Ensuring Safe and Legal Shellfish Harvest

Familiarize Yourself with Regulations and Seasons (Avoid Legal Issues)

Understanding the regulations and seasonal variations is crucial to avoid legal penalties. Each beach has specific rules regarding size and bag limits for clams, mussels, and oysters. Visit the Washington Department of Fish and Wildlife (WDFW) website or contact their customer service desk at (360) 902-2700 to confirm the open seasons for harvesting. Additionally, beach-specific seasons are available on Any sudden rule changes are promptly updated on the WDFW website or through the toll-free WDFW Shellfish Rule Change Hotline at (866) 880-5431.

Stay Informed about Pollution Closures (Prioritize Health)

Ensuring the safety of harvested shellfish involves checking for pollution closures and advisories. This information can be accessed through the Shellfish Safety Information resource. For detailed updates and insights into beach conditions, refer to the Washington Department of Health (DOH) website at or contact them directly at (360) 236-3330. Additionally, local health department numbers are available in government directories.

Monitor Marine Biotoxin Closures and Vibrio Warnings (Protect Against Health Risks)

Being vigilant about marine biotoxin closures and Vibrio warnings is vital for safeguarding health. Emergency closures due to Shellfish Poisoning (PSP/ASP/DSP) or Vibrio bacteria can occur suddenly. To verify the safety of shellfish harvesting areas on the intended day, visit the DOH website at, call (360) 236-3330, or dial the Shellfish Safety toll-free Hotline at (800) 562-5632.

Understanding that different state agencies oversee distinct aspects of recreational shellfish harvest closures is essential. The Washington Department of Fish and Wildlife (WDFW) manages conservation closures and seasonal adjustments to preserve intertidal shellfish populations. Conversely, the Washington Department of Health (DOH) is responsible for closures related to human health concerns, such as Paralytic Shellfish Poisoning (PSP)/Amnesic Shellfish Poisoning (ASP)/Diarrhetic Shellfish Poisoning (DSP), Vibrio bacteria, or pollution. These closures and advisories are detailed in the Shellfish Safety section on Shellfish Safety Information, encompassing both permanent WDFW/DOH closures and periodic DOH harvest advisories.

Clam, Mussel, and Oyster Shellfish Beach Status

To ensure a safe and legal shellfish harvest, it's vital to understand the key indicators associated with beach status:

WDFW Season

  • Open (✓): Indicates that the harvesting season is open, making it safe and legal to gather shellfish.
  • Closed (X): Denotes the closure of the harvesting season, rendering any harvest illegal. This closure may be due to conservation measures or seasonal adjustments by the Washington Department of Fish and Wildlife (WDFW) to protect shellfish populations.

DOH Status

  • Open (✓): Signifies that the beach meets health standards, allowing for safe and legal harvesting.
  • Closed (X): Indicates a closure due to unsafe conditions, making harvesting illegal. This closure may result from potentially life-threatening environmental factors such as pollution or biotoxins, monitored by the Washington Department of Health (DOH).

Harvest Status

  • Safe & Legal: Occurs when both WDFW and DOH statuses are open (✓), ensuring that harvesting is both safe and legal.
  • Illegal: Arises when the WDFW season is closed (X) while the DOH status remains open (✓), making any harvest illegal.
  • Not Safe: Describes situations where the DOH status is closed (X), indicating unsafe conditions for harvesting, regardless of the WDFW season status.
  • Not Safe & Illegal: Reflects closures where both WDFW and DOH statuses are closed (X), signaling both safety concerns and illegal harvesting.

Obtaining Required Licenses for Shellfish Harvest

To engage in shellfish harvesting, including seaweed, certain licenses and endorsements are mandatory to ensure compliance with regulations:

Shellfish/Seaweed License

  • Requirement: A Combination or Shellfish/Seaweed License is obligatory for all shellfish (excluding crawfish) and seaweed harvesting activities.
  • Purpose: This license ensures that harvesters have legal authorization to gather shellfish and seaweed from designated areas.

Dungeness Crab Fishing Endorsement

  • Requirement: Individuals intending to fish for Dungeness crab in Puget Sound must possess a catch record card and endorsement.
  • Purpose: This endorsement is necessary to regulate and monitor Dungeness crab fishing activities specifically in Puget Sound.

Possession Limits

Daily Limit and Storage Requirements

  • Daily Limit: Harvesters are allowed one daily limit of shellfish in fresh form. Any additional shellfish in possession must be frozen or processed to clearly distinguish them from the day's limit.
  • Purpose: This regulation aims to ensure responsible harvesting practices and prevent overexploitation of shellfish resources.

Designated Harvesters for Persons with Disabilities

  • Requirement: Individuals with disabilities must possess a designated harvester companion card issued by WDFW if assisted by another harvester. Both the harvester and the person with a disability must be licensed.
  • Supervision: The designated harvester assisting a person with a disability must remain within direct line of sight of the licensee or within ¼ mile if visibility is not feasible.
  • Purpose: This provision facilitates equitable access to shellfish harvesting activities for individuals with disabilities while maintaining compliance with licensing regulations.

Tideland Ownership Regulations

  • Private Ownership: Most beaches in Puget Sound, Hood Canal, Grays Harbor, and Willapa Bay are privately owned. Harvesting shellfish or seaweed from private beaches requires permission from the owner or lessee.
  • Exemptions: Private tideland owners, lessees, and their immediate family members are exempt from personal use daily limits when harvesting clams, oysters, and mussels from their own tidelands.
  • Commercial Harvest: Harvesting shellfish in excess of daily limits from private beaches for presumed commercial purposes necessitates a shellfish certification from the Department of Health.
  • Purpose: These regulations aim to protect private property rights while promoting sustainable shellfish harvesting practices and preventing overharvesting.
