NBIK14005U The Biology of Fish
- MSc Programme in Biology
- MSc Programme in Biology with a minor subject
The course aims to provide the student with detailed knowledge of different aspects of fish physiology. The course will provide an understanding of the respiratory and circulatory system of these animals, as well as how oxygen is transported. In addition effect of - and physiological adaptation to - a variety of environmental factors, i.e. hypoxia, salinity, CO2, pH and temperature, will be described. The course will also provide understanding of the physiology affiliated with fish swimming as well as feeding and digestion.
The course consists of a mixture of traditional textbook lectures and examples describing the different environments, as well as case-studies.
Demonstrations will illustrate the anatomy of fish and different techniques. Experimental hands-on research projects, each with 2 – 3 students, will carry out independent studies of i.e. oxygen consumption and hearth rate in response to hypoxia, how does a fish swim and how much it cost and hearth physiology.
During the course articles are presented by the students and the teachers. In addition, the students functions as opponents to the presented articles.
A student who has met the objectives of the course will be able to:
- Explain and describe the respiratory and circulatory systems, and oxygen transport in fish and how these transport oxygen.
- Describe feeding and digestion.
- Explain and describe the possible effects of hypoxia on metabolic rate.
- Describe oxygen consumption of exercising fish.
- Explain how fish osmoregulate.
- Describe the differences between aquatic air and water breathers.
- Describe and explain the effect of temperature on metabolism.
- Describe the anatomy of fish.
- Plan and carry out an experiment, analyze the data and use the results in a report.
The student can describe and reflect on a given research topic. The student is able to identify methodological problems and can place them in a comprehensive experimental overview.
The student will be able to handle some standard equipment for marine biological research and use experimental methods. The student can analyze and explain experimental results and put them into a scientific context.
The student will gain experience and competence working independently with an experimental research project. The student can design, initiate and manage an experiment. The student can evaluate and utilize obtained results in a scientific perspective. The student will gain experience working in groups to solve a scientific problem.
In addition the student will get competence in a variety of fish physiological questions in context with environmental variables.

- Type of assessment
- Written assignment, 3 weeks (report)Written examination, 2 hours (multiple choice)Report and written examination assessed with 1/3 and 2/3 respectively.
The written assignment and the written exam must be passed separately. The part exams need not to be passed in the same exam period.
- Exam registration requirements
Participation in at least 80% of the lectures and seminars is required.
- Only certain aids allowed
The multiple choice exam is without any aids (no textbooks, notes or similar).
For the report (3 weeks assignment) all aids are allowed.
- Marking scale
- 7-point grading scale
- Censorship form
- No external censorship
Several internal examiners
As ordinary exam.
A new or revised report must be handed in no later than two weeks before the reexamination.
If the requirement of participation in at least 80% of the lectures and seminars are not fulfilled, the student must take the course again the next year.
Criteria for exam assesment
In order to obtain the grade 12 the student should convincingly and accurately demonstrate the knowledge, skills and competences described under Learning Outcome.
