BI1009 - Nutrition and Welfare in Aquaculture


Lessons are not given in the academic year 2020/2021

Course content

Academic content
The course is divided into two parts and runs over one semester.
In the first part of the course you will give a basic introduction to the nutrients and nutritional needs of salmonids. In addition, an introduction will be given to methods for feed production and the challenges one has with raw material and ethics in production. The second part of the course will be a deeper introduction to fish welfare and fish health with special focus on the most important diseases, stress and operational parameters for welfare.

Learning outcome

Basic knowledge of salmon nutritional requirements, relationships between digestion and feed utilization and principles of feed production, extrusion, feed stability
Know the challenges in the feed raw materials situation and the challenges related to raw materials including price, availability, sustainability and anti-nutrients. The potential of "functional foods" will also be highlighted.
Know the most important diseases and parasite infections in fish farming, how they spread and how stress and contagious hygiene measures can be used to prevent spread of disease.
Know relevant legislsations, regulations and standards related to fish health and fish welfare.
The candidate can apply his/heer knowledge of salmon to understand and contribute to solving new biological and operational issues in aquaculture nutrition and animal welfare.
The candidate has the knowledge to find and apply relevant regulations, regulations and standards in nutrition and animal welfare.
The candidate is familiar with relevant biological methods and other professional tools for recognizing suboptimal farming conditions and contributing to solving the challenges.
The candidate can reflect on his/her own professional practice in the subject areas of the course and act as part of an interdisciplinary team with staff from the other important disciplines in aquaculture, preferably as responsible manager.
General competence:
The candidate can identify and initiate tasks and projects, and can plan and conduct experiments, normally as the leader of a professionally qualified team.
The candidate has broad insight into the environmental consequences and challenges of fish welfare in aquaculture and can put these in a broader perspective of economics and sustainability.
The candidate can communicate knowledge about salmon biology in farming and the influence of the marine environment to different target groups both in writing and orally in Norwegian and English, and can help to highlight aspects of the aquaculture profession's significance and consequences.
The candidate can, through sharing his knowledge and experience in academic discussions within the subject area and contribute to a continued sustainable operational and environmental development in aquaculture.
The candidate knows and can contribute to new thinking, innovation and the digitization of aquaculture based on the subject's subject areas.

Learning methods and activities

Teaching methods and activities
The teaching will largely be based on lectures, but there will also be simple laboratory exercises where short case studies will be done as physical characteristics of feed and behavior in salmon, as well as practical exercises in the recognition of diseases and characteristics. A compulsory excursion to the relevant company will be organized.

Compulsory assignments

  • Lab Work
  • Exercises
  • Excursion
