BAIT FISH
The
importance
of baitfish to successful
fishing
can't be
overemphasized.
They
are the
principle
food of all
game
fish in most
waters.
Bait fish are the
plankton feeding forage
fish,
such as minnows and shad.
They
can also be the
young
of
game fish,
such
as
crappies, bluegill,
and
bass.
Most bait fish concentrate within
five feet of the surface where
sunlight
promotes
the
growth
of the
plankton
on which
they
feed. One method of
fishing
is to use the X-55Ato find the bait fish first. With the Fish ID feature
off,
a school of bait
fish will look like a "cloud" on the
display. Usually, game
fish
will be
nearby,
often
directly
beneath the school of bait fish.
