The given diagram illustrates the process of the development of a creature of large fish called salmon.
Overall, it is evident that the whole life cycle provided three main stages, starting with the salmon eggs in the upper river. This process took about a long-year period for about 10 years.
At the beginning of the salmon’s life, it was salmon eggs, hided under the small stones and reeds, living in the upper river with a slow-moving. This time needed around 5-6 months after its growth. After being hatch, it became a kind of 3-8 centimeters fish called fry, moving to the lower river with a fast-flowing for almost 4 years before getting bigger.
At the next stage of the life cycle, it has been grown to a kind of fish with 12-15 centimeters length, called smolt. Migrating to the open sea after 5 years, smolt completely grew to mature individuals, as well as salmon. As a life circle, salmon came back to its birth place and continued to born new species.
