Tracing fish products from sea to consumer is of paramount importance for securing sustainable fisheries and consumer protection. Genetic methods have shown great promise for geographic origin assignment. However, application in marine fish has been hampered by the finding of minute genetic differences among populations and inadequate fisheries governance. We introduce a new concept for population assignment of marine fish by identifying gene-associated markers subject to selection. Genetic markers with highly elevated genetic differentiation were identified in four commercial marine fish on a pan-European scale. These markers provided 93-100% correct origin assignment in policy-driven case studies at various geographical scales. Forensically validated publicly available databases of such high resolution markers provide powerful new tools to fight illegal, unreported and unregulated fishing and mislabelling.
