Book Description
Increasing urbanization, industrialization and green revolution leads to the continued addition of pollutants to the aquatic environment. Aquatic organisms serve as a biological indicator to monitor the aquatic pollution. Pollution may induce certain biochemical changes in aquatic organisms and before the drastic cellular and systematic dysfunctions manifest themselves, appropriate biochemical parameters related to proteins, lipids and glycogen etc. could be used effectively to known the gravity of the situation and to check it at the initial stage itself (Aldridge, 1983). Studies on energy metabolism are concerned in the way in which the major carbohydrate, lipid and proteins fuels are used by a organism for energy production. In invertebrates, changes in the biochemical constituents are pronounced which are cyclic in reproduction, since a great amount of energy, must be channelized to the gonad during reproduction. This is reflected in deposition or depletion of the nutrients with advent or departure of the reproductive period (Lambert and Dehnel, 1974). If molluscs are classified according to the types of accumulated nutrients, then Amphineura’s are lipid oriented (Giese,1966), lamellibranchs may be considered to be polysaccharide oriented (Martin,1961 and Martin and Gaddards,1966), some gastropods appear to possess a polysaccharide-oriented metabolism, while others have lipid-oriented metabolism system and cephalopods apparently do not preferentially accumulate nutrients (Chaige, 1933 and Giese, 1959).

Book Description
This book deals with recent and upcoming technologies of breeding freshwater ornamental fish. It covers in detail areas such as status, breeding techniques, food and health management and marketing of freshwater ornamental fishes. There is a separate chapter on breeding of indigenous freshwater ornamental fishes. Emphasis is given on national and international legislation related to ornamental fish export and import. The book contains a useful chapter on the importance and role of ornamental plants and accessories. Aquarium making, decoration, water quality management and maintenance have also been well explained for hobbyists. This title has been co-published with NIPA.

Book Description
The existing literature on limnology and fisheries of Indian reservoirs has been reviewed by covering more than 100 reservoirs located in various parts of the country. An assessment of environment-mediated production functions of reservoirs has been attempted. Since the ecosystem processes in reservoirs belonging to different geo-climatic regions exhibit wide variations depending on meteorological, morphometric and hydro-edaphic features of the impoundments, an effort has been made to gauge the influence of these abiotic variables on the production dynamics. Authentic information on water areas under different categories of reservoirs has been collected and interpreted in respect of all the Indian States. An attempt has also been made to resolve the anomalies pertaining to classification and nomenclature to the extent possible. Various fisheries management norms followed in the reservoirs of the country including the selection of species for stocking, stocking rate and introduction of exotic species have been reviewed. Indian reservoirs have been stocked with the Indo-Gangetic carps for many decades and the impact of this stocking has been assessed in terms of fish production and the indigenous faunistic diversity.

Book Description
Biochemistry of Parasites, Second Edition presents the biochemical aspects of parasitology. The topics covered in the book include inorganic substances; carbohydrate relationships of parasites; parasitic metabolism of carbohydrates and transport mechanisms; distribution of lipids in the bodies of parasites; and disturbances in the host's protein metabolism during parasitic infections. Parasitologists and biochemists will find the book interesting.

Book Description
This book is divided into three sections. The first is concerned with the ecological nature of some of the problems faced by animals as a particular consequence of their adopting a parasitic mode of life, and the strategy, rather than the tactics, of their solutions to these problems. The second section is concerned with the specific problems and difficulties posed by the major organs and tissues occupied by parasites, and the tactical solutions adopted by parasites in each of these habitats that enable them to cope with and overcome these difficulties. The third section is concerned with population ecology, and emphasises that although individual parasites have to face and overcome particular problems, parasitism is essentially a dynamic relationship between two species populations.
