    News from SeafoodMedia on November 25 that global warming has caused ocean temperatures to rise, which has had a devastating impact on Japan's fishing industry, and fish in Japanese waters are getting thinner, and fish that should have been caught are now moving
    north.
     
    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.
     
    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.
