Abstract

One of the most relevant threat factors for the migratory fishes is the presence of barriers as dams and weirs which frequently are no permeable for their movement.Nowadays, one of the most frequent mitigation measures to avoid the barrier effect caused by dams and weirs is theincorporation of fish passes as fishways to these water infrastructures. The lack of knowledge about the behaviour of fishes in these facilities results in an imperfect design. Specially, it happens in cyprinid rivers because of most of the time the usual design criteria are only considering salmonid rivers.It have been studied with this aim the differences observed in indigenous fishes ascending a vertical slot fishway built in theHidraulic Laboratory of the Center for Hydrography Studies. The three species studied have been one salmonid, the brown trout (Salmo trutta), and two cyprinids, the common barbel (Luciobarbus bocagei) and the Iberian nase Pseudochondrostoma polylepis).
