Study confirms link between salmon migration, magnetic field

A team of scientists last year presented evidence of a correlation between the migration patterns of ocean salmon and the Earth’s magnetic field, suggesting it may help explain how the fish can navigate across thousands of miles of water to find their river of origin.

Recently, scientists confirmed the connection between salmon and the magnetic field following a series of experiments at the Oregon Hatchery Research Center in the Alsea River basin. Researchers exposed hundreds of juvenile chinook salmon to different magnetic fields that exist at the latitudinal extremes of their oceanic range. Fish responded to these “simulated magnetic displacements” by swimming in the direction that would bring that toward the center of their marine feeding grounds.
