salamon are born in fresh water, migrate to the ocean, then return to fresh water to reproduce. However, there are rare species that can only survive in fresh water habitats. folklore has it that the fish return to the exact spot where they were born to spawn; tracking studies have shown this to be true but the nature of how this memory works has long been debated.

Whenthe salmon die after spawning the river or crowded by these fish how does this effect the ecosystem?
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. - got this from someone else not me :)
