The port is in trouble again, dense¹ sardine² carcasses appear in the fishing port of Shima City, Mie Prefecture, Japan, a large number of dead fish are piled up on the shore, so many that it is difficult for fishing boats to move an inch.

Now the local authorities have recycled the sardine carcasses, which weigh about 100 tons according to current information.

In such a situation, it is easy to associate the death of a large number of sardines³ with the nuclear wastewater, but the current theory from the Japanese side is that the death of the sardines may be due to "lack of oxygen".

The first die-off occurred in Hakodate on Japan’s northernmost main island of Hokkaido on the morning of Dec. 7. The sheer volume of fish that washed ashore⁴ created a silver blanket along a stretch of beach about a kilometre long.
