Welfare of Commercially Farmed Clams

Hard clams and other bivalve clams are farmed extensively in coastal waters; their welfare status is considered low risk given their neurological simplicity.

Key Facts

Clam farming improves water quality through filter feeding
Their nervous systems are extremely simple compared to fish or mammals
Clam harvest methods including mechanical dredging disturb coastal habitat
Farmed clams have minimal environmental footprint compared to fed aquaculture species
Clam farming can coexist with coastal ecosystem functions when managed appropriately

Welfare Considerations

Clam welfare risk is considered very low by most welfare scientists given their extremely simple nervous systems. Clams represent one of the most welfare-defensible seafood choices available, supporting both low welfare risk and sustainable coastal ecosystem functioning.

What You Can Do

Consider clams as a lower-welfare-risk seafood choice
Choose clams from farms using less destructive harvest methods
Support sustainable coastal clam aquaculture over wild dredged harvests
Share the welfare case for bivalves with others making ethical seafood choices
