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.

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.

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.

This case study provides (1) a description of the farming systems and management practices for mixed shrimp aquaculture-mangrove farming systems in the Mekong delta of Vietnam and (2) the findings from a detailed socio-economic study of these systems. The findings provide insight into the social and economic status of farmers involved in mixed aquaculture-mangrove farming, and the constraints associated with the adoption of management recommendations, with special consideration of the problems faced by poor farmers.

The integration of dry season shrimp farming into rice fields has raised incomes over several consecutive seasons for many farmers in the region. However, our study has revealed some key constraints that need to be addressed in order improve environmental and economic sustainability. The results of our study show that the traditional practice of recruiting native shrimp species through water exchange is not sustainable because of the attendant build-up of sedimentation on the farm.

This case study is based on a farm survey of 41 farms out of the total 340 farms in the Rushan County. The results presented in this paper highlight two main problems. The first issue revolves around labor cost statistics. The value of labor cost during the culture period forms a larger than proportionate ratio of total variable cost. The second problem lies in the high fixed cost incurred by rehabilitated farms.

This case study is based on review of existing publications/reports and stakeholder consultations. It is divided into three main sections, namely: 1) Background review on shrimp aquaculture in Bangladesh. 2) Results from a case study of farm management practices, hatcheries and wild shrimp fry collection and 3) Results from a case study on the social aspects of shrimp aquaculture, based on detailed local level studies in the Khulna region.

In Australia, strict Commonwealth and state environmental regulations have constrained development of shrimp farming. A high level of resources, relative to the size and value of the industry, has been devoted to collaborative research on the environmental management of shrimp farming in Australia. The research findings are being used to provide a scientific basis for discharge license requirements and are incorporated into an advanced geographic information and decision support system in order to improve site selection and aquaculture planning.

This document presents the report of the Expert Workshop on Management Strategies for Major Diseases in Shrimp Aquaculture. The report includes summaries of fifteen national review papers on the history and current national status of major shrimp diseases, including their socioeconomic impacts and an evaluation of the successes and failures of state and private sector interventions to solve major disease problems and to develop more sustainable shrimp culture industries, and four thematic reviews.
