The diagrams show the process through which a kind of fish called the salmon grows into an adult.
The lifecycle of the salmon has 3 main stages and takes place in 3 different locations.
The cycle begins when salmon eggs are laid among the reeds and the small stones of the upper river.
After around 5 to 6 months, these eggs turn into fry, which are 3-8 cm in length and begin to move to lower river where water flow is fast. Fry live there for 4 years and become smolt, measuring 12-15 cm in length, after which they migrate to open sea. They live in this new environment for approximately 5 years to become adult salmon (70-76 cm). The adult salmon then begins its journey back to slow- moving upper river where it lays eggs and the process starts over again.
