September 1, 2026 — Bipartisan legislation introduced this month by the co-chairs of the U.S. Senate Oceans Caucus relies on environmental DNA (eDNA) techniques pioneered by Cornell researcher David Lodge, professor of ecology and evolutionary biology and past director of the Cornell Atkinson Center for Sustainability.
The Fisheries Science Modernization Act would direct the National Oceanic and Atmospheric Administration (NOAA) to incorporate eDNA tools into their assessment surveys of fish stocks – assessments that inform how many fish can be harvested by commercial and recreational fishers. Eight Republican, Democratic and independent senators co-sponsor the legislation, and multiple fishing industry and environmental protection organizations support it.
“When I started testing eDNA 17 years ago, I was interested in detecting rare species, such as emerging invasive species and endangered species,” Lodge said. “The focus of this legislation is quite different. Here, it’s not just about detecting whether a Pacific hake exists, it’s about estimating how many hake there are, based on how many distinct pieces of hake DNA you can find. It’s pretty astonishing to me that we in the scientific world working on eDNA have come this far, this fast.”
