Fish passage research is important to mitigate the adverse effects of fragmented river
habitats caused by waterway structures. The scale at which this research is undertaken …

River fragmentation is an increasing issue for water managers and conservationists. Barriers
such as dams interfere with freshwater fish migration, leading to drastic population declines …

Migration barriers being selective for invasive species could protect pristine upstream areas.
We designed and tested a prototype protective barrier in a vertical slot fish pass. Based on …

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

The cumulative effect of culverts in impeding upstream fish passage is similar to that of large-
scale high-head instream structures. The common solution to overcome this impediment is …

Culverts are a major cause of habitat fragmentation in freshwater ecosystems, are a barrier
to fish movement, and can be regarded as a significant contributor in the decline of …

The challenge to understanding the fluid mechanics of fish swimming is knowing exactly
what the water is doing where the fish swims. Recent field observations and large-size …

A culvert is a covered channel to pass streams and floodwaters through an embankment.
The ecological impact of culverts has been recognised, in particular in terms of stream …

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 …

Fish are thought to exploit low velocity recirculation zones in the wakes of baffles to take
refuge from challenging hydraulic conditions in baffled culverts. Here, we investigate how …
