Farmed Tilapia Disease Prevention Welfare

Disease prevention in tilapia farming is a welfare priority, with streptococcosis and columnaris causing significant mortality and suffering globally.

Key Facts

Streptococcus agalactiae causes meningitis and eye disease in tilapia globally
Columnaris disease causes skin and gill lesions with rapid mortality
High water temperatures increase disease susceptibility in tilapia farms
Probiotics and organic acid supplements reduce enteric disease incidence
Vaccination against streptococcosis is available and effective in some production systems

Welfare Considerations

Disease in tilapia causes suffering through lesions, neurological symptoms, and death. Prevention through biosecurity, water quality management, and vaccination is far preferable to treatment. As tilapia welfare science advances, the welfare cost of disease is increasingly quantified and built into production standards.
