License Requirements A Shellfish/Seaweed License is required for harvesting razor clams and must be in the harvester's immediate possession and available for inspection during harvest and transport. Everyone claiming a limit must actively participate in the harvesting process, unless they possess a disability permit.Clam guns or shovel works, I have dug them by hand not the easiest way to go.Remember to keep your clams in seperate containers for each person digging.
