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.

El cultivo de camarón es uno de los sectores de la acuicultura de más rápido crecimiento y también uno de los más polémicos en muchas partes del mundo. La rápida expansión de este sector generó ingresos para muchos países, pero ha estado acompañada por preocupaciones crecientes relacionadas con sus impactos ambientales y sociales. Los Principios Internacionales para el Cultivo Responsable de Camarón proporcionan las bases sobre las cuales los diversos participantes pueden colaborar en pro de un desarrollo más sostenible de la camaronicultura.

Shrimp Health Management brochures provide better management practices in a reader friendly format. These brochures were prepared as extension materials through the village based demonstration programme by the Marine Products Export Development Authority of India and NACA. The programme continues building success and involved a total of 29 villages and 29 Aquaclubs in five Indian states (Andhra Pradesh, Tamilnadu, Orissa, Gujarat, and Karnataka) in 2006.

Shrimp farming is one of the fastest growing aquaculture sectors in many parts of the world and also one of the most controversial. Rapid expansion of this sector generated income fo many countries, but has been accompanied by rising concerns over environmental and social impacts. The International Principles for Responsible Shrimp Farming provide the basis upon which stakeholders can collaborate for a more sustainable development of shrimp farming.

In order to provide practical and effective technical guidance for shrimp hatchery management, it is necessary to establish a set of better management practices (BMPs) which underpin an effective hatchery production system. This document is not a complete manual on the management of P. monodon hatcheries but concentrates on the implementation of BMPs for the hatchery covering all of the critical stages and processes in the production cycle, which are currently believed to be causing problems in Vietnamese hatcheries. 

This report describes the experiences and lessons learnt from activities conducted by NACA in Viet Nam to support the sustainable development of the aquaculture sector using better management practices and harmonised strategies for the management of aquatic animal health and environmental problems. Achievements included reducing the risk of diseases from seed and on farms, developing capacity at the provincial and national levels, developing an effective surveillance system and wide dissemination of experiences.

This case study reviews shrimp aquaculture development in East Africa and the Middle East, as well as the problems and prospects for future development. Given that shrimp aquaculture development has not yet occurred on any significant scale, although increasing, it should be possible to learn the lessons from other parts of the world and apply them in these contexts. The countries in this report are: Egypt, Iran, Mozambique, Madagascar with some information on other countries in both regions.

This report provides details of the activities and outcomes of work conducted under the World Bank, NACA, WWF and FAO consortium program on Shrimp Farming and the Environment. The report synthesises the major findings of the consortium program from 1999-2002. It includes the outcome from a stakeholder workshop that discussed the program findings, hosted by the World Bank in Washington DC, in March 2002.

Este reporte da detalles de las actividades y resultados del trabajo conducido bajo el Programa en Consorcio del Banco Mundial, NACA, WWF y FAO sobre “Cultivo de Camarón y el Medio Ambiente”. Este reporte sintetiza los resultados más importantes del programa del consorcio desde 1999 hasta marzo de 2002. Incluye los resultados de los talleres de usuarios que discutieron los resultados del programa, auspiciados por el Banco Mundial en Washington, DC, en marzo de 2002. 

Belize Aquaculture, Ltd., has developed a superintensive shrimp aquaculture system operating in lined ponds with heavy mechanical aeration and water recirculation. The pilot study has been in progress for two years. Shrimp production has ranged from less than 8,000 kg/ha to more than 20,000 kg/ha per crop. Because the Belize Aquaculture, Ltd., production system appears to address a number of the environmental impacts of traditional shrimp aquaculture systems, a case study of this unique system was conducted.

Several stakeholder groups have formulated and recommended the implementation of better management practices (BMPs)aimed at improving production efficiency and/or ameliorating impacts of shrimp farming on the environment. In this study, an economic optimisation model with an environmental component was used to evaluate the effects of five specific BMPs on the profitability, optimal selection of management strategies, and net quantities of nutrients discharged by semi-intensive shrimp farms in Honduras and small-scale operations in Honduras and Nicaragua.

Most marine fish farms in Asia still rely on what is commonly termed "trash fish". Despite it's apparent abundance and availability, there are some issues and problems related to its use in fish farming. This guide explores new and better farming practices making use of formulated feeds, as well as technical aspects of feed storage and quality control, management of feeding including weaning of groupers onto formulated feeds and economic considerations.
