Clams can be dug by hand or hand-operated fork, pick, rake, or shovel. Each digger must use a separate container to retain catch. Digging equipment may be shared. Clam holes must be refilled. To reduce clam mortality, please push any undersized clams into the refilled hole. Caution: Always check the local biotoxin status before harvesting via the biotoxin hotline (1-800-562-5632) or

Description and Range

Physical description

Native littleneck clams have an oval to round shape and they grow up to 3½ inches long. The shell exterior exhibits concentric rings with radiating lines that form a lattice pattern. They may be cream or grey colored and may display a variety of different patterns. The anterior (lower) side of the hinge of the native littleneck clam typically has a pronounced ridge, whereas the same location on the Manila clam is indented.

Native littleneck clams are buried 4 to 6 inches deep in cobble, gravel, sand, or mud substrate and they normally occur in the mid-intertidal zone.

Geographic range

Native littleneck clams can be found from the Aleutian Islands, AK south to Baja California Sur.

This species is identified as a Priority Species under WDFW's Priority Habitat and Species Program. Priority species require protective measures for their survival due to their population status, sensitivity to habitat alteration, and/or recreational, commercial, or tribal importance. The PHS program is the agency's main means of sharing fish and wildlife information with local governments, landowners, and others who use it to protect priority habitats for land use planning.
