Reviews advances in the understanding of the biology, ecology and management of the Atlantic salmon throughout its geographical range, and examines the effects on salmon of afforestation, pollution, acid rain, water abstraction and changing agricultural methods. The rapid escalation of salmon farming with its impact on wild stocks is analyzed as is the increasing threat of over-exploitation on both the open seas and in home waters.

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...
