Farmed Tilapia Disease Immunity

Building disease immunity in farmed tilapia through vaccination, selective breeding, and management approaches.

Key Facts

Vaccination for Streptococcus and Aeromonas is now commercially available for tilapia
Immuno-stimulants including beta-glucans can enhance non-specific immune responses
Genetic selection for disease resistance is advanced in some tilapia breeding programs
Good nutrition including vitamin C is essential for maintaining immune competence
Stress reduction through optimized stocking and water quality improves disease resistance

Welfare Considerations

Disease immunity is a welfare benefit that reduces suffering from disease and the welfare costs of treatment. Building immunity through vaccination, genetics, and management prevents the mass mortality events and individual suffering associated with disease outbreaks in tilapia farming.

What You Can Do

Support aquaculture standards that require disease prevention through vaccination programs
Advocate for investment in tilapia disease resistance genetics
Choose certified tilapia from farms with documented immunity-building programs
