Sockeye Salmon’s Scarlet Run
Sockeye salmon put on the most colorful migration show in North America. Their bodies transform from silver to brilliant red as they leave the Pacific Ocean for their home rivers. Each fish carries a mental map of its birth stream’s unique chemical signature. They smell their way home through a maze of tributaries, some swimming over 1,000 miles inland to reach high mountain lakes. These determined fish burn through stored energy reserves like marathon runners.
