A fish was caught on Friday midway between Fukushima and Tokyo that contained dangerously high levels of radioactive iodine and high levels of cesium.

This catch has prompted Japan to announce its first legal limits for radiation in fish, according to the AP. Previously Japan had said it was enough to ban fishing in the near proximity of the nuclear plant.

Japan also just announced a huge surge in ocean contamination, as radioactive iodine-131 at 7.5 million times the legal limit was found near the plant, according to Japan Times. Yesterday, levels were only 5 million times the legal limit.

Ocean contamination will probably get worse. Yesterday TEPCO commenced a plan to dump 11,500 tons of radioactive water into the ocean, and it said a leak of even more toxic water could last for months.

Japan, like the Gulf of Mexico during the oil spill, faces a serious economic blow if its fishing industry dries up.
