This book provides an original limnological investigation of a unique, shallow, man-made, tropical freshwater lake. The book covers details investigation on various physico-chemical parameters and their interactions, structure of planktonic community and their interactions, species diversity, biomass, primary and secondary biochemical composition and calorimetry of netplankton community, etc. The influence of polyphenolics group on the quality of food particles and on the energy reserved of freshwater planktonic community adds a new dimension in this book. The book provides an extensive research on freshwater ecosystem that will be useful to those pursuing advance level courses on limnology, especially to the researchers working in the area of Limnology/ Ecology and Environment/ Fisheries, advance level post graduate students, administrators and consultants interested in management and research of freshwater ecosystems.
