The diagrams below show the life cycle of a species of large fish called the salmon. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The image illustrates the category of fish species that are of substantial size namely the

salmon

.

It is clear that

the life cycle consists of three distinct stages, commencing from the downstream portion of the

river

and progressing towards the upstream section.

Firstly

, the fry, which has a 3-8 cm body size, lives in the lower

river

, which has a fast-flowing current, for approximately 4 years.

Subsequently

, when the body of the

salmon

grows up to 12-15 cm, called a smolt, it moves to the open sea for roughly 5 years.

Following

this

, the adult

salmon

migrates to the upper

river

. In

this

phase, it produces eggs and deposits them on the reeds with small stones, as

this

place is slow-moving. The eggs will stay and hatch after about 5-6 months. In the final stage, the newborn baby

salmon

will move back naturally to the first stage at the lower

river

, and the cycle will be repeated.
