Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Keith Culver and David Castle Introduction Aquaculture is at the leading edge of a surprisingly polarized debate about the way we produce our food. According to the United Nations Food and Agriculture Organization, aquaculture production has increased 8. 8% per year since 1970, far surpassing productivity gains in terrestrial meat production at 2. 8% in the same period (FAO 2007). Like the ‘green revolution’ before it, the ‘blue revolution’ in aquaculture promises rapidly increased productivity through technology-driven - tensi?cation of aquaculture animal and plant production (Costa-Pierce 2002; The Economist 2003). Proponents of further aquaculture development emphasize aq- culture’s ancient origins and potential to contribute to global food security d- ing an unprecedented collapse in global ?sheries (World Fish Center; Meyers and Worm 2003; Worm et al. 2006). For them, technology-driven intensi?cation is an - dinary and unremarkable extension of past practice. Opponents counter with images of marine and freshwater environments devastated by intensive aquaculture pr- tices producing unsustainable and unhealthy food products. They view the promised revolutionasascam,nothingmorethanclever marketingbypro?t-hungry ?shfa- ers looking for ways to distract the public from the real harms done by aquaculture. The stark contrast between proponents and opponents of modern aquaculture recalls decades of disputes about intensive terrestrial plant and animal agriculture, disputes whose vigor shows that the debate is about much more than food production (Ruse and Castle 2002).
