A report from the Sunstone Institute reveals that Norwegian salmon farms release nitrogen, phosphorus, and organic carbon into fjords at levels equivalent to the untreated sewage of millions of people. This nutrient runoff contributes to eutrophication and oxygen depletion in critical water systems like Sognefjord. While the industry argues that current production stays within nature's carrying capacity, regulators have already begun rejecting new farm applications to prevent further ecological collapse. The findings highlight a growing conflict between aquaculture growth and marine conservation.
