Abstract: 1. The role of fish translocation upstream of dams, for the conservation of migratory species, is controversial. An important but still unaddressed question is whether migratory patterns are affected, after the translocation events, by a hydropower dam. In existing dams, a useful means to test this might be to compare the behaviour of translocated fish with those in undammed river segments in the same region.2. The objective of this study was to evaluate the effectiveness of fish translocation in promoting acc… Show more

“…There is no easy solution, as indicated by recent studies (Reis et al, 2016;Pelicice et al, 2017Pelicice et al, , 2021. Dams cause multiple impacts that act synergistically to limit or prevent fish recruitment, including restrictions on upstream and downstream migration of adults and young (Pelicice, Pompeu & Agostinho, 2015), genetic isolation (Rosso et al, 2017;Baggio et al, 2018), the loss of critical habitats (Du et al, 2013), changes in environmental triggers and conditions (Dugan et al, 2010;Tamario et al, 2019), and anomalous behaviour in reservoirs and fishways (Hahn et al, 2020;Lopes et al, 2021;Silva et al, 2021). The conservation of migratory fish in degraded environments is a complex topic, requiring the maintenance of natural processes that take place at different temporal and spatial scales, such as migration, spawning, drift, growth and dispersal, and in a range of different environments and conditions (Pompeu, Agostinho & Pelicice, 2012;Lopes et al, 2018).…”

“…Therefore, protecting species showing reduced natural stocks and/or endangered species, such as B. orbignyanus (EN/CR) and P. corruscans (Spix & Agassiz, 1829) (VU) is an important service provided by Conservation Units (Akama et al 2018). Maintaining tributaries without artificial dams, where fish can complete their life cycle, is the most viable and effective alternative for species conservation (Marques et al 2018, Lopes et al 2021. São Francisco Falso River, which is the main tributary near "Refúgio Biológico de Santa Helena", is an example of free-dam river it that can help protect the fish fauna of the region.…”

“…Depending on the dimensions of the flooded area and the water reservoir residence time, many fish species may not find the trophic and environmental resources to which they are adapted or require (Santos et al, 2018). Flooded areas can act as mazes where fish have few chances to find the exit to continue their way (Pelicice, Pompeu & Agostinho, 2015; Lopes et al, 2021). A holistic solution to these impacts would need to allow safe, directed, undistracted and bidirectional fish migration between different habitats (Lucas et al, 2001; Makrakis et al, 2007; Tamario et al, 2019); that is to say, it would need to allow a complete two‐way migration (Calles & Greenberg, 2009; Fjeldstad, Pulg & Forseth, 2018), enabling fish to move safely both downstream and upstream of the barriers (Katopodis & Williams, 2016; Silva et al, 2018).…”

“…The physical characteristics of reservoirs (e.g. extension, low visibility or flow conditions) can make it difficult for fish to find the way out upstream from the reservoir or the fishway entrance when migrating downstream (Kraabøl et al, 2009; Pelicice, Pompeu & Agostinho, 2015; Williams & Katopodis, 2016; Li et al, 2020; Lopes et al, 2021).…”
