Japan has many earthquakes and has been plagued by earthquakes for a long time. In Japan, a country prone to earthquakes, there have long been legends and myths about the relationship between catfish and earthquakes. Catfish have a nervous and delicate personality, so they often become violent and jump around. In the past, Japanese people believed that earthquakes were caused by large catfish living underground that became violent.
200 years ago, catfish paintings, which were associated with catfish and earthquakes, became popular. This is a picture depicting the people punishing the giant catfish that caused the earthquake. This is how the Japanese people 200 years ago expressed the causes of earthquakes and how to prevent them.
Even in the 21st century, earthquake prediction is extremely difficult, and the current science limit is that the probability of an earthquake occurring in the future is XX percent over the next 30 years. It is not yet scientifically clear whether catfish can predict earthquakes. Even so, catfish are extremely sensitive to weak electricity and vibrations in the water, so they may sense electromagnetic waves or underground currents that occur before an earthquake, causing them to behave abnormally.
The field of earthquake prediction is left to future research. In addition to physical and geological methods, I think biological approaches are also good.
Japanese people have been fishing catfish as food fish since ancient times. Eel has a lot of fat and tastes heavy, but catfish has a refreshing and elegant taste. Catfish contains protein and collagen, making it a fish suitable for women, children, and the elderly.
Catfish is a freshwater fish, but there is also a catfish called Japanese eel catfish plotsus japonicus in the sea in Japan. Japanese eel catfish have poisonous stingers on their dorsal fins, so it will be painful if you touch them with bare hands.
