Venus clams are farmed in intertidal and subtidal zones across southern Europe, with welfare considerations similar to other bivalves including harvest methods and the uncertain question of bivalve sentience.
Venus clam welfare considerations parallel those of other bivalves. The probability of conscious pain experience in clams is considered low based on current evidence, but cannot be completely excluded. Mechanical harvest causes physical damage and mortality to a proportion of animals harvested. Air exposure during transport and market holding may cause physiological stress. Environmental quality of aquaculture sites affects animal health and resilience - degraded water quality and disease pressure reduce the condition of farmed clams. From a precautionary welfare perspective and given the genuine scientific uncertainty, minimizing unnecessary harm during handling and processing is appropriate.
