A large number of dead sardines appeared in Hokkaido, Japan. Why did these fish die?

A tragic scene occurred on the coastline of Wakkanai City, Hokkaido, Japan. A huge number of sardines died. Due to the cold weather, heavy snow covered the dead sardines that washed up on the coast. The scene was grand and sparked heated discussions.

Earthquakes of different sizes occur every day. It may be logically unreasonable to judge by the death of fish. However, this large-scale fish death occurred in the Japanese earthquake. It may be It's not a coincidence, why do you say that? After the 7.3-magnitude earthquake in Japan, two nuclear power plants in Fukushima leaked slightly, so many people suspected that it was related to nuclear pollution, which caused the death of sardines.

According to normal circumstances, since we are in the ocean area, the environment must be the most important factor affecting the survival of organisms. For example, what we often talk about - whether the water environment meets the standards, the impact of ocean temperature on the survival of organisms, etc., may lead to the death of a large number of organisms in an unadapted state.

Another possibility is that this large-scale species death phenomenon is caused by the rare and severe red tide. The red tide phenomenon is not a strange and good thing. The red tide is also called red tide by us and also known as red tide internationally. as "harmful algae" or "red ghost". This phenomenon is an anomaly in the marine ecosystem, which is caused by the explosive proliferation of red tide algae in the marine family under specific environmental conditions. As long as it appears, it will trigger a crisis for the marine ecosystem.

So let’s explain it comprehensively. The large number of dead sardines in Hokkaido, Japan may be a normal phenomenon and not a strange thing. It is basically impossible to connect it with the earthquake, so everyone Don't worry, earthquakes are normal and are natural phenomena. Nowadays, earthquake early warning is the only thing that helps mankind. Earthquake early warning is not earthquake prediction. It is also based on after the earthquake occurs. Therefore, there are no precursors of earthquakes. Don’t be misunderstood by different concepts. Based on science.
