Abstract: Fish passages are considered the oldest management tool used to minimize the impact of blocking fish migratory routes by hydroelectric power plants. However, fish passages are being installed without specific criteria in Brazil, with severe consequences to the conservation of the local fish fauna. Therefore, basic data gathered for fish passages already constructed could contribute to define operational rules, in addition to offer subsidies to decision-making and design of future facilities. Thus, the fish lad… Show more

“…Silva et al . () also showed that spillway and turbine discharges increased the abundance of fish downstream from Baguari Dam located in Doce River Basin, Minas Gerais, Brazil. Direct study of fish movements in other systems also indicates that fish are attracted to the tailraces of hydropower facilities during high flows (Linnik et al , ; Rivinoja et al , ; Thorstad et al , ; Scruton et al , ).…”

“…Finally, spillway discharge was also included as a continuous predictor in our analyses. Silva et al () observed an influence of spillway discharges on the abundance of fish downstream from the TMD. We calculated the mean of spillway discharge per day and diel period.…”

“…The control that such projects exert over flow has effects widely reported in the literature. Such effects range from changes in fluvial geomorphology to reduction in species abundance and diversity (Agostinho et al., ; Gubiani, Gomes, Agostinho, & Okada, ; Santos et al., ; Schilt, ; Silva, Nogueira, Maia, & Resende, ). Changes in the functional characteristics of biological communities can also alter ecosystem processes (Cardinale et al., ).…”
