2011年3月11日，日本东北地区发生了大地震（东日本大地震），并引发了巨大的海啸，造成许多渔船和渔港受损。地震和随后的海啸也对福岛第一核电站（FNPP）造成了严重破坏。因此，大量放射性铯（Cs）被释放到大气和海洋中，随后污染了福岛和邻近县的渔业产品。受FNPP事故影响，福岛县渔业合作协会联合会（福岛FCA）自2011年3月起自愿停止了福岛县近海的捕捞作业。海水中放射性铯的浓度随着海洋过程的发展而迅速降低，相应地，水产品中放射性铯的浓度也随之降低。2011年4月至6月，福岛外海的检查标本超过日本监管限值的比例为57. 1%，但在2015年4月之后有所下降并持续为0%。此外，福岛县的大部分渔业已经从地震及其后果的破坏中恢复。福岛FCA从2012年6月开始试捕作业。
On March 11, 2011, a massive earthquake and the resultant gigantic tsunami struck the Tohoku area of Japan (the Great East Japan Earthquake) and damaged many fishing boats and fishing ports. The earthquake and the subsequent tsunami also seriously caused the damage to Fukushima Daiichi Nuclear Power Plant (FNPP). Consequently, large amounts of radioactive cesium (Cs) were released into the atmosphere and ocean and subsequently polluted fishery products of Fukushima and adjacent prefectures. The Fukushima Prefectural Federation of Fisheries Cooperative Association (Fukushima FCA) has voluntarily stopped the fishing operations off Fukushima Prefecture since March 2011 due to the influence by the FNPP accident. The concentration of radioactive Cs in seawater rapidly decreased by ocean processes, and accordingly the concentration in fishery products did reduce. From April to June 2011, the proportion of inspected specimens off Fukushima exceeding the Japanese regulatory limit was 57.1%, but it decreased and continued to be 0% after April 2015. In addition, most of fishing industries in Fukushima Prefecture have been already restored from the damage by the earthquake and its aftermath. The Fukushima FCA started the trial fishing operation from June 2012.
