Course content

Fish are of considerable importance to humans as a source of food, both from capture fisheries and through various forms of culture. Rational exploitation and management of fish stocks, irrespective of whether they be wild or captive, relies upon detailed insights into, and knowledge about, their biology. This course is an initial step towards giving you that knowledge. The course gives an introduction to the life-styles of fishes, with an emphasis on anatomy and physiological adaptations to different aquatic habitats. The following themes are covered: fish diversity and distributions, swimming, osmoregulation, respiration, feeding and digestion, reproduction and larval development, and life-histories.

The laboratory course will give you an introduction to practical work in the laboratory, data analysis and the writing of reports.

You will write a term-paper (essay) on a central theme within fish biology by selecting a topic of your choice from a suggested list of titles.
