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 figure illustrates the life cycle of

salmon

which is a kind of large fish step by step.

Overall

, we can see that

salmon

’s life cycle has three main stages, and starts with the upper

river

to the open sea. In the beginning,

salmon

eggs are put in the bottom of small stones among reeds in the upper

river

where the water is slowly moving.

This

phase has taken about 6 months. After that, baby

salmon

which are called fry, their length is 3 to 8 centimetres, are going to the lower part of the

river

where water has fast flowing, and they spent 4 years in that area.

Next,

after 4 years, the fries are becoming smolt, their length is 12 to 15 centimetres, go to the open sea, spend the rest of their 5 years in that and become adult

salmon

. The length of the adult

salmon

is between 70 to 76 centimetres. In the end, adult

salmon

go into the upper

river

for breeding and put their eggs on the small stones.
