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
