the process of life expectancy in salmon

The flow chart depicts the development of salmon from eggs during its life expectancy. Overall, It is clear that there are three distinct stages illustrated in the process, commencing with producing eggs in the freshwater environment and ultimate with the growth of mature salmon in saltwater. The initial step is when female salmon lay eggs in the slow-moving upper reaches of the river where hidden among reeds and small stones, after five to six months the eggs hatch into fry. For approximately the next four years, those baby salmon will reside in the lower, fast-flowing in their river. At the same time, they are measured from three centimeters to eight centimeters in terms of length. By this step, salmon reach twelve to fifteen centimeters they are called smolt, during this period they migrate into the open sea. Eventually, it accounted for five years to salmon have grown to an adult size which is between seventy and seventy-six centimeters. The final step of the cycle is when adult salmon mate in order to lay eggs. Having complete all these steps, all salmon's natural life will then begin again.
