About the course
Theoretical subject.
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.
Objectives of the course
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.
