The details on the metamorphosis of one of the species of huge fish family: Salmon has been demonstrated by the given process diagram.
Looking from an overall perspective, it has been vividly analyzed that there are altogether 3 distinct steps where production of the egg under the reeds and stone is the first and development of adult approximately five years is the final one.
Turning to the more details, the hatching of the egg takes place inside the water and the fry fishes are lived for about five to six months in the slow moving upper river after that the move to the lower stream which is must faster than the previous one. They spend almost four years and become young fish which is 12-15 centimeter long.
Moreover, these fishes now migrate into the open sea through the river and transform to adult fish which is approximately 5 years of age. Then the adult fish becomes 70 -76 centimeter in size. It again move to river and is capable of laying egg. In this process the immature fish go through various stages and finally becomes mature one and the lifecycle continues again.
