Effectiveness of a multi-slot vertical slot fishway versus ... The present study compares the passage performance of the Iberian barbel, Luciobarbus bocagei (Steindachner, 1864), a potamodromous cyprinid, negotiating two different types of vertical slot fishways (VSF): a standard VSF and a multi-slot VSF (MSF). Results show that differences exist between configurations in the number of fish movements ... Hydraulics of the Vianney‐Legendre vertical slot fishway ...
