RAZOR CLAM LIMIT: Because of unusually abundant populations of harvestable razor clams WDFW has temporarily increased the daily bag limit to 20 clams per digger through the end of December 2021.

MARINE TOXIN UPDATE: Listed below are the most recent marine toxin levels, as announced by the Washington Department of Health (WDOH). As you can see, these samples are all below the action level for Amnesic Shellfish Poisoning (ASP) from Domoic Acid, Paralytic Shellfish Poison (PSP) and Diarrhetic Shellfish Poison (DSP). Recall, before a beach can be opened for the harvest of razor clams, WDOH protocol requires that all razor clam samples collected from that beach must test under the action level (20 ppm for domoic acid; 80 µg/100g for PSP; and 16 µg/100g for DSP).

Note that only razor clam meat tissue is tested.

These samples were all collected on 10/23/2021.

Long Beach (middle):

  • domoic acid =   4 ppm
  • PSP = none detected
  • DSP = none detected

Twin Harbors (middle):

  • domoic acid =   6 ppm
  • PSP = none detected
  • DSP = none detected

Copalis Area (middle)

  • domoic acid =   3 ppm
  • PSP = none detected
  • DSP = none detected

Mocrocks (middle)

  • domoic acid =   2 ppm
  • PSP = none detected
  • DSP = none detected
