    The diagram represents the life-cycle of a certain breed of large fish known as the ‘Salmon’

    The life of a Salmon fish begins in the upper part of the river where the river is calm. the adult fish lay their eggs between the small stones present near the reeds. The eggs begin to hatch and the baby fishes come to life. These young fishes feed on reeds and spend about 5 to 6 months in this part of the river and grow up to 3 to 8 cm’s in length and are known as ‘fry’.

    The fishes then move to the lower region of the river where the currents move faster. They grow up to 12 to 15 cm’s length. At this stage they are known as ‘smolt’ and live here for about 4 years.

    After spending a part of their life in the river, they move in to the open sea. They Live here for 5 years and grow into adults. The average length of these adults are 70 to 76 cm’s . Once they reach their reproductive phase they go back to their birth place to lay eggs.
