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 ad-
venture 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 to-
wards 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.
