Fukushima Diary reported the increasing amount of cesium in Pacific cod before.
(cf. [Sea contamination] Cesium in Pacific cod is increasing offshore Hokkaido)
Marine products contamination is spreading over Pacific ocean.
Japanese government is going to restrict the shipment of Pacific cod from Aomori prefecture as of 8/27/2012.
Aomori is the furthest North prefecture in Japanese main island. (380km from Fukushima)
Back in June, they measured 116 Bq/Kg of cesium from Pacific cod fished offshore Hachinohe.
Aomori prefecture requested the local fishery cooperation for selt-imposed control.
It was lifted at the end of July, but they measured 132.7 Bq/Kg of cesium on 8/9/2012 again.
They ended up restricting shipment of Pacific cod from Aomori for the first time since 311.
It is questionable why it is only Pacific cod.
