▶ Your Answer :
According to this diagram, the information about
the life cycle of salmon is given. Each step of salmon’s growing and change in
its living area are described.
Firstly, the salmon leaves its eggs between
small stones, which locate below reed in the upper river. Salmon eggs spend approximately
5 to 6 months in this slow-moving, upper part of river. After that, the baby
salmon of 3 to 8 centimeter, which is called ‘fry’, moves its habitat to much
lower river where flows are running faster. The fry usually spends 4 years here
and grows into ‘smolt’ with the size of 12 to 15 centimeter.
For the next step, this middle-aged smolt
alters its living area one more time to the open sea, which seems quite a
different environment. When 5 years are passed, now the adult salmon, whose
length of body is about 70 to 76 centimeter, returns to the upper river where
it is born.
In conclusion, it takes almost 10 years for
the salmon to grow up and to come back to its hometown. The salmon also spends
a half of its life in the open sea to be the adult.
