Low light levels increase avoidance behaviour of diurnal fish species: Implications for road culverts

The paper tests how low light levels in culverts affect fish behavior, finding diurnal species avoid dark areas and require ~100-200 lux to pass through, while most culverts lack sufficient light.

Swimming performance traits of twenty-one Australian fish species: a fish passage management tool for use in modified freshwater systems

Utilising the boundary layer to help restore the connectivity of fish habitats and populations

The paper presents a novel culvert remediation design that improves fish passage for small-bodied and juvenile fish at high velocities by utilizing boundary layer velocity reduction, outperforming traditional baffle systems.
