This book brings together research into the process of stream acidification and its impact on Welsh surface waters, carried out over the past decade or so. It is perhaps surprising that not until the 1980's was clear evidence of stream acidification assembled. In Wales, concerns over pollution had focused water quality sampling principally on the areas of traditional heavy industry and large urban popula tions served by inadequate sewerage systems and sewage disposal arrange ments. Mistakenly, it had been assumed that, with its prevailing westerly winds, Wales would receive precipitation substantially unpolluted by the industrial and urban emissions from Britain and mainland Europe. Assurance of the high quality of Welsh upland streams, the traditional nursery ground of salmonids, was eroded particularly by studies in the vicinity of Llyn Brianne reservoir in the catchment of the River Tywi of Central Wales. These demonstrated a clear correspondence between the biological quality and fisheries of streams in the catchment and aspects of stream chemistry, par ticularly pH, aluminium and calcium on the one hand, and catchment land use on the other. It is salutary to record that the first signals were of an inexplicable failure of the runs of migratory salmonids into the upper catchment, occupied by the Llyn Brianne reservoir and its influent streams, and the failure to restore the fishery by re-stocking with eggs and fry. Only then did the significance of the recent decline in some other upland lake and reservoir fisheries in Wales become apparent.

The proceedings of a special technical session dealing with the addition of Ca based materials to waters and soils for the purpose of restoring or enhancing fisheries in acidified waters are contained in this volume. The session was part of the North American Fisheries Society's annual meeting sponsored by the Water Quality Section of the Society. While the concept of liming is not new, the extent of the recent research, demonstrations and applications reported at the conference is enlightening. Six countries are represented by government, state and private sector participants. The scope of activities reported in the following 23 papers range from the simple to the very complex addition of liming materials to ponds, lakes, streams and watersheds. This volume of presentations is broad and impressive as are the methods used in the actual application of the neutralizing materials. Those programs that are demonstration application oriented are deploying techniques that are either new or modifications of existing technology.

In the decade since the first edition of this book was published advances have been made in our knowledge of the fresh waters of the world, espe cially in understanding many of the processes involved in their functioning as systems and in countering the problems created by human activities. New problems too, many of an international nature, have loomed during this period-of which global warming and the acidification offresh waters in many parts of the world are notable examples. In addition, much has now been published concerning the aquatic flora, fauna and ecology of previously poorly known geographic areas, notably Australasia. The second edition of this book is a revision which updates the text in the light of recent advances in our knowledge of freshwater biology. Inevitably, in an elementary volume such as this, the treatment of many of the basic principles and processes remains the same. However, several new sections are included covering a range of topics such as acid deposition and the acidification process, bacterial decomposition and aquaculture. The book includes many new references and suggestions for up-to-date reading in particular topics. The objective of the second edition remains the same as that of the first. It is intended as a basic introduction to the major aspects of freshwater biology at a level suitable for undergraduates. It should also prove useful, as apparently did the first edition,Jo professional workers in related fields, e.g. water engineers and chemists, aquaculturists and planners.

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
