Commercial Dungeness Crab Season to Open in Sonoma County

California Department of Fish and Wildlife (CDFW) Director Charlton H. Bonham issued a declaration to open the commercial Dungeness crab fishery from Bodega Head, Sonoma County north to the Sonoma/Mendocino county line.

The area 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) was closed due to elevated levels of domoic acid. Public health agencies have determined that domoic acid no longer poses a significant risk to public health in this area.

Under recent amendments to Section 5523 of the Fish and Game Code, the CDFW Director may provide a minimum of 72-hours’ notice before a gear setting period. Therefore, the Director has declared the fishery to open at 12:01 a.m. on Saturday, Dec. 8, 2018 to be preceded by an 18-hour gear setting period that would begin no earlier than 6:01 a.m. on Friday, Dec. 7, 2018.

No vessel may take crab within a delayed area during the closure period. In addition, any vessel that has landed crab from ocean waters outside of this delayed area is prohibited from taking, possessing onboard, or landing Dungeness crab in this area until Jan. 7, 2019 pursuant to Section 8279.1 of the Fish and Game Code.

The northern California commercial Dungeness crab fishery in Fish and Game Districts 6, 7, 8 and 9 (Mendocino, Humboldt and Del Norte counties) remains closed until 12:01 a.m. December 16, 2018 due to poor crab meat quality tests. If the next round of test results indicate good quality, the fishery will open and be preceded by a 64-hour gear setting period.

Commercial Dungeness Crab Season Delayed in Northern California

California Department of Fish and Wildlife (CDFW) Director Charlton H. Bonham issued a memo today delaying the northern California commercial Dungeness crab season due to poor crab meat quality test results. The delay includes Fish and Game Districts 6, 7, 8 and 9 (Mendocino, Humboldt and Del Norte counties).

The northern Dungeness crab fishery is delayed until 12:01 a.m. on Sunday, Dec.16, 2018 pending another round of test results tentatively scheduled for Dec. 1. If these results indicate good quality, the fishery will open and be preceded by a 64-hour gear setting period that would begin no earlier than 8:01 a.m. on Thursday, Dec. 13, 2018.

“Last season, the northern Dungeness crab fishery was delayed until Jan. 15, the latest a quality delay can be extended,” said CDFW Environmental Scientist Christy Juhasz. “Results from our recent test are very similar to last year indicating that this delay may be extended past Dec. 16.”

If the next round of quality tests remain low, the CDFW Director has the authority to delay the season an additional 15 days until Dec. 31. Under new legislation, CDFW can continue testing until Jan. 15.

Crab are evaluated to compare meat weight to total crab weight to determine whether they are ready for harvest under testing guidelines established by the Tri-State Dungeness Crab Committee. If results indicate poor crab quality, the CDFW director may delay the fishery under authority of Fish and Game Code Section 8276.2.

The southern Dungeness crab fishery opened on Nov. 15, except for the area 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) which was delayed due to domoic acid. Upon a recommendation from health agencies that domoic acid no longer poses a risk to public health, the CDFW director may provide a minimum 72-hours’ notice before the gear-setting period and avoid a gear set date that lands on state and federal holidays.

No vessel may take or land crab in an area closed for a meat quality delay (i.e., Fish and Game districts 6, 7, 8 and 9) or within an area closed for a domoic acid delay. In addition, any vessel that takes, possess onboard, or lands crab from ocean waters outside of a delayed area is prohibited from participating in the crab fishery in a delayed area for 30 days following the opening of those areas. This applies to any delayed areas in Oregon, Washington and California.

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.
