Willian Elliot from Eddie's Seafood Market in Edinburgh with a giant seven foot bluefin tuna weighing in at 150kg. June 14 2022 See SWNS story SWSCtuna. A fishmonger has taken delivery of this mammoth catch – a 7ft bluefin tuna tipping the scales at a whopping 150kg which is worth thousands. Campbell Mickel, 51, got the rare fish today (Tue) after buying it from traders in Barcelona on Friday - and said he was so excited he couldn't sleep. It arrived in the UK yesterday and was transported to Eddie’s Seafood Market, Edinburgh, overnight. It took four guys to haul the huge tuna onto the window display at the fish market - and Campbell said he will have to fillet it in on the floor as it doesn't fit on the counter. Campbell said he would not normally advocate eating bluefin tuna but said the 7ft fish was farmed rather than caught in the wild.
