Due to concerns that sea life was allowed to travel freely in and out of the port at Fukushima Daiichi after finding high levels of cesium in fish and shellfish caught in the port, TEPCO announced that it would put up a net in the end of January of this year to contain marine life. Ever since they initiated their monitoring and measuring of the marine life in the port, they have found rising levels of contamination, with no solutions at hand other than to keep catching the fish and exterminating them.
On January 30th, TEPCO workers captured multiple Murasoi fish from inside of the Fukushima Daiichi port which had been found to be contaminated with over 200,000 becquerels per kilogram of radioactive Cesium 134 and Cesium 137. On February 12th, workers captured a Greenling which was found to carry nearly 250,000 becquerels of Cesium. Three days later, on the 15th, they captured a spotbelly rockfish which measured 277,000 becquerels per kilogram.
This week TEPCO announced that on February 17th, they captured a Greenling fish which was found to contain 510,000 becquerels per kilogram of Cs-134 and Cs-137, twice the amount of the fish captured on February 12th. This is the highest levels of radiation ever detected in fish, and over 5,100 times the safety standards in Japan.
TEPCO has captured 5 other groups of over 60 fish, which it is still testing to measure the radiation levels.
