Wow that's crazy. I wonder when a bass eats something that large how long before they get hungry again?
Not sure if it means anything but a lot of the trophy fish I mount as a taxidermist have empty stomachs. The theory is really big fish eat a large food item(s) and don't eat again until the food is digested. That may be part of the reason they are difficult to catch as they are off feed a good part of the time.
