Beschreibung
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.
