"The subject of managing freshwater ecosystems is gaining attention in view of the increasing importance of water for multiple uses and at the same time to save these resources from problems of pollution, eutrophication, etc.

The present book is a humble attempt in this direction for compiling useful information on different basic and applied aspects of management of freshwater ecosystems for the benefit of readers. The book comprises carefully selected topics on various aspects of aquatic systems and their management with particular emphasis on freshwaters. The authors of various chapters are senior scientists having wide exposures and experience for several years, which is clearly reflected in their contributions. It is hoped that this publication would generate adequate attention at various levels for further enhancement of scientific and technical inputs for management of freshwater ecosystems." (jacket)
