The course, which includes a significant contribution from Marine Scotland’s Science’s Marine Laboratory Aberdeen, introduces students to fishing gear and fish behaviour in relation to gear, and to fishery independent survey methods to assess abundance and distribution. Particular emphasis is given to describing the acoustic survey method.

This course covers fishery independent (survey) methods, with emphasis on the acoustic survey technique. Lectures are given on each of the main survey methods: acoustic, trawl, larvae, egg and TV surveys. The general design concept, relating to all types of survey, is addressed in a lecture and illustrated through a practical as applied to acoustic surveys. Particular attention is then given to the more complex acoustic survey technique. Lectures cover the physics of sound, acoustic instruments, the acoustic properties of fish and methods of biomass estimation. An acoustic survey data analysis lecture is followed by a practical which details the procedures from acoustic measurement to a global estimate of abundance. Lectures are also given covering survey statistics common to all methods, including one on geostatistics. The other part of the course describes the various types of fishing methods, as well as measurement and observation in fishing gear experiments. Various behavioural concepts are covered in relation to the capture process. The concept of selectivity is described in theoretical detail and is then followed by a description of the various selectivity techniques and a review of unaccounted mortality.
Information on contact teaching time is available from the course guide.
The module will be assessed based on 2-graded practicals (70% for analysis and 30% for design)
