After spawning salmon deteriorate rapidly as their bodies have lost a lot of corticosteroids during spawning.This is called programmed aging. Most adult salmon die in the streams they were born in.
Salmon die after spawning due to exhaustion and malnutrition. As most salmon are sea fish, the environment of the creeks and streams are poisonous to them and they are unable to feed as they swim up stream. By the time they get to the spawning grounds they have used up their stores of energy and cannot get back to the sea.
