You need a pole, a reel, and some line, lol.
I caught a 12lb Brood on 4lb Flouroclear which has a low diameter compared to most lines, I have also caught 2 others about 6-8lbs. It is just a matter of how well your knot holds up and how you play the fish, you could probably catch them on 2lb if you were really hardcore.
1/8oz slide sinker--Swivel------leader varies by pond depth----size 16 treble.
Fish a slack line when you can, and try to set the hook before the fish feels the resistance, they will sometimes drop it when they feel tension. I would never go higher than 6lb Maxima for leader.
