Oregon shellfish regulations

January 5, 2024

Oregon has over 360 miles of coastline -- that's a big sandbox in which to take the family clamming and crabbing. They're open throughout the year and are suitable for everyone in the family. It's fun, it's easy, it's delicious.

The following summarizes the regulations for marine shellfish and invertebrates in the Pacific Ocean, coastal bays and beaches. For complete information, Sport Fishing Regulations books may be obtained at ODFW offices and wherever licenses are sold.

LICENSE REQUIREMENTS: Everyone 12 years and older needs a license to harvest shellfish. Licenses are available for a day or a full-year and can be purchased online, from an ODFW license agents or at an ODFW office that sells licenses.

OPEN SEASON: Entire year and at all hours (exceptions are listed under “Harvest methods and restrictions” in the table below) and except when any state agency has issued a public health advisory.

HEALTH ADVISORIES: Crabbing and clamming occasionally can be closed due to elevated levels of biotoxins or other health issues. ODFW and the Oregon Department of Agriculture (ODA)‌ monitor shellfish safety on a regular basis to ensure shellfish are safe to eat. Always contact ODA by phone 800-448-2474 or check their website before you go to learn about any current health advisories.

OPEN AREAS: All areas are open except Marine Gardens, Marine Reserves, Research Reserves, Habitat Refuges, and Shellfish Preserves. These areas have signs indicating their locations and are listed and mapped in the Sport Fishing Regulations book.


  • Waste fish, shellfish or marine invertebrates.
  • Use chemicals to take fish, shellfish or marine invertebrates.
  • Assist in the harvest of another person’s catch except under an Oregon Disabilities Hunting and Fishing Permit.
  • Sell any sport caught fish or shellfish, except the skeletal remains of nongame marine fish.
