Bidirectional connectivity in fishways: A mitigation for impacts on fish migration of small hydropower facilities Open
Most freshwater fish need to move freely through rivers to complete their life cycles. Thus, river barriers (e.g. dams, culverts and gauging stations) may delay, hinder or even block their longitudinal movements, affecting fish conservatio…

Two-Way Migration of a Potamodromous Cyprinid in a Small Hydropower Plant with a Pool Type Fishway Open
Most freshwater fish need to move freely through rivers to complete their life cycles. Thus, river barriers that hinder or block their longitudinal movement (e.g., dams, culverts, gauging stations), directly affect their reproductive, feed…

Bidirectional connectivity via fish ladders in a large Neotropical river: Response to a comment Open
In a recent article, we described fitting electronic tags to the fish Prochilodus lineatus to document how a fishway connected aquatic habitats downstream and upstream of a major dam. Moreover, given that tagged fish remained upstream or d…

Passage Performance of Technical Pool-Type Fishways for Potamodromous Cyprinids: Novel Experiences in Semiarid Environments Open
Endemic freshwater fish from semiarid environments are among the most threated species in the world due to water overexploitation and habitat fragmentation problems. Stepped or pool-type fishways are used worldwide to reestablish longitudi…

Hydropower Development and Fishways: A Need for Connectivity in Rivers of the Upper Paraná Basin Open
South American rivers have become intensely affected by the construction of hydroelectric dams that block the river’s connectivity for migratory fish species. In order to mitigate the problems caused by dams and to reestablish connections …

Environmental Assessment in Neotropical Watersheds: A Multi-Factorial Approach Open
This study evaluated the environmental conditions of two watersheds selected on the basis of similarities in land use. The environmental conditions of the watersheds were analyzed using two geoprocessing methods and in situ evaluations by …

Stress indicators for Prochilodus lineatus (Characiformes: Prochilodontidae) breeders during passage through a fish ladder Open
This study investigated whether fish ladder transposition is a stressful event for the streaked prochilod, Prochilodus lineatus, in a dam on the Upper Paraná River, Brazil. Bodyweight, standard length and plasma concentrations of cortisol,…

Effectiveness of a fish ladder for two Neotropical migratory species in the Paraná River Open
We evaluated the effectiveness of the fish ladder at Porto Primavera Dam in the severely regulated Upper Paraná River, for two Neotropical migratory fish species. Overall, 564 fish (448 Megaleporinus obtusidens and 116 M. piavussu) were PI…
View article: Fish ladder as connectivity in a large Neotropical river: upstream and downstream movements of Prochilodus lineatus
Fish ladder as connectivity in a large Neotropical river: upstream and downstream movements of Prochilodus lineatus Open
The potamodromous species worldwide has been threatened by dams intercepting large rivers. One strategy of mitigation is providing passage through fish ladders; however, ladders in Neotropical rivers have been considered as only ascending …
