The area surveyed was extended up to depths of 800 fathoms (1400 meters) following the same procedures as in previous years and decreasing the number of hauls planned (175). The survey was carried out by the R/V Vizconde de Eza with the usual survey gear (Lofoten). A total of 167 valid hauls were made by the vessel R/V Vizconde de Eza, 111 up to 730 meters depth and 56 up to 1400 meters. Survey results including abundance indices of hte main commercial species and age distributions for cod, redfish, American plaice, Greenland halibut and shrimp are presented. The general indexes for this year are estimated taken into account the traditional swept area (strata 1-19, up to depths of 730 m).
