October 24, 2025 — After 3 weeks crisscrossing the frigid Bering Sea, much of it spent wrangling crabs scooped from the sea floor, Erin Fedewa faced a final challenge: getting nearly 200 live animals to a lab 3000 kilometers away in less than 24 hours.
“This is always a little bit risky,” said Fedewa, a fisheries biologist from the U.S. National Oceanic and Atmospheric Administration (NOAA), as she stood on the deck of the Northwest Explorer, a 49-meter trawler converted for a summer research trip, while the ship was moored at Nome’s port.
She lifted the lid on a waist-high blue plastic box and peered inside. There, immersed in 900 liters of seawater, lay her charges—dozens of what appeared to be enormous spiders, their leg spans the size of hub caps. Chunks of sea ice bobbed beside these snow crabs (Chionoecetes opilio), stirred by a pump to keep the animals bathed in the coldest water possible.
For Fedewa, success would mean the difference between months of productive research and de facto crab stew. She learned this the hard way in 2022, when the ship on which she was working docked in Nome and scientists filled the crab tanks with water siphoned directly from Norton Sound, a shallow, warmer part of the Bering Sea. “They just died,” she said.
That small fiasco is a microcosm of the recent fate of snow crabs in much of the Bering Sea. An unprecedented underwater heat wave there in 2018 and ’19 set off a chain reaction that led to the disappearance of an estimated 47 billion crabs, one of the largest marine die-offs ever documented. Suddenly, a $150 million fishery mythologized in the Deadliest Catch reality TV show found itself with no catch at all. State regulators for the first time banned Bering Sea snow crab fishing in 2023 and ’24, and the U.S. government declared a federal fishery disaster. The fishery reopened this year. But crabbing boats were only allowed to haul in a tiny fraction of what they had caught previously. The collapse “has had massive impacts,” says Scott Goodman, a fisheries biologist and executive director of the Bering Sea Fisheries Research Foundation, which is funded by the crab industry.
