Geoduck: Welfare in Pacific NW Aquaculture

Key Welfare Facts

Geoducks are the largest burrowing clams, highly valued for siphon meat in Asian markets.
As bivalve molluscs, classical sentience-based welfare arguments have limited direct application.
Harvest using high-pressure water jets to dislodge burrowed clams causes disruption of their natural habitat.
Aquaculture geoducks are grown in intertidal plots using PVC tubes to prevent burrowing predators.
The long production cycle of 5-7 years creates extended animal husbandry commitments and welfare exposure.
Ecosystem welfare impacts from aquaculture plots on wild intertidal communities require ongoing monitoring.

Welfare Assessment

Geoduck welfare science applies the precautionary principle to a species where sentience evidence is uncertain. Supporting environmentally responsible geoduck aquaculture that minimises ecosystem welfare impacts and handles individual animals appropriately reflects reasonable precautionary welfare application.

What You Can Do

Apply precautionary welfare consideration when handling and harvesting geoduck clams
Support geoduck aquaculture operations with documented environmental impact monitoring
Advocate for ecosystem welfare assessment requirements in geoduck aquaculture licensing
Choose aquaculture geoduck over wild-harvested where traceability and standards are better
