The dataset represents the number, the total and the standardized biomass (catch per unit effort) of 94 deep-pelagic fish species collected by pelagic trawling in submarine canyons of the Bay of Biscay slope during the EVHOE scientific cruises on R/V Thalassa in autumn between 2002 and 2019 (https://doi.org/10.18142/8). Fifty-six trawls were conducted at night between 20 m and 2000 m depth. The trawl net was 192 m long with a headline of 76 m and a foot rope of 70 m. The average vertical mean mouth opening was about 24 m and the horizontal opening of about 58 m. The mesh size gradually decreases from very large 8 m meshes at the mouth to 20 mm meshes in the codend. To allow the capture of very small specimens, the trawl is also equipped with a 7.5 m long sock with a 12 mm mesh. The trawl had an average vertical mouth opening of 24 m and a horizontal opening of 58 m. The duration of the haul was 1 hour at 4 kn. The trawl did not have an opening-closing mechanism. Therefore, some individuals might have been ...
