As bass get larger, food intake as a percentage of body weight decreases. This has been proven by researchers at the University of Southern Illinois who also observed during their study 90 percent of bass stomachs they examined contained only one food item.
Bass tend to eat 10 times their body weight per year, meaning that a 10-pound bass using these guidelines would only eat about five ounces a day. For argument’s sake let us reduce that by two ounces for a 10-pound lunker. All this fish would have to do is eat one sunfish per day and then remain dormant under the protection of heavy cover.
