According to ASR Ltd (the folks who created the oceanographic model shown in the video):
"We use a Lagrangian particles dispersal method to track where free floating material (fish larvae, algae, phytoplankton, zooplankton...) present in the sea water near the damaged Fukushima Daiichi nuclear power station plant could have gone since the earthquake on March 11th. THIS IS NOT A REPRESENTATION OF THE RADIOACTIVE PLUME CONCENTRATION. Since we do not know exactly how much contaminated water and at what concentration was released into the ocean, it is impossible to estimate the extent and dilution of the plume."

And, The Woods Hole Oceanographic Institute basically found that, even off the coast of Japan, the samples they took (last year) were for the most part not hazardous to human health:
"....analysis of samples from the study site show that the amount of radiation in the ocean fell well below EPA standards that would deem it unsafe to use as drinking water. 'We knew that the radionuclides had to be moving off shore very rapidly once they entered the water,' said Buesseler. 'Once they did, they quickly dispersed across a wide area and began mixing into the deeper layers of the ocean.'"
"'The radioactivity of the fish we caught and analyzed would not pose problems for human consumption,' said Fisher. 'It does not mean all marine organisms caught in the region are perfectly safe to eat. That's still an open question.'"
