影響因子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.

Components for Fiber Technologyes Policy. Salmon as an anadromous species is of course different from other fish stocks such as cod, haddock or herring stocks for which the Community fixes annually total allowable catches (TAC) and allocates quotas for Member States. Salmon is not a ‘unitary resource’ nor even a ‘joint stock’ as are these other stocks.

A Survey of Nonlinear ProcessesEdinburgh. The paper was devoted entirely to the illegal catch of Atlantic salmon or as I termed it ‘the Atlantic Salmon Rip-off’. During the course of this presentation I will express the view that very little has changed since then despite a number of positive approaches and actions by concerned g
