The following diagram illustrates the complete life cycle of a salmon. It’s whole life cycle lasts for up to 8 years. Here, it can be seen that the life cycle of a salmon has 7 prominent stages until it fully develops into a spawning adult and dies.
The life cycle commences when the mature adult salmon deposits eggs in the fresh water. These eggs hatch in around three months. The next stage is called as alevin in which the juvenile fish still feeds off the yolk inside it for several weeks. Then comes the fry stage where the fish develops ability to swim on its own when it is around 5-10 weeks old.
In the fourth stage of the life cycle, known as Parr, when the fish is a few months old, the mature stage starts kicking off and finger markings on the body are noticeable. Stage five is the Smolt stage, fish is a good 1 to 3 years old and embarks on the journey of heading out to the sea solitarily. After which, it turns to an adult and have already spent around 8 years in the sea. It, furthermore, turns into a spawning adult who is ready to lay eggs in the fresh water again. After spawning, the adult salmon dies within a two-week span.
