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 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.

More of Commercial Dungeness Crab Fishery to Open Dec. 3; Some Areas Will Remain Closed

An approximately 50-mile portion of the commercial Dungeness crab fishery between Point Reyes, Marin County and near Salt Point, Sonoma County that has been closed due to elevated domoic acid levels will open on Dec. 3 at the recommendation of state health agencies, the California Department of Fish and Wildlife (CDFW) announced today. However, the fishery will remain closed north of Salt Point to the Humboldt Bay entrance. The closed portions of the coast may open once testing by state agencies shows that the area is safe with regard to domoic acid levels.

On Dec. 3 at 12:01 a.m., the commercial Dungeness crab season will open from Point Reyes (38° 00’ N. lat.) to near Salt Point (38° 34.5’N. Lat.).  The opener will be preceded by an 18-hour pre-soak period commencing at 6 a.m. on Dec. 2.  The area between Salt Point and the north jetty at the Humboldt Bay entrance south will remain closed until the CDFW Director receives a recommendation from the state health agencies that levels of domoic acid – a naturally occurring toxin – do not pose a public health risk. Last fall and winter, domoic acid along the West Coast interrupted Dungeness and rock crab fisheries from Santa Barbara to the Oregon state line.

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 keep the commercial Dungeness crab fishery closed north of Point Reyes (38° 00’ N. lat.) and to close the commercial rock crab fishery north of Pigeon Point (37° 11’ N. lat.). 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 in the viscera, or guts. Because of this, on Nov. 8, OEHHA in consultation with the California Department of Public Health (CDPH) recommended to CDFW to close or delay the start of the commercial Dungeness crab season north of Point Reyes and close the commercial rock crab fishery north of Pigeon Point. On November 23, OEHHA, in consultation with CDPH, recommended that CDFW open the commercial fishery from the north jetty at the Humboldt Bay entrance to the California/Oregon state line at its normal opening date of Dec. 1, and is now recommending the commercial fishery be opened from Point Reyes to near Salt Point.

The recreational season for Dungeness crab opened on Nov. 5 and remains open with a warning from CDPH to recreational anglers to avoid consuming the internal organs of Dungeness crab caught between Salt Point and the north jetty at the Humboldt Bay entrance.

Closure of the above-referenced commercial fisheries 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 fisheries be open, and the Director of CDFW provides notification to the commercial fisheries. Recreational fisheries will remain open under a warning to anglers not to eat the guts of crab caught in the affected areas.

CDFW will continue to coordinate with CDPH and OEHHA to test domoic acid levels in crab along the coast to determine when the fisheries can safely be opened. CDPH, in conjunction with CDFW, has been actively testing crabs since early September and results from the most recent tests showed that select crabs from the closed areas had elevated levels of domoic acid 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.

More of Commercial Dungeness Crab Fishery to Open; Some Areas Will Remain Closed

A roughly 120-mile portion of the commercial Dungeness crab fishery in northern California that was scheduled to open Dec. 1 will remain closed at the recommendation of state health agencies, the California Department of Fish and Wildlife (CDFW) announced today. But the fishery will open Dec. 1 north of Humboldt Bay to the Oregon state line and remains open from Point Reyes southward. The closed portions of the coast may open once testing by state agencies shows that the area is safe with regard to domoic acid levels.

On Dec. 1, commercial Dungeness crab season will open as scheduled from the north jetty at the Humboldt Bay entrance (40° 46.15’ N. lat.) north to the Oregon/California state line (District 6).  The opener will be preceded by a 64 hour pre-soak period commencing at 8 a.m. on Nov. 28.  The area between the north jetty at the Humboldt Bay entrance south to Point Reyes (38° 00’ N. lat.) in Marin County will remain closed until the CDFW Director receives a recommendation from the state health agencies that levels of domoic acid – a naturally occurring toxin – do not pose a public health risk. Last fall and winter, domoic acid along the West Coast interrupted Dungeness and rock crab fisheries from Santa Barbara to the Oregon state line.

Under an emergency rulemaking, the area between Point Reyes and the Mendocino/Sonoma county line has been closed since Nov. 15 and remains closed due to elevated domoic acid levels, which can sicken people who consume crab.

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 keep the commercial Dungeness crab fishery closed north of Point Reyes (38° 00’ N. lat.) and to close the commercial rock crab fishery north of Pigeon Point (37° 11’ N. lat.). 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 in the viscera. Because of this, on Nov. 8, OEHHA in consultation with the California Department of Public Health (CDPH) recommended to CDFW to close or delay the start of the commercial Dungeness crab season north of Point Reyes and close the commercial rock crab fishery north of Pigeon Point.

The recreational season for Dungeness crab opened on Nov. 5 and remains open with a warning from CDPH to recreational anglers to avoid consuming the viscera of Dungeness crab caught north of Point Reyes.

Closure of the above-referenced commercial fisheries 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 fisheries be open, and the Director of CDFW provides notification to the commercial fisheries. Recreational fisheries will remain open under a warning to anglers not to eat the viscera of crab caught in the affected areas.

CDFW will continue to coordinate with CDPH and OEHHA to test domoic acid levels in crab along the coast to determine when the fisheries can safely be opened. CDPH, in conjunction with CDFW, has been actively testing crabs since early September and results from the most recent tests showed that select crabs from the closed areas had elevated levels of domoic acid 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.

The states of Washington and Oregon have acted to delay their respective 2016 Dungeness crab seasons. For more information:
