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.

Salmon at the Edge covers, in depth, the problems faced by wild Atlantic salmon and sea trout in estuaries and coastal zones, and in their early weeks at sea. The book also reflects the current precarious state of many migratory salmonid populations and the need for new approaches to a number of threats to these populations. Generated from papers given at the landmark Sixth Atlantic Salmon Symposium, held in Edinburgh, UK, Salmon at the Edge contains a huge wealth of information on such important topics as the impact of salmon farming, the behaviour of post-smolts in their early migration and their vulnerability to by-catch, and the use of nutrient enrichment and habitat enhancement to increase production of juvenile salmonids. With chapters written by internationally-known and respected authors, and including a message of support from His Royal Highness The Prince of Wales, this important volume is essential reading for all those involved with salmonid fishes, including fish biologists, fisheries scientists and managers, environmental, marine and freshwater scientists, and personnel involved in salmon aquaculture. Libraries in all universities and research establishments where these subjects are studied and taught should have copies on their shelves. The Sixth Atlantic Salmon Symposium, from which chapters in this book have been generated, was organised by The Atlantic Salmon Trust and The Atlantic Salmon Federation, and was published with the financial support of The Fishmongers’ Company and Scottish and Southern Energy. Derek Mills of The Atlantic Salmon Trust, Pitlochry, Perthshire, UK has many years of research, writing and editing experience in salmon biology and fisheries
