Book (series)The hatchery culture of bivalves: a practical manual 2004Bivalve mollusc culture is an important and rapidly expanding sector of world aquaculture production, representing approximately 20% of this output at 14 million tonnes in 2000. The majority of production is from natural populations although increasingly stocks are approaching or have exceeded maximum sustainable yields. Enhancement of stocks through the capture and relaying of natural seed in both extensive and intensive forms of culture is common practice worldwide but the reliability of natur al recruitment can never be guaranteed and conflicts over the use of the coastal zone are becoming ever more pressing. A solution to meeting the seed requirements of the bivalve industry, applicable to the production of high unit value species such as clams, oysters and scallops, is hatchery culture. The production of seed through hatchery propagation accounts at the present time for only a small percentage of the total seed requirement but it is likely to become increasingly important as work continues to produce genetically selected strains with desirable characteristics suited to particular conditions. The advent of bivalve hatcheries was in the 1960s in Europe and the U.S. Since those early pioneering days knowledge of the biological requirements of the various species that predominate in worldwide aquaculture production and the technology by which to produce them has and continues to improve. This manual brings together the current state of knowledge in describing the v arious aspects of hatchery culture and production from acquisition of broodstock to the stage at which the seed are of sufficient size to transfer to sea-based growout. Focus is on intensive methodology in purpose built hatchery facilities rather than on more extensive methods of seed production in land-based pond systems. This manual is not intended as a scientific treatise on the subject. Rather, it is practical in nature providing the reader with an insight into what is required in the w ay of resources and details of how to handle and manage the various life history stages of bivalves in the hatchery production cycle.

ProjectReport of the FAO/WB/UNDP/GEF/FCK Regional Training Workshop on Sturgeon Hatchery Practices and Management - Atyrau, Kazakhstan, 14–19 April 2009 2010
Also available in:
No results found.In recent years, the Governments of the Caspian Sea littoral States have indicated in various occasions in recent years that sturgeon rehabilitation and management in the Caspian Sea is a priority issue for them. A number of national and international activities are carried out to support recovery of sturgeon stocks in the Caspian Sea. Examples of these activities include amongst others: • Studies, stakeholder consultations and workshops organized by the multi-donor Caspian Environment Programme (CEP) funded by Global Environment Facility (GEF), the United Nations Environment Programme (UNEP), United Nations Development Programme (UNDP), the World Bank, the United Nations Office for Project Services (UNOPS) and the European Union (EU). • The new regional United Nations Development Programme–Global Environment Facility (UNDP–GEF) project “The Caspian Sea: Restoring Depleted Fisheries and Consolidation of a Permanent Regional Environmental Governance Framework” (Cas pEco), due to become effective in early 2009. • Capacity building activities in fisheries management by the World Bank Trust Fund for Environmentally and Socially Sustainable Development (TFESSD). • Training activities by the UNDP-GEF project “Integrated Conservation of Priority Globally Significant Migratory Bird Wetlands Habitat: a Demonstration on Three Sites”. • Workshops organized under the United Nations Food and Agriculture Organization (FAO) Technical Cooperation Programme (TCP) project “Capacity building for the recovery and management of the sturgeon fisheries of the Caspian Sea (GCP/INT/3101). The Caspian Fisheries Technical Workshop, jointly organized by the above mentioned FAO TCP project and the World Bank, and held in Rome, Italy, from 28 to 30 April 2008, indicated an urgent need for training in sturgeon hatchery operations. Similarly, the 2008 work programme of UNDP-GEF project “Integrated Conservation of Priority Globally Significant Migratory Bird Wetlands Habitat: a Demonstration on Three Sites” listed among its activities the conducting of training workshops on development of alternative livelihoods and business, including the organization of training workshops on fish farming. In order not to duplicate activities, but reinforce each others strengths instead, the UNDP-GEF project, FAO and the World Bank have teamed-up with the Ministry of Agriculture of Kazakhstan to provide high quality, targeted training to hatchery sta ff from the Caspian Sea littoral countries. -
