Fishermen are back on the water along the coast of Fukushima after operations were suspended last month after large amounts of contaminated water from the crippled Dai-ichi nuclear power station were found leaking into the Pacific Ocean.
Kyodo news agency reported that 20 fishing vessels set sail Wednesday from a port in the city of Soma, 45 kilometers north of the beleaguered nuclear campus. The expedition is said to be a trial to check if radiation levels in seafood caught off Japan's northeastern coast are within the government's safety limits.
Similar trials have previously taken place in the past, but various interruptions have stalled the process.
Commercial fishing off the Fukushima coast was suspended for 15 months following the March 2011 earthquake and tsunami that caused the meltdown of three nuclear reactors. After trail fishing operations were restarted in June 2012, they were halted again last month, Kyodo reported.
