Chúng tôi xin trân trọng được giới thiệu với bạn đọc cuốn sách Biện pháp phát triển nghề nuôi cá hồ chứa nhỏ ở châu Á. Mục tiêu của cuốn sách không nhằm hướng dẫn thực hành như tài liệu khuyến ngư, mà thực sự là công trình tổng kết kinh nghiệm từ kết quả thực tế của nhiều địa phương, kết quả nghiên cứu khoa học, và những cơ sở lý thuyết liên quan đến lĩnh vực này.

This technical paper provides an analysis of the economic implications of, and the reasons for, adopting various feeding practices for different fish species and aquaculture systems in Asia. The systems studied include extensive/traditional, semi-intensive and intensive farms for a number of different species including sutchi and pangasiid catfishes (Bangladesh and Viet Nam), hybrid catfish (Thailand), carp polyculture (India and China), prawn and milkfish polyculture (the Philippines).

This is a draft conservation strategy for the Mekong giant catfish prepared under the project Development of a conservation strategy for the critically endangered Mekong giant catfish, released for public consultation. The strategy considers the population and legal status, conservation vision and goals, factors affecting the wild population and outlines a conservation strategy. The document also considers monitoring, research and adaptive management and implementation issues given the transboundary and multi-institutional nature requirements for effective implementation.

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.

The primary objective of this manual is to provide guidelines for attaining better practices in culture-based fisheries, an emerging practice in rural areas in the Asian region. It deals will the principles of culture-based fishery practices, primarily based on relatively long-term experiences in Sri Lanka and Vietnam. It is not only targeted at researchers per se, but also at stakeholders at the grass root levels, as well as planners and policy developers.

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 2007, 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.

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 final report of the project “Strengthening Aquatic Animal Health Capacity and Biosecurity in ASEAN” contains two parts: A. Recommended Minimum Operational Requirements for Implementing National Aquatic Animal Health Strategies within ASEAN and B. ASEAN progress in the implementation of National Aquatic Animal Health Strategies. The report provides guidance for countries in ASEAN to implement key elements of national aquatic animal health strategies, and for monitoring progress of national strategy implementation in ASEAN member countries.
