The Alantic salmon (Salmo salar) is a fish of major biological interest and economic importance. Recent years have witnessed major advances in the understanding of the many facets of the biology, ecology and management of this fish. The author, Dr Derek Mills, covers all major aspects of the atlantic salmon throughout its geographical range in the northern hemisphere. There is a great awareness today of the effects on the salmon of afforestation, pollution, acid rain, water abstraction and changing agricultural methods. There has also been a rapid escalation of salmon farming which is beginning to have an impact on wild stocks. The author discusses these issues, also considering the increasing threat of over exploitation of the atlantic salmon.
