Wildlife biologists are participating in an ongoing study of the American shad — a fish that spends more of its life in the ocean, but returns to fresh water to spawn. During these migrations, shad must travel long distances, and can face barriers like dams. While there has been long-term monitoring of the upstream migration of adult shad from the ocean to fresh water — particularly at major dams — less is known about the impact of dams on juvenile shad as they travel from fresh water to the ocean.
