Salmon seem to remember where they were hatched and will attempt to return to the spot. The unusual thing about this is, sometimes it involves swimming,upstream or against the current.
They spawn.
A young salmon (or a trout of the salmon family) is called smolt.

Salmon encounter much hardships on their journey to spawn. A salmon has to swim the opposite way a stream is flowing, Salmon have to jump up mini waterfalls where hungry brown or black bears are waiting, other fish tend to eat the eggs or the fish that are about to spawn, they risk getting eaten by birds such as gannets and hawks and humans tend to prey on Salmon to eat.
The 'unusual' factors are - the way the fish return to the river where they hatched in order to mate and spawn - and the fact that, due to the vast amount of energy it took to reach their spawning ground, once they've mated the adults die !
It depends on the species of the salmon, Chinook (King) Salmon spawn between the months of September and October. Coho (Silver) Salmon spawn between the months of October and November. And Atlantic Salmon spawn between the months of November and December.
Salmon is one fish that travels up a river to spawn.
Salmon live in the ocean, but swim up rivers to spawn.
A group of salmon is called a run when they swim together up a river to spawn.
because Salmon are swimming upstream to spawn and the bear knows....they can sense them.
Salmon are born in fresh water, migrate to the ocean and then return to the fresh water to spawn. Salmon have the reputation of returning to the same place they were born in order to spawn.
Recruit - able to spawn (produce young).
