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

The diagram illustrates the salmon’s life cycle in 3 different areas, including with

river

, estuary and ocean. It can be seen that there are many stages of the differentiation of

salmons

from eggs to mature adults.

Moreover

, we can

also

see that

salmons

spend most of their time of their lives in a

river

and

ocean

Fix the agreement mistake

oceans

show examples

. It will pass an estuary only once in their lifetime.

To begin

with, their incubation and transformation period, after mature

salmons

lay eggs which are transformed into small young

salmons

in a

river

. The young

salmons

stay in the freshwater for a

while

to grow up completely.

Then

, the fish swim through an estuary one time in the adolescent stage to an ocean where it can migrate to many places.

However

, in the mature stage,

salmons

will swim back upstream to the spawning area and lay eggs in a

river

.

Then

, the life cycle reoccurs.
