How to Rig for Blackfin Tuna

Thunnus atlanticus

Blackfin are a smaller tuna found off Florida, the Gulf, and the southeastern US, often schooling around offshore humps, wrecks, and behind shrimp boats. They have sharp eyesight, so use fluorocarbon leaders and small hooks with live bait in a chum slick, or vertical jigs worked fast. They are one of the most accessible tuna for small-boat anglers.
