Is it true that a salmon will always return to its birthplace?

Yes, the salmon's life cycle is well-known. It is born in little streams far from the sea and spends the first few years of its existence in freshwater. It migrates down streams to rivers in the spring, sometimes journeying hundreds of kilometers, until it reaches the open ocean, where it spends the majority of its adult life. When it is time to deposit its eggs, the salmon returns to its birthplace to spawn and die. Salmon have oil-rich bodies that they gather up when swimming in the water. The oil provides the salmon with the energy it requires to make its way upriver.
