Report of the Study Group on Target Strength Estimation in the Baltic Sea (SGTSEB)

The Study Group continues to work by correspondence.The 2002-report and a summary report on the work at the 2003 meeting in Bergen are made available to the 2003 ACS-meeting in Tallinn.The group recommends a TS-relation based on fewer terms than suggested in the 2002-report and to consider some effects included then as corrections to the biomass calculations instead of the target strength.A final report based on previous material and new data presented during the 2003-meeting will be compiled and presented within 1 year. It is recommended that this report is submitted as a Cooperative Research Report.
