About this course

This subject provides an introduction to fish health in farmed salmon with emphasis on the most important bacterial, viral and parasitic infections/infestations in salmonids. In addition, an introduction to the most important production-related diseases is given. The teaching will focus on the normal physiological status of the fish and how various factors linked to the environment, stress and the presence of various pathogens in the environment interact to cause disease to occur. The focus will be on the most important disease-causing bacteria, viruses and parasites, including methods for diagnostics, prevention and control (biosecurity) of disease.
