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.

Baitfish arethe

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.
