Experts warn that Hokkaido's salmon will eventually disappear
.

In Shioma City, Miyagi Prefecture, the market is lined with huge bluefin tuna, as well as boxes of squid and halibut

Despite the port city's abundant produce, fishermen and wholesalers say they are catching fewer fish, fish are getting thinner, rising water temperatures are weakening fisheries in the northeast, and fish prices are struggling to rise

Changes in the marine environment due to global warming are believed to be responsible
for the decline in Japan's catches.
A cloud of warm water appears in the black currents of the Pacific Ocean, pushing migratory spawning routes inshore, where food is scarce, resulting in reduced catches and reduced quality

Shinichi Ito, a professor at the University of Tokyo's Institute of Atmosphere and Oceanology, said rising water temperatures had caused some fish, such as yellowtails and mackerel, to land in different places than in
the past.
the past.
These fish are being fished farther north than they were 10 years ago, arguably as a result of
climate change.
In the case of salmon, they cannot regulate their body temperature, so they have to move
north.
According to Shinichi Ito's simulations of changes in sea temperature, there may not be salmon to catch
even in the waters of Hokkaido in the coming decades.
