Results of the monitoring on radioactivity level in fisheries products

In accordance with the “Basic Policy for Inspections on Radioactive Materials in Fishery Products” and “Concepts of Inspection Planning and the Establishment and Cancellation of Items and Areas to which Restriction of Distribution and/or Consumption of Foods concerned Applies,” the Fisheries Agency, in cooperation with the relevant prefectural governments and organizations, has conducted sampling and inspections of fishery products at the major fishing ports in Fukushima and adjacent prefectures on a weekly basis to examine the possible contamination of fishery products by radioactive materials released from the Fukushima Daiichi Nuclear Plant of Tokyo Electric Power Company.

 In Fukushima prefecture, the suspension of fishery has been imposed on all the coastal and bottom fisheries (except trial fisheries targeting 27 species*).

* 27 species of which radioactive cesium concentration has been remarkably decreased were caught on a trial basis at the limited offshore area of Fukushima (20 km away from the FDNPS) and sold after inspection of each landing for each species. 27 species are the following: giant Pacific octopus,chestnut octopus ,Japanese flying squid,spear squid,swordtip squid,Japanese dwarf squid,horsehair crab,snow crab,whelks(Buccinum isaotakii,Neptunea constricta,Neptunea intersculpta and Beringius polynematicus),thornhead,greeneyes,rikuzen flounder,hilgendorf's aucord,willowy flounder,monkfish,flathead flounder,roughscale sole,rosy seabass,blackfin flounder,crimson sea bream,Japanese jack mackerel,Pacific barrelfish, Japanese sandlance (juvenile) and whitebait.
