The given diagram elucidates different phases in the life cycle of salmon along with the time spent in each phase, from hatching from the eggs to laying eggs.
Overall, this fish experiences three stages over roughly nine and a half years, in which it travels from the point of its origin to the seas and back, and passes through distinct stages and grows in size.
The life cycle of salmon starts when adult fish spawn in the slow moving waters of the upper river, under the reeds and in stones. These eggs hatch into small fish, fry, measuring between 3-8cm. It stays in these waters for 5 to 6 months. After this, as it grows bigger and attains the size between 12-15cm, at this stage it is termed as smolts, it moves to the lower river with slow moving waters and spends 4 years. Further, it moves into open seas for 5 years where it becomes an adult measuring 70-76cm. The adult fish swims back to upper river for spawning.
