Genetics and Biodiversity

This manual provides a comprehensive practical tool for the generation and analysis of genetic data for subsequent application in aquatic resources management in relation to genetic stock identification in inland fisheries and aquaculture. The material only covers general background on genetics in relation to aquaculture and fisheries resource management, the techniques and relevant methods of data analysis that are commonly used to address questions relating to genetic resource characterisation and population genetic analyses.

This is the second part of the manual Application of molecular genetic techniques in aquaculture and inland fisheries management. It provides a step-by-step laboratory protocols and methodologies for data analysis and a guidelines to design a population genetic study. The scope covers most commonly used techniques for screening genetic variation, general background on the methodologies for estimation of important parameters in population genetic studies for different forms of molecular genetic markers.

The aim of this manual is to provide a comprehensive practical tool for the generation and analysis of genetic data for subsequent application in aquatic resources management in relation to genetic stock identification in inland fisheries and aquaculture. Part 1: Conceptual basis of population genetic approaches provides a basic foundation on genetics in general, and concepts of population genetics. Issues on the choices of molecular markers and project design are also discussed.

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.

Viet Nam's mangrove forests have been severely impacted by human interventions, with a reduction in forestation from 408,000 ha in 1943 to a low of 150,000 ha in 2000. This study provides an overview of the information needs and communication issues surrounding people living in mangrove regions of Viet Nam. It is hoped that this study will help to raise the awareness of issues surrounding mangrove environments and improve the accessibility to information, for all stakeholders.

This reports describes the status of mangrove ecosystems and associated communities in the Mahakam Delta, Indonesia. It describes historical degradation of the mangrove ecosystems for shrimp farming and land speculation. The report describes the livelihoods of the local communities, their usage and connections with the mangrove forests and farming activities, and socio-economic factors impeding the restoration of mangrove habitats, which are in large part related to poverty. Attempts to replant areas are described.

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.

These are the proceedings of two Workshops on Capacity Building for Situation Analysis of Mangroves Ecosystem and Communities, held in Hanoi and Nam Dinh, 4-8 December 2006. The workshop focused on developing the knowledge and skills of the VNU team in Sustainable Livelihoods Analysis through the application of Participatory Rural Appraisal (PRA) techniques. The workshops were funded under the European Union Mangrove Project (2005-2008) in preparation for commencement of field-based activities and situation analysis.

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.
