"Water is of prime importance for all living begins. But we people use this natural resource as dustbin. A great variety of pollutants are produced by human beings daily and many of these reach the aquatic ecosystem directly or indirectly and pose a great threat to aquatic biota. If the present trend continues, most of lentic ecosystems will be converted in aquatic desert. Thus, there is crying need of time for proper aquatic environment management as well as mass awakening right from grass roots level to top ecoplanners, only then our long cherished dream of establishing eco-socialism on this water planet could come true. So, considering the serious problem of aquatic ecosystem, this book is an endeavour to incorporate the relevant and up to date research on aquatic environment.

"This book is the unique compilation of 51 research articles contributed by eminent aquatic biologists which will be immensely helpful for university teachers, research scholars, scientists and for everyone dealing with aquatic environment." (jacket)
