Title: The Life of a Salmon


1
The Life of a Salmon
  • By Sean Ruckman

2
The Beginning
  • Salmon eggs are commonly laid in streams
    that are from 10 to 700 miles away from the
    ocean. These eggs are laid in the fall and
    incubate over the winter.

3
The Fry
  • After the salmon eggs hatch, they begin
    to mature into fry. They then begin to develop
    vertical bars called parr marks. These marks help
    to keep the young salmon camouflaged from
    predators.

4
Becoming a Smolt
  • As the fry begin to grow, they start to
    migrate downstream towards the ocean. On their
    way, they experience many changes that some might
    call puberty. They start to change color into a
    silvery color and are able to breathe in salt
    water. These changes are crucial to their
    survival.

5
It Begins Again
  • The salmon has finally became an adult.
    When it is time to lay the eggs, the salmon will
    swim back to the stream where they were born and
    lay the eggs there. After the eggs are laid, the
    salmon will swim back to the ocean and the new
    born salmons will go through the same amazing
    process.
