Resource: One fish, two fish, dead fish, new fish
Media (6 mins): We're following the underwater trail of hundreds of thousands of salmon returning to the stream where they were born. Excerpt: "Salmon are really amazing because they have this complex life cycle that includes the land, the sea and then back to the land. They hatch in streams, sometimes hundreds of kilometres inland. And then they start migrating down the river into estuaries where the river meets the sea."
