Oysterville Sea Farms

Explore the cleanest estuary in the USA: Willapa Bay

Tour Duration: 90 Minutes | Route: Deck → Beds → Cannery → Shucking Station

1. The Deck: History & Origins 15 Min

A Hub of the Mid-1800s

Founded after Chief Nahcati introduced oysters to founders in the mid-1800s. Oysterville was once the county seat, a bustling hub with its own college and hotels.

  • 1880/1893: Economic shifts saw the railroad bypass the town and the county seat move to South Bend.
  • The Cannery: The last physical link to the early industry (1930s-1967).

Biology 101

Oysters are bivalve mollusks. They lack a central nervous system and use gills to filter natural algae from the water.

2. Walking the Beds: Foraging & Ecology 20 Min

Intertidal Garden

Native plants absorb salt and minerals directly from the coastal environment.

  • Sea Beans & Sea Asparagus: Salty and crisp.
  • Sea Fennel: Citrusy and herbaceous.

Eelgrass

Eelgrass: The "Blue Carbon" Hero

Eelgrass stabilizes sediment and stores carbon more effectively than land forests. Oysters filter the water to keep it clear for eelgrass growth.

3. The Method Chain: How Oysters are Raised 10 Min

Farming is a disciplined chain of cause and effect. Our methods prioritize low disturbance and high quality.

Step 1: The Nursery (FLUPSYs)

Before they hit the bay, juvenile "spat" grow in Floating Upwellers (FLUPSYs). These systems use a paddlewheel to force a constant stream of nutrient-rich water through the oysters.

  • 100% Natural: No artificial food; only local algae.
  • Fast & Safe: Accelerates growth to move oysters past their most vulnerable stage.

Step 2: Traditional On-Bottom Harvesting

Hand Harvest: Oysters are picked by hand at low tide. This method has zero mechanical disturbance to the bay floor and allows for selective quality control.

Comparison: Unlike mechanical dredging, hand harvesting preserves the natural substrate and ecosystem balance.

Step 3: Off-Bottom Bag Culture

Oysters are placed in mesh bags on racks above the sediment. This protects them from predators and burrowing shrimp, while tidal wave action naturally tumbles the shells to create a deep, beautiful "cup."

The Result: 100% Natural Feeding

Regardless of the method, Oysterville oysters rely entirely on the natural algae of Willapa Bay. By filtering 50 gallons a day, they leave the water cleaner than they found it.

4. The Cannery & Shucking 40 Min

Post-Harvest Journey

Oysters are culled (sorted) and tumbled to toughen the shell before being packaged alive and fresh for market.

Willapa Bay: Produces roughly 25% of all U.S. farmed oysters thanks to massive 8–10 foot tidal exchange.

Shucking Pro-Tips

Safety: Always use a glove or towel.

  1. Start opposite the hinge, cupped side down.
  2. Wiggle knife to find the entry.
  3. Cut the adductor muscle along the bottom.
  4. Scrape loose and enjoy!
