Farmed Salmon Disease Parasite Welfare

Disease and parasite management in farmed salmon must balance treatment efficacy with the welfare costs of treatment procedures themselves.

Key Facts

Sea lice, amoebic gill disease, and pancreas disease are the three most significant welfare challenges
Each treatment intervention causes acute physiological stress that compounds existing disease burden
Preventive management that reduces disease incidence is preferable to reactive treatment
Fallowing periods between production cycles reduce pathogen buildup and disease pressure
Genetic selection for disease resistance eliminates welfare costs associated with both disease and treatment

Welfare Considerations

Salmon facing both disease and repeated treatment cycles experience cumulative welfare compromise from multiple sources simultaneously. Preventive strategies that reduce disease incidence minimize the total welfare burden across the production cycle.

What You Can Do

Support salmon from farms with documented disease prevention strategies
Advocate for mandatory disease management plans in salmon aquaculture licensing
Choose salmon from farms investing in genetic disease resistance and biological control
