- Fisken og havet (1958- ) 
This report presents the international redfish survey carried out in the Norwegian Sea in August 2008 and the methodology used to review and compare the different hydroacoustic scrutinizing procedures. The results of the comparative analysis clearly show that differences in scrutinizing methods have a very large impact on the abundance estimate of redfish. They probably constitute the major source of uncertainty for any quantitative estimate. Efforts towards standardisation of scrutinizing procedures should be amplified or at least maintained.
