New distribution data on Spanish autochthonous species of freshwater fish

Abstract

Over the last two years (2008-2010) we performed a monitoring project to update the Spanish freshwater fish fauna. We have collected in 785 sampling localities homogeneously distributed throughout Spain each year. We find as the most important result of this study the occurrence of several species that constitute new records for some rivers or basins in Spain: Lampetra planeri, Petromyzon marinus, Barbus haasi, Iberochondrostoma lemmingii, Squalius alburnoides, Squalius carolitertii, Squalius malacitanus, Cobitis calderoni, Cobitis paludica, and Salaria fluviatilis. Finally we corroborate the existence of Barbatula barbatula in the Duero basin and the assignation of the northeastern populations of this genus to B. quignardi.
