Bigeye are the fish that make canyon crews set the alarm for the pre-dawn troll. Built for deeper, cooler water than yellowfin, they feed hardest in the low light of dawn and dusk, and a good bigeye is a serious, drag-melting adversary. They are less predictable than yellowfin but a genuine prize when they show.
How to identify them
As the name says, bigeye have a noticeably large eye, an adaptation for feeding deep in low light. They are stocky and deep-bodied, similar to a yellowfin but with shorter, more uniform finlets and pectoral fins and a slightly different body profile. Telling a bigeye from a yellowfin at the boat can take a practiced eye.
Where and when
Bigeye hold along the deep canyon edges and drop-offs and are caught on the same offshore trips as yellowfin, summer into fall. The defining feature is timing: the bite windows are dawn and dusk, and often into the night. Crews fishing the canyons for bigeye plan around those low-light windows.
Tip Fish the edges of the day. If bigeye are around, the troll often comes alive in the last of the dark before sunrise and again as the light fades, so have the spread out and dialed in before first light.
How to catch them
Bigeye are primarily a trolling target in our waters, often on lures and baits run a bit deeper than a standard yellowfin spread, using weighted lures or planers to get down to where the fish are feeding. When a bigeye eats, the reel screams, hang on and let a big fish be a big fish before you try to turn it.
Eating
Bigeye is prized sashimi tuna, rich, deep red and often higher in fat than yellowfin. Handle and ice it properly offshore and it is some of the best eating in the ocean.
