Visiting the hyporheic zone: young <scp>A</scp>tlantic salmon move through the substratum
Summary The hyporheic zone may be a habitat for fish, depending on habitat patch characteristics and interactions with fish behaviour, such as movements. Theory highlights the vertical connection and potentially significant functional role of the hyporheic zone, but actual use of the hyporheic zone...

Summary The hyporheic zone may be a habitat for fish, depending on habitat patch characteristics and interactions with fish behaviour, such as movements. Theory highlights the vertical connection and potentially significant functional role of the hyporheic zone, but actual use of the hyporheic zone by fish is understudied. In replicated factorial field experiments, we investigated movements of (i) young Atlantic salmon of various size ( S almo salar , mean total lengths, 28.3, 51.7, 52.1 and 84.6 mm) through substrata of (ii) different particle size (16–22, 24–60 mm) and (iii) thickness (20, 40, 60 cm), depending on (iv) current direction (horizontal up‐ to downstream, vertical ‘upwelling’) and (v) temperature/season (summer/autumn). In nine experiments, each with different treatments, three replicated 14‐cm‐diameter translucent PVC tubes were used as a proxy for the hyporheic zone and placed in parallel on the bottom in a natural salmon stream.
