BAIT FISH
The
importance
of
bait fish to successful
fishing
can't be over-
emphasized. 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. Bait fish can also be the
young
of
game fish,
such as
crappies,
bluegill,
and bass.
Most bait fish are concentrated 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 Z-5000 to find the bait fish
first. A school
of bait fish will look like a "cloud" on the
Z-5000's
display.
Usually, game
fish will be
nearby,
often
directly
beneath the school of bait
fish.
