Course content

This EVU course will give a broad introduction to RAS, but the main focus will be on technology and water quality. The course will introduce the water treatment system in a RAS and will broadly cover topics such as design, dimensioning, start-up, operation, monitoring and troubleshooting. We will emphasize the importance of good physical, chemical and microbial water quality for the health and welfare of the fish. The course will focus on Atlantic salmon, as this is the most relevant species in Norwegian aquaculture, but the course will also provide general insight that is valuable for other production species. The course will briefly touch upon sustainability aspects and future trends in RAS.
