I used to use baby bullfrogs for bait for leery lmb. They just could not resist them. And nothing better than a surface explosion of a big lmb going for a frog. But it's the polliwogs they eat all day long. Nothing fatter and slower in the pond. But they make terrible bait, too fragile to cast. Many of my lures are polliwog color patterns and size. They outfish everything else in my tackle box.
