you
can make

lake. Unless

BAIT FISH
The
importance
of bait fish to successful
fishing
can't be
over-empha-
sized.
They
are the
principal
food of all
game
fish in most
waters.
Bait fish are the
plankton
feeding forage
fish,
such as
minnows and
shad. Bait fish 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 unit to find the
bait fish first. A school of bait
fish
will look like a 'cloud" on the unit's
display. Usually, game
fish
will
be
nearby,
often
directly
beneath the school
of bait fish.
