Application deadline

Applicants from Nordic countries: 1 June for the autumn semester and 1 December for the spring semester. Applicants from outside the Nordic countries: 1 October for the spring semester and 15 April for the autumn semester.

Type of course

This subject is obligatory in the Master's programme in International Fisheries Management" (IFM).The course can also be taken as a singular course

Admission requirements

Application code: 9371
Entrance requirements as for the M.Sc.programme in International Fishery Management.

Course contents

An introduction is given to the methods traditionally used to investigate exploited aquatic organisms. This includes laboratory methods for determination of population parameters, and field work for direct estimation of fish density. The concept of a fishery model is introduced. We adapt this theory to widely diverse species and international fisheries, and make simple quantitative predictions of the suitability of different exploitation regimes. Harvest technology deals with a general description of the vessel and gear technology used in different parts of the world. We deal with fish behavior, types of materials, operation methods, selectivity, and fish detection and density estimation with hydro-acoustics. New developments in the pursuit of energy efficient and environmentally friendly gear, as by-catch reduction, and user friendly gear, will be addressed.

Objective of the course

This is an introductory course designed to level the knowledge of the students on aquatic biology and technology, irrespective of their academic background. The student becomes acquainted with different fishing methods and drilled on the basic field techniques, analytical tools, vocabulary and advice given by fishery scientists. This facilitates their participation in multi-disciplinary teams dealing with natural resources. The course is also a requirement for later courses on ecological assessment and population management. In addition to experience fieldwork and fishing, students rehearse some general research methods and skills.

Language of instruction

The language of instruction and all syllabus material is English.

Teaching methods

Lectures, seminars, practical labs and research cruise, as well as self-study of basic concepts.

Students have to submit one field report after the research cruise.


Written examination, 4 hours.
The grading scale is A-F, where A-E is passed, and F is failed.
A re-sit exam is arranged in the next semester.

Date for examination

En skriftlig prø
ve 01.12.2015

The date for the exam can be changed. The final date will be announced in the StudentWeb early in May and early in November.
