Fukushima fish in Ocean just as radiated now as during meltdown

Since most of these fish were not even born when the Fukushima meltdowns occurred it means that high levels of radiation must still be leaking into the ocean ongoing since the meltdowns occurred. This is very problematic for people trying to eat fish caught in the area. And further than that since many species of fish swim long distances during their migration patterns, (especially fish like Tuna, sharks and other predators), it becomes problematic for eaters of top of the food chain fish throughout the North western Pacific ocean generally.
