Book Description
This publication reviews the potential for fisheries production from irrigation canals. It deals with the subject under the following major headings: engineering aspects of irrigation systems; factors limiting fish production in canals; weed growth and associated problems in irrigation canals. Cage culture in irrigation canals is presented in case studies for Indonesia, Egypt and Thailand, and pen culture in China. Both cage and pen culture are considered to be the most suitable forms of aquaculture in irrigation canals. Fish can be profitably and successfully reared in irrigation canals to control unwanted aquatic weed growth, and there is some potential for the use of fish to control vectors and hosts of waterborne diseases. Amongst the constraints, levels of pesticides in fish tissues cultured in irrigation systems could be a problem in the development of foodfish production in irrigation canals. The major constraint to aquaculture development in such systems is that a continuous, preferably constant, flow of water is required throughout the culture period and this is not available in many irrigation systems.

Book Description
This publication contains 12 papers on the present use of irrigation systems for fisheries of the countries in the arid belt of Asia, covering areas in China, India, Iran, Kazakhstan, Kyrgyzstan, Mongolia, Pakistan, Turkey and Uzbekistan. Whilst some countries are well advanced in use of irrigation systems for fish production, others are experiencing major difficulties arising from recent political and economic changes.

Book Description
The Mekong River has been a main source of conquest, conflict, and cooperation in the Southeast Asian region. Much has been written on the vital and critical importance of the Mekong River fresh water to the sustainable economic development of the Mekong Delta. This book selects the Mekong Delta as a case study of regional cooperation for water and food security for not only for Vietnam but also for the world in a new century of global economy. It focuses not only on the Mekong Delta as an integral part of the River but also on Can Tho City and its 12 provinces that produce over 50 percent of the country’s rice output and 60 percent of total fishery output. The book takes a micro approach to examine how each province is adapting to the twin threats of mainstream dams construction and climate change, reducing fresh water flows and increasing saline infusions on its present and future economy. Finally, it reviews the roles of international institutional arrangements, namely the Mekong Committee and the Mekong River Commission, in promoting regional cooperation among the riparian states for political and economic development of the Mekong Delta.
