eyeballs can be caught the same way you catch any other tuna, except there are just not as many of them. You see most of them caught on the troll in packs of anywhere from 1 to ive seen as many as 10 in a pattern. Lots of people think big heavy dark lures work best, hex heads, jets, big squids. Lots of peopel jig for them right before dawn in the canyons around 4-5am jigging deep to about 250-300. Ive seen them caught on bait as well. Its just that longfin and yellowfin outnumber the big eye by so many its hard to target them specifically and be successful.
