Clam farming is among the most environmentally benign forms of aquaculture, with questions about bivalve sentience informing a cautious ethical assessment of welfare implications.
Farmed clam welfare sits at the boundary of current scientific knowledge about invertebrate sentience. The absence of a centralized brain and complex nervous system suggests limited capacity for conscious suffering, though some sensory responsiveness exists. Clam farming represents a relatively defensible protein source from an animal welfare perspective compared to vertebrate aquaculture, while also providing significant environmental benefits. Continued research into bivalve nociception will refine this ethical assessment.
