The volume focuses on the ecological functioning of rivers, which has received less attention than functioning of lakes and reservoirs. The selected papers cover a large range of topics relating to aquatic communities, eutrophication, nutrient dynamics and organic pollution, erosion and sediment transport, and fate of micropollutants at the basin scale. Integrated approaches developed in order to study the ecological functioning of fluvial systems perturbed by human activity are presented. This functioning is analysed from the point of view of fundamental research, but insights into system management are not neglected. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, and water surface pollution, to postgraduate students, to the institutions involved in water resource management, and to the drinking water and waste water treatment industries. It draws information from many large river systems in the world.

Up-to-date information, knowledge and research in progress in scientific fields related to natural production of juvenile Atlantic salmon and some other ecologically similar fluvial salmonids is contained in the 25 papers and 12 abstracts contained in this publication, which were prepared for an international symposium held in St. John's, Newfoundland. Studies relate to stream ecology, invertebrates and predators, habitat improvement, competitive effects, behaviour and dispersal, habitat and production of juvenile salmon, population dynamics and relationships of juvenile salmon estimates to smolt yields. A list of participants at the conference is also provided.

At present fishing for salmon in Norwegian home water is carried out with drift nets, bag nets, bend nets, lift nets and stake nets in the sea, and mainly by rods in the rivers. Catch statistics have been collected since 1876, but reliability of the statistics is questionable. The rates of exploitation on many Norwegian salmon stocks are very high, and data are presented and discussed for River Laerdal, River Eira and River Imsa stocks. As a result of this heavy exploitation with nets, the frequency of net-marked salmon entering rivers is high especially for griIse, although most net-marked salmon are only slightly damaged. It is suggested that mortality of salmon that are net-damaged hear or in brackish water is relatively small compared with salmon that escape from nets on the high seas. Some possible effects of selective fishing are also discussed. 159 Status of Exploitation of Atlantic Salmon in Norway REFERENCES Anon. (l985a) Salmon and sea trout fisheries 1984.

From reviews of the hardback edition:- No matter how experienced a salmon man the reader is, I cannot believe he will study this extremely informative book without learning a great deal and gaining much enjoyment from doing so.The biology and life of the salmon . . .are all dealt with in a most interesting manner . . .Highly recommended. A book not to be read just once, but often to be consulted.; This book is dedicated to Salar the Salmon and what a tribute it is to this unique fish. Supporters of the Trust would be wise to purchase this book and to keep it on the shelf for future reference. - Atlantic Salmon Trust Progress Report
