From birth to spawning, how far can a sockeye salmon travel?

• A. 800 miles
• B. 1,500 miles
• C. 1,000 miles
• D. 500 miles

Answer: (C)

Sockeye salmon undertake a long, two‑phase migration: they hatch in a freshwater stream, move to the ocean to grow and feed, and then swim back upstream to their birth stream to spawn. The total distance from birth to spawning is typically about 1,000 miles for many populations, reflecting the substantial ocean wandering plus the river return. Distances can vary—some populations travel shorter distances, others longer—but 1,000 miles best represents the common magnitude of this journey. Their return to the natal stream is guided by strong olfactory cues, helping them navigate home to spawn.
