The record for the largest yellow fin tuna catch is currently held for a 405-lb tuna and a catch of 427-lb was denied the recognition for the largest tuna catch by the International Game Fish Association because of a technicality as reported in Foxnews dated 18th April 2012.
Robert Pedigo had caught the 427.9-lb yellow fin tuna off the coast of Puerto Vallarta in Mexico. It was a tough tussle between man and fish and man won – but, because a deckhand had accidentally touched the fishing rod, Robert could not claim the record.
One Danny Osuna, a local captain was on that day a deckhand in the fishing trawler ‘Journeyman’.
The rule book stipulates that in case the angler feels that a history is in the making, he must ensure that no one else helps him in any way, not even by touching the fishing rod.
Hence, the existing all-tackle record for the largest yellow fin tuna catch remains at 405-lbs and its credit goes to Mike Livingstone of Baja Sur, Mexico – he had created history on 6th December 2010.
