Intensive Aquaculture Disease Prevention

Disease prevention in intensive aquaculture through biosecurity, vaccination, and water quality management reduces welfare harms to billions of fish annually while also reducing antibiotic use and production losses.

Key Facts

Salmon lice vaccines in development could eliminate chemical treatment welfare costs if successful
Infectious salmon anemia vaccination has dramatically reduced IHN mortality in salmon farming
Biosecurity protocols including site fallowing break disease cycles in intensive fish farming
Water recirculation systems that control pathogen exposure reduce disease incidence substantially
Prophylactic antibiotic use masks disease problems that improve husbandry would prevent

Welfare Considerations

Disease prevention in aquaculture is a welfare investment that pays dividends in reduced suffering for billions of fish. Every disease outbreak prevented is billions of individual fish spared from the distress of illness. Vaccination programs that eliminate diseases requiring chemical treatments replace a treatment welfare cost with a welfare-neutral preventive. The alignment between disease prevention, reduced antibiotic use, and welfare improvement makes investment in biosecurity and vaccination one of the most clearly welfare-positive management choices in aquaculture.
