Atlantic
salmon
spend
the
first
two
years
of
life
in
the
fresh
water
habitats
of
their
native
stream
(occasionally
three,
depending
upon
food
availability).
At
two
years
of
age,
the
fish
undergo
the
process
of
smoltification,
resulting
in
changes
in
certain
cells
of
the
gills
and
kidneys
(allowing
survival
in
either
fresh
or
salt
water),
and
brings
about
a
silvery
body
color
(better
camouflage
in
the
open
ocean).
Also
during
smoltification,
salmon
imprint
upon
the
chemical
"fingerprint"
of
their
home
river
which
allows
them
to
recognize
it
upon
their
return
from
the
sea.
Once
smoltification
is
complete,
and
water
temperature
increases
to
over
50o
F,
salmon
smolts
instinctively
migrate
downstream
to
the
North
Atlantic
Ocean,
and
eventually
to
the
cold
waters
off
Greenland.
Here
they
find
food
in
the
form
of
shrimp,
herring
and
capelin,
and
two
years
later,
at
four,
the
survivors
return
to
their
home
river
to
spawn.
Unlike
Pacific
salmon,
Atlantic
salmon
may
repeat
the
spawning
cycle
several
times.
