IDRC and NACA convened a workshop to identify the main research issues and needs to sustain Asian aquaculture into the first quarter of the 21st century, and also to bring them to the notice of relevant planners, managers and policy makers, and potential donors. The workshop was held in Rayong, Thailand from 4-7 June 2007. This report contains the issues papers drafted in preparation for the meeting and a summary of the discussions.

In this issue:

Developing guidelines for sustainable freshwater aquaculture planning in Vietnam. Aquaculture production, certification and trade for small-scale farmers. Backyard hatcheries for crustaceans in Thailand. Alternative carp species for diversification in India. Genetic and reproduction technologies for aquaculture and fisheries management of Murray cod. Status of sahar domestication in Nepal. Comparative advantage analysis of shrimp production in Asia. Strategies to improve the livelihoods of the rural poor, Vietnam, and more.

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.

L'élevage de la crevette est l’un des secteurs d'aquaculture le plus en essor dans beaucoup de régions du monde, il est également l’un des plus controversés. L'expansion rapide de ce secteur a généré, certes, des sources de revenus pour plusieurs pays, mais elle a été accompagnée par une préoccupation croissante sur les impacts environnemental et social. Les Principes Internationaux pour l'Elevage Responsable de la Crevette fournissent la base sur laquelle les parties prenantes peuvent collaborer pour un développement plus durable de l'élevage de crevette.

在世界许多地方，虾类养殖是水产养殖业增长最快，而且也是最具争 议的部门之一。这一部门的快速发展为许多国家创造了收入，但也伴随着 对环境和社会影响的忧虑。《负责任虾类养殖国际准则》在以更可持续的 方式发展虾类养殖方面为利益相关者之间开展合作提供了基础。《国际准 则》由虾类养殖与环境协作计划制定。该协作包括联合国粮食及农业组织 （粮农组织）、亚太水产养殖中心网、联合国环境规划署保护海洋环境免 受陆上活动污染全球行动纲领协调办公室、世界银行和世界自然基金会。

O Cultivo de Camarão é um dos setores de mais rápido crescimento na aqüicultura em várias partes do mundo e também o mais controverso. A rápida expansão deste setor possibilitou a geração de renda para muitos países, entretanto, ela tem sido acompanhada por crescentes preocupações sobre seus impactos ambientais e sociais. Os Princípios Internacionais para a Carcinicultura Responsável provêm a base sobre a qual todas as partes interessadas poderão colaborar para um desenvolvimento mais sustentável do cultivo de camarão.
