Understanding summertime thermal refuge use by adult Atlantic salmon using remote sensing, river temperature monitoring, and acoustic telemetry.
Adult Atlantic salmon return to natal rivers several months before spawning, and during summer, can be subjected to temperatures that exceed their upper temperature tolerance limits. Salmon use thermal refuges to minimize exposure to high temperatures, but little information exists regarding behavio...

Adult Atlantic salmon return to natal rivers several months before spawning, and during summer, can be subjected to temperatures that exceed their upper temperature tolerance limits.
