"Limnology is the study of Inland waters. This comprises the biological, chemical, physical, geological, and other attributes of all inland waters (running and standing waters, both fresh and saline, natural or man made). This includes the study of lakes and ponds, rivers, springs, streams and wetlands. In recent years the desirability of an approach to the subject matter of limnology through introductory consideration of the principal physical and chemical factors operative in natural, unmodified water has been emphasized. Certain facts of physics and chemistry, particularly those pertinent to limnology, must be clearly in mind before the biological phenomena which involve them can be studied. Thus a satisfactory understanding of aquatic life requires a knowledge not only of the organisms themselves but also of those external influences  which directly or indirectly affect them. 

The book covers the fundamentals of limnology. In this book, the author has used the term limnology, to included all forms of inland waters, running or standing. Original data from the researchers of the author and his associates have been incorporated into most sections of the book.

The whole book is presented in five parts. Part I deals with inland waters, lakes, their origin and diversity. Part II focuses on nature of inland water environments. This chapter includes both physical and chemical conditions and related phenomena. The factors which control physical and chemical conditions and organism (plankton, bacteria, fungi, algae) found in the aquatic environments have been discussed in part III. Details of some special types of lentic environments (ponds and bogs lakes) have been provided in part IV. Part V deals with lotic environments with special reference to running waters. 

The book, besides limnologists, will be useful for ecologists, environmental biology, fishery professionals, scientist and research workers teachers and post-graduate students." (jacket)
