Event Title
Rock(fish) around the clock: depths and activity levels of threatened Puget Sound rockfish
Presentation Abstract
Rock(fish) around the clock: depths and activity levels of threatened Puget Sound rockfish The movement and dispersal of individual organisms and groups of organisms drive many ecological and evolutionary processes and are important considerations for conservation and management. Yelloweye rockfish (Sebastes ruberrimus) in Puget Sound, WA are listed as threatened under the Endangered Species Act (ESA) and have critical habitat designations, however little is known about their fine-scale movements in this area. The objectives of this study were to quantify patterns of vertical movement and activity level for yelloweye rockfish at hourly and seasonal scales and determine whether environmental covariates, such as currents, ocean temperature, and dissolved oxygen (DO) concentration, affect these patterns. We tagged 15 yelloweye rockfish with acoustic transmitters and monitored their movements in three acoustic receiver arrays in Hood Canal, WA from October 2016 to October 2017. Each transmitter was outfitted with a pressure and accelerometer sensor that transmitted the depth (m) and activity level (m/s
