Possible improvements to carp culture in Andhra Pradesh. Aquaculture and environmental issues in the region of Nai Lagoon, Vietnam. Selection potential for feed efficiency in farmed salmonids. Freshwater prawn broodstock concern in Bangladhesh hatcheries. Production of Cirrhinus molitorella and Labeo chrysophekadion for culture-based fisheries in Lao PDR: Nursery and grow-out. Mussel farming: Alternate water monitoring practice. Use of poultry by-product meals in pelleted feed for humpback grouper Cromileptes altivelis.

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.

In this issue:

From integrated carp polyculture to intensive monoculture in the Pearl River Delta, China. Better management practices for Vietnamese catfish. Ipomoea aquatica - an aquaculture friendly macrophyte. Status of fisheries and aquaculture development in Pakistan. The changing face of post-grad education in aquaculture: Contributing to soaring production and sustainable practices. Hatchery management in Bangladesh. Production of Cirrhinus molitorella and Labeo chrysophekadion for culture-based fisheries in Lao PDR and much more.

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.

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.
