Acoustically derived fine-scale behaviors of juvenile Chinook salmon (Oncorhynchus tshawytscha) associated with intertidal benthic habitats in an estuary
Given the presumed importance of benthic and epibenthic estuarine habitats in Chinook salmon ( Oncorhynchus tshawytscha ) smolt growth and survival, resource managers would be well served by an improved understanding of how smolts use such habitats. A cabled acoustic positioning system was used to p...
