According to Japan's "Yomiuri Shimbun" reported on the 12th, a large number of sardine carcasses appeared off the coast of Japan, and the reason is not known at present. There have been no marine vessel accidents in the waters where the carcasses of these sardines have been present. This happened before the earthquake, but some netizens speculated that it was because of nuclear wastewater pollution in Japan. "Natural disasters" or "man-made disasters" still have to wait for the conclusions of Japanese investigations and research.
This is not the first time that a large number of fish carcasses have appeared
At the beginning of this year, when the epidemic was not yet subsiding, a large number of dead fish were found near Miyake Island and on the beach. A large number of fish carcasses were washed ashore, and from a distance, the beach was covered with white flowers, and the type of fish was also sardines. Miyake Island is an island centered on an active volcano, so Japanese researchers believe it is related to the phenomenon of volcanic eruptions and earthquakes, as well as changes in the seawater environment due to changes in sea temperature, so that some sardines cannot survive.
In the early years, a large number of sardine carcasses also appeared near the port of Hokkaido, Japan, and the local people believed that it was a harbinger before the earthquake, and some researchers believed that the abnormal flow of current on the seabed changed the living environment of the fish, making the fish unable to survive. Things like this happen a lot in Japan, and many residents think it is a harbinger of natural disasters.
"Man-made" factors
In late November, Nippon Electric Power Corporation announced that two staff members had inhaled radioactive material. Previously, Japan publicly stated that it would treat nuclear wastewater to a "drinkable" standard and then discharge it into the sea, can it really treat nuclear wastewater to a drinkable standard? No radioactivity after treatment? This kind of behavior, which harms both others and oneself, has also been supported by the United States.
The 3.11 Earthquake in Japan is of great concern and suspicion. After the magnitude 9.0 earthquake, a massive tsunami occurred in Japan, with unexplained undersea whirlpools appearing on the surface of the sea, as well as nuclear leaks. Regarding the large whirlpool that has no reason, Japanese experts explain that it is because of the earth's crustal activity that caused earthquakes, but also caused changes in the seabed, and the phenomenon of the whirlpool was reversed.
In addition to this, there is also the factor of marine pollution. According to researchers' research on marine life, the harm of marine pollution to marine life is incalculable. Not only is it plastic waste that we can see with the naked eye, but there are also a lot of plastic fragments in the seawater that we can't see, and these substances are endangering marine life.
"Natural disaster" factor
Due to Japan's special geographical location, natural disasters such as earthquakes and tsunamis occur frequently in Japan, and some phenomena are considered to be precursors before earthquakes and tsunamis. Just like the incident of a large number of fish deaths in Japan, there may also be bizarre deep-sea fish, in addition to the "warning" of fish, there are flocks of crows as if to cover the sky, cats and dogs behave differently than usual, and so on.
In addition to this, changes in submarine volcanoes can also lead to a large number of fish deaths. At the end of October 2021, the eruption of the submarine volcano on the Japanese island of Ogasawara Islands led to the emergence of a large number of pumice stones, and through the study of dead fish, it was found that these fish had a large amount of pumice in their stomach bags, which proved that a large number of fish died due to accidental eating of these pumice stones, and the eruption of this volcano may even affect multiple nuclear power plants.
