Passage through submersible and Archimedes pumps results in decreased migration survival in coho salmon yearlings
Flood-control pumpstations compromise connectivity and survival for migratory fish globally, yet field evaluations of modern "fish-friendly" designs remain scarce. We evaluated out-migration survival and behavior of yearling coho salmon (Oncorhynchus kisutch) entrained through an open-Archimedes screw station (Hammersley) and a conventional radial station (Barrowtown) in the lower Fraser River…
