Methodology for Target Strength Measurements (With special reference to in situ techniques for fish and mikro-nekton)

This report has been produced as a result of discussions in the Fisheries Acoustics Science and Technology (FAST) Working Group of the lnternational Council of the Exploration of the Sea (ICES). Following discussions in the FAST Working Group, it was proposed that a study group on Target Strength Methodology be formed, which was recommended by the Fish Capture Committee. This resulted in ICES Resolution C Res 1992 2:ll: "A Study group onTarget strength Methodology is established under the Chairship of E. Ona (Norway) and will meet in Gothenburg, Sweden on 19 April 1993 to prepare a report, with a view to publication in the ICES Cooperative Report Series on the methodology for Target Strength measurements with special reference to in situ techniques for fish and micro- nekton"
