Development of an environmental DNA assay and field validation for the detection of invasive pink salmon Oncorhynchus gorbuscha
Abstract Pink salmon Oncorhynchus gorbuscha was introduced from its native range in the Pacific to Northwest Russia several times since the 1950s. While this species has been regularly observed in rivers in northern Norway since then, there has been an upsurge in the numbers of odd‐year O . gorbusch...
