First credit for photo from Seeker FB page. I haven't caught any "big " tuna and always wonder how 4/0 5/0 hooks, recommended for small bait, could work. I don't have any info for scale of this photo but it is definitely small hook big tuna. This one just looks like luck, or is this typical of what is wished for? Big ol' Mustad 16/0 circles thru the jaw, now I see this as common but haven't seen the above or even close.
