Killian's favorite tactic for catching bull sharks involves using a live ladyfish on a modified free-line rig.

"I'll put on a 1-ounce weight and then lower the ladyfish on a steel leader with a circle hook only about halfway down the water column.

The bulls feed around that area and down low a lot, and they can't resist a ladyfish. And when one hits, the fight is on.

"They don't put up a fancy fight, but they will just plain beat you up," he said. "And that's what I like about them."
