Delivering a minor electric shock into a stream to reveal any fish lurking nearby may be the gold standard for detecting fish populations, but it s not much fun for the trout.
Scientists at Oregon State University have found that sampling stream water for evidence of the presence of various species using environmental DNA, known as eDNA, can be more accurate than electrofishing, without disrupting the fish.
It s revolutionizing the way we do fish ecology work, said Brooke Penaluna, a research fish biologist with the U.S. Department of Agriculture Forest Service who also has an appointment in OSU s Department of Fisheries and Wildlife. You can identify species from a bottle of water using genetic tools. When you go out to the site, I can tell you what s in that stream just based on ....

Can t replace full surveys, but can complement, ease disruptions
CORVALLIS, Ore. (KTVZ) Delivering a minor electric shock into a stream to reveal any fish lurking nearby may be the gold standard for detecting fish populations, but it’s not much fun for the trout.
Scientists at Oregon State University have found that sampling stream water for evidence of the presence of various species using environmental DNA, known as eDNA, can be more accurate than electrofishing, without disrupting the fish.
