The Oregon Department of Fish and Wildlife has closed razor clamming from Cascade Head north of Lincoln City to Seal Rock State Park because of high levels of domoic acid, a marine biotoxin.
Clamming remains open from the Washington border to Cascade Head and from just south of Seal Rock State Park to Cape Blanco, which is north of Port Orford on the southern Oregon coast.
Razor clam harvesting remains closed from Cape Blanco to the California border.
Crab, mussel, and bay clam harvesting are open statewide.
Domoic acid is produced by algae and originates in the ocean. The Oregon Department of Agriculture tests for shellfish toxins at least twice per month, as tides and weather permit. Reopening an area closed for biotoxins requires two consecutive tests with results below the closure limit.
