Late March is the time to venture off shore to the oil rigs for king mackerel in the 10- to 15-pound range. Fishing and chumming with live bait is one of the top ways to catch them. Trolling along oil rigs can be another successful method. For targeting specific areas, try Shimano Butterfly Jigs, which allow you to deliver the bait where you are most likely to find king mackerel. As a bonus, you may inadvertently pick up a few red snapper!
