The zooplankton is one of the most fascinating and diverse assemblages of animals known to biologists. Zooplankton play a vital role in the process of energy transfer between various trophic levels in estuarine and marine ecosystem and acts as secondary producers. Studies on the zooplankton associated with such ecosystems assume importance in order to understand their overall functioning. In this context, the importance of zooplankton in their myriad roles for example as secondary producers, gains much significance. This book has been written covering various aspects of zooplankton in order to cater to the needs of students, research scholars and teaching faculty in colleges and universities. A book of this kind will be of immense use to all those who study or teach Aquatic ecology, Marine Biology, Oceanography and Hydrobiology. Since this book, contains detailed methodologies to study varies aspects of zooplankton, it creates a vivid and essential reference text for all those interested in zooplankton. Not only this, the present book will also be helpful for scientists, as well as limnologists and marine biologists for aquatic impact assessment and management.
