H HOW DO SALMON

FIND THEIR WAY?

You are mistaken if you think that migration is peculiar to birds.
In fact, there are many migratory species on land and in sea. In

this section, the adventure of salmon, a migratory fish species,
will be examined.

Salmon are born into the world as they hatch from eggs the

females of the species lay in the river. They grow and hunt in this
place for several weeks after which they start to advance down

the river. During this journey towards the sea, they encounter
dams and polluted water, and try to avoid dangers

such as bigger hunting fish. Having overcome all
these and reached the sea, they spend several

years there. Once they mature
enough to spawn, they swim back

to the fresh water.
