It's becoming a regular part of the Dungeness crab season on the West Coast: waiting for domoic acid levels to drop into safe ranges.
When they're up, the crab fishery is closed to protect human health. It's open now, after a delay.
Oregon State researcher Morgaine McKibben looked into the ocean conditions that appear to contribute to the rise in domoic acid, which is a neurotoxin.
The work McKibben and five other researchers produced is published in a scientific journal.
McKibben joins us to talk crabs and razor clams and ocean conditions.
