A Section of the Commercial Spiny Lobster Fishery Closure around Anacapa Island has been Lifted

Today the California Department of Fish and Wildlife (CDFW) Director Charlton H. Bonham lifted a portion of the commercial fishery closure around Anacapa Island east of 119°30.000’ W. longitude and north of 34°00.000’ N. latitude as recommended by state health agencies. According to the notice from the Director of the Office of Environmental Health Hazard Assessments (OEHHA), sampling of spiny lobster and analysis of samples by California Department of Public Health (CDPH) laboratories indicates that consumption of spiny lobster taken from this area no longer poses a significant threat for domoic acid exposure.

On October 24, 2017 State health agencies determined that spiny lobster near Anacapa Island, Ventura County and the east end of Santa Cruz Island, Santa Barbara County had unhealthy levels of domoic acid and recommended closure of the commercial fishery in this area.

Except for state waters east of 119°30.000’ W. longitude and north of 34°00.000’ N. latitude, the commercial closure remains in effect in all state waters around Santa Cruz and Anacapa Islands east of 119°40.000’ W. longitude, and west of 119°20.000’ W. longitude. State waters extends three nautical miles beyond outermost islands, reefs and rocks. The recreational fishery for spiny lobster remains open statewide with a warning from CDPH to recreational anglers to avoid consuming the viscera (tomalley) of spiny lobster taken from the closed area.

This closure shall remain in effect until the Director of OEHHA, in consultation with the State Public Health Officer at CDPH, determines that domoic acid no longer poses a significant risk to public health and recommends the fishery be open in this area. CDFW will continue to coordinate with CDPH and OEHHA to test domoic acid levels in spiny lobster to determine when the fishery can safely be opened in the closed area.

Domoic acid is a potent neurotoxin produced by a naturally occurring marine alga, whose levels can be increased under certain ocean conditions. State and federal laws prohibit the commercial distribution of seafood products that contain domoic acid levels above the federal action level, which is 20 parts per million in the viscera of spiny lobster.

Commercial Spiny Lobster Fishery Closed at Anacapa Island and the East End of Santa Cruz Island Due to Public Health Hazard

California Department of Fish and Wildlife (CDFW) Director Charlton H. Bonham has enacted a commercial spiny lobster fishery closure effective immediately.

State health agencies determined that spiny lobster near Anacapa Island, Ventura County and the east end of Santa Cruz Island, Santa Barbara County had unhealthy levels of domoic acid and recommended closure of the commercial fishery. The recreational fishery for spiny lobster remains open statewide with a warning from the California Department of Public Health (CDPH) to recreational anglers to avoid consuming the viscera (tomalley) of spiny lobster.

The commercial closure includes all state waters around Santa Cruz and Anacapa Islands east of 119° 40.000’ W. longitude, and west of 119° 20.000’ W. longitude. State waters extend three nautical miles beyond outermost islands, reefs and rocks.

This closure shall remain in effect until the Director of the Office of Environmental Health Hazard Assessment (OEHHA), in consultation with the State Public Health Officer at CDPH, determines that domoic acid no longer poses a significant risk to public health and recommends the fishery be open. CDFW will continue to coordinate with CDPH and OEHHA to test domoic acid levels in spiny lobster to determine when the fishery can safely be opened.

Pursuant to Fish and Game Code Section 5523, the Director of CDFW will notify the Fish and Game Commission of the closure and request that the Commission schedule a public discussion of the closure at its next scheduled meeting.

Domoic acid is a potent neurotoxin produced by a naturally occurring marine alga, whose levels can be increased under certain ocean conditions. State and federal laws prohibit the commercial distribution of seafood products that contain domoic acid levels above the federal action level, which is 20 parts per million in the viscera of spiny lobster.

Fish and Wildlife Director Extends Commercial Rock Crab Fishery Closure in Northern California Due to Public Health Hazard

 

California Department of Fish and Wildlife Director Charlton H. Bonham, under new authority granted this year, has acted to extend the emergency commercial rock crab fishery closure that was due to expire on May 16.

State health agencies determined last fall that rock crabs north of Pigeon Point (37° 11’ N. lat.) to the Oregon border had unhealthy levels of domoic acid and recommended a commercial fishery closure. Subsequently, Director Bonham submitted an emergency rulemaking to close the commercial rock crab fishery north of Pigeon Point. The recreational fishery for rock crab remained open statewide with a warning from the California Department of Public Health (CDPH) to recreational anglers to avoid consuming the viscera of rock crab caught in the closure area. Following the recommendation of state health agencies, the CDFW Director announced on February 10, 2017 that the open area of the commercial rock crab fishery had been extended northward to Bodega Bay, Sonoma County (38° 18′ N. Lat.).

Bonham’s decision today extends the emergency commercial rock crab fishery closure that was due to expire on May 16. 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 (OEHHA), in consultation with the Director of CDPH, determines that domoic acid levels no longer pose a significant risk to public health and recommends the fishery be open. CDFW will continue to coordinate with CDPH and OEHHA 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, whose levels can be increased under certain ocean conditions.

Commercial Rock Crab Fishery Now Extends to Bodega Bay

Following the recommendation of state health agencies, the California Department of Fish and Wildlife (CDFW) announced today that it will extend the open area of the commercial rock crab fishery northward to Bodega Bay in Sonoma County.

  • On Feb. 10 the commercial rock crab fishery is open from 38° 18′ N. Lat. (Bodega Bay, Sonoma County) south to the California/Mexico border.

At the recommendation of the state Office of Environmental Health Hazard Assessment (OEHHA), CDFW Director Charlton H. Bonham submitted to the Office of Administrative Law an emergency rulemaking to close the commercial rock crab fishery north of Pigeon Point, San Mateo County. Because of this, on Nov. 8, OEHHA, in consultation with the California Department of Public Health (CDPH), recommended to CDFW to close the commercial rock crab fishery north of Pigeon Point. State and federal laws prohibit the commercial distribution of seafood products that contain domoic acid levels above the federal action level of 30 parts per million (ppm) in the viscera. The recreational fishery for rock crab remains open statewide with a warning from CDPH to recreational anglers to avoid consuming the viscera of rock crab caught north of Bodega Bay.

Closure of the commercial rock crab fishery north of Bodega Bay shall remain in effect until the Director of OEHHA, in consultation with the Director of CDPH, determines that domoic acid levels no longer pose a significant risk to public health and recommends the fishery be open. In the meantime, CDFW will continue to coordinate with CDPH and OEHHA to test domoic acid levels in rock crab within the closure area of the coast. CDPH, in conjunction with CDFW, has been actively testing crabs since early September. The most recent test results showed that domoic acid in rock crabs from Bodega Bay and Point Reyes had fallen below the alert level of 30 ppm in their viscera.

Domoic acid is a potent neurotoxin that can accumulate in shellfish, other invertebrates and sometimes fish. It causes illness and sometimes death in a variety of birds and marine mammals that consume affected organisms. At low levels, domoic acid exposure can cause nausea, diarrhea and dizziness in humans. At higher levels, it can cause persistent short-term memory loss, seizures and can in some cases be fatal.

Recreational Razor Clam Fishery Closure in Humboldt and Del Norte Counties Extended Due to Ongoing Public Health Concerns

Under new authority granted this year, California Department of Fish and Wildlife Director Charlton H. Bonham has acted to extend the closure of the recreational razor clam fishery in Humboldt and Del Norte counties due to continued high levels of domoic acid, as determined by the Office of Environmental Health Hazard Assessment in consultation with the California Department of Public Health. The fishery closure will remain in effect until the health agencies determine clams to be safe and recommend reopening the fishery.

State health agencies determined last spring that razor clams in Humboldt and Del Norte counties had unhealthy levels of domoic acid and recommended fishery closure in April 2016. The California Fish and Game Commission closed the fishery under emergency rules from April to October 2016 and extended the closure to Jan. 26, 2017.

Domoic acid is a potent neurotoxin produced by a naturally occurring marine algae. It causes illness and sometimes death in a variety of birds and marine mammals that consume affected organisms. At low levels, domoic acid exposure can cause nausea, diarrhea and dizziness in humans. At higher levels, it can cause persistent short-term memory loss, seizures and can in some cases be fatal.
