Results from Bottom Trawl Survey on Flemish Cap of July 2004
A stratified random bottom trawl survey on Flemish Cap was carried out from June 25th to August 2nd 2004. This year, the area surveyed was extended up to depths of 800 fathoms (1400 meters) following the same procedures as in previous years and increasing the number of hauls planned (195). The surve...
