Bluegill are feisty, fast-growing pan fish often found in large quantities in ponds and lakes. Large bluegill are often called bull gill or slab bluegill, and are ideal for fillets and fish fries. Unfortunately, it's not easy to catch bull gill, as they are often far outnumbered by smaller, faster bluegills that steal your bait. The solution is to use a large hook, such as a No. 6, which is too big for smaller bluegill to bite.
Tie the size 6 hook to your fishing line using a snell knot (see Resouces).
Bait the hook using bluegill bait, such as maggots, nightcrawlers, dough balls or insects. Slide the bait onto the length of the hook. This will reduce the fish's ability to tug the bait off the hook, and will also diminish reflections off the metal. Dip the baited hook into a liquid scent like garlic oil if desired.
Cast the line into the deeper part of a bluegill bedding area where the larger fish are likely present. Smaller bluegill will be located closer to the shoreline, and may pick your bait apart one bite at a time if their mouths are too small to fully bite a No. 6 hook.
Add a lead weight directly above the hook if the bait isn't heavy enough to sink the line. Slip the line into the hook, then press it shut using your fingers or teeth. Cast again and allow the line to rest for a few minutes. Agitate the line with your finger if nothing bites; the slight movement may draw a bluegill's attention.
Reel the bluegill in once hooked. Grasp the hook with pliers if it is inside the fish's mouth and lower it downward to free the tip, then rotate it out of the bluegill's mouth. Due to a No. 6 hook's large size it may be difficult to remove without damaging the fish's mouth .
