Abstract
Pink salmon are native to the North Pacific region but have spread due to introductions in north-west Russia. More than 800 000 pink salmon have been recorded in Nordic countries since 2017. The abundance has massively increased, with 50 times more pink salmon recorded in 2023 than 2017. Norway, including border rivers to Finland, has received the largest numbers, thereafter Greenland and Iceland. The areas with high abundances of pink salmon are expanding. Despite the massive invasion of pink salmon, and the risk of further spread within the Nordic region, the knowledge of impact on native salmonids and ecosystems is still poor, mainly due to lack of research funding. Mitigation efforts have been greatest in northern Norway by removal of pink salmon in rivers. Most of the Nordic countries seem not to have risk analyses or developed management plans to meet a potential increase in abundance of pink salmon.
