Abstract (en):
Between february and december of 2011 the fish communities of the ciénaga de Paredes, were studied by four samples in periods contrasting climates, station 1, corresponding to the inlet of the pipe Peruétano (BCP), station 2, Swamp Center (CC) and station 3, the mouth of the creek Gómez (DQG).They were captured 762 individuals, the 67%, 28%, and 4% corresponded to the orders Characiformes, Siluriformes and Perciformes respectively,
the remaining 1% corresponds to the orders of Gymnotiformes and Myliobatiformes. It was found 29 species, of which, Prochilodus magdalenae, Ageneiosus pardalis, Curimata mivartii, Ctenolucius hujeta, Cyphocharax magdalenae and Hoplias malabaricus were the most dominant (abundant and frequent). It was established that changes in the conformation of the associations of fishes were evident between climatic periods between environments. From multivariate Canonical Correspondence Analysis (CCA), temperature, depth, turbidity and DQO are the physical and chemical variables that best explain the relationship between the environmental characteristics of the swamp and species associations.
Abstract (es):
Entre febrero y diciembre de 2011 se estudió la comunidad de peces de la ciénaga de Paredes, a través de cuatro muestreos, en periodos climáticamente contrastantes y tres ambientes: estación 1, correspondiente a la boca de entrada del caño Peruétano (BCP); estación 2, centro de la ciénaga (CC) y la estación 3, desembocadura de la quebrada la Gómez (DQG). Se capturaron 762 individuos, pertenecientes a los órdenes Characiformes (67 %), Siluriformes (28 %), Perciformes (4 %) y el 1 % restante a Gymnotiformes y Myliobatiformes. Se obtuvo registro de 29 especies, de las cuales, Prochilodus magdalenae, Ageneiosus pardalis, Curimata mivartii, Ctenolucius hujeta, Cyphocharax magdalenae y Hoplias malabaricus, fueron las más abundantes y frecuentes. Se estableció que los cambios en la conformación de las asociaciones fueron más evidentes entre periodos climáticos que entre ambientes. A partir de un análisis multivariado de Correspondencia Canónica (ACC), se mostró que la temperatura, la profundidad, la turbiedad y la demanda química de oxígeno (DQO) son las variables físico-químicas que mejor explican la relación entre las características ambientales de la ciénaga y las asociaciones de especies.
