The process depicts how salmon grows and reproduces eggs.
Overall, the procedure contains five stages, starting from salmon eggs in upper river, and finishing with adulthood.
It is presented that initially, salmon eggs are surrounded by reeds and small stones, while being in an upper river, owing to the fact that it is slow-moving. After spending 5-6 months there, they turn into fries that are at least 3cm, and can grow up to 8cm. It is shown that afterwards, they move to a lower river, which is fast-mowing. As it is noted, fries live there for around 4 years.
Before coming to an open sea, they get bigger in size, being estimated at 12-15cm. As represented in the procedure, so-called smolts spend around 5 years there prior to becoming adult salmons, which are 20-26cm.
