I've never done it in large numbers but feeding training LMB in an aquarium isn't difficult. Even larger LMB can be trained. LMB relate you as food when you start dumping minnows, shrimp, crayfish etc into the tank. After a while, they'll nail just about anything you put into the tank... So at first I start with tasty items like like minnows or shrimp. Then switch to dead minnows or shrimp. Then freeze dried shrimp. And then eventually pellets... It generally takes a couple months for the progression to happen.
