Dams interrupt river connectivity and disrupt fish migrations. We used telemetry to study the migratory movement patterns of adult American shad, sea lamprey, and Atlantic salmon on the Penobscot River, Maine after dam removals and other passage improvements had occurred. We also studied scale formation of marine-stage Atlantic salmon raised in marine net pens, the findings from which could be relevant to captive rearing efforts.
American shad now have access to the majority of their historic spawning habitat, contingent on passage the first main-stem dam (Milford Dam). We found that habitat upstream of dams was infrequently accessed, and first …
