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. 

This report reviews the state of shrimp aquaculture developent in Mexico, including its impact on employment, complexities surrounding coastal property rights, investment and health issues. Regulation and monitoring of the industry are still in their infancy, but SEMARNAP is putting in place a system that may be able to ensure that aquaculture will be sustainable. More effective involvement of the NGO community in the aquaculture sector may also help to monitor and ensure compliance with environmental regulations.

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.

Mahajal – The Big Fishing Net was written by Mr Rakesh Raman, a playwright from Ranchi, Jharkhand, and performed by his theatre troupe. The play was written as an interpretation of the outcomes of the project case studies carried out in Jharkhand, Orissa and West Bengal. Act One sets the scene of fisherfolk’s livelihoods and the difficulties they face in a tribal village. Act Two places the project’s policy change recommendations within the context of their lives and aspirations.

People who manage fisheries in the lower Mekong are beginning to think of themselves as a community within a common river basin. This is a different way of thinking; managing fisheries is no longer seen as an isolated activity but as a part of the life of people who live along the river. Previously, fisheries managers might have thought of their job as safeguarding or increasing fish production, but now they must share in the effort to alleviate poverty.

This review documents the status of shrimp aquaculture in relation to mangrove forest ecosystems. The environmental, social and economic impacts of shrimp farming are discussed, with examples covering both the negative and positive aspects of the sector. The review considers interventions and other activities to improve the sustainability of shrimp farming in the context of coastal zone management and the protection of mangrove ecosystems. The effectiveness of these interventions is considered in the light of experience based on case studies.

Shrimp aquaculture has been accused of threatening mangrove forests worldwide. Mangrove and shrimp ponds are known to have mutually supportive functions. Mangrove wetlands can treat effluents from shrimp ponds effectively by removing suspended solids and nutrients. This activity can be expected, in turn, to enhance mangrove productivity. This report describes an integrated mangrove wetland–shrimp farm operating in Colombia since 1996. At this site, shrimp farm effluent is recirculated through an 120 ha mangrove area.

This report discusses the recent history of shrimp aquaculture along the Caribbean coast of Colombia, with a focus on effective management practices that have been implemented since the mid-1990s. While the primary reason for using different practices has been preventing outbreaks of shrimp diseases, many such practices provide environmental benefits as well. Examples include reducing the use of water and ensuring that effluent entering natural water bodies is at least as clean as the intake water.
