New research has revealed that lumpfish exposed to live prey and frozen sea lice prior to transfer to marine sites perform better as cleaner fish once stocked in salmon pens.
Extreme weather events and changing ocean conditions are creating unpredictable outcomes for aquaculture. One area where research is offering some insight into what to expect, though, is the increasing incidences of disease.
With sea lice an increasingly tough problem for salmon farmers to treat, new research suggests that managing water temperature might be more effective than blitzing the parasites with more chemicals
Eirik Sigstadstø, R&D director at the Norwegian Research Fund (FHF), has high hopes for next week’s sea louse control conference in Trondheim, in which the use of lumpfish and wrasse are set to be high on the agenda.
