Environmental DNA concentrations are correlated with regional biomass of Atlantic cod in oceanic waters

Abstract Environmental DNA (eDNA) has emerged as a powerful approach for studying marine fisheries and has the potential to negate some of the drawbacks of trawl surveys. However, successful applications in oceanic waters have to date been largely focused on qualitative descriptions of species inven...
