Researchers are scrambling to understand crabs' collapse, with seas warmed by climate change as one theory. Preliminary data from this year's survey suggest another year of closed or severely limited fisheries
Gabriel Prout worked four seasons on his father’s crab boat, the Silver Spray, before joining his two brothers in 2020 to buy a half-interest plus access rights for a snow crab fishery that’s typically the largest and richest in the Bering Sea. Then in 2021, disaster: an annual survey found crabs crashing to an all-time low. The red king crab fishery was closed; the snow crab fishery cut to a tenth of the previous year’s take.
Researchers are scrambling to understand crabs’ collapse, with seas warmed by climate change as one theory. Preliminary data from this year’s survey suggest another year of closed or severely limited fisheries, with decisions on crab catch limits expected in early October shortly before the season traditionally opens.
When fisheries get closed “you displace a lot of boats and a lot of crew,” he said. “It makes people start hunting for more opportunity.” Researchers this year brought samples of crab back to Kodiak for further analysis, exploring how snow crab respond to stress in their environment, including rising heat.
Researchers and managers have started examining data from this year’s survey. It will help determine what crab fisheries might open this winter and decisions on each kind of crab are expected some time in early October.
