The diagram below shows the life cycle of a species of large fish called the salmon. Summarize the information by selecting and reporting the main features and make comparisons where relevant.
The diagrams illustrate the life cycle of a
salmon
fish, highlighting three main stages: fry, smolt, and adult salmon
.
Initially
, salmon
eggs hatch in the upper river
, a slow-moving water body with reeds and small stones. This
stage lasts approximately 5-6 months, in which newly hatched fish, termed "fry", measure between 3-8 cm in length.
Subsequently
, the fry migrate to the lower river
, characterized by faster-flowing water, where they continue to grow for about 4 years. During this
period, they transition into the "smolt" stage, reaching a length of 12-15 cm. The smolts then
travel towards the open sea.
In the open sea, the salmon
spend roughly 5 years maturing into adults, growing to a length of 70-76 cm. Once they reach full maturity, the adult salmon
migrate back to the upper river
to spawn, thereby completing their life cycle.
In summary, the salmon
's life cycle encompasses significant growth and development in various aquatic environments, from the upper river
to the lower river
and finally
the open sea, before returning to their birthplace to reproduce.Submitted by Nastaran_zandy on
