Atlantic salmon uses Earth’s magnetic field for navigation - science news

Similar to their relatives, the Pacific salmon, the Atlantic salmon uses Earth’s magnetic field as a navigational tool, according to a new study.

Interestingly, the study showed that the fish do not lose the ability to use the magnetic field as a GPS through several generations, even after they have been transplanted into a land-locked lake.

The use of the magnetic field explains, in part, how salmon can find the way to their river of origin. This ability does not seem to be lost when not used, as in the case of the fish confined to a small space.
