Institution: Report of the Northwest and Alaska Fisheries Center

Swimming stamina, stride length, and post-test survival were assessed in seawater for both smolt and parr revertant coho salmon Oncorhynchus kisutch.  Parr revertants had lower swimming stamina (-20%), lower stride efficiency (-20%), and greatly reduced 96-h post-test survival (-89%) compared to smolts with the same residence time in seawater.
