Introduction to recirculation technology and hatchery production. Animal welfare, nutrition and laws and regulations related to hatchery production.

Second semester
Introduction to salmon biology and lifecycle part II.
Smoltification, transport, sea-pen farming and slaughter.
Handling and challenges with sea lice and other parasites.
Environmental impacts of salmon farming, escapees and genetic interactions with wild strains.
Laws and regulations.

Learning outcome

Basic biological knowledge of salmon biology and life cycle.
Basic knowledge of the industrial and technical operating modes and challenges in commercial farming.
Basic knowledge of how aquaculture can affect the marine environment.
Basic knowledge of the principles of sustainable aquaculture and that technology must be compatible with the nutritional and welfare needs of the fish.
Good knowledge of relevant legislation, regulations and standards related to fish farming processes, fish health, fish welfare, and environmental interactions of farming.
Master biological methods and professional tools for holding and handling salmon at all stages of life.
Must be able to apply their knowledge to understand and contribute to solutions of biological and operational issues.
Have knowledge on hos to find and apply relevant legislation, regulations, regulations and standards within the management areas of the Directorate of Fisheries, the Environment Directorate and the Norwegian Food Safety Authority.
Be able to reflect independently on academic issues and challenges and work independently in multidisciplinary teams.

Learning methods and activities

Practical exercises first term include handling and work with salmon eggs and start feeding and exercises with recirculation units. Practical exercises second term include smoltification and basal blood analysis. Exercises will be summarized in one report. This will be assessed and Count 20% of the final exam result.
Thematic excursions/projects at commercial aquaculture facilities such as hatcheries, sea-pens and slaughteries. The report will be evaluated as approved/not-approved.
