How Wild Geoduck Is Harvested in Washington: Diver Fishery Guide
Washington's commercial wild geoduck fishery is unusual: geoduck live buried deep in subtidal sediment, so commercial harvest is performed underwater by divers rather than with a conventional clam dredge. This article focuses on the wild diver fishery and keeps it separate from geoduck aquaculture.
Where Wild Commercial Geoduck Are Harvested
Commercial wild geoduck harvest in Washington takes place on managed subtidal geoduck tracts. State and tribal managers use biological surveys and harvest planning to determine where commercial fishing occurs and how much can be harvested. This is different from intertidal geoduck farming, where juvenile clams are intentionally planted on aquaculture sites.
Why Divers Are Used
A geoduck's body remains buried in sediment while its long siphon reaches upward. Commercial divers locate geoduck on the seabed and use a water jet to loosen sediment around an individual clam. The clam is then removed by hand. The technique requires experience because the goal is to free a deeply buried animal without unnecessarily damaging it.

From the Seabed to a Live Product
Geoduck is commonly sold live, so the job does not end when the clam leaves the sediment. Careful handling, temperature control, and rapid movement through the supply chain are important to maintaining live quality.
How the Washington Fishery Is Managed
Washington's wild commercial geoduck fishery is managed through a state-tribal framework. Management includes biological surveys, designated harvest tracts, harvest limits and monitoring. Recovery of harvested beds can be slow, which makes long-term survey data and conservative management important.
We intentionally avoid claims such as a fixed number of pounds “per dive,” a universal extraction time for each clam, or a rule that only a specific age class is harvested. Those numbers vary or can misrepresent how the fishery is actually managed.

Wild Harvest Is Not the Same as Farming
Wild geoduck and farmed geoduck can both enter the live seafood market, but they come through different production systems. Wild geoduck are harvested from naturally occurring stocks under fishery management. Farmed geoduck are hatchery-produced, planted and grown on aquaculture sites before harvest.
Read our Geoduck Farming Guide for the aquaculture process, or our Geoduck Sustainability Guide for a broader discussion of management and environmental considerations.
Preparing Geoduck After Purchase
The siphon and body have different textures and are often prepared differently. Because this page is about harvesting rather than cooking, detailed cleaning, blanching, slicing, sashimi and cooked methods are covered in our How to Cook Geoduck guide.
Order Live Geoduck from Global Seafoods
A brief blanch to loosen the siphon skin is a preparation step, not full cooking. Cook raw seafood thoroughly; the general temperature recommendation is 145°F. Raw preparations carry additional risks.
