Book (series)Sturgeon Hatchery Manual 2013
Also available in:
This Sturgeon Hatchery Manual includes the latest available scientific research findings and experiences and compiles advice given in earlier manuals and handbooks on sturgeon culture and reproduction practices. This document can be considered an update of the Sturgeon Breeding and Rearing Handbook (Chebanov, Galich and Chmyr, 2004), which was published in the Russian language. The Sturgeon Hatchery Manual was prepared in response to numerous requests for practical guidance on this s ubject from the Central Asian and Caucasus region to the Food and Agriculture Organization of the United Nations (FAO). This manual is targeted particularly at sturgeon farmers, sturgeon hatchery operators, hatchery technicians, and fisheries and aquaculture managers involved in sturgeon aquaculture development and the restocking and rehabilitation of sturgeon populations in the countries around the basins of the Black and Caspian seas. It aims to provide a practical handbook of mode rn sturgeon hatchery practices and management. The manual is available in the English, Russian and Turkish languages. The manual starts with a chapter on the taxonomy, biology, distribution and life histories of Azov-Black and Caspian Sea sturgeons. Subsequent chapters discuss the following aspects of sturgeon hatchery practices: hatchery design, collection and transportation of wild broodstock, broodstock management, spawning and gamete processing, fry and fingerling rearing, prod uction of live feeds, the technology of artificial reproduction, ecological- morphological and ethological-physiological express estimation of larval and fingerling (fry) viability, release of fingerlings into natural waterbodies, the formation of domesticated broodstock, basic sanitation and fish health measures, tagging, and early sexing and maturity determination in live sturgeons using ultrasound techniques. The manual also contains an extensive list of references, a list of Acip enseriformes and numerous figures, photographs and tables to support the guidance given on the various hatchery practices -
ProjectReport of the FAO/WB/UNDP/GEF/FCK Regional Training Workshop on Sturgeon Hatchery Practices and Management - Atyrau, Kazakhstan, 14–19 April 2009 2010

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. -

SOUTH PACIFIC AQUACULTURE DEVELOPMENT PROJECT
1990Also available in:
No results found.Tilapia species have been periodically introduced in Fiji since 1949. The main reason for the introduction was to provide animal protein feed to piggeries. In later years, the idea of utilizing Tilapia species for human consumption took root and for the last 10 years Oreochromis niloticus has been the species of choice for aquaculture purposes. Since 1983 fish ponds were constructed in the interior areas of Viti Levu and Vanua Levu for the purpose of providing supplemental animal protein to the protein-deficient inland rural communities. Uncontrolled introduction, accidental or intentional release of Tilapia species in rivers and streams, has led to genetic contamination through free cross-breeding of wild dwelling populations during flooding with the broodstock kept in the hatchery for breeding purposes. Probably due to genetic contamination, the performance of the broodstock deteriorated resulting in poor quality fry. Hatchery-reared fry, once stocked for grow-out in village pond s, reproduced early and the growth rate was low. Appropriate feed composition and preparation represent a constraint for improving yields. In addition, feed components are irregularly available and their cost high due to competition with other animal husbandry practices. Additional constraints to fish farming development are identified in the lack of trained manpower, land tenure and financing initial costs in the country.
