Chapter 1-5 describe diversity of entomo-fauna with special reference to lepidoptera, hemiptera and coleopteran from Uttarakhand, J&K and Gujarat. Chapter 6 to 12 are devoted to various aspects of aquatic biodiversity with special reference to plankton, rotifers, shell fishes, freshwater fishes their management and physical integrity of the hill streams, from different parts of the country.
