About this course
Content
Introduction to salmon biology and lifecycle part II. Water quality. Salmonid nutrition. Smoltification, fish welfare and stress, transport, sea-pen farming and slaughter. Introduction to marine technology with hydrostatics and stability of relevance for aquaculture. Handling and challenges with sea lice and other parasites. Environmental impacts of salmon farming - sustainability.
Learning outcomes
Knowledge:
- Practical knowledge of animal husbandry, water quality needs and follow-up of a life cycle of salmon from the fry stage to seawater-tolerant fish and thus a good understanding of professional ethics throughout a semester.
- Scientific methodology - sampling of fish as well as training in the conduct of laboratory analyzes to determine the physiological status of the fish.
- Basic knowledge of how aquaculture can affect the marine environment.
- Basic knowledge of sustainable aquaculture and that technology must be compatible with the nutritional and welfare needs of the fish.
- Basic introduction to nutrients, nutritional needs of salmonids and new feed resources.
- Understand and apply marine stability terminology and language, orally and in writing in a basic way.
- Calculate buoyancy, buoyancy distribution, trim, load capacity and initial stability of floating devices - understand the physics behind static and dynamic stability in intact state.
- Basic knowledge of the industrial and technical methods of operation and challenges in commercial farming.
- Important knowledge about fish health, fish welfare, animal husbandry, ethics, and environmental interactions in aquaculture.
- Knowledge of the UN's sustainability goals and assessment of the aquaculture industry in relation to these goals.
Skills:
- Master biological methods and professional tools for keeping and handling salmon in all life stages.
- Must be able to apply their knowledge to understand and contribute to solutions of biological and operational problems.
- Perform simple laboratory experiments in an efficient manner within requirements for HSE (health, safety and environment), as well as analyze and evaluate results from these.
- Be able to reflect independently on professional issues and challenges and work independently in interdisciplinary teams.
Teaching methods
Lectures and exercises
Practical- and digital exercises: Include smoltification, stress and basal blood analysis. Stability lab that includes various stability criteria in the test tanks. Exercises will be summarized in reports and will be assessed as 30% of the total grade.
Thematic excursions/projects at commercial aquaculture facilities such as hatcheries, sea-pens and slaughteries. The reports from the excursions will be evaluated as approved/not approved.
