The Niiyama Lures Mackerel (Opelu) Trolling Heads offer an ultra realistic representation of one of the most prevalent and sought after forage species for dolphin, marlin, tuna, and wahoo around the world. All Opelu lures are handpainted, showing amazing detail including scales, fins, gills, and a 3D eye. These trolling lures are designed to be double skirted giving you limitless color schemes and will result in a lifelike swimming action that closely mimics the escape of a mackerel away from its baitball by predatory pelagics. The Niiyama Mackerel Heads are handmade in Hawaii and available in 3 sizes, 5in, 7in, and 9in, enabling anglers to match the hatch to local mackerel and will ultimately help to land memorable catches out on the rip.
