Observations

Like in many other salmonid species, most animals die after spawning [0524]. While most animals return to spawn in rivers, however, there are alternative life histories: parr and jacks have a small body size and mature early, yet while jacks return early to spawn from the ocean, parr do not migrate and can survive reproduction and breed again [0413]. Unverified estimates suggest these animals may live up to 14 years [0454].

Interestingly, one study showed that animals infected with a Pearl mussel parasite live longer, have a lower cancer incidence, and avoid the typical "programmed death" that follows reproduction possibly because the parasite needs the salmon to live one more year to complete its life cycle [0414].
