Detection and identification of lampreys in streams using environmental DNA

Summary

Control of sea lampreys in the Great Lakes requires accurate assessment of the distribution of this species in natal tributaries and the ability to distinguish sea lampreys from the four lamprey species that are native to the Great Lakes; two of these native species are of conservation concern. Environmental DNA (eDNA) has been used to assess the diversity and abundance of aquatic species by detecting the DNA of an organism in the water instead of locating the organism itself. We developed PCR-based assays to distinguish among the four ‘species’ of Great Lakes lampreys (sea, American brook, chestnut, and silver/northern brook lampreys), and employed these in the development of efficient and cost-effective environmental DNA (eDNA) methods.
