William Shearer, an eminent biologist of international reputation, has devoted a lifetime to studying the Atlantic salmon. His book describes the life history of the Atlantic salmon, in the light of the results of the last thirty years' research. In addition, it details all aspects of the fisheries which exploit this valuable resource - their ownership and management, the different gears, past and present catches, the high seas fisheries and their possible effects on home-water stocks - and discusses the present status of the Atlantic salmon with special reference to Scotland. The results and implications of the author's North Esk research are discussed along with the effects of fish farming on wild stocks and the future of the salmon.
