Organisms use a variety of environmental cues to orient their movements in
three-dimensional space. Here, we show that the upward movement of young
Chinook salmon (Oncorhynchus tshawytscha) emerging from gravel nests is
influenced by the geomagnetic field. Fish in the ambient geomagnetic field
travelled farther upwards through substrate than did fish tested in a
field with the vertical component inverted. This suggests that the
magnetic field is one of several factors that influences emergence from
the gravel, possibly by serving as an orientation cue that helps fish
determine which way is up. Moreover, our work indicates that the
Oncorhynchus species are sensitive to the magnetic field throughout their
life cycle, and that it guides their movements across a range of spatial
scales and habitats.
Putman-Scanlan_RawDataFish were tested in one of three magnetic
treatments. Each column represents results for a given treatment. Each
cell represents the height a single fish swam within 30 minutes of being
placed at the bottom of a marble-filled tube (0= bottom, 9 =top). Spacing
is at 2.5 cm intervals. Each fish was tested only once and only in one
treatment.
