Ocean acidification could threaten Alaska crab populations

KODIAK, Alaska (AP) – Alaska researchers warn that the changing levels of ocean acidity could have grave consequences for red king crab populations in the Bering Sea.

The acidity of waters off Alaska could change dramatically over the next 50 years, leading to possible crab stock failure in about 100 years, said Robert Foy, director of the Alaska Fisheries Science Center’s Kodiak Laboratory.

A change in pH, the scale of acidity, is occurring as more carbon dioxide is dissolved in the water, Alaska’s Energy Desk reported . Researchers expect ocean acidification to occur faster at locations in h...
