Bullhead - ProTip

Ed Carlson - professional fishing guide, ND, USA.
The Bullhead is a very close match for the look as well as the action of a foraging Madtom catfish. The larger pre-spawn female walleye find them irresistible, as do smaller male walleye. By slow trolling, or casting the Bullhead (SDR) parallel to the structure the walleye will likely be staging upon, you optimize your opportunity to connect with prowling pre-spawn trophy walleye.
