Life cycle of a species of large fish called the salmon

The diagrams show different stages of the life cycle of

salmon

fish. Overall, It all starts with laying

eggs

in the upper

river

and by passing different stages they ended up in the sea as adult

salmon

. Looking into the details,

Salmon

fish lay

eggs

at the bottom of small reefs and stones. These

eggs

are laid in the upper

river

, where water flow is slow.

Eggs

are hatched in the upper

river

and small

fishes

from these

eggs

start growing. These

fishes

remained in slow water for the

next

5-6 months. After passing initial 5-6 months

then

these small

fishes

called fry with the size of 3-8 cm moved to lower rivers. In the lower

river

water flowed fast and

this

fry remained there for the

next

4 years. Once these

fishes

are grown into smolt and their sizes are approximately 12-15 cm

then

these smolt go to the open sea. In open seas, they spend their life which is around 5 years. The average size of adult

salmon

is about 70-76 cm. At the end of their life cycle, these

salmon

again go to the

river

and lay their

eggs

for the reproductivity of their species.
