Abstract

The objectives of this study were: 1) to establish the composition and distribution of fish populations in the upper Segura river basin, and 2) to characterize the conservation status of the sampling sites according to their ichthyofauna. It was detected the occurrence of 13 fish species, 3 native (Luciobarbus sclateri, Salmo trutta and Squalius pyrenaicus), 3 translocated from Iberian basins (Cobitis paludica, Gobio lozanoi and Pseudochondrostoma polylepis) and 7 exotic fish to the Iberian Peninsula (Alburnus alburnus, Cyprinus carpio, Esox lucius, Lepomis gibbosus, Micropterus salmoides, Sander lucioperca and Onchorrhyncus mykiss). Sampling sites were characterized according to the conservation status of their fish communities: Type 1, good condition which are dominated by native fish species; Type 2, intermediate condition which are dominated by non-native fish species but significant populations of native fish species inhabiting in these sectors; Type 3, poor condition where sampling sites were dominated by exotic fish species.
