As thousands of recreational anglers await the start of the statewide sport season for Dungeness crab on Saturday, Nov. 2, the California Department of Public Health (CDPH) is advising anglers not to consume the viscera of crab caught in two coastal areas due to the presence of domoic acid.
In a health advisory issued today, CDPH advises recreational anglers not to consume the viscera (guts) of Dungeness crab caught from Shelter Cove in Humboldt County (40° 01.00′ N. Lat.) south to Point Arena in Mendocino County (38° 57.50′ N. Lat.) and from Point Reyes in Marin County (38 ° 00.00′ N. Lat.) south to Pillar Point in San Mateo County (37° 30.00′ N. Lat.).
Domoic acid is a potent neurotoxin produced by a naturally occurring marine diatom (algae). Under certain ocean conditions large blooms of these diatoms occur and then accumulate in Dungeness crab. 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. Please remember to eviscerate any crab caught in these regions prior to cooking. This reduces the risk of domoic acid poisoning. Check the CDPH Domoic Acid webpage for the latest crab test results.
Beginning at 12:01 a.m. on Saturday, Nov. 2, recreational crabbers are limited to a daily bag and possession limit of 10 crabs that are at least 5 ¾ inches in width as measured by the shortest distance through the body from edge of shell to edge of shell directly in front of and excluding the points (lateral spines).
Dungeness crab may be caught using hoop nets, crab traps, crab loop traps (crab snares) or skin and scuba divers may take them by the use of the hands only.Crab trap buoys must display the owner’s “GO ID” number as assigned by the Automated License Data System and the trap must contain at least one destruct device. When using another person’s trap, written permission, including permission transmitted electronically (i.e. email or text), from the owner of the trap must contain the GO ID number that matches the GO ID on the buoy and must be in the operator’s possession in order to operate the trap.
Minimizing the risk of whale and turtle entanglements remains a top priority of the California Department of Fish and Wildlife (CDFW). CDFW recently requested the Fish and Game Commission consider regulations to reduce the risk of entanglements in recreational Dungeness crab fishing gear. The Commission’s Marine Resources Committee will discuss and consider possible management recommendations at its meeting on Nov. 5 in Sacramento.
CDFW strongly encourages anglers to follow the Best Fishing Practices Guide developed by the California Dungeness Crab Fishing Gear Working Group. Voluntary actions anglers can employ include keeping the line between the pot and main buoy taught and vertical, reducing the amount of vertical line at the surface, avoiding setting gear in the vicinity of whales and turtles, and marking gear consistent with regulations.
