Coastal infrastructure alters behavior and increases predation mortality of threatened Puget Sound steelhead smolts

Megan Moore & Barry Berejikian
Fundamental movements of migratory species can be substantially influenced by marine habitat disruptions caused by coastal infrastructure. The Hood Canal Bridge (HCB) spans the northern outlet of Hood Canal in the Salish Sea, extends 4.6 meters (15 ft) underwater, and forms a partial barrier for steelhead migrating from Hood Canal to the Pacific Ocean. Spatial mark-recapture survival models using acoustic telemetry data indicate that only 49% (2017; 95% CI = 40, 58%) and 56% (2018;...
