CNN — 

The Alaska snow crab harvest has been canceled for the first time ever after billions of the crustaceans have disappeared from the cold, treacherous waters of the Bering Sea in recent years.

The Alaska Board of Fisheries and North Pacific Fishery Management Council announced last week that the population of snow crab in the Bering Sea fell below the regulatory threshold to open up the fishery.

But the actual numbers behind that decision are shocking: The snow crab population shrank from around 8 billion in 2018 to 1 billion in 2021, according to Benjamin Daly, a researcher with the Alaska Department of Fish and Game.

“Snow crab is by far the most abundant of all the Bering Sea crab species that is caught commercially,” Daly told CNN. “So the shock and awe of many billions missing from the population is worth noting – and that includes all the females and babies.”

Snow crabs are cold-water species and found overwhelmingly in areas where water temperatures are below 2 degrees Celsius, Litzow says. As oceans warm and sea ice disappears, the ocean around Alaska is becoming inhospitable for the species.

“There have been a number of attribution studies that have looked at specific temperatures in the Bering Sea or Bering Sea ice cover in 2018, and in those attribution studies, they’ve concluded that those temperatures and low-ice conditions in the Bering sea are a consequence of global warming,” Litzow said.
