How do salmon know where their home is when they return from the ocean?

Scientists believe that salmon navigate by using the earth’s magnetic field like a compass. When they find the river they came from, they start using smell to find their way back to their home stream. They build their 'smell memory-bank' when they start migrating to the ocean as young fish.
