Ichthyofauna of piedmont and savannah environments in the Casanare River drainage, Orinoco Basin, Colombia ; Ictiofauna de los ambientes de piedemonte y sabana en el drenaje del río Casanare, cuenca del Orinoco, Colombia
Currently, only 20 fish species have been recorded from the Casanare River, which is one of the main tributaries of the Meta River drainage. To characterize the fish assemblages of this river, samplings were carried out at 35 collecting stations in low and high water seasons of 2015. The results obtained, raised the number of fish species of the Casanare River drainage to 180, of which 41 are exclusive to the piedmont, 83 to the savannah and 56 are shared between both units; 19 species are endemic, 11 are migratory, and three are classified in one of the national threat categories. Three speci... Mehr ...

Currently, only 20 fish species have been recorded from the Casanare River, which is one of the main tributaries of the Meta River drainage. To characterize the fish assemblages of this river, samplings were carried out at 35 collecting stations in low and high water seasons of 2015. The results obtained, raised the number of fish species of the Casanare River drainage to 180, of which 41 are exclusive to the piedmont, 83 to the savannah and 56 are shared between both units; 19 species are endemic, 11 are migratory, and three are classified in one of the national threat categories. Three species were found to be undescribed and one represents a new record for the Orinoco River Basin in Colombia. This study fills the lack of information for the Casanare River drainage, highlights its importance as a potential area for biodiversity conservation and facilitates the decision-making process related to the management planning and conservation of the hydrographic basin ; Actualmente, sólo se han registrado 20 especies de peces para el río Casanare, uno de los principales afluentes de la cuenca del río Meta. Con el fin de caracterizar los ensamblajes de peces de este río, se realizaron muestreos en 35 estaciones de colecta en los períodos de aguas bajas y altas del 2015. Los resultados obtenidos incrementaron el número de especies de peces de la cuenca del río Casanare a 180, de las cuales 41 son exclusivas del piedemonte, 83 de la sabana y 56 son compartidas entre ambas unidades; 19 especies son endémicas, 11 son migratorias y tres están clasificadas en una de las categorías de amenaza nacional. Se encontraron tres especies no descritasy una representa un nuevo registro para la cuenca del río Orinoco en Colombia. Este estudio llena el vacío de información para la cuenca del río Casanare, destaca su importancia como área potencial para la conservación de la biodiversidad y facilita el proceso de toma de decisiones relacionado con la planificación de manejo y conservación de la cuenca hidrográfica.
