Salmon undergo one of the most remarkable migrations of any animal. They transition from salt to fresh water, move against rapid currents and climb to high altitudes, travel hundreds of kilometers without eating, find the same stream in which they were born, reproduce and die.
- How do the migration patterns of different types of salmon vary throughout the year?
- How can scientists determine where a migrating fish is heading?
- What methods do scientists use to identify fish?
- How do scientists know if, how many, and where salmon disappear during their migration?
Let's investigate these questions in the lesson that follows >>
