Course content

The course focuses on the physiological processes in fish and their adaptations to environmental parameters. Lectures will cover general anatomy, respiration, circulation, osmoregulation and acid-base balance, smoltification, regulation of buoyancy, movement, sensory physiology, stress, gastrointestinal system and sexual maturation. Introductions will also be given to basal immunology. Practical lab studies include comparative anatomy and physiology of Atlantic salmon and at least one marine species available. Studies also include evaluation of organ histology and stress experiments.

Learning outcome


On completion of the course the student should have obtained valuable skills in fish anatomy and physiology including regulatory mechanisms.


The student should be able to design and perform tests of fish osmoregulatory capacity, establish sedation, perform blood sampling, and examine simple histological preparations from fish.

Learning methods and activities

Lectures: 30 hours with a combination of oral and online lectures. Distribution may vary from year to year.

Laboratory course: 2 mandatory exercises

Compulsory assignments

  • Approved histology laboratory
  • Approved dissection repport

Further on evaluation

The course consists of lab-reports that will be assessed pass or fail and a written exam (100%).

In case of fail or if you want to improve your grade the written exam can be retaken in both semesters, even the one without teaching. The written exam can be changed to an oral exam in the semester when the course is not taught.

Failing lab-reports will disqualify for exam and the candidate will have to follow the course the following year.
