| Sumario: | This study describes the geographic and bathymetric distribution patterns of abundance of the main macrourid species found in Atlantic African waters. A series of demersal trawl surveys, carried out in waters off Morocco, Western Sahara, Mauritania, Guinea Bissau, Gabon, Angola, and Namibia provided the catch data analysed. The survey area was between latitudes 35°56′N and 29°39.50′S and the sampled depths from 20 to 2000 m on the continental shelf and the slope. We collected 50 macrourid species belonging to 15 genera. The most abundant species was Nezumia micronychodon, with 91980 specimens caught, followed by Nezumia duodecim, Trachyrincus scabrus, and Hymenocephalus italicus with 31461, 28411, and 25349 specimens, respectively. The bathymetrical distribution ranges are extended for 21 species of grenadiers. |
