Recently, a large number of dead fish have washed ashore on the shores of Boxe Fishing Port in Shima City, Mie Prefecture, and Hakodate City, Hokkaido, which has attracted widespread attention from the society. In both cases, the number of dead fish was so large that it was difficult for fishing boats to navigate, causing great distress to local fishermen. Up to now, 85 tons of dead fish have been killed in Shima City.
Local fishermen say this is the first time they have seen so many dead fish floating on the surface, a phenomenon that raises concerns about possible changes to the marine ecosystem. The official explanation said that the fish may have died due to lack of oxygen, and stressed that it had nothing to do with the discharge of nuclear-contaminated water from the Fukushima nuclear power plant into the sea.
In the city of Hakodate, Hokkaido, a large number of sardine carcasses washed up on the beach, about 1 km long. Local residents said they had never seen such a scene, and some even wanted to take the dead fish home to eat, but officials urged against doing so and a detailed investigation was underway. Researchers at the Hakodate City Fisheries Research Institute have suggested several possible causes, including being chased by large fish or migrating with cold ocean currents, but the exact cause is still to be identified.
These two incidents not only have an impact on local fisheries, but also raise concerns about changes in the marine environment and the stability of ecosystems. With global climate change and the increase in human activities, marine ecosystems are facing more and more challenges. The presence of a large number of dead fish may be a signal of changes in the marine ecosystem, suggesting that we need to pay more attention to the protection and balance of the marine environment.
In addition, these incidents also serve as a reminder to the public to remain vigilant in the face of anomalies in the natural world and to rely on the investigations and recommendations of professional bodies to avoid inappropriate actions due to misinformation. At the same time, they are a warning to the global community that we must take more proactive measures to protect our marine environment and ensure the health of marine life and the long-term stability of ecosystems. It is only through global cooperation and joint efforts that we can effectively address the challenges posed by changes in the marine environment and protect the precious natural resources of this planet.
