Recreational Dungeness Crab Fishery Delayed in Northern California: What You Need to Know
The excitement of the recreational Dungeness crab fishery season is palpable among enthusiasts and families along the Northern California coast. However, this year, the anticipation has been tempered by a significant public health concern. As of Saturday, November 2, the recreational fishery will officially open, but not without restrictions in a specific area due to elevated levels of a harmful toxin.
Health Advisory and Closure Area
State health agencies have issued a warning regarding the presence of domoic acid in Dungeness crab populations along a stretch of Northern California waters. This area extends from the California/Oregon state line (42° 0.00’ N latitude) down to the southern boundary of the Reading Rock State Marine Reserve (41° 17.6’ N latitude) in Humboldt County. The California Department of Fish and Wildlife (CDFW) has acted swiftly on this recommendation, prohibiting the recreational take and possession of Dungeness crab in these waters until further notice.
Understanding Domoic Acid
Domoic acid is a potent neurotoxin produced by a marine alga known as Pseudo-nitzschia. Under certain oceanic conditions, this single-celled organism can proliferate, leading to harmful algal blooms. While the algae itself remains unaffected, the toxin can accumulate in shellfish and other marine life, posing a serious risk to human health.
At low levels, exposure to domoic acid can lead to symptoms such as nausea, diarrhea, and dizziness. However, at higher concentrations, the effects can be much more severe, potentially resulting in persistent short-term memory loss, seizures, and in extreme cases, death. This makes the current health advisory particularly critical for those who enjoy recreational crabbing.
Monitoring and Future Updates
The delay in the recreational Dungeness crab fishery will remain in effect until the Office of Environmental Health Hazard Assessment, in collaboration with the State Public Health Officer of the California Department of Public Health (CDPH), determines that the risk posed by domoic acid has subsided. Regular sampling of the affected waters will be conducted, and should conditions improve, the CDFW will promptly announce any changes to the current restrictions.
In accordance with Fish and Game Code, section 5523, the CDFW Director will keep the California Fish and Game Commission informed about the situation and will request a public discussion at the Commission’s next scheduled meeting.
