Oil rigs are havens for targeting a wide range of pelagic species, but did you know that summer is the ideal time to catch yellow-fin tuna on top of the water? Oil rigs create structure for fish and habitat for baitfish, which are hunted by yellow-fin tuna, pushing their prey towards the surface of the water column. To locate tuna prey, keep your eyes open for flocks of birds and for fish blowing up on bait at the surface. Once you’ve found them, duplicate conditions with the Shimano Orca, a heavy-duty topwater bait with a bubble chamber that produces a splashing system that replicates the frenzy action of evading baitfish. Give the Orca system a try on your next excursion to the oil rigs!
