Abstract

Although the Aiuruoca River is recognized as a very important area for fish fauna, the species composition of this river remains unknown or restricted to technical reports of licensing projects. The aim of this study was to describe the composition and distribution of the ichthyofauna in the Aiuruoca River basin. Fifty-eight collection points were sampled along the Aiuruoca River basin during 2010 and 2011, including 38 streams, 11 lagoons and 9 points along the Aiuruoca River main channel. A total of 8562 specimens were collected belonging to 6 orders, 15 families, 33 genera and 47 species. The pirapetinga fish (Brycon nattereri) is listed on Brazil’s endangered species, and the rainbow trout (Oncorhynchus mykiss) was the only exotic species captured. Altitude is one of the main factors that influence fish community structure in the Aiuruoca River basin, confirming its importance for fish conservation
