Salmon Use Earth’s Magnetic Field to Get Back to Their Home

Salmon Use Earth’s Magnetic Field to Get Back to Their Home

A recent EarthFix conversation followed between experts has revealed that salmon actually use Earth's magnetic field to get back to their homes.

As all know, salmon fish travels thousands of miles to the open ocean to feed and mature but experts were astonished to notice that when they return after a few years, they get back to the exact river where they hatched, to spawn their next generation.

Scientists couldn't understand how the fish actually succeeded in finding its way back, for which, they ran a new study that seems to have provided them with some good answers.

During the study, EarthFix's Ms. Ashley Ahearn when talked with Mr. Nathan Putman, a postdoctoral researcher at Oregon State University and lead author of the study (that appeared in Current Biology), it came to light that it is the magnets that work for the fish. Yes, it is none other than the earth's molten iron core (the thing that protects our planet from cosmic rays) that helps salmon and sailors to find their way home.

Mr. Putman explained that the earth's magnetic field can be predicted to get to your special location because they work as a proxy for geographic location, which is strongest at the poles, and starts becoming weaker towards the equator.

More perfectly one detects the strength of the magnetic field, easily the person can have an onboard system for assessing his latitudinal position and that is what the salmon are exactly doing.
