The migration of salmon is an incredible journey, often covering hundreds of miles. Salmon use their keen sense of smell to navigate their way back to their natal rivers. They must overcome obstacles such as dams, waterfalls, and predators. The journey is often difficult and many salmon do not survive.
Once salmon reach their natal rivers, they spawn and die. The eggs hatch and the young salmon, called fry, spend several months in the river before migrating to the ocean. The cycle then repeats itself, with the young salmon returning to their natal rivers to spawn when they are mature.
