Ocean acidification threatens Alaska's multimillion-dollar crab industry
A crew member aboard the Arctic Hunter beats ice from the knuckle boom before using it to pull crab pots aboard.
New research earlier this year shows that Bristol Bay red king crab — the supersized monster that has come to symbolize the fortunes of Alaska’s crab fleet — could fall victim to the changing chemistry of the oceans.
Barring a hasty reduction in carbon-dioxide emissions — or evidence that the creatures could acclimate to changing sea conditions — a team of scientists fears Alaska’s $100 million red king crab fishery could crash in decades to come.
That grim possibility also raises alarm about the crab fleet’s other major moneymaker, snow crab.
“With red king crab, it’s all doom and gloom,” said Robert Foy, who oversaw the crab research for the National Oceanic and Atmospheric Administration (NOAA) in Kodiak, Alaska. “With snow crab, there’s so little known we just can’t say. But we don’t see anything from our experience that’s good for any of these crab. Some is just not as bad as others.”
