September 22, 2021 — Federal biologist Erin Fedewa boarded a research vessel in June in Dutch Harbor, Alaska, and journeyed to a swath of the Bering Sea that typically yields an abundance of young snow crab in annual surveys.
Not this summer. At this spot, and elsewhere, the sampling nets came up with stunningly few — a more than 99% drop in immature females compared to those found just three years earlier.
Biologists also found significant downturns in the numbers of mature snow crab as they painstakingly sorted through the sea life they hauled up.
“The juveniles obviously were a red flag, but just about every size of snow crab were in dramatic decline,” Fedewa said. “It’s very scary.”
This collapse in the Bering Sea snow crab population comes amid a decade of rapid climatic changes, which have scrambled one of the most productive marine ecosystems on the planet in ways that scientists are just beginning to understand. The changes are forcing them to reconsider how they develop models to forecast harvest seasons.
