October 28, 2022 — Fishing regulators and the seafood industry are grappling with the possibility that some once-profitable species that have declined with climate change might not come back.
Several marketable species harvested by U.S. fishermen are the subject of quota cuts, seasonal closures and other restrictions as populations have fallen and waters have warmed. In some instances, such as the groundfishing industry for species like flounder in the Northeast, the changing environment has made it harder for fish to recover from years of overfishing that already taxed the population.
Officials in Alaska have canceled the fall Bristol Bay red king crab harvest and winter snow crab harvest, dealing a blow to the Bering Sea crab industry that is sometimes worth more than $200 million a year, as populations have declined in the face of warming waters. The Atlantic cod fishery, once the lifeblood industry of New England, is now essentially shuttered. But even with depleted populations imperiled by climate change, it’s rare for regulators to completely shut down a fishery, as they’re considering doing for New England shrimp.
The Northern shrimp, once a seafood delicacy, has been subject to a fishing moratorium since 2014. Scientists believe warming waters are wiping out their populations and they won’t be coming back. So the regulatory Atlantic States Marine Fisheries Commission is now considering making that moratorium permanent, essentially ending the centuries-old harvest of the shrimp.
It’s a stark siren for several species caught by U.S. fishermen that regulators say are on the brink. Others include softshell clams, winter flounder, Alaskan snow crabs and Chinook salmon.
