Bluegill are one of the best baits for largemouth bass.  In ponds, this may be one of the easiest ways to target quality bass on a consistent basis.  The key is to not go too big when fishing with bluegill as bait.  Try to stay with bluegill in the 3 to 4 inch range if you’re looking for action and some quality fish.  As you go bigger, you will usually get less bites, however, those bites may be real nice bass.
