Fish Physiology

The course describes physiological mechanisms in fish. Topics covered include nerves and sense organs, endocrinology, circulation, respiration, iono- and osmoregulation, digestive system, reproduction, parr-smolt transformation and stress in fish.

Applicants from Nordic countries must have:

Generell studiekompetanse, samt følgende spesielle opptakskrav:

Matematikk R1 eller matematikk S1+S2 og i tillegg ett av følgende programfag:

• Matematikk (R1+R2)
• Fysikk (1+2)
• Kjemi (1+2)
• Biologi (1+2)
• Informasjonstekn (1+2)
• Geofag (1+2)
• Teknologi og forskningslære (1+2)

Application code: 9336 (Nordic applicants).All participants must have taken introductory level university courses, and achieved pass grades, in these subjects.

International applicants: Higher Education Entrance Qualification and certified language requirements in English. It is a requirement that students have  some prior knowledge of biology and ecology, chemistry and mathematics. A list of the requirements for the Higher Education Entrance Qualification in Norway can be found on the Norwegian Agency for Quality Assurance in Education website - nokut.no

After completing the course, the students should know:

• The structure, function and physiology of major organs in fish; the nervous system and sense organs, the respiratory and circulatory systems, the digestive system, the kidneys and the osmoregulatory system, the endocrine organs and the reproductive system.
• How environmental factors such as temperature, photoperiod and water quality affect the physiology of fish, with particular emphasis on coldwater species.
• Common causes of stress in fish kept in captivity, with special emphasis on cultured species (e.g. Atlantic salmon).
• How to read, discuss and present scientific data.

The students should be able to:

• Describe the structure and function of major organs in fish, and explain their physiology.
• Describe how environmental factors such as temperature, photoperiod and water quality affect the homeostasis of fish, with particular emphasis on physiological adaptations in coldwater species.
• Describe the General Adaptation Syndrome and how abiotic (environmental) and biotic (e.g. food, behavior) stressors may affect the homeostasis and physiology of fish.
• Write a scientific report based on laboratory work.

The course will give the students:

• A general background in fish physiology.
• An understanding of how important biotic and abiotic factors affect the physiology and welfare of cultured fish.
• Insights into how experimental studies on fish are performed.
• Skills in reading, discussing and presenting scientific data.

Language of instruction and examination

4 hours written exam (counts 2/3) and a laboratory report (counts 1/3). A graded scale of five marks from A to E for pass and F for fail.

There will be a re-sit examination for students that did not pass the previous ordinary examination. The re-sit examination is a written exam only.
