Nature-like fishways are hydraulic structures built in order to allow fish to negotiate river obstructions. Being different than common fishways designs, nature-like fishways imitate natural rivers characteristics as they ...

Aim: β diversity was used as an indicator to test the hypothesis that a fishway can increase river connectivity, as a reduction in the value of this metric indicates greater similarity among fish assemblages. Methods: ...

Longitudinal river fragmentation through physical barriers is a major issue for the conservation of aquatic species in regions with intense hydropower development, such as Chile. The construction of fishways is the main ...

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. ...

Our understanding of biological design criteria to facilitate fishway passage design is limited, partially due to the lack of understanding of biological motivators, cues and constraints, as well as a lack of biological ...

Freshwater ecosystems have become severely fragmented by artificial instream structures. Significant efforts have been made to reconnect freshwater systems to support fish movement through the design and installation ...

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 ...

Fishways provide a better environmental surrounds to streams and rivers that were intercepted with weirs or dams. It is achieved providing the migration of fish through these systems. Fish swim capabilities correlated to ...
