California Opens Recreational Dungeness Crab Season With Trap Restrictions and Northern Delays
The recreational Dungeness crab season will open under trap restrictions beginning November 7, 2026, except in a portion of Northern California where it has been delayed due to a public health hazard, according to wildlife.ca.gov.
State health agencies determined that Dungeness crab collected north of Fort Bragg, spanning southern Humboldt County and northern Mendocino County, carry unhealthy levels of domoic acid. Following this guidance, California Department of Fish and Wildlife (CDFW) Director Meghan Hertel recommended delaying the opening of the recreational fishery in state waters from Cape Mendocino down to the Ten Mile State Marine Reserve. Recreational take and possession of Dungeness crab remain strictly prohibited in these closed waters.
Trap Restrictions and Commercial Fishery Delays Across Fishing Zones 1 Through 5
Beyond the localized health closures, the use of recreational crab traps is heavily restricted (PDF) from the California/Oregon border down to Point Conception across Fishing Zones 1 through 5. This restriction remains in effect until at least January 1, 2027, driven by a high volume of confirmed whale entanglements this year alongside a significant abundance of humpback whales across the fishing grounds. CDFW also issued a Fleet Advisory urging crabbers to avoid setting gear where whales are actively present.
This gear limitation does not apply to hoop nets and crab snares, though anglers must service all hoop nets every two hours and cannot leave them unattended. Meanwhile, the commercial Dungeness crab fishery will be delayed (PDF) across that same expanse from the state line to Point Conception until at least January 1, 2027. State regulations mandate these protective measures to minimize additional entanglements and allow humpback whales to migrate out of California waters before commercial operations commence.
“CDFW remains committed to working collaboratively with all sectors across California to protect whale and turtles from entanglements in fishing gear,” Hertel said. “Partnerships are more important than ever as we work together to protect endangered whales and turtles and our fishing communities in the face of increasing disruptions from our changing climate.”
Public Health Risks of Domoic Acid and Upcoming Risk Assessments
The neurotoxin driving the Northern California closure, domoic acid, is produced naturally by Pseudo-nitzschia, a single-celled marine alga that thrives under specific ocean conditions. While the toxin accumulates in shellfish, invertebrates, and occasionally fish without harming the marine organisms themselves, it poses severe risks to humans. Low-level exposure triggers nausea, diarrhea, and dizziness, whereas higher concentrations cause persistent short-term memory loss, seizures, and in severe cases, fatality.
The regional closure will stay enforced until the Office of Environmental Health Hazard Assessment, consulting with the State Public Health Officer at the California Department of Public Health (CDPH), verifies that domoic acid no longer presents a threat. For the rest of the coastline, CDFW plans to conduct its next risk assessment in mid-December. That review will incorporate recommendations from the Dungeness Crab Fishing Gear Working Group to decide whether commercial operations can start and recreational trap limits can lift around the new year.
