Idaho Fish Conservation and Research

The video explores the diverse fish species in Idaho, highlighting the distinction between native and exotic fish. It discusses the challenges native fish face, such as habitat loss and competition from non-native species. The importance of fish migration and identification is emphasized, along with the impact of dams on fish populations. The video also covers research efforts to protect endangered species like the Chinook salmon, using technologies like PIT tags to track their journeys. Finally, it provides resources for further learning on the Science Trek website.
