Book (series)ÊÀ½çÓæÒµºÍË®²úÑøÖ³×´¿ö - 2008 2009经过稳定增长，尤其是过去40年的稳定增长，水产养殖产量将首次占全世界人类消费的水产品的一半。这不仅反映了水产养殖产业的活力，还反映了全球经济的增长以及水产品加工和贸易的持续发展。直到大约一年前，水产养殖和捕捞渔业的产量继续着十年前开始的趋势，没有任何大的变化：捕捞渔业部门有规律地每年出产9000万至9500万吨产品，水产养殖产量快速增长，尽管增速逐渐下滑。 本期《世界渔业和水产养殖状况》专门介绍了可能受到日益关注的渔业和水产养殖的一些方面，包括气候变化、国家管辖区外海洋遗传资源的利用和国际水产品贸易中私人标准和认证计划的增加。本期还着重说明了粮农组织的几项特别研究，包括野生渔业资源作为水产养殖的苗种和饲料、世界对虾渔业回顾以及太平洋海洋捕捞渔业的管理

Book (series)Dams, fish and fisheries (chinese version)
»úÓö¡¢ÌôÕ½Óë³åÍ»½â¾ö·½°¸
2007Also available in:
The four papers presented in this publication address major fishery issues in relation to dams as identified by the World Commission on dams (WCD) and FAO for the purpose of WCD? global reviews on ?ams and Development? Characteristics of river and reservoir fisheries in various regions of the world are reviewed. Production figures for reservoirs in Africa, Asia, Latin America and the Caribbean, as well as for the Commonwealth of Independent States, are mentioned . Also fish production figures fo r large rivers are provided, emphasizing the importance of floodplains for fish production. A non-exhaustive review of the current status of the use of fish facilities at dams throughout the world is presented, with the main target species considered from North America, Europe, Latin America, Africa, Australia, New Zealand, Japan and Asia. Fisheries management capacity and information base requirements are reviewed for the six phases of the dam project cycle, i.e. dam identification, dam design, dam project appraisal, dam construction, dam operation and dam decommissioning. Effective environmental assessment and management coupled with improvements in design of civil engineering structures has made some recent dam projects more fish friendly and environmentally acceptable. The need for drafting legal instruments, which will facilitate modification of dam structures to incorporate mitigation measures and help altering dam operation rules to be more beneficial to fish biodiversity and fi sheries, is emphasized.
