Resumen
En la cuenca del río Culebra perteneciente al cantón Taura, se realizó un estudio con el objetivo de conocer la diversidad de peces presentes, ya que no se encontraron estudios previos sobre este recurso en esta zona del país. Se realizaron 5 salidas de campo durante Junio - Octubre del 2016 tomándose como referencia 6 puntos de muestreo. Para la captura de los peces se utilizaron dos artes de pesca: red chinchorro y atarrraya. Posteriormente fueron transportados hasta el laboratorio de acuacultura de la Facultad de Ciencias Naturales para ser identificados con claves taxonómicas. Se registró un total de 437 individuos identificando nueve especies, tres órdenes y cinco familias. La Familia Characidae fue la más diversa con cuatro especies: Bryconamericus brevirostris, Rhoadsia altipinna, Brycon alburnus y Brycon dentex. Las especies más abundantes fueron Oreochromis sp, y Brycon alburnus, mientras que Hoplias microlepis y Pimelodella elongata, fueron las menos abundantes.
In the Culebra river basin belonging to the Taura Canton, an ichthyological study was carried out with the objective of knowing the diversity of fish present, which no longer existed in the country. Five field trips were made in June - October 2016, taking as a reference 6 sampling points. For the capture of the fish is used in the fishing gear: red chinchorro and red with atarraya. Later they were transported to the aquaculture laboratory of the Faculty of Natural Sciences to be identified with taxonomic keys. A total of 437 individuals were registered identifying nine species, three orders and five families. The Characidae Family was the most diverse with four species: Bryconamericus brevirostris, Rhoadsia altipinna, Brycon alburnus and Brycon dentex. The most abundant species were Oreochromis sp and Brycon alburnus, while Hoplias microlepis and Pimelodella elongata, were the least abundant.
