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 are anadromous, meaning they hatch in freshwater, migrate to the ocean to grow, and then return to their birthplace to spawn. The distance asked is the full migratory loop from birth to spawning, which includes the journey downstream to the sea, years spent in the ocean, and the return upstream to the spawning streams. For sockeye populations, this overall travel distance is commonly around a thousand miles, making about 1,000 miles the best match among the options. While some populations might be a bit shorter or longer, 1,000 miles best captures the typical scale of their birth-to-spawning voyage.
