CD 14 — with 30-pound fluorocarbon leader is a favorite of those who can’t procure enough live pilchards for chum. When pulling a pair of swimming plugs, incidentally, position them roughly 100 and 150 yards back and bring your speed to around 10 mph. Towing the lures far back and fast catches more fish. Flutter jigs also put fish in the box. First, mark the tuna on the fish finder; then lower the irons. Again, 30-pound fluorocarbon leader is best, as is rapid and radical jigging. The third approach, more effective for targeting larger blackfins, is broadcasting dozens of live pilchards behind the boat, along with a couple of hooked baits. When the positioning and timing of the baitfish dispersal are right, the tuna rise in a frenzy.
