Norway Salmon Farming Pollution Impacts Fjords

Recent analysis shows that salmon aquaculture in Norway releases massive amounts of nitrogen, phosphorus, and organic carbon into coastal waters. This waste is comparable to the untreated sewage of millions of people, leading to oxygen depletion in deep waters. Environmental authorities are now rejecting new farm applications in areas like Hardangerfjord to prevent further ecological collapse. The pollution triggers algae blooms that consume oxygen, threatening local wildlife and the fishing economy.
