The diagram below shows the life cycle of a salmon, from eggs to adult fish.

The diagram illustrates the different stages of reproduction of a salmon in the river

as well as

the ocean and its growth in various water bodies.

Overall

, there are 3 unique places where the fish grow.

Although

the growth occurs in all 3 regions, in freshwater, the backwater and the sea,

however

, the birth of these fishes takes place in the river and they become mature in the ocean.

Firstly

, in the river, the adult salmon spawns the eggs which are

then

incubated.

After

this

, the eggs hatch and small hatchlings emerge out of them. These hatchlings are reared in the freshwater for some time before they can move into the estuary for

further

rearing.

Furthermore

, the slightly grown salmon migrate to the ocean where they attain maturation in the seawater.

Finally

, the fishes return back to the spawning areas in the freshwater for reproduction, laying eggs there. The cycle repeats all over again.
