From the preface: "The study of river ecology has gained immense importance because of the multiple use of river waters. Almost all major rivers of India have become highly polluted. Even the Ganga, with high self-purification capacity, is among India's most polluted rivers. River Hugli which originates from Ganga experiences considerable human activities of various kinds along its course including domestic, commercial, agricultural and industrial activities. As a result, different types of waste materials enter the river continuously altering its water quality and are bound to affect the living resources, i.e., animals and plants occurring in the river water. The water quality of this river in particular and the habitat in general have become somewhat inhospitable to shelter the organic diversity. The rich variety of flora and fauna, which has so long sustained, have now become threatened. In view of the above facts, a comprehensive plan had been in mid 1980's undertaken by the Central Ganga Authority to restore the purity of the river water which will obviously help in the preservation of its natural living resources. A nationwide effort to restore and maintain the water quality got underway with the passing of Water Prevention and Control of Pollution Act in 1974. "In an effort to understand and evaluate the hydrobiological status of Hugli estuary in and around Calcutta metropolis, a comprehensive biomonitoring 136 pp.

From the Preface During the last few decades lakes allover the world have become the focus of environmental investigations. The increased human activities including excessive dumping of organic as well as non biodegradable wastes have brought about drastic changes in lake environment in India and especially Calcutta now Kolkata. The urban lakes in Calcutta are in fact predominantly plagued with problems pertaining to poor water quality prolific growth of weeds and loss of bio eco aesthetic values. Keeping in view of these threats to Rabindra Sarovar (RS) Government of India has declared this lake as a National Lake under the National Lake Conservation programme (NLCP). The basic objectives of such a designation to RS are to improve its environment along with prevention of pollution catchment area treatment desilting deweeding as well as research and development studies on floral and faunal activities and related ecological aspects. So as a part of the NLCP present investigations were undertaken on two major urban lake environments viz. Rabindra Sarovar and Subhas Sarovar which are located in the heart of the city Calcutta. A comprehensive study of physico chemical characteristics of water and sediment and benthic fauna was undertaken in the present research to cover a multitude of impairments of the aquatic system like presence of nutrient salts and estimation of benthic condition. Herein the physico chemical status of the lake ecosystem is described covering a wide spectrum of parameters while the study on the benthic fauna emphasized their importance as an effective tool for supplementing the physico chemical information on the lakes. Various biological indices were calculated to reflect the overall condition of the aquatic system by a single index value. On the other hand statistical analyses were done to elaborate the inter relationships between the selected abiotic factors and benthic components of the lake so that the available information may clearly and convincingly demonstrate the health of these two lakes. 120 pp.

From the Preface This handbook is a continuing collaborative effort of documenting catalogue and State Fauns Series to provide a true identification manual related to Myxosporean Parasites of Fishes that is up to date dependable exciting and challenging. Its major goal is to emphasize the central role of detection and determination of piscine Myxosporean Parasite occurring in India that occupied a paramount position in aquaculture and fisheries. With the growing need from traditional to intensive and semiintensive piscicultural practices the very survival of commercially important cultivated fishes is at stake because of easy spread of Epizootic Diseases in organically rich crowded freshwater pond ecosystem. It is thus imperative that fish farmers fishery entrepreneurs and researchers of fisheries and pathobiology be informed and acquainted about diagnosis of the diseases identification of the species as well as parasitological and pathological issues. This handbook is useful not only for students and researchers but also for fishery owners with only a minimal background in biology to aware and facilitate recognition of Myxosporeans and their pathogenic effects. 302 pp.
