Abstract (en):
We present information on the diversity of fishes in Caño La Guardia, a tributary of the Capanaparo River (Orinoco basin), a river of moderately black waters located in southeastern Apure state, Venezuela. We found 174 species pertaining to 39 families and ten orders. The orders of most importance were Characiformes (94 species), Siluriformes (34 species), Perciformes (24 species) and Gymnotiformes (12 species). Samples were collected from three types of habitat: sandy beaches, main river channel and sites associated with the morichito palm tree (Mauritiella aculeata). Our results showed significant differences of species composition among the habitats evaluated. Some 41 species were found only at sites associated with morichito palms, and all of those are of high value in the ornamental fish trade. This study increased the number of fishes for the Capanaparo River sub-drainage by forty species.

Se presenta información sobre la diversidad de peces en el Caño La Guardia, afluente del río Capanaparo (cuenca del Orinoco), un río de aguas moderadamente negras al suroeste del estado Apure, Venezuela. En este estudio se reportan 174 especies distribuidas en 39 familias y diez órdenes. Los órdenes con mayor importancia fueron Characiformes (94 especies), Siluriformes (34 especies), Perciformes (24 especies) y Gymnotiformes (12 especies). Para el muestreo se consideraron tres tipos de hábitat: bancos de arena, cauce principal del río y lugares con asociaciones la palma morichito (Mauritiella aculeata). Los resultados mostraron diferencias significativas en la composición de especies entre los tipos de hábitat evaluados. Unas 41 especies de peces fueron encontradas únicamente en morichales, todos ellas con alto valor para la pesca ornamental. Asimismo, este estudio aumentó en más de 40 especies la lista de peces para la subcuenca del río Capanaparo.
