Feed trained bass are mostly northern LMB. If you can find someone with feed trained florida LMB I'd imagine they would grow as big as non feed trained Florida LMB.

We believe feed trained bass die younger because they grow quicker than non feed trained bass. That's all I remember without doing additional research.

You only get feed trained bass by crowding them in small tanks and feeding them pellets while they are fingerlings. Eating pellets is unnatural to the them. In ponds the bass aren't confined to one small area so most of the time they don't learn to eat pellets.
