Climate change could cause some fish species to shrink by nearly 25%

A new study that modeled the impact of climate change on more than 600 fish species says that most of those species could shrink by between 14 and 24 percent by the year 2050. Additionally, as the concentration of oxygen in the Earth’s waters decreases, some species may move away from equatorial waters toward the Arctic. The study, conducted by researchers from the University of British Columbia, Princeton University and the National Oceanic and Atmospheric Administration, has broad implications — not only for the Earth’s ecosystems, but for the seafood industry as well as sport fishermen. If that doesn’t get you excited, take this theoretical figure: in 2011, Alaska brought home 5.4 billion pounds of seafood worth $1.9 billion, by far the most among U.S. states. If that catch were reduced by 25 percent, it would mean a loss of 1.35 billion pounds and $475 million from state fisheries. Alaska Dispatch
