No detectable amount of tritium has been found in fish samples taken from waters near the crippled Fukushima No. 1 nuclear plant, where the discharge of treated radioactive water into the sea began a month ago, the government said Monday.

Tritium was not detected in the latest sample of two olive flounders caught Sunday, the Fisheries Agency said on its website. The agency has provided almost daily updates since the start of the water release, in a bid to dispel harmful rumors both domestically and internationally about its environmental impact.

The results of the first collected samples were published Aug. 9, before the discharge of treated water from the complex commenced on Aug. 24. The water had been used to cool melted nuclear fuel at the plant but has undergone a treatment process that removes most radionuclides except tritium.

I mean, you are correct, it was not two fish. But is 64 fish some sort of good sample size?

Given the results, it is significant.

Follow up question: does this type of thing accumulate in small fish and then concentrate in larger and larger fish?

No, tritium is treated by organisms just like normal H2O, bioaccumulation is no problem.
