Crab Season Delayed….

Press release from the Department of Fish and Wildlife:

The California Fish and Game Commission today voted 3-0 in favor of an emergency rulemaking to prohibit recreational take and possession of Dungeness crab and all rock crab from ocean waters, including bays and estuaries, north of the Ventura/Santa Barbara county line. Closure of the fisheries shall remain in effect until the Director of the Office of Environmental Health Hazard Assessment (OEHHA), in consultation with the Director of the California Department of Public Health (CDPH), determines that domoic acid levels no longer pose a significant risk to public health and no longer recommends the fisheries be closed.
The Commission also directed the California Department of Fish and Wildlife (CDFW) to maintain a list of closed ocean waters of the state and update that list on Wednesday of each week by 1 p.m. It shall be the responsibility of any person prior to taking Dungeness crab to call the department’s hotline (831) 649-2883 or visit the department’s website to obtain the current status of any ocean water.

The recreational Dungeness crab season was scheduled to start Saturday, Nov. 7.
CDPH, in conjunction with CDFW, has been actively testing crabs since early September and results from the most recent tests showed that the health risk to humans is significant. CDPH issued a health advisoryon Tuesday. OEHHA followed that with a recommendation for delays and closures.

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.

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, epilepsy, and can in some cases be fatal.

Domoic acid is produced from some species of the marine diatom Pseudo-nitzschia. Currently, a massive toxic bloom ofPseudo-nitzschia has developed, significantly impacting marine life along California’s coast. Biologists tested crab from eight ports from Morro Bay to Crescent City, and determined that domoic acid levels are exceeding the State’s action level.

Algal blooms are common, but this one is particularly large and persistent. Warmer ocean water temperatures due to the El Niño event California is experiencing are likely the cause of the size and persistence of this bloom.

Commercial fisheries are also affected by domoic acid levels. CDFW has authority to delay or otherwise restrict commercial fisheries and is developing an emergency rulemaking under that authority. The commercial Dungeness crab season is currently scheduled to open Nov. 15.




  • Well thats a bummer. The article makes it sound like they might be testing weekly. I doubt that. Although, knowing how much money crab season sport and commercial generates, maybe they will test weekly. I recently wiped out crab I canned in expectation of fresh dungies. I might start getting the shakes. Better than the trots I guess.

  • The most complete report I’ve seen anywhere! Including future update information. Thanks!!

  • I wonder if a bull is using a sheet here….

    Has the Fukushima plume combined with rod storage fire in Nevada enough to cover tracks?

    The entire West Coast has seen die offs….

    Are local fishermen getting sick?

    Would like to hear..


    • I’ve been catching and eating salmon, lingcod, and rockfish from Trinidad waters all summer. We always quit clamming every year in the summer because of the toxins. That’s routine every year though. This is just an odd year because of the warmer water, and has extended later than usual, or so they say. The warmer water is because of the exceptionally strong El Nino affect this year.
