The visual stimulus demonstrates the various stages of the life of a greatly sized fish breed known as salmon. Overall, the life cycle of this aquatic creature is categorized into three stages based on age, size, and place of presence.
Firstly, when juvenile fish, referred to as fry, hatch they are transferred to lower areas of the river where water flows at a rapid rate. The premature beings remain in this region for roughly 4 years to grow in size. When adolescence is reached, the fish are typically between 12 to 15 centimeters in lengths. During this period, smolts move to open sea and inhabit these areas for approximately 5 years. Finally, when the fish become mature and sexually active, they migrate to upper river areas with slow-paced water to spawn, specifically amongst the reeds and gravel. Their residence here usually takes up to 6 months. Thereafter, the process is repeated in a cyclical manner for each new generation.
To put it concisely, the life of salmon follows a recurring trend and consists of three majors steps of maturation. This ongoing development pathway gives rise to the continuation of survival for this species.
