I think that's largely because tuna fishing is a crapshoot, whereas there are specific things you can do to up the ante on finding record-size sharks, bass, and trout. When you fish for tuna, the first five might weigh 30 pounds. Then suddenly you've got a 200-pounder on. I've actually heard that the yellowfin record had been broken once or twice, but considering the anglers didn't know what they hooked, they rested the rod on the rail, had people on the boat touch the line, and did other things that disqualify the catch from IGFA status. Luckily for Livingston, the Vagabond crew had a good idea what caliber of fish they were dealing with. I think it's safe to say this record may never be broken again. So congrats, Mr. Livingston, and enjoy the sashimi. Check out the full story here.
