How do migrating salmon return to the place where they were hatched?

Salmon migrate from freshwater streams and rivers to the sea. They return to their birthplace to reproduce. It is believed that the position of the sun and the stars as well as the differences in the earth’s magnetic fields help them find their way. Differences in the temperature and chemical properties of the water as well as the salmon’s sense of smell also play a role.
