the Asia-Pacific region. The foreword discusses emerging diseases in the region.

In 2006 the COFI Sub-Committee on Aquaculture noted that many non-governmental certification schemes have resulted in higher costs for producers without delivering significant benefits to small-scale producers. An international round of consultations were commissioned to discuss the development of globally accepted certification guidelines for aquaculture production, which could provide more guidance and serve as a basis for harmonisation and mutual recognition. This is the report of the first consultation workshop, held in Bangkok, March 2007.

This report, the 36th in the series, contains information about the aquatic animal health status of fifteen states in the Asia-Pacific region. The foreword discusses recent activities in support of aquatic animal health in the region.
