Try a limb-line attached to a circle-hook baited with a mouth-sized brussel sprout.
Suspend the baited hook at or slightly below the water's surface. Secure the terminal end of the line securely to the flexible end of the limb, but lightly twist-tie several feet of free line in loops to the limb so the fish can easily pull the loops free once it takes the bait.
IF all works well, the fish will take the bait "deep" to chew on it while moving away from the limb. As the line become taught, the circle hook will engage mr. leathery-lips and hold fast (they rarely come free on their own). The flexing limb allows some "give", unlike a solid anchor-point.

One more key tip: Tie the circle hook to the line using a snell knot, with the line passing through the eye from the side facing the hook-point. This method of hook-attachment better insures that the point will properly rotate and enter flesh as the eye exits the fish's mouth.
