On the morning of the 7th, a large number of sardines and other fish were found washed up on the coast of Hakodate City, Hokkaido, and Hakodate City and others are discussing what to do with the large number of dead fish.
At around 7 a.m. on the 8th, a citizen reported to the police that "a large number of fish were washed up on the beach" in Hamamachi, Hakodate City, and the city was also contacted.
As of noon on the 7th, a large number of sardines and other fish had washed up on the beach at the site over a range of about 1 kilometer.
According to the local Toi Fishery Cooperative, although fish have washed up on the coast in the past, it is rare to see such a large amount, and a man in his 80s who visited the site said he was "surprised."
According to Hokkaido, the oxygen concentration in the sea decreases in the process of decomposing a large number of dead fish, and there is a possibility that sea life will be affected, so Hakodate City is discussing with the province what to do with the large number of dead fish.
Expert: "There is no significant impact on the ecosystem as a whole"
Regarding the large number of fish washed up on the shore, Mitsuhiro Nakaya, an associate professor at the Graduate School of Hokkaido University who is familiar with the behavior of marine organisms, said, "With the drop in seawater temperature in eastern Hokkaido, schools of fish descended from the east to the southern part of Hokkaido and escaped from predators such as dolphins and tuna. If you look at the ecosystem as a whole, it won't have a big impact."
