Water quality in shrimp aquaculture ponds directly affects shrimp welfare through dissolved oxygen, ammonia, pH, and temperature parameters that must be managed within species-specific tolerance ranges.
Water quality is the fundamental welfare determinant for shrimp living in their aquatic environment. Poor water quality causes chronic physiological stress through hypoxia, ammonia toxicity, and osmotic disruption. Shrimp cannot escape poor water quality as terrestrial animals can move away from environmental stressors. Chronic stress from poor water quality impairs immune function leading to disease susceptibility and the suffering associated with disease. Well-managed water quality through adequate aeration, monitoring, and appropriate stocking density forms the foundation of shrimp welfare in aquaculture. Water quality standards should be incorporated into welfare certification as fundamental welfare criteria.
