La composición de especies de peces del Guadiamar therefore, reflect not a temporary, but a consolidated fish assemblage (Pérez-Alejandre, 2009). Sampling sites results suggest the predominant lack of exotic fish species in the upper section of the basin (except the Agrio reservoir) and in the upper reaches of the Guadiamar River tributaries, whereas downstream of the Agrio reservoir and the Aznalcóllar mines, the middle and lower section of the Guadiamar River connected with the Doñana marshland, may be considered as exotic fish species sources (Table 3).

Las comunidades de peces del río Guadiamar y el accidente minero de Aznalcóllar sense or environmental quality control of polluted inputs will have to be dealt with as a management priority. The present study may serve as a comparative species richness index against which future fish assemblage drifts may be evaluated. Acknowledgments Data presented in this study was collected under projects: i)“Caracterización ecológica de las comunidades de peces en el río Guadiamar”, ii)“Fauna piscícola de la cuenca del río Guadiamar: estado de conservación, problemática y directrices de restauración”, iii) “Seguimiento del efecto del vertido tóxico de las minas de Aznalcóllar sobre la comunidad de peces del río Guadiamar” and iv)“Bases para la elaboración de un plan de conservación de los peces continentales autóctonos de Andalucía”, all of them funded by the Andalusian Regional Government.
