The draw below indicates the existence process of salmons.
Overall, there are three phases of salmons, which is from small to mature.
To commence with, the salmons are birthed, and they swim to a fast flowing river. It can be seen that this place is their home, and the approximate time they live here will be four years. Consequently, when the creatures grow up, a mass of salmons will leave their previous living place to go to the open sea. Then, the species consider the sea as their new accommodation. A half of a decade will be their time to live here. After that, when the salmons reach the mature from, they change their accommodation repeatedly. In the next period of 5-6 months, they choose the upper river with slow flowing and deliver eggs under stones which adjacent to stumps of reed plants. Finally, that organisms’ cycle life occur continously.
Turning to the specific phases of salmons, it is simple to see that the fry form possesses the measure of 3-8 cm. Next, there are smolt salmons have the length of 12-15 cm. The final ones are adult salmons which possess the length that is five times
more than that of the smolt phase.
