Abstract (en):
The list of freshwater, estuarine and marine fishes known from the Orinoco river delta in Venezuela is updated, corrected and expanded. Based on recent field work, revision of the literature and museum collections, a list of 438 species was assembled that includes nine new records for the region. These are grouped in 20 orders, 82 families and 281 genera. The orders with the most species are Characiformes (132), Perciformes (99) and Siluriformes (87). Most of the fishes were found in freshwater (71 %) with estuarine and marine species amounting to only 39 %. About one third (29 % - 127 sp.) have economic importance as fishery resources. Four introduced species were found, three exotic and one transported from another Venezuelan drainage.

Se actualiza, corrige y amplía la lista de peces dulceacuícolas, marinos y estuarinos del delta del río Orinoco, Venezuela. Con base en el trabajo de campo, revisión bibliográfica y de colecciones, se elabora una lista de 438 especies, de las cuales nueve son nuevos registros para la región. Estas están agrupadas en 20 órdenes, 82 familias y 281 géneros. Los órdenes con mayor representación específica fueron Characiformes (132 sp.), Perciformes (99 sp.) y Siluriformes (87 sp.). En función de la salinidad se obtuvo que la mayoría de las especies (71 %) fueron de hábitos estrictamente dulceacuícolas, seguidas por las de hábitos estuarinos y marinos (39 %). Un tercio de las especies (29 % - 127 sp.), presentan importancia como recursos pesqueros. Se registran cuatro especies introducidas (tres exóticas y una trasplantada).
