A series of leaflets on better management practices for Penaeus monodon shrimp aquaculture in Vietnam. The leaflets are available in both Vietnamese and English and cover: Broodstock management for suppliers, postlarvae selection and transportation for seed traders, shrimp seed quality, pond preparation, good pond management, shrimp health management.

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.

In this issue:

Small-scale pond culture in Bangladesh. Issues and challenges in community-based aquaculture. Aquaculture as an action programme building confidence and self-worth. Transforming policy recommendations into pro-poor service provision. Grow out of spotted Babylon to marketable size in polyculture with seabass. Influence of economic conditions and global shocks on grouper markets. Status of cobia hatchery technology in Vietnam. Organic shrimp raceway system. Macrobrachium rosenbergii in Vembanad Lake. Management of monogenean parasites.

This presentation provides an overview of Vietnamese experience on the implementation of better management Practices (BMPs) and good aquaculture practices (GAP) in shrimp aquaculture. Practices were implemented collectively by encouraging small-scale farmers to form groups that collaborate on issues such as screening seed for disease and improving water quality management. Improvements to crop outcomes were observed. The results presented include the profitability of BMP adopted ponds.

Presentation on a MPEDIA/NACA intiative to implement better management practices for shrimp farming amongst small-scale farmers in India via formation of farmer groups. The practices are based on the International Principles for Responsible Shrimp Farming. Adoption of improved farming practices reduces the incidence of disease and improves crop outcomes for small-scale farmers. This presentation was made at the World Aquaculture Society Conference in Bali, Indonesia, 2005.

The case study for this report was conducted in the coastal village Pematang Pasir, Sumatra, Indonesia. Pematang Pasir hosts a pilot project promoting environmentally and responsible shrimp aquaculture implemented by the Indonesian Coastal Resources Management Project. This paper describes the lessons learned to date and offers strategies for community-based coastal resource management, which can be used in a broader perspective as more general guidelines for community-based and participatory development of shrimp aquaculture in marginalised coastal areas.

Shrimp farming in southern Honduras has generated considerable controversy around the issues of natural resource access and management. This case study reviews the reasons for and history of that controversy. The study relies on an extensive literature review and insights from the author’s previous research trips to southern Honduras between 1991 and 2000. In addition, representatives from several government offices, the shrimp industry, and the primary nongovernmental organisations were interviewed in May 2000.

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.

In this issue:

Asian Development Bank study on aquaculture and poverty. The consequences of converting to organic shrimp farming. Recycling water and making money with Artemia. Advances in the seed production of cobia Rachycentron canadum in Vietnam. Australian success with barramundi cod Cromileptes altivelis. Recent grouper breeding developments in Thailand. Application of probiotics in rotifer production systems. Contract hatchery systems. Rainbow trout culture in Iran. Spotted babylon Babylonia areolata growout in earthern ponds.

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.

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.

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.
