A recently completed study using relatively new eDNA technology shows that replacing culverts that might act as fish migration barriers is key to restoring salmon and steelhead in the Pacific Northwest. And, presumably, wherever faulty culverts interrupt salmonid migration. More broadly, however, the study is a herald for the use of eDNA science in restoration work conducted across environments and around the globe.

In a world where the concept of “uncharted” or “exotic” is becoming increasingly elusive, is the bleeding edge frontier of fly fishing not experienced by catching something newer or bigger but through the fusion of fly angling with science and conservation? So says a new short film from Costa Sunglasses, which details the recent effort of a group of scientists, fly anglers, guides, and other volunteers to leverage fly fishing to help researchers learn more about Pacific billfish populations.
