Disease prevention in shrimp aquaculture is a primary welfare intervention, as disease outbreaks cause significant suffering in affected animals while reducing the need for welfare-compromising treatments.
Shrimp disease prevention welfare recognizes that outbreaks cause mass suffering in affected animals — clinical disease signs including reduced feeding, abnormal swimming and rapid mortality represent acute welfare events at potentially enormous scale. Prevention through biosecurity, specific pathogen-free genetics, water quality management and early detection systems is far superior from both welfare and commercial perspectives to reactive treatment of established disease. The welfare case for investment in disease prevention infrastructure is clear: the alternative is periodic mass mortality events affecting millions of animals. As evidence for shrimp sentience strengthens, the ethical obligation to prevent such mass suffering events becomes more pressing.
