Scientists confirm Earth’s magnetism helps direct Salmon migration

It’s long been known that ocean salmon ready to return to the streams and creeks of their birth, must first find the region where their hometown stream is running. Once that’s determined, scientists say, the salmon can literally smell their way upstream to the spot where they originally emerged from creek gravels.

But when the salmon are well out to sea or off another coast, how did they find their way back to their “neighborhood?”

It’s been long suspected that the Earth’s magnetic field, that envelops the whole planet, has something to do with it. Scientists now say they have convincing evidence that each adult salmon, ready to spawn, becomes a needle on Mother Nature’s compass.
