The provided diagrams below represent the life cycle of species of large fish called the salmon.
Moving to the first step, upper river which slow moving with the salmon eggs below and small stones above the eggs as well as reeds on the top and need it to be for roughly 5 to 6 months. But then again in lower river flowing is quick which include fry fishes 3 to 8 cm and surviving for almost 4 years. But then again in second step smolt will extract which is 12 to 15 cm which are going into the open sea for approximately 5 years.
In third step, adult salmon which are 70 to 76 cm will extract from the open sea and coming back to the first step and start the recycling again. This is the life cycle of adult salmon which include three steps starting from upper river and motion into the lower river for the extraction of smolt and then adult salmon after almost 6 years.
Overall, the life cycle of species showed there is an almost 12 years for growing adult salmon from upper river to lower river and eventually to the open sea for 5 years.
