Alaska’s Snow Crab Collapse Is Likely Tied to Climate Change
Declining populations of snow crabs and red king crabs have prompted officials to suspend harvesting for the season, a blow to the state’s seafood industry.

“We’re still trying to figure it out, but certainly there’s very clear signs of the role of climate change in the collapse,” said Michael Litzow, shellfish assessment program manager at the National Oceanic and Atmospheric Administration (NOAA), which runs an annual survey of Bering Sea snow crab numbers. (Snow crabs are also found in the Beaufort and Chukchi seas off Alaska.)
