The wreck of submarine U-864, located at around 150 m depth west of the island of Fedje, had large quantities of mercury on board when it was sunk in 1945, and the surrounding seafloor is heavily polluted with metallic mercury. The Institute of Marine Research annually monitors, on behalf of the Norwegian Coastal Administration, the content of mercury in seafood caught around the wreck as well as reference localities four nautical miles north and south of the wreck. In 2019 we analysed fillet of 65 tusk (Brosme brosme) and claw meat and brown meat/hepatopancreas of 58 edible crab (Cancer pagurus) for total mercury. Seven tusk had mercury levels above the maximum level set for food safety in EU and Norway, but the level was not elevated at the wreck site relative to the coast of western Norway or the reference localities. Claw meat of crabs had a mercury level well within the maximum levels set for food safety, and there was no difference between the three localities. Mercury in viscera showed the highest levels in crabs caught at the wreck site, and both at the wreck site and at the northern site the levels were higher than at the site four nautical miles south of the wreck. Average mercury levels in crabs caught near the wreck of U-864 were relatively high in 2019 compared with earlier years, but the level was lower than in 2018 and the variation between individual crabs was large.
