can't
be over-
emphasized. They

principle

planktonfeeding
foragefish,
suchas 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 usetheX-40 to find the baitfish
first. A school of bait
fish will look like a
"cloud" on theX-40's
display.
Usually, gamefish
will be
nearby,
often
directly
beneath the school of bait
fish.
