DOWNLOAD EBOOKThe last major synthesis of our knowledge of fish migration and the underlying transport and guidance phenomena, both physical and biological, was "Fish Migration" published 16 years ago by F.R. Harden Jones (1968). That synthesis was based largely upon what could be gleaned by classical fishery-biology techni.ques, such as tagging and recapture studies, commercial fishing statistics, and netting and trapping studies. Despite the fact that Harden Jones also provided, with a good deal of thought and speculation, a theoretical basis for studying the various aspects of fish migration and migratory orientation, progress in this field has been, with a few excepti.ons, piecemeal and more disjointed than might have been expected. Thus we welcomed the approach from the NATO Marine Sciences Programme Panel and the encouragement from F.R. Harden Jones to develop a proprosal for, and ultimately to organize, a NATO Advanced Research Institute (ARI) on mechanisms of fish migration. Substantial progress had been made with descriptive, analytical and predictive approaches to fish migration since the appearance of "Fish ~ligration." Both because of the progress and the often conflicting results of research, we felt that the time was again right and the effort justified to synthesize and to critically assess our knowledge. Our ultimate aim was to identify the gains and shortcomings and to develop testable hypotheses for the next decade or two.

DOWNLOAD EBOOKThe Yellow River basin, located in the semi-arid and arid climate zones in northern China is confronted with serious problems of water deficit as well as water pollution. Due to increasing population levels, rising living standards, increasing pressure of expanding irrigation areas and developing industries in the basin, efficient water resource allocation has become a pressing issue here. On the surface it appears to be domestic, but in reality the problem is one of international proportions because it may impact other countries through trade. Development in the basin is restricted by acute water shortage, salinity damage and pollution. There are many scenarios for the allocation of water resources. One extreme is industry-oriented and the other is agriculture-oriented. The allocation between upstream and downstream is also another issue. In order to understand the current state of water resources in the basin and to provide a way of thinking about the issues, this book systematically explains the methods of modeling, mechanism of water circulation on each element and several technologies for water saving. It also introduces cutting-edge research results of the five-year project "improving the sustainability in utilizing and controlling water in the Yellow River basin" sponsored by Japan Science and Technology Corporation (JST).
