Results show generally good fish health and no detection of notifiable diseases, though opportunistic and gill-associated bacteria remain widespread. A novel poxvirus, cod gill poxvirus, was detected in one farm during the study period.
Experimental trials demonstrated that cod can act as an asymptomatic carrier of infectious pancreas necrosis virus and transmit the virus to other species, highlighting the need for strengthened multi-species biosecurity. The project provides a data-driven foundation for improved risk assessment of spread of infectious diseases and sustainable growth of cod aquaculture.
