    Inland Fisheries Under the Impact of Irrigated Agriculture: Central Asia 1995
    Also available in:
    No results found.

    This publication contains four papers on general and specific aspects of inland fisheries in the arid region of Central Asia. It discusses the management approaches to maintain fish yields in an aquatic environment highly modified by engineering measures required for irrigated agriculture. With the riverine fish stocks greatly diminished and the most valuable fish, such as sturgeon, shovelnose and Aral trout virtually extinct in the Amu-Darya and Syr-Darya, lacustrine fish were introduced to res ervoirs, lakes and irrigation canals where today they represent by far the dominant portion of the total catch. The interconnecting net of irrigation canals has provided perfect migration pathways for redistribution of fish species throughout the Amu-Darya, Syr-Darya and Zarafshan river systems and has contributed, together with exotic fish species introductions, to increasing fish species diversity. In spite of these measures, the fish yields have stayed relatively low. In Uzbekistan the mean f ish yield is about 10 kg/ha/year. Much more could be achieved for enhancement of fisheries through introducing a diversity of management measures. Fisheries management plans have been prepared for the individual Uzbekistan water bodies and await implementation. While the direct impact on the original fish fauna of engineering works required for irrigated agriculture in Central Asia is negative, fisheries management can compensate for the losses in production through species introductions and oth er enhancement measures which would utilize the great diversity of water bodies in the region to their full capacity. Wide exchange of information among the countries of the arid and semi-arid zone through an expert consultation could be a start for developing better strategies for and implementation of fisheries development in irrigated areas.

    AQUASTAT Survey- 2011
    2012
    Also available in:
    No results found.

    This AQUASTAT report presents the most recent information available on water resources and their use in the 22 countries in the Southern and Eastern Asia region. Clearly it has an emphasis on agricultural water use and management. But in addition it contains the relevant tables and maps, and a regional synopsis emphasizing the particular characteristics of this large and diverse region. It also analyses the changes that have occurred since the first survey in 1999. Finally it gives a more detail ed description of four transboundary river basins in the region, highlighting the different levels of cooperation and the agreements between countries located in the same river basin: the Ganges?Brahmaputra?Meghna basin, the Indus basin, the Mekong basin and the Salween basin.
