Farmed Salmon Disease Challenge Welfare

Disease challenges including sea lice, amoebic gill disease, and ISA virus cause significant welfare compromise in farmed salmon operations.

Key Facts

Sea lice are the primary disease challenge in Atlantic salmon farming globally
Heavy lice burdens cause tissue damage, blood loss, and behavioral change in salmon
Amoebic gill disease is caused by Neoparamoeba perurans and causes respiratory distress
Freshwater treatments for lice cause acute osmoregulatory stress in treated fish
Integrated pest management combining biological, chemical, and mechanical approaches reduces treatment frequency

Welfare Considerations

Salmon with heavy disease burdens suffer from chronic tissue damage, respiratory compromise, and immunosuppression. Disease management strategies that minimize treatment stress are essential welfare priorities.

What You Can Do

Choose salmon from farms with certified integrated pest management programs
Support research into lower-stress disease treatment methods for farmed salmon
Advocate for welfare assessment of disease treatment protocols in aquaculture regulations
