Aquaculture Welfare

Farmed Shrimp Water Quality and Welfare

Water quality management in shrimp ponds is the primary determinant of disease risk, stress, and mortality in farmed shrimp.

Key Facts

Dissolved oxygen, pH, and ammonia are the key water quality parameters in shrimp farming
Hypoxia is the most immediate welfare emergency in shrimp aquaculture
Early morning oxygen crashes before aeration startup are a common mortality cause
Recirculating aquaculture systems allow precise water quality control

Welfare Considerations

Shrimp experiencing hypoxia show agitation followed by loss of coordination and mortality in severe cases. Chronic suboptimal water quality creates ongoing physiological stress that impairs immune function and increases disease susceptibility. The precautionary approach to shrimp welfare suggests that preventing these conditions is important even while uncertainty remains about the full extent of shrimp suffering.

What You Can Do

Support shrimp products certified to good aquaculture practice standards
Advocate for water quality monitoring requirements in shrimp certification
Support development of closed-system shrimp farming with better water control
Reduce shrimp consumption or choose alternatives when welfare standards are unclear
