Iceland, Open-Net Fish Farms, and the Final Frontier for Wild Atlantic Salmon

In the last 20 years, the expansion of salmon farming in open-net pens has led to the loss of half the wild salmon population in Norway. On average, 200,000 farmed fish escape from open-net pens and many of them swim up rivers in Norway and breed with wild stocks, contributing to species decline. According to conservation groups, the same method of farming is also responsible for the collapse in salmon and sea trout populations in the West Highlands and Islands of Scotland. By Mădălina Preda
