No, it doesn't. This is also FUD. Fukushima is a local environmental disaster - not a global one. It has done nothing to natural seawater radiation levels.
We are detecting a 'large' increase in radioactive Cesium in the world's oceans. It is, however, dwarfed by the amount of naturally radioactive potassium already dissolved in it. Radiation levels 500km from the disaster site have increased... By 2%.
