Norway’s Salmon Farming Dilemma (Encore)

Norway is the largest exporter of salmon in the world. And while some of those fish are wild-caught, many are raised in “fish farms”- large cylindrical pens made of nylon in the open water. Sometimes these farmed fish escape, mixing with the local population and causing ecological issues. In a story we first brought you in October, we see farmed fish in a Norwegian fjord and hear about potential solutions to the problem.
