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.

This paper reviews feeds and feed management practice in shrimp aquaculture and assesses the trends and environmental implications of feed use. Particular attention is given to the use of fish meal in shrimp diets and water pollution caused by feeds. The review identifies practices at farm, manufacturing and ecosystem levels that can reduce environmental impacts associated with the use of shrimp feeds. Trends in the use of alternative ingredients to replace fish meal are also considered.

The rapid expansion of marine shrimp aquaculture in many tropical developing countries has proceeded without effective environmental regulation. Most countries with shrimp farming do not have an established regulatory apparatus to monitor and enforce environmental and socioeconomic standards. Therefore, voluntary codes of conduct are a possibility for improving overall management and possibly profitability of the marine shrimp aquaculture industry until effective governmental regulation is implemented. This paper reviews the status of existing codes of conduct for shrimp farming.

Various substances in shrimp farm ponds can contaminate waters, including nutrients, metabolic wastes, veterinary chemicals, and suspended soil particles from erosion. This report discusses ways to monitor these aspects of water quality, which is important from two standpoints for shrimp farmers. Incoming water used top supply shrimp ponds must be healthful and free of toxins to protect the growing shrimp, and effluent must be clean enough to avoid harming aquatic ecosystems and water quality standards downstream.

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.

This case study discusses the main lessons for management practices learned at the shrimp farm Camanor, in Rio Grande do Norte, Brazil. Since it was founded in 1982, the farm has yielded data that allow the lessons and insights to be drawn. This case documents the most important lessons learned by Camanor during the past 18 years. The most important challenges before the shrimp aquaculture industry involve developing better practices and implementing industry wide standards that are more sustainable.

The purpose of this study is to assess the development of the shrimp farming industry in Brazil, identifying past obstacles and key incentives for its expansion. The shrimp industry has taken longer to develop in Brazil than in other countries. Despite favorable conditions, it is only recently that successful efforts are consolidating. This report analyzes the main factors that have inhibited the development of the industry and describes the sector's current characteristics.

The main output of the International Conference on Aquaculture in the Third Millennium. The Declaration summarises the key impediments and opportunities in aquaculture development that are likely to arise over the next 20 years and provides strategic policy guidance for sustainable aquaculture development. The Declaration was adopted by conference participants in a plenary session.

In February 2002 the shrimp fry collection ban was placed into abeyance pending further review of how biodiversity could be conserved at the same time as protecting the livelihoods of 400,000 fry collectors. A Shrimp Action Plan for the period April - September 2002 was drawn up to identify trends impacting on distribution and growth in the shrimp sector, and to explore alternative models for the management of fry resource and to assess their social, institutional and economic implications.
