Tuna fishing tackle? leader size and lenght, sinker weights,hook size?
I’ve caught them on 12# to 80# line, #6 to #8/0 hooks, no weight to 8 ounces. Like the other responder said, it depends where you’re fishing, how you’re fishing (trolling or bait fishing or casting lures), which kind of tuna (albacore, skipjack, bluefin, yellowfin, bigeye, etc.), and how big the fish are (5 pounds on up to several hundred).
