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. Departmen...
