Southern Commercial Dungeness Crab Season Delayed in Ocean Waters North of Bodega Head Due to Public Health Hazard

California Department of Fish and Wildlife (CDFW) Director Charlton H. Bonham has delayed the opening of the commercial Dungeness crab fishery from Bodega Head, Sonoma County north to the Sonoma/Mendocino county line. The commercial Dungeness crab fishery south of this area will open as scheduled on Thursday, Nov. 15.

State health agencies determined that Dungeness crab in state waters from Bodega Head, Sonoma County north to the Sonoma/Mendocino county line have elevated levels of domoic acid and recommended a delay of the commercial fishery in this area.

The commercial delay includes ocean waters from the southern boundary of Bodega Head State Marine Reserve, Sonoma County (38° 18’ N. latitude) north to the Sonoma/Mendocino county line (38° 46.125’ N. latitude). Commercial take and/or possession of Dungeness crab is prohibited in these waters. North of the Sonoma/Mendocino county line, the Dungeness crab commercial season is not scheduled to open until Dec. 1. That opener is also subject to delay pending test results both for domoic acid as well as crab quality.

The area south of the southern boundary of the Bodega Head State Marine Reserve, Sonoma County to the California/Mexico border will open at 12:01 a.m. on Thursday, Nov. 15, 2018, to be preceded by an 18-hour gear setting period that would begin no earlier than 6:01 a.m. on Wednesday, Nov. 14.

This delay 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 the California Department of Public Health (CDPH), determines that domoic acid no longer poses a significant risk to public health and recommends opening the fishery in this region. CDFW will continue to coordinate with CDPH and OEHHA to test domoic acid levels in Dungeness crab to determine when the Dungeness crab commercial fishery in this area can safely be opened.

Once a positive determination is made to open the fishery, CDFW may provide the fleet a minimum of 72-hour advance notice announcing when trap gear can be set.

Additional information on the commercial Dungeness fishery can be found here.

The recreational fishery for Dungeness crab opened in most areas of the state on Nov. 3 under a health warning issued by CDPH for Dungeness crab caught in Sonoma County. The recreational fishery remains closed in state waters from Patrick’s Point in Humboldt County north due to elevated levels of domoic acid.

Domoic acid is a potent neurotoxin produced by a naturally occurring marine alga, whose levels can be increased under certain ocean conditions, and 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 death.

Commercial Rock Crab Fishery Continues to be Extended Northward to near the Mendocino/ Humboldt County Line

Following the recommendation of state health agencies, the California Department of Fish and Wildlife (CDFW) announced today that it will be extending the area open to commercial rock crab fishing from the Sonoma/Mendocino County line to near the Mendocino/Humboldt County line at 40° 00.00 ‘ N. Lat. This will open all commercial rock crab fishing from 40° 00.00 ‘ N. Lat. south to the California/Mexico border.

On Nov. 8, 2016, upon 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. Since that time, new authority established in the Fish and Game Code, section 5523, allowed the Director to open portions of the fishery upon the recommendation from the Director of OEHHA. The fishery was last modified in March 2018, when it was opened between Salt Point, Sonoma County and the Sonoma/Mendocino County line. 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. The recreational fishery for rock crab remains 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 north of the Mendocino/Humboldt County line to the California/Oregon border.

Closure of the commercial rock crab fishery north of 40° 00.00 ‘ N. Lat. near the Mendocino/Humboldt County line to the California/Oregon border 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 opened. CDFW will continue to coordinate with fishermen, CDPH, and OEHHA to test domoic acid levels in rock crab within the closure area of the coast. 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.

Opening of Commercial Rock Crab Fishery Extended to Sonoma/Mendocino County Line

Following the recommendation of state health agencies, the California Department of Fish and Wildlife (CDFW) announced today that it has extended the area open to commercial rock crab fishing from the Sonoma/Mendocino County line (38° 46.1′ N. Lat., near Gualala, Mendocino 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 on Nov. 8, 2016. On Jan.1, 2017, new authority established in the Fish and Game Code, section 5523, allowed the Director to continue the closure. Updated recommendations received from OEHHA have resulted in the Director opening parts of the commercial rock crab fishery north of the closure boundary near Pigeon Point. The fishery was last modified in January 2018 when the fishery was opened between Bodega Bay and Salt Point, Sonoma County. 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. The recreational fishery for rock crab remains 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 north of the Sonoma/Mendocino County line to the California/Oregon border.

Closure of the commercial rock crab fishery north of the Sonoma/Mendocino County line to the California/Oregon border 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 opened. CDFW will continue to coordinate with and the fishing community, CDPH and OEHHA to test domoic acid levels in rock crab within the closure area of the coast. 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.

Open Area of Commercial Rock Crab Fishery to be Extended to Salt Point, Sonoma County

Following the recommendation of state health agencies, the California Department of Fish and Wildlife (CDFW) announced today that it has extended the area open to commercial rock crab fishing from 38° 34′ N. Lat. (Salt Point, 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 on Nov. 8, 2016. On Jan.1, 2017, new authority established in the Fish and Game Code, section 5523, allowed the Director to continue the closure. Opportunistic sampling of rock crabs and continued high domoic acid levels have prevented the reopening of fishing grounds north of Bodega Bay, Sonoma County since Feb. 2017. 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. The recreational fishery for rock crab remains 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 north of Salt Point, Sonoma County to the California/Oregon border.

Closure of the commercial rock crab fishery north of Salt Point, Sonoma County to the California/Oregon border 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 opened.

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

Today the California Department of Fish and Wildlife (CDFW) Director Charlton H. Bonham lifted the commercial spiny lobster fishery closure on the south east side of Santa Cruz Island east of 119°40.000’ W. longitude, west of 119° 30.00’ W, and south 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 Assessment (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 Oct. 24, 2017, state health agencies determined that spiny lobster in waters around 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.

The commercial closure remains in effect in all state waters around the north east end of Santa Cruz Island east of 119°40.000’ W. longitude, west of 119° 30.00’ W, and north of 34°00.000’ N. latitude and south side of Anacapa Island east of 119°30.000’ W, west of 119°20.000’ W, and south of 34°00.000’ N latitude. State waters extend 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.
