Magnetic map in nonanadromous Atlantic salmon

Creator:

Scanlan, Michelle M., Putman, Nathan F., Pollock, Amanda M., and Noakes, David L.

Abstract:

Long-distance migrants, including Pacific salmon (Oncorhynchus spp), can use geomagnetic information to navigate. We tested the hypothesis that a “magnetic map” (i.e., an ability to extract positional information from Earth’s magnetic field) also exists in a population of salmon that do not undertake oceanic migrations. This study examined juvenile Atlantic...

Geomagnetic field influences upward movement of young Chinook salmon emerging from nests

Creator:

Putman, Nathan F., Scanlan, Michelle M., Pollock, Amanda M., O'Neil, Joseph P., Couture, Ryan B., Stoner, Joseph S., Quinn, Thomas P., Lohmann, Kenneth J., and Noakes, David L.

Abstract:

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...
