Aquaculture Lumpfish Welfare in Salmon Farms

Lumpfish are used as cleaner fish in salmon farms to control sea lice. As welfare concerns grow, better understanding of lumpfish needs is essential.

Key Facts

Lumpfish eat sea lice from salmon, reducing lice burden without chemical treatment
They are produced in hatcheries at scale for commercial salmon farming
Lumpfish welfare has been poorly understood and often overlooked
High mortality rates occur in sea cages from starvation, disease, and salmon aggression
Research programmes have improved understanding of lumpfish nutritional and environmental needs

Welfare Considerations

Lumpfish used as cleaner fish in salmon farming face significant welfare challenges. High mortality from inadequate feeding, disease, and predation by salmon represent welfare failures. As the welfare evidence base grows, production and husbandry standards are improving. Investment in lumpfish welfare is justified by both intrinsic welfare value and their effectiveness as lice control.
