I heard some guys in Florida they were noodling for grouper. I think that would be awesome! go down there with some scuba gear and noodle up some grouper! I myself have went noodling several times on the Brazos River and particularly in Lake Whitney where there is a lot of rocks. I have never seen a big catfish down there personally I've got a lot of good size live bait but no big catfish I've had a few break the line but I didn't know if it was a diver or a gar or catfish or what. I always catch big catfish at Lake Tawakoni and Cedar Creek but never down that way I think that place is fished out.
You ever heard of moray eels?
I had a buddy who used to feed one almost daily, He went out one day during a windy day and was feeding it. He thinks the cloudy water got the eel confused, It bit him in the pinky area. They couldn't get the infection to settle down, eventually he had to have 2 fingers removed and a little part of his hand.
Now the best part, He did go back after he was healed and feed the eel again.
