Reduction of fouling, risk of infection and outbreaks of disease on marine fish farming

Project Department: Uni Research Environment (groups: Molecular Ecology, SAM-Marin - marine biology) period: 01.03.17 - 01.03.20

About the project

R & D projects funded by Regional Research Funds in Norway (RFF Vest, innovation project)


Fouling in aquaculture represent a significant challenge due to extra load on nets and structures, reduced water exchange through the cage-net and decreased efficiency of cleaner fish used to control salmon lice. Methods for control fouling include in situ cleaning with use of high-pressure washers on the net as a common method of biofouling management. Frequent flushing of the nets during a production will release significant amount of organic material to the environment, resulting in both increased benthic deposition and water borne fragments to the surroundings. Different fouling organisms represent potential reservoirs for fish pathogens, hence biofouling management may cause spread of disease agents and increased risk of infections in the fish farm.



  • Effective methods for detection of pathogens in fouling
  • New and improved antifouling agents in net impregnation
  • Optimising operational routines on aquaculture facilities (handling of nets to reduce risk of infection)
