Use of lumpfish for sea-lice control in salmon farming: challenges and opportunities [PDF]

, 2017
Efficient sea-lice control remains one of the most important challenges for the salmon farming industry. The use of wrasse (Labridae) as cleaner fish offers an alternative to medicines for sea-lice control, but wrasse tend to become inactive in winter ...
