The 20ft conger eel weighed 131lb (59.5kg) after it was gutted and was caught off Plymouth in Devon.
Fisherman caught it by mistake after it became tangled in their trawler's nets.
They later posted an image of the beast on Facebook with the caption: "Conger 130lb gutted landed in Plymouth market this morning! What a Beast."
Fisherman Vic Evans held the previous world record for a Conger Eeel, which he caught six miles off Brixham in Devon in 1995.
It weighed 133lbs 4oz before it was gutted. But the new pretender is believed to have weighed about 155lbs to 160lbs before it was disemboweled.
The conger eel landed at Plymouth Fisheries was caught by the inshore trawler 'Hope'.
The conger sold for just £40 at auction, equivalent to 70p per kilo.
