Facts about Pacific Salmon
- 08
After spawning and dying, Pacific salmon carcasses deliver marine-derived nutrients deep into forest ecosystems, fertilizing riparian vegetation and feeding dozens of wildlife species.
- 07
During their ocean phase, Pacific salmon grow dramatically, with some species increasing their body weight by up to 25 times their size at freshwater emigration.
- 06
Olfactory receptors allow Pacific salmon to detect their natal stream's unique chemical signature from up to 400 miles away in the open ocean.
- 05
Spawning Pacific salmon stop eating entirely once they enter freshwater rivers, relying solely on stored body reserves to complete their journey and reproduction before death.
- 04
Pink salmon have the shortest lifespan of any Pacific salmon species, living only two years before returning to freshwater to spawn and die.

Sockeye salmon undergo dramatic physical transformations during spawning, developing hooked jaws and changing from silver to deep red coloration within weeks of entering freshwater.
- 02
Coho salmon typically spend 18 months in the ocean before returning to freshwater streams to reproduce at ages three to four years old.
