The diagrams illustrate the process of how a big fish recognised as salmon life and breed. It is noticeable that there are three steps of salmon's growth from fry to adult.
To begin, salmon put their eggs in the upper river which has slow moving currents and in the opposite between reeds and small stones. This is the appropriate place to protect their eggs from predators, and the eggs will be incubated around 5-6 months. After incubating process, the eggs will change to be a fry which has body's size approximately 3-8 cm. Following this, the fish will adapt in lower rivers which is fast slowing currents in which they will stay at the location for 4 years.
Next, the fish are metamorphosed to be smolt that has 12-15 cm body's long. They will be breed in the open ocean for 5 years, and it will continue until they become grow to be adult salmon. Adult Salmon has a large body about 70-76 cm which can be consumed for society as food chains.
