California Department of Fish and Wildlife Director Charlton H. Bonham is extending the emergency commercial rock crab fishery closure for areas north of Bodega Bay, which was due to expire May 16. Meanwhile, all crab — Dungeness and rock — is deemed safe to eat south of the North Bay.
State health agencies determined last fall that rock crabs north of Pigeon Point to the Oregon border had unhealthy levels of domoic acid and recommended a commercial fishery closure. Subsequently, Bonham submitted an emergency rule to close the commercial rock crab fishery north of Pigeon Point. That authority is new to the director this year.
Following new recommendations of state health agencies, the CDFW director announced on Feb. 10 that the open area of the commercial rock crab fishery had been extended northward to Bodega Bay in Sonoma County. CDFW is continuing to work closely with state health agencies to monitor levels of domoic acid in rock crabs and other species not affected by this closure.
This closure shall remain in effect until the director of the Office of Environmental Health Hazard Assessment, in consultation with the Department of Public Health, determines that domoic acid levels no longer pose a significant risk to public health and recommends the fishery be open.
The recreational fishery for rock crab remained open statewide, but the California Department of Public Health issued a warning to avoid consuming the viscera of rock crab caught in the closure area. As a precaution, state authorities recommend avoiding the viscera in Dungeness crab as well.
State officials continue to test domoic acid levels in crab along the coast to determine when the fishery can safely be opened.
Domoic acid is a potent neurotoxin produced by a naturally occurring marine alga. Those levels can be increased under certain ocean conditions.
