TEPCO announced that it had captured a Murasoi fish from inside of the harbor at the crippled Fukushima Daiichi nuclear power plant. Analysis detected 254,000 becquerels per kilogram of radioactive cesium in the fish, 2,540 times the legal dose. The internal dose if eaten would be 4mSv per kilogram.
The Murasoi fish is somewhat similar to the rockfish, which have also been found to be severely contaminated in the waters around Fukushima Daiichi.
According to TEPCO, the fish was captured near the port on the east side where high levels of contamination have been detected. There are no current restrictions which prevent fish from coming and going freely in and out of the port, but TEPCO will make plans to install nets in the harbor mouth and outside the harbor in response to the latest findings.
