| Summary: | A stratified random bottom trawl survey on Flemish Cap was carried out from July 1st to August 21th 2005. The area surveyed was extended up to depths of 800 fathoms (1 400 meters) following the same procedures as in previous years and increasing the number of hauls planned (195). The survey was carried out by the R/V Vizconde de Eza with the usual survey gear (Lofoten). A total of 176 valid hauls were made by the vessel R/V Vizconde de Eza, 117 up to 730 meters depth and 59 up to 1 400 meters. Survey results including abundance indices of the main commercial speci es 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) and the total area surveyed (strata 1-34, up to depths of 1 400 m). |
