Deep concerns over cleaner fish strategy

New research suggests that cleaner fish are nine times less effective at removing sea lice from salmon in pens surrounded by lice skirts, possibly due to the increased depth the salmon swim at in such pens.
In an experiment at the Centre for Aquaculture Competence, a full-scale research salmon farm in Norway, scientists tested if lice consumption by wild-caught corkwing wrasse changed when they were used together with a range of other measures to prevent lice.
