Fishes in MZNA-VERT: freshwater populations in the Erro river (Spain). PhD Project, Pedro Leunda.

Since the Industrial Revolution, humans have affected and destroyed river ecosystems with our activities. The knowledge of the characteristics of non-disturbed rivers is important to assess the biological quality and impacts caused by human activities in rivers.This project aims to assess the ecosystem quality of the Erro River, a well conserved Pyrenean river. The Erro river ecological quality (physicochemical parametres, macroinvertebrate biotic index and fish community) was studied since 2001 to 2003 and in 2005. Ocurrence data of fish was collected to determine the fish community of the river (Leunda, 2011).
