A dispute among European nations over the management of pelagic stocks in the Northeast Atlantic, particularly mackerel, herring, and whiting, has persisted since 2010, leading to the inability to reach a comprehensive agreement on mackerel quotas and allegations of overfishing. Despite shared scientific agreement on fish stock management, countries have consistently fished more than recommended by the International Council for the Exploration of the Sea (ICES), with collective overfishing ranging from 66 to 86 percent between 2010 and 2022. The disagreement has been exacerbated by Brexit and has led to the loss of the Marine Stewardship Council (MSC) Blue Label for sustainable fisheries for some countries, due to unregulated quota increases. The European Commission has urged Norway and the Faroe Islands to return to a previous sharing arrangement, but their refusal has prompted the EU to establish its own quota shares.
