October 29, 2026 — Scientists at the Alaska Fisheries Science Center’s Kodiak Laboratory recently completed research on how certain hybrid crab populations have increased in Alaska’s Bering Sea following a marine heatwave and subsequent mass die-off events from 2018 to 2019.
“These results are unprecedented,” study lead Erin Fedewa said in a NOAA release. “We were shocked by the magnitude of the hybrid surge while analyzing data from the 2025 Eastern Bering Sea bottom trawl survey. It immediately became clear that this ecological response would ripple through to fisheries management.”
