The upper Missouri River basin in the northwestern US contains disjunct Arctic grayling (Thymallus arcticus) populations of conservation concern. To assist efforts aimed at understanding Artic grayling distribution, we developed a quantitative PCR assay to detect the presence of Arctic grayling DNA in environmental samples. The assay amplified low concentrations of Arctic grayling DNA consistently, and did not amplify non-target species, including sympatric salmonid fishes.
