With the discharge of nuclear sewage into the sea, there have been frequent reports of "a large number of dead fish on the coast of Japan". In early December, local media reported that a large number of sardine carcasses had washed up on the beach off the coast of Hakodate City, Hokkaido, Japan, and it was unclear why the sardine carcasses had washed up on the beach.
Recently, a large number of dead fish have appeared off the coast of Japan, and the location of the incident is the port of Poche in Shima City, Mie Prefecture, Japan. According to local media reports, the number of dead fish in Poche fishing port was so large that it was difficult for fishing boats to move an inch. This amount must be imagined by everyone, so many large number of dead fish carcasses, fishermen want to drive fishing boats to the sea can not be opened, need to clean up all these dead fish carcasses before driving away the fishing boat.
Since the incident, the dead fish carcasses have been recovered, and as of December 14, 85 tons have been recovered. At present, it is expected that the dead fish carcasses have been completely cleaned up. This is the second time this month that there has been a large number of dead fish in Hokkaido on December 7.
It is understood that Shima City is an administrative city in Mie Prefecture, Japan, located in the southern part of the Shima Peninsula. It was established on October 1, 2004 and was formed by the merger of five towns: Hamashima, O, Shima, Aer, and Isobe.
What is the reason for the frequent occurrence of a large number of dead fish in Japan in a short period of time?
First of all, it may be caused by a lack of oxygen in the fish. Hypoxia occurs when the amount of oxygen in a body of water is reduced to the point where it cannot meet the normal breathing needs of the fish. This can be caused by eutrophication in water, weather changes, water pollution, etc.
Secondly, it may be meteorological conditions. Weather changes, abnormal meteorological conditions (e.g., extreme heat, cold, heavy rain, etc.) can cause a decrease in oxygen levels in water bodies, which can affect the survival of fish.
Finally, it could be ecosystem changes. Major changes in the ecosystem of waters, such as the disappearance of aquatic vegetation or the introduction of alien species, can lead to the loss of suitable habitat for fish.
It is important to note that a detailed analysis of the specific situation often requires an on-site investigation to determine the exact cause of the fish kill. At present, according to the explanation of relevant Japanese officials, it is related to the lack of oxygen in fish, and has nothing to do with the discharge of Fukushima nuclear sewage into the sea, and the specific details are still uncertain.
Generally speaking, there have been many cases of dead fish in Japan since the discharge of nuclear sewage into the sea, and this situation did not occur before the discharge into the sea. No matter how the local people respond, if they don't stop discharging nuclear sewage into the sea for a day, our country will definitely not import Japanese seafood. Even if the discharge of nuclear sewage into the sea is stopped now, it is estimated that the local seafood will not be eaten.
