Culverts used to convey river water under roads and embankments are one of the most
common small-scale barriers to longitudinal fish movements worldwide. Using an open …

Considerable effort has been expended to construct culverts and fishways that allow for fish
passage. However, the designs have seldom considered behaviour, energetics, and …

Finding the entrance into a fishway might be challenging for upstream migrating fish and
especially so in large rivers. Auxiliary discharge, added into the downstream section of the …

In recent years, fishways have increasingly been designed and installed with the intention to
not only provide economically important fishes, such as salmonids, with free passage at …

Road crossings and culverts are common man-made structures along river courses, ranging
from national highways to rural roads and urban networks. Present expertise in culvert …

Globally, populations of diadromous anguilliform morphotype fish, such as eel and lamprey,
have experienced substantial declines, partly as a result of habitat fragmentation caused by …

Many rivers are heavily fragmented, resulting from anthropogenic cross‐channel structures.
Cost‐effective solutions are needed to restore habitat connectivity for migratory fishes …

The restoration of fish passage has been focused on anadromous fish species, whilst
studies accommodating passage of coarse species have often been considered incidental …

Movement between habitats in river fish assemblages is often restricted by instream
structures such as culverts. The ability of diadromous common jollytail, Galaxias maculatus …

Design methods that account for the ability of fish to swim upstream through culverts are
based on tests describing how fast and for how long different fish species can swim. These …
