UK researchers received funding to boost a key vaccination to protect ballan wrasse, used widely as a cleaner fish in salmon farms. The project could unlock greater use of the fish to control sea lice in the sector.

A consortium made up of salmon producer Mowi, the University of Stirling’s Institute of Aquaculture, Otter Ferry Seafish, Ceva Ridgeway Biologicals and the Sustainable Aquaculture Innovation Centre (SAIC) will explore how to best deliver vaccinations against Aeromonas salmonicida, a bacterium that can cause fatal outbreaks of disease in cleaner fish.
