The diagram illustrates the growth of salmon fish in three stages called fry, smolt and adult salmon.
At first, we can see that adult salmon lay eggs in the upper river with small stones. After that, they move to reeds and stay there for approximately a five- to six-month period and turn into fry. Followed by, the fry move on to the lower part of the river and last there around a four years long time. At the end of the period, the fry turns into smalt with 12 to 15 centimeters.
In the last stage, it is evident to us that the smolts now swim to the open sea and remain there for five years and grow between 70 and 76 centimeters in this period.
To sum up, now we can conclude by saying that the process diagram depicts the life cycle of huge salmon fish in three distinct stages.
