The mass production of salmon in Norway, the world’s largest producer, is facing alarming challenges, with 65 million farmed salmon dying before slaughter in 2023. Factors contributing to this high mortality include parasitic sea lice and unsustainable farming practices. Activists, including Greenpeace’s Iris Menn, criticize mass farming methods, while retailers like Coop and Migros continue to promote discounted salmon. The ASC certification, aimed at ensuring better fish welfare, is also under scrutiny. The situation affects not only farmed salmon but also wild populations, raising concerns among marine biologists.
