Big LMB are pretty darn good at eating their own. 6 acres is a lot of work, but you really have to do the work yourself. Fishing, trapping, electroshocking can all be utilized... Relying on other species of fish is iffy. They will eat what they want to eat, not what you want them to eat. It's the same for pike, musky, blue cats or flatheads or any other high end predator... In studies I have seen on flathead catfish diets, I rarely see LMB being high in their stomach contents. Sunfish species, bullheads and shad are high on the list.
