On 5/28/2015, Tokyo Sea Life Park announced 12 of 29 mackerel tunas died in the tank, where 158 of 159 tunas have died since the end of last year.

Since the end of March, they have been adding 2 scalloped hammerheads and 500 Takasagos in this tank in order to check the quality of water.

They also added 30 striped bonitos on 5/15 and 29 mackerel tunas on 5/22. However, 12 mackerel tunas have been dead by 5/28.

They found most of them had their spines or head broken just like the 158 former tunas, which died since the end of last year.


It is proved that the reason of death still remains in the keeping circumstances but it is not identified yet.

Le 28 mai 2015, le Tokyo Sea Life Park annonce que 12 des 29 Euthynnus affinis sont morts dans leur bassin, là où 158 des 159 thons étaient morts depuis la fin de l’an dernier.

Depuis fin mars, dans ce bassin ils ont ajouté 2 requins marteau et 500 Takasagos (Ambassis interrupta) pour en contrôler la qualité de l’eau.
Ils y ont mis aussi 30 bonites orientales le 15 mai et 29 Euthynnus affinis le 22. Néanmoins 12 Euthynnus affinis étaient morts au 28 mai.
Ils ont vu qu la plupart d’entre eux avaient la colonne vertébrale ou la tête cassées exactement comme les 158 thons précédents, ceux morts depuis la fin de l’an dernier.

Il est prouvé que la raison de ces morts réside dans les conditions de captivité mais on ne la connaît pas encore.


About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
