Calculation of the Calibration Factors from the Comparative Experience between the R/V Cornide de Saavedra and the R/V Vizconde de Eza in Flemish Cap in 2003 and 2004
EU carries out a stratified random summer bottom trawl survey in Flemish Cap, Division 3M of the NAFO Regulatory Area, since 1988. Since 1991, the survey was made with the R/V Cornide de Saavedra. In 2003, this vessel was replaced for the R/V Vizconde de Eza, so, in order to maintain the series obta...
