Fish migration is essential to maintain healthy aquatic ecosystems, but hydraulic structures
across rivers have impeded natural fish migration worldwide. While efforts have been made …

Abstract Przewalski's Naked Carp (Gymnocypris przewalskii) is a typical migratory fish
species of the Qinghai Lake region (China). This study focused on the Gangbei Channel …

Effective fishways rely on attracting fish, utilising the natural rheotactic behaviour of fish to
orient into an attraction flow near the entrance. Despite the critical importance of attraction …

The modification and utilization of rivers in regions where small-bodied diadromous fish are
prevalent has largely occurred without fully understanding the migration behaviour of these …

Understanding how fish traverse man-made barriers (eg road-crossings and culverts)
ensures that engineering and design guidelines achieve positive outcomes for fish …

Freshwater ecosystems have been severely fragmented by artificial in-stream structures
designed to manage water for human use. Significant efforts have been made to reconnect …

Weir construction has fragmented many rivers, resulting in the exclusion of some fish
populations from suitable habitat. A cheap retrofit fishway for small, slo** weirs is the Low …

Inadequately designed culverts can be physical barriers to fish passage if they increase the
velocity of water flow in the environment, alter natural turbulence patterns or fail to provide …

A culvert is a covered road structure constructed to pass flood and drainage. The
engineering design principle of culverts focuses on optimising flood capacity at the lowest …

Increasingly, cold-water pollution (CWP) is being recognised as a significant threat to
aquatic communities downstream of large, bottom-release dams. Cold water releases …
