Abstract

The nature semi-closed of the Gulf of México, together with its oceanographic pattern and freshwater discharges, provide a rich region considering biodiversity. However, the demersal fish community structure is almost not known, even that this great ecosystem has been continuously impacted by oils spills and over exploitations of fishery resources. The present study was developed to evaluate spatial variation of the demersal fish community and with depth gradientin area of the Platform and Channel of Yucatan, southern Gulf of Mexico. Sampling was realized in 18 stations with an oceanographic ship using a shrimp trawl at 99m as average depth. A total of 129 species were recorded, where Serranidae family was the most diverse (10 species), following in importance Paralichthyidae (eight species), Sparidae and Triglidae with seven species each.
