Spring.
This course has a limited capacity, enrolment is based on application. The application deadline is Wednesday in week 2 for the spring semester.
It is compulsory to attend the first lecture/orientation meeting, or you risk losing your seat. If you are unable to attend the first lecture, you must contact the Study Section (
The course aims to provide a fundamental introduction to how we monitor fish stocks, both by fisheries dependent and fisheries independent methods. A focus will be to provide the students with a comprehensive understanding of how acoustic and capture- based fisheries independent monitoring methods are applied to support sustainable fisheries.
Age-structured stock assessment models are an essential scientific basis for responsible harvesting, and the course will give an overview of survey design and methods providing abundance indices by age in acoustic - and trawl surveys. Other survey methods will also be presented.
FAO¿s classification system of gear types, and the requirements for a responsible, sustainable resource- and environment-friendly fishery, will be presented. The construction and function of different gear types, and the biological capture characteristics of these will be described. The importance of different fish behaviour and reaction towards gear stimuli and vessel avoidance will be emphasized, and how this affects catchability, selectivity and survey results. Selection attributes in different gear types and estimation of gear selectivity probabilities will be covered.
The lectures will also introduce physical and biological principles for hydro-acoustic detection and measurement of marine organisms, with focus on abundance estimation of fish and plankton. The course will include practical assignments on the function and operation of scientific echo sounders and echo integrators.
Finally, the course will introduce new technological developments in the field of hydro-acoustics, gear types, and optical tools, and how these will provide new possibilities to observe and understand aquatic ecosystems under change.
A mandatory 2-day student cruise will be carried out, and the students will in co-operation produce a scientific survey report. The report shall be presented orally and in writing.
